In brief: This post will provide some forecast information about Beryl and what to expect in the days ahead, but its main purpose is to try and answer a lot of the questions we’ve been receiving since the landfall of Beryl.

Bye, Bye Beryl

Beryl is whizzing away from Houston. As of 4 pm CT the storm is already 110 miles north of Houston, and pulling away at 16 mph. The storm has weakened into 45-mph tropical system and its weather effects on our region are marginal at this point. Soon they will be nil.

Forecast for this week

It could be worse for mid-July. Losing power during the summertime in Houston is very, very suboptimal, but at least we’re not jumping back into full-on summer heat right away. High temperatures for the rest of this week will be in the low 90s, with a transition to the mid-90s by the weekend. Overnight lows should also drop into the upper 70s for most locations, a few degrees cooler than we’ve been experiencing.

The lower daytime temperatures will be partly due to a fair amount of cloud cover during the afternoons, and a decent chance of showers and thunderstorms each day. (Right now overall accumulations each day look to be on the order of a tenth of an inch, or two, so no real concerns there). Humidity is still going to be very high. Winds are going to go from extreme to near zero by Tuesday morning. In terms of wet bulb globe temperatures, we’re talking high, but not extreme heat.

Is there anything else out there in the tropics to be worried about?

Nope.

We expect to see a lull in tropical activity for at least the rest of this week, if not longer, which is normal for July. Lord knows we’ve earned it. Several people have asked whether Beryl means it’s more or less likely we see another storm this season. I don’t think it makes any difference to our odds. We’ve still got about two and half months during which we need to remain really watchful of the tropics.

Creek and bayou flooding

Most of the creek and bayou flooding we’ve seen on Monday has peaked, or will soon. In the absence of heavy rainfall, and with our winds turning southwesterly, we will see these waters recede pretty quickly this afternoon and evening.

What is up with all these power outages?

I’ve got to tell you, I’m rather surprised by the extent of the power outages today due to downed trees, power lines, and damaged transmission equipment.

As of 2:30 pm CT today, CenterPoint reports that 2.2 million of its Houston-area customers are without electricity, or about 85 percent of them. I’m blown away because, during Hurricane Ike in 2008, there were about 2.1 million customers without power in the immediate aftermath of the storm. If you had asked me before Beryl whether I expected to see comparable outages during this storm, I would have emphatically said no.

Large chunks of the Houston metro area experienced sustained winds of 75 to 90 mph during Hurricane Ike, which made landfall with 110 mph winds. However, during Beryl, the maximum sustained winds that most communities experienced were on the order of 45 to 70 mph. (Beryl made landfall about 80 miles south of Houston with 80-mph sustained winds). So I really don’t understand why a majority of the Houston region is without power this afternoon. Beryl was a serious wind storm, but it was not Ike.

Is my internet coming back anytime soon?

When the power went out, it also took most of our broadband internet providers. The intricacies of internet service are beyond the scope of this site, but generally broadband providers like Comcast need electricity at the local level to deliver internet to your home. So my sense is that, for most communities, high-speed internet won’t come back until the power comes back. I’ve been (not so) patiently checking Xfinity’s site for my service address, and the estimated time of restoration remains an ominous, “as soon as possible.”

As for cell phone towers, you may have just a bar or two of service, which is not really enough to surf the web but still allows you to text and make phone calls. That’s because cell towers are subject to power outages as well. They have backup electrical systems, such as batteries or generators. Some carriers have trucks to service batteries or refill fuel-powered generators, but my understanding is that high-speed cell service may also be dependent on electricity being restored to nearby cell towers. 

Are y’all gonna take a breath now, or what?

Like so many of you, Matt and I both experienced some issues with Beryl. In my case it was several large downed trees and limbs. (Shoutout to my neighbor, Andy, for being handy with his chainsaw so I could use my driveway). I continue to have no internet service, so I drove to Dwight’s house to research and write this update.

The bottom line is that we’re reverting to a normal, daily posting routine starting Tuesday morning. And the posts may be a bit late as we get things back in order. But honestly the forecast is super straightforward: warm-to-hot days, mild nights, high humidity, and a decent chance of showers and thunderstorms with daytime heating.

I want to offer a sincere thank you to everyone who followed along with us during Beryl, a storm that proved a beast to forecast, and which packed a surprisingly strong punch for a Category 1 hurricane making landfall to the south of Houston. I think I speak for everyone but the roofers and tree trimmers when I say, good riddance!

In brief: Everyone in Houston, whether you want to be or not, is a storm chaser this morning. The worst of Beryl should unfold over the next three to six hours, after which we will see improving conditions from south to north. This post describes what to expect during this period of most intense conditions from the storm.

