Texas and plain states: floods, storms

Flash-flood watches and warnings were issued across seven states early Tuesday as an unprecedented downpour of torrential rain triggered “extremely dangerous and potentially life-threatening” conditions in Houston. 

More than 30 million Americans were told to brace for dangerous thunderstorms — including flooding, hail and possible tornadoes — as meteorologists warned the weather that has centered on Texas and Oklahoma since Saturday could expand to other areas. 

At least 12 people were still missing, eight people have been killed, and countless more evacuated amid the deluge that has inundated Texas and Oklahoma with record-breaking floods since Saturday. 

In Houston, more than 80,000 people were without power and the flood waters closed roads including Interstate 10 and Interstate 45. Houston was among 24 counties where Texas Gov. Greg Abbott declared a state of disaster on Monday.

Houston Intercontinental Airport smashed its all-time record for most rainfall in one day on Monday — its 4.34 inches almost doubling the previous milestone set in 1946.
