I have the center moving inland near the TX/MX border Monday then tracking slowly NE, bringing lots of rain to Texas.


Spread out or more localized impacts? We (Houston) can handle rain over time, it's been pretty dry lately, but not inches in a few hours as I'm sure you obviously know.

But the trend by the GFS is for the upper ridge to expand some northward. The Euro also shows the same.

A Central Texas coast landfall is what I would bet on right now somewhere between Corpus Christi and Matagorda Bay.

Where have you been man? You're usually a much more busy poster than you are this year. What are you thinking right now? Minimal Cat 1 into central Texas?

Sorry, I was busy with my friends back in Nola during Ida. Since then I have been taking a break and catching up on a lot of work :wink:
If it stays offshore like some Euro ensembles show and the latest GFS show there is a good chance of at least a Cat 1. IMO.
I will continue watching the trends over the next 24 hrs, you know how this part of the GOM gives us surprises.

Models always have a hard time with intensity very hard to predict how strong something will get several days in advance without a closed off low.

When these things pass the eye-test, they always come together quicker than models depict. Should have a depression within 24 hours

Someone earlier showed a ton of dry air in its way deep into Texas and into the Gulf of Mexico. Is that what keeps it in check? Can anyone post that again?

GFS is putting a foot of rain in Jefferson/Chambers CO’s TX. So Vidor, Beaumont, Port Arthur, Groves, Port Neches, Orange, Rose City and all those other towns near the TX/LA border. Not the most rain ever but everyone over that way knows the flooding dangers.

Only 102 hours so thru early Wednesday

The GEFS is quite a bit further west than the op.