A few thoughts on the arrival of Beryl

Good morning, everyone. Beryl is finally here—not that you need me to tell you that—and so far things are going about as expected. The storm is presently nearing Fort Bend County, and its center will pass through the western half of the city of Houston between now and about 11 am CT. The very worst of Beryl’s effects will be over by then for the city.

Let’s start with some good news. The storm is continuing to move just east of north at about 12 mph, which will allow it to clear the area by this afternoon. We are highly confident in that forward speed. Additionally, the storm did intensify some prior to landfall, but it came ashore as a low-end Category 1 hurricane, with 80-mph winds. Given that Beryl had more than two full days and nights over the Gulf of Mexico to intensify, and with water temperatures in the upper 80s and increasingly low shear conditions, I consider us to be fortunate that Beryl was that strength at landfall. It was starting to intensify, in earnest, as it came ashore. Another 12 to 24 hours and it’s likely a significantly more powerful hurricane.

That may be small comfort if you’re sitting at home this morning without electricity or have some property damage; or if you’re just feeling really miserable as the tempest engulfs you. But this could have been much worse had Beryl gotten to 90 or 100 mph prior to landfall. It’s ultimate track is going to bring the storm’s center and worst winds and rains over large parts of the Houston metro area. This is a very bad track for wind damage with a Category 2 or Category 3 hurricane.

What’s next for Beryl

As the storm encounters land it will start to weaken today. However the storm should remain at or near hurricane strength as it traverses the metro area this morning. The center will move through Fort Bend County, passing near Sugar Land, and up through the western half of Harris County. It will then push into Montgomery County by or before noon before exiting to our north early this afternoon. And then, it will be gone.

Beryl’s winds

Much of the Houston region is starting to see sustained winds above tropical storm force strength this morning, with gusts of 60 mph or higher. These winds should increase a little bit as they reach their peak levels across much of Houston over the next four hours. For areas north of the city, including Montgomery County, peak winds should come a little bit later, perhaps between 10 am and noon CT.

As the winds have increased this morning, the number of power outages in the metro area have steadily increased. As of 5:45 am CT, CenterPoint is up to 396,000 customers without power. Expect that number to increase as Beryl pushes inland. Efforts to restore power should begin as early as later this afternoon as the winds subside.

Heavy rainfall

The strongest band of showers and thunderstorms is now moving through the metro area, roughly along Interstate 45, from Galveston to League City, on into central Houston. These storms are dropping 2 to 3 inches of rain per hour and there are numerous reports of flooded streets. Based on radar trends, I anticipate these rains will slowly lift north with the storm over the next several hours.

Expect the heaviest rainfall to end, from north to south, likely between the hours of 8 am and Noon CT. Additional showers will be possible thereafter, but the worst should be over. Expect accumulations of 4 to 8 inches for most locations, with the potential for some higher bullseyes.

Tornadoes

We’ve already had one tornado warning this morning for areas north of Houston (it has since ended) and we expect some sporadic twisters to spin up as Beryl’s core moves through the city. These will be fast moving tornadoes, and likely only touchdown for a short period of time. If you receive a warning on your mobile phone, please seek an interior room on the lowest level.

Coastal flooding

Storm surge flooding will peak over the next hour or two, with high tide coming in a few hours. These waters will rapidly recede this afternoon as Beryl pulls away.

Our advice this morning

The worst of Beryl is now upon us. Conditions may deteriorate a bit further this morning, before we start to see improvement in conditions by late morning hours. So hunker down for the next 4 to 6 hours, and then we can begin to assess the damage and move forward. If roads are passable (considering flood waters or downed trees) it should be safe to be out and about this afternoon, and especially this evening.

Our next update will come between 10 am and 11 am CT.

In brief: Beryl’s approach to Texas will lead to a messy Sunday night and Monday morning across the Houston region. The storm’s core of strongest winds will pass directly through the city, but we’ve been fortunate to not see rapid intensification (so far) today. This post highlights the latest forecast and threats to the metro area.

Beryl status as of 10 pm CT

As it nears the Texas coast tonight, Tropical Storm Beryl’s maximum sustained winds are 70 mph, which is just below Category 1 hurricane status (winds greater than 74 mph). The storm is moving to the north-northwest at 10 mph, and is only about 70 miles away from the coast. Its central pressure, 986 mb, is slowly dropping indicating ongoing organization.

Beryl’s intensity and track

During our post this afternoon I extolled the virtues of dry air, and the fact that it was helping to slow the intensification of Beryl. Happily, that trend has continued throughout the evening hours. There is still some time for Beryl to rapidly intensify as we have seen with past hurricanes nearing the Texas shore, but time is running out with a landfall expected six to eight hours from now, between 2 am and 4 am CT on Monday. It is likely that Beryl comes ashore as a Category 1 hurricane, and the window is closing on something stronger than this. All that said, tropical systems are unpredictable, so let’s keep cheering on dry air until landfall early tomorrow.

