ATL: BETA - Remnants - Discussion

[Portastorm]

With almost a half inch of rain since midnight, the Austin area has recorded the highest rainfall total from an Atlantic tropical system since Hurricane Harvey in 2017.

Thank you, Beta!

Clear Lake getting some training right now. 1.5 “ in the last hour. Ponding on the roads but it doesn’t take much for that, terrible drainage.

Not going to complain about the rainfall, we’ve missed most of the storms that hit Houston this summer.

[SoupBone]

Still nothing NW of Harris. No wind, no rain since last night. I guess we'll see once this heads more north if we see some of those bands.

Of course, as I'm typing this it starts sprinkling!

[Hurricane Mike]

The only hope is that maybe because Beta has so much dry air around it that maybe the rainfall won't be as high as it could be with other slow moving storms.

Assuming Beta remains intact, it will be the sixth TS or stronger landfall in the Gulf this year. The amount of activity in the Gulf has been ridiculous in 2020 — 6 named storms, 4 hurricanes, and 1 major that made landfall at peak intensity.

Closing in on 2.5" here in Richmond. Rain rates are picking up as I type this and looks like it is going to continue over the next several hours. HRRR running shows a slight lull in activity and then really ramps it up later this evening. Time will tell..

[Craters]

That feeder band just south of Houston dumped on us for an hour or maybe a little more. Got 2.7" out of it. In a break now, but it looks like more will be coming a little later.

Looks like landfall between Matagorda and Port O’Connor will be coming shortly.

[funster]

Beta's rainfall impact bigger than anticipated? 6 inches possible in areas through 8 pm.

I am holed up in a hotel room in Houston near the galleria. I drove in from Cut Off this morning because I have dr. appts tomorrow and
wednesday at MD Anderson. I had steady but very light rain from Cut Off to Lake Charles then no rain and dry roads from Lake Charles all the way into east Houston. Here it is currently light rain and about 70 degrees. No wind is even noticiable as the trees are barely moving.
I will update later with conditions.

The system that eventually became Fay also started in the Gulf. Doesn't really count, but it's still interesting.

So is that a record for the Gulf?

We had more rain than anything Beta dropped yesterday here in SW FL. Just watched local mets talking about how much rain. More than 4", I believe.

If you looked at the cloud movement, it's like we had a cyclonic circulation system come across the state from east to west. You could see it in the clouds! And then dropped immense amounts of rain yesterday and last night. So much so that a special weather statement came out noting flooding in the Peace River and points north.

Not trying to derail the Beta thread, but just pointing out how much MORE rain we had compared to an actual tropical system (who was supposed to drop plenty of precip, but apparently was unable to do so). At first I thought it was training from Beta, but it's completely dissipated now and it didn't seem to come from that direction, so I don't think it was associated with Beta. Not sure where it came from or where it went, but the rain we had yesterday was beyond ANYTHING we've had recently....even during any TS, such as Laura as she passed by us to the south/west.

Yes, that was a separate naked swirl which dropped out of the front that absorbed Sally (this wasn’t Sally though). It moved into the Gulf and apparently dissipated.

Decent rains coming onshore.

Lots of dry slot but Galveston has been stuck in a squall band off and on today.
Houston radar is an easy place to get the forecast, still some central circulation and NHC keeping surface pressure at 999mb with a few tropical storm gusts probably in the squalls.

GFS tracks the remnants NW over the gulf for almost 90 hours, but there is a lot of dry air just to the west. A small core could regenerate even if the NHC downgrades to a TD. We have seen systems with broad shallow pressure gradients just spin around harmlessly with lots of dry slots in a dry environment but squall bands can still cause local flooding if Beta persists.

[SoupBone]

I'm up to 1" of rain over the last 2 days now, but it's stopped for now.

[cheezyWXguy]

Lol I think this is the most central banding features I’ve seen it exhibit its entire life

[galvbay]

North side of Galveston Bay here...
1.5” rain last 48 hours...41mph gust and temps mid 70’s.
