The heavy rain that led to dangerous flooding across Texas on Wednesday will expand over the lower Mississippi and Ohio valleys through tonight. Similar to Wednesday, any flooding that ensues will endanger lives.
Today's torrential rain will stretch from south-central Texas to the lower Mississippi River. This includes San Antonio, Houston, Alexandria, La., Little Rock and Springfield, Mo. The rain will then drench more of the lower Mississippi and Ohio valleys tonight.
Moisture from the remains of once-Hurricane Rick and the Gulf of Mexico will cause the rain to fall heavily. Flooding could quickly result in low-lying and poor drainage areas, as well as along small streams.
The threat for flooding will be greatest from San Antonio to Indianapolis. Through tonight, between 2 to 4 inches of rain is expected to soak this zone. Locally higher amounts are possible.
The flooding could force officials to close portions of area roads. I-20, I-40, I-45 and I-55 may become affected.
Even where flooding does not occur, motorists should use caution. Downpours will reduce visibility, while water ponding on highways and interstates could cause some vehicles to hydroplane. Airline passengers should also prepare for delays.
In addition to the flood threat, some thunderstorms across eastern Texas and the lower Mississippi Valley may turn severe. The Severe Weather Center has more information. The South and East Regional News stories discuss where the wet weather will eventually spread to.