Beryl’s track toward the coast has remained similar for a day now, with a landfall expected near or just east of Matagorda tonight. The center, traveling more or less due north, will pass near locations such as Katy and The Woodlands on Monday morning before exiting to the north.

How much will Beryl blow?

The magnitude of Beryl’s winds, and subsequent power outages, will be determined by the extent to which Beryl strengthens before landfall. It is clear that virtually no part of the Houston metro area, save for the slim possibility of Lake Jackson, is likely to experience hurricane-force sustained winds. However, much of our region is likely to see tropical storm force sustained winds during a period from the wee hours of Monday morning, starting perhaps between 2 to 4 am, through the late morning hours. Our region will see higher gusts during that period.

I went a bit deep on the possibility of power outages in our post earlier today, and my thinking more or less stands. The less that Beryl intensifies before landfall, the better. My hope is that outages will be manageable and restored within a few days. But that is not something I am comfortable guaranteeing.

Rainfall expectations

I have found myself looking at the radar this evening in equal parts awe and dread. Beryl’s center is clearly visible on Houston’s primary radar, which is located in League City. There are three concentric rings of rainbands, and that mess is headed our way over the next 12 to 16 hours.

One of my daughters told me that the prevailing sentiment on TikTok, apparently, is that because the satellite appearance of Beryl looks a lot like Hurricane Harvey from 2017, the Houston area is going to see similar rainfall amounts. God bless the kids, but they’re wrong about that. There is no comparison in the relative storm motions. Because it stalled out, Harvey’s rains unfolded over a five-day period in Houston. By contrast, we’re going to see the worst of Beryl’s rains move through in about 8 to 12 hours. Accordingly, while the rainfall rates may be similarly intense, Beryl’s storms will end much quicker and overall accumulations will be much less.

As of about 9:30 pm CT, the first of these bands was moving inland into Brazoria County, and this will steadily push into Houston tonight and Monday morning. Based upon radar trends, I would estimate that the strongest bands of rainfall will push through the metro are between 4 am and 10 am CT on Monday. Expect accumulations of 4 to 10 inches for much of the area, with higher isolated totals. Rain chances will diminish (but not go away entirely) during the afternoon and evening hours. Expect flooded streets for a time.

Storm surge

Storm surge flooding, on top of high tides on Monday morning, will probably be a bit higher than what our region experienced during Tropical Storm Alberto in many places near and east of where Beryl comes ashore, especially between Galveston and East Matagorda Bay. These flood waters should quickly recede by Monday afternoon or evening as Beryl lifts northward.

Final thoughts

Wherever you’re reading this, I hope you’ve made it home or to a safe place tonight. While this is unlikely to be a catastrophic storm, it still will be memorable due to the fact that Beryl’s center will pass directly over parts of the southwest, western, and northern Houston metro area, and make for a wild night of winds and rain. If at all possible, please stay put through the morning hours on Monday.

Matt will have a post early on Monday, when Beryl makes landfall, and refreshing the forecast. Then, around 6 am CT on Monday, we’ll have a comprehensive update on the storm and its impacts for our region. That will be followed by regular reports on Monday as we get through the worst of the storm, and onto brighter days ahead.

In brief: So far Beryl hasn’t strengthened much today, but there is yet time for intensification before a final landfall tonight. This post goes into the likelihood of such intensification and what it would mean for Houston in terms of winds and the potential for power outages. We also look at the latest rain and surge forecasts.

Beryl status at 4 pm CT

As of this afternoon Beryl remains a tropical storm with 65 mph winds. Its central pressure has dropped a bit to 988 mb, indication a trend toward better organization. The storm is moving to the north-northwest at 12 mph and remains on course to make landfall near Matagorda between midnight and 4 am CT on Monday.

Intensity and track outlook

The fact that we’re not seeing significant increases in Beryl’s winds this afternoon is great news. The biggest threat to the greater Houston area from Beryl is damaging winds, and less intensification means less damage once onshore.

Beryl is running out of time to strengthen—that is not a taunt, mind you. Please let the record show I did not taunt Beryl. The storm will move inland in 8 to 12 hours. There is still time, and the waters are very warm with atmospheric shear low. However, forecasters at the National Hurricane Center note the storm is still struggling to shrug off some dry air in its core. They are still calling for an 85-mph, Category 1 hurricane at landfall, with the likelihood of rapid intensification this evening. This certainly seems plausible, but I am rooting for that dry air to keep disrupting things for just a little while longer.

In terms of track there is very little change to the system. Beryl should come ashore early on Monday, and pass near Katy a little before noon before it lifts further out of the Houston area. This rapid forward movement should continue, allowing the worst effects to begin clearing out of the city during the afternoon hours.

