Flooding and severe storms

Severe storms and flooding are expected to continue from the Rockies to the Midwest.  On Wednesday, flash flooding was reported from Iowa to Missouri where more than 8 inches of rain fell in a short period of time.  In Utah, severe storms brought wind gusts up to 77 mph, while some in Missouri saw hail as big as tennis balls. On Thursday, severe weather is expected from Colorado all the way to Georgia, where damaging winds and huge hail will be the biggest threat, but an isolated tornado cannot be ruled out.

Some of the severe weather will move into the Northeast late Thursday night into Friday.  On Friday, severe weather is possible from Pennsylvania through New York and into New England with damaging winds and large hail being the biggest threat.

Flood alerts have been issued for 11 states from Montana to Alabama, where slow-moving storms could bring 3 to 5 inches of rain in a short period of time and could produce flash flooding.
