A stationary line of storms dropped heavy rain, with as much as 8 to 10 inches in some areas, paralyzing traffic and sending some cars floating down streets.Record-setting heavy rain caused widespread flash flooding across the Twin Cities on Wednesday night — and there's more wet weather to come.
Up to 6 inches of rain fell in some northern suburbs in the space of about two hours Wednesday evening, and a flash-flood warning remained in effect for a narrow swath of the Twin Cities — from Greenfield to Hugo and south to Brooklyn Park, Blaine and Crystal — until 4 a.m. Thursday, according to the National Weather Service in Chanhassen.
One observer reported 9.67 inches of rain on the night recorded by a backyard weather station in Maple Grove. And in Waseca,
8.2 inches of rain fell in six hours, the Weather Service said, leading to a flash-flood warning there and in Owatonna until 6 a.m.
Among the roads closed early Thursday by water,
Interstate 90 was shut down between Exit 175 and Exit 179 near Austin, the Minnesota Department of Transportation said.
A flash-flood watch covered a broad area from north of the metro area southeast to the Iowa border and eastward into Wisconsin.