What to expect, and when to expect it

Tropical-storm force winds should reach the coast, near Matagorda Bay, around sunset on Sunday and push into Galveston Island a few hours later. The stronger winds will move into much of the rest of the metro area just before or after midnight tonight. The heaviest rains will arrive around the same time. Please find shelter a few hours before this.

How bad will the winds get?

For this outlook I am going to focus on the possibility of seeing sustained winds of 60 mph or greater, which is likely near the threshold for widespread power outages. The map below shows the National Hurricane Center forecast for the probability of winds of 58 mph or greater from Beryl. I’ve annotated it with circle that roughly denotes Loop 610. Winds at this speed likely will not cause roof damage (that threshold is higher, perhaps 70 to 90 mph sustained winds). The map clearly shows the risk for damaging winds and power outages is greatest to the southwest of Houston:

Several readers have asked about tornadoes. Yes, they’re possible within the rainbands of Beryl tonight and on Monday morning. However I expect their development to be fairly scattered, and the bigger threat for a majority of people will be winds directly related to Beryl’s circulation.

Some thoughts on power outages

I’ve spent a couple of hours today doing some digging to try and set some expectations for power outages tonight and later on Monday as the core of Beryl’s winds move into the greater Houston area. Our most recent tropical system with a major “wind” component was Hurricane Ike, a Category 2 storm that made landfall in 2008. It came ashore about 90 miles further east than where we expect Beryl, but it was a much larger and more powerful hurricane. Here is what Ike’s sustained winds looked like.

Ike knocked out power to 2.1 million CenterPoint Energy customers in Houston, and 10 days later the power remained out for about one-third of these customers. I want to be clear, I do not think Beryl will have this magnitude of an effect. Far from it, likely. But it’s useful to study the map of outages below and see where there were fewer problems (i.e. northwest Houston).

My back-of-the-envelope estimate here is that widespread power outages start to become more likely at sustained wind speeds of about 60 mph. The majority of Houston will probably less than this tonight, although such winds are likely in many areas of Brazoria, Fort Bend, and Matagorda counties. They are also possible west of Houston, in locations such as Katy.

My general expectation, therefore, is that power losses will be in the hundreds of thousands, and restorations in days; rather that losses above 1 million with a week or two of restoration. However that is a guess rather than a firm conviction, and given since so many people are understandably concerned about this issue.

Finally, I very much do not expect hurricane-force sustained winds tonight in any part of the Houston metro area apart from the immediate coast near Matagorda, and possibly locations such as Freeport or Lake Jackson. For what it’s worth, CenterPoint’s estimate for Category 1 winds is: “extensive damage to power lines and poles likely will result in power outages that could last a few to several days.”

The bottom line is that power outages will be a wait-and-see game. Good luck. Charge those phones now, my friends.

Let’s talk rainfall totals

We’ve seen some fairly widespread shower and thunderstorm activity today as Beryl’s outer rainbands have moved onshore. So far, it’s been fine. I expect to see additional storms this afternoon and evening, but it should be mostly manageable.

The main event should arrive at the coast a few hours before midnight, and push into Houston around midnight. Based on the latest modeling the “thickest” rain band will likely move through the city around 4 to 8 am, bringing intense rains that will quickly flood streets. Conditions should start to improve during the late morning hours. However I would expect to see additional rain showers later on Monday night and Tuesday due to trailing bands (which won’t be as intense). In any case, this is another good reason to stay home from this evening through Monday morning.

In terms of accumulations, it still looks like coastal areas face the highest risk, with totals of 5 to 10 inches likely, and accumulations further inland of perhaps 4 to 8 inches. What we’re most concerned about are more isolated areas that fall under the heaviest banding. These locations could see 10 or more inches of rainfall. It is impossible to predict precisely where these will set up, but the latest modeling is hinting at higher totals near Galveston Bay. We’ll see. We have a Stage 2 flood alert in place.

Storm surge

Peak storm surge levels, the combination of high tide and surge, should arrive on Monday morning the upper Texas coast. For Galveston Island and Galveston Bay, water levels are expected to be 4 to 6 feet above normal levels. Surge should be slightly higher in Matagorda Bay.

Final thoughts and plans for tonight

Beryl is on our doorstep, and its winds, rains, and waves will move into our area tonight. The key thing I’m watching over the next several hours is whether the storm starts intensifying, as a weaker Beryl will cause far fewer problems in Houston on Monday morning. As always, we will hope for the best and prepare for the worst. Please make plans to get home, or to a safe place this evening, and remain there through the morning hours on Monday.

Our next post will come around 10:30 pm CT tonight, and we’ll continue to post overnight and into Monday as this dynamic event develops.
