Thus far, Barry has been virtually a complete non-event here in the Houston area. We have had a few showers and some nice sunrises and sunsets but not much else. We may begin to see a bit more activity today as Barry pulls out of the Southern U.S. and a slightly more complex pattern overhead allows storms to develop.

Rest of today

Tremendous bands of heavy rain and thunderstorms have been occurring all morning — in the Gulf of Mexico. Radar estimates 10 inches or more has fallen way out over the open Gulf, thankfully.

That area of rain will probably begin to dissipate today and new showers and storms should begin to fire up this afternoon, especially along or southeast of US-59. Weather modeling still disagrees on exactly how this will play out, but in general, scattered showers and storms should continue off and on in that general area: Call it southern Fort Bend, southeast Harris, Brazoria, Galveston, and Chambers Counties east to Port Arthur. Rains should be manageable in most cases, but we will want to keep tabs to see if any higher rain rates can get going. If that happens, some localized street flooding would be possible. Nothing to worry over, but something to monitor through tonight.

Overnight and Monday

Additional showers and storms may continue into tonight or Monday in those same general areas mentioned above. Again, localized heavy rain will be possible. How much rain in all when this ends?

I would expect an average of 1 to 3 inches south and east of Houston, with an inch or less average north and west of Houston. Some higher and lower amounts are both possible in those areas. We will watch this through the evening and update you in the unlikely event it is needed.

For those wondering how Louisiana is faring, things have been about as good as can be hoped for so far. Flooding is ongoing in spots, but severe, widespread devastating flooding has not materialized at this point. As heavy rains continue on saturated grounds, however, some problems could begin getting more troublesome. As of this writing, one significant band of heavy rain was aimed at the Baton Rouge area and another at New Orleans (which has fared fine so far). Flooding problems will worsen south of New Orleans unfortunately, in areas that have been relatively hard hit. If anyone cares to follow details on the event, I did create a list on Twitter with local Louisiana & Mississippi meteorologists, national tropical experts, and local government agencies and media.

Quick overview: Hurricane (now Tropical Storm) Barry made landfall near Intracoastal City, Louisiana this afternoon and is now slowly marching inland over Louisiana. While significant impacts are occurring from central Louisiana through coastal Alabama, we just have a few gusty showers for now in Texas. A more organized area of coastal rain may develop tomorrow and Monday, but details are still somewhat uncertain on exactly how much rain will fall. Either way, we do not expect significant problems at this time, and there are no further tropical concerns to speak of.

Tropical Storm Barry & Houston’s outlook

Barry is moving inland over Louisiana this evening, spinning just west of Lafayette.

Barry will continue a slow drift to the north-northwest and eventually north as we go through the night. All those clouds offshore indicates moisture, all of which will get thrust onshore into Louisiana tonight and tomorrow. Significant rains that have so far been worst in Alabama will begin to cause issues in Louisiana and Mississippi.

Maximum sustained winds are down to 65 mph, and a slow weakening will continue. Notice just a few bands of clouds on the west side of Barry heading into Texas. We’ve got some of the outer bands moving through Houston this evening. At times tonight, you can expect showers and some gusty thunderstorms, with winds perhaps of 20 to 25 mph, but not much worse.

No significant rains or impacts will occur tonight. Tomorrow should start off fair, with no issues expected. A few showers and storms will become possible from mid-morning on. Eventually that could congeal into an organized, slow moving band of heavier rain and storms south and east of Houston, primarily along the coast or just a few miles inland. As such, the Weather Prediction Center has our area is a marginal to slight risk of excessive rain tomorrow.

We are not concerned about significant, widespread flooding tomorrow, but we do think that areas south and east of Houston, primarily areas of southern Brazoria County through Galveston County and up the coast toward Port Arthur stand the best chance of seeing a slow moving, “training” band of showers and storms. While this is not a guarantee, if this were to occur, we could see some mostly minor street flooding in places like Galveston or Lake Jackson tomorrow afternoon or evening. Just something to be on the lookout for right now, and we will update you tomorrow on what expectations look like. In general, rain amounts south and east of Houston will be 1 to 2 inches on average, with higher amounts possible. From Houston to the north and west, some places may see up to an inch or so, and others may see nothing at all.

