Jim is correct, this weather pattern is moving south to north and headed up to Dallas and generally all over the state. they claim the worst of it is over now. More rain Saturday and Sunday. It is fed by the circulation (now a low pressure) resulting from hurricane Alex. Lows and hurricanes rotate counter clockwise and the low is over Mexico now. The rains are being feed as the moisture is dragged from the gulf.
The I-10 flooding was on the main lanes, just east of down town. As you come into Houston, you have the choice of taking Beltway 8 which becomes the Sam Houston Tollway (take it to the north) but the tolls will be 3 or 5 plazas to get back to I-10 on the west side. Or take Loop 610 to the north and all the way to I-10 on the west side.
Once the rain stops, the water will go down pretty quickly. The problem on the east side was the pumps at an under pass were not running to relieve the water.
You should be good to go to come straight through on I-10 this weekend.
