Well maybe Jasons was on to something earlier when he said we may not be out of the woods yet. HRR looks to develop some pretty heavy storms tomorrow across other areas of SETX too.

San Antonio is getting pounded tonight. They are not as equipped to handle so much rain in such a short period of time. So we've had the Houston, Beaumont, and San Antonio metro areas impacted by Imelda. Remarkable for a low-end TS. It illustrates that you don't need a hurricane or a 'major storm' to cause flooding issues.

I harp on this quite frequently on S2K. The number one cause of death from tropical cyclones is not wind damage or storm surge. It is inland flooding.

Sorry for the multiple posts, but I was away this evening and I'm just now catching-up.

The remnants of Imelda are definitely on the move. She's now moving up into far NE Texas, and approaching Oklahoma. This is good news is that it did not stall and take the hard left turn towards towards Groesbeck/Mexia like the WPC was forecasting yesterday. I do see that the inflow has shifted from the SW that was apparent earlier today to a more traditional SE, onshore flow. As the center pulls off to the north, the chances of additional banding and convergence zones is going to decrease. I think we've finally turned the corner and the focus will now shift to what's in the cards for next week.

It has been rather dry in Texas lately.

Droughts tend to end in flooding.

I just did a quick model check and I don’t see anything major left. I’m feeling much better about things drying out now. Always a chance some storms fire tomorrow but nothing major. A cousin sent this over:

Per The Weather Channel, Imelda is the #5 wettest system to hit the contiguous United States. Harvey is still #1
