I think we are ok. It has not even come close to the house. Oh and I hear kids playing the water. Lightning, thunder and wind...kids are playing in it. Lovely.

Yikes... I hope you got them in. There will be plenty of time to play in the water after the lightning has passed. Kids are so fearless.

No, not mine. My two kids are black cats and they are asleep. Neighbor kids.

Ohhh, ok. Well, I hope their parents get them in. I know I didn't worry about being struck by lightning when I was a kid, but it sure does happen. The water will be there later. I hope they get inside.

Call me a worry wart.

RUC/SFCOA GUIDANCE SUGGESTS THESE STORMS
ARE OCCURRING WITHIN A ZONE OF STRONG LOW LVL WAA...WHICH IS
SUPPORTED BY RECENT SURFACE PRESSURE FALLS /2-4 MB PER 2 HRS/ OVER
THE REGION.

I thought my ears were popping a lot. It's like night here(Baytown), and starting to see water in places I have never seen,

[srainhoutx]

Another Update from Jeff Lindner...

Significant flash flood event in progress over metro Harris County into Fort Bend and Wharton counties. Numerous street as completely impassable across Harris County. Channels continue to respond with a few nearly bankfull. Rainfall rates of 3-4" per hour will be moving into SE Harris in the next hour with totals now over Fort Bend and central/SW Harris nearly 4.0 inches. Large slow moving MCS painfully slowly moving ESE...will take at least another 1-2 hours to clear the county.

We went out to lunch and ran some errands. The rain is finally slackening off here. We had some crazy heavy rain for a couple of hours. There has been some minor street flooding around but nothing too major up here.