So if you have outdoor plans in Houston or north and west, you can probably go forward with them, but you may be briefly interrupted by some showers. South and east of Houston and at the beach, consider a backup plan in the afternoon in case the steady rain spoils those plans.

Lastly, there have been a lot of rumors and banter and questions about this storm changing course or that thing 3,000 miles out in the Atlantic becoming a threat. That’s just not true. No reliable modeling shows the thing in the Atlantic even surviving into the Caribbean, let alone all the way to Texas. And the track of Barry has been pretty much set in stone since yesterday or even Thursday, truthfully. So you have absolutely nothing to worry over right now. More tomorrow.

Tropical Storm Barry is flirting with hurricane intensity this morning south of Morgan City, LA. Maximum sustained winds are 70 mph, and it’s possible Barry could cross the finish line as a hurricane. Landfall is expected somewhere on the west side of Vermilion Bay, LA this afternoon.

Moving forward, Barry will slowly move inland over Louisiana, and all those bright clouds that indicate thunderstorms are going to come ashore in Louisiana. It’s been mostly nuisance rain there so far, but it will escalate significant later today or tonight. Storm surge flooding is an ongoing issue across much of eastern Louisiana.

We will continue to see these problems through the day, and then the rainfall will begin to cause problems tonight.

How much rain?

Well, according to the NWS Weather Prediction Center, most of eastern Louisiana should see four inches or more of rainfall, with the bullseye between Lafayette and New Orleans of 10 to 15 inches. This bullseye may end up near the Baton Rouge area.

This serves as a nice breakpoint for us to shift gears and talk about Texas. That official forecast shows 1 to 2 inches through Monday afternoon between Galveston and Beaumont, with lesser amounts north and west of there. Let’s break things down a bit.

If you’re a more weather savvy Houstonian, you’ve spent a chunk of the day with a satellite loop of Tropical Storm Barry open in a browser tab, checking it periodically and perhaps feeling a bit uneasy. And that’s completely understandable. The good news is this: Despite what your eyes are telling you, everything, forecast-wise, is still on track, and Barry is expected to move into Louisiana tonight and tomorrow.

Here’s what I’m talking about:

From the above satellite image, you can see the adorable cinnamon bun-esque swirl south of the Louisiana coast today that now appears to be moving back southwest. Believe it or not, that is not center of Tropical Storm Barry. That is what we call a “mesovortex” swirling around the broader center that is to the south and will gradually turn to the northwest tonight. As Barry organizes a little bit healthier tonight, you’ll probably begin to see a slightly more traditional satellite presentation try to evolve. Wind shear will continue to limit how well organized Barry can become, but it would seem likelier than not that Barry becomes a hurricane tonight before making landfall tomorrow near Vermilion Bay. The turn will happen, we just need to be patient.

Impacts are mostly unchanged, with major rains expected to slog inland tonight and tomorrow over Louisiana and Mississippi. Heavy rain is likely between Lafayette and New Orleans, though the more recent rainfall forecast have backed down a bit in NOLA, which is good there, but a lot of rain is going to fall upstream over the Mississippi. Maximum totals should be 15 to 20 inches, probably not far from Baton Rouge.

This morning I discussed the possibility of heavier rain potentially near Galveston or the Bay Area. Basically, we expect some type of inflow band, or an area of converging winds to setup near the coast tomorrow night and much of Sunday. If that happens, locally heavy rain will be possible, particularly along the immediate coast. The rainfall forecast above shows about 1 to 2 inches potentially near Galveston, with less as you come inland. We will have to refine this tomorrow a bit, just in case the heavier rains stay offshore or to our east, or alternatively look heavier over Galveston. For now, in Galveston, expect a forecast of persistent rains on Saturday night and Sunday with occasional showers or clouds inland from there. Saturday is probably a satisfactory beach day, but Sunday may be a loss. We will reassess how things look in the morning and offer you another update then.
