Heavy rainfall slows morning commute; storms could redevelop this afternoon

Author:

Strong storms with "torrential rainfall" and frequent lightning are affecting nearly the entire state for the morning commute, and thunderstorms could redevelop Tuesday afternoon, the National Weather Service says.

Excessive runoff could cause the ponding of water in urban areas, highways, streets and underpasses, as well as other low-lying spots, the National Weather Service says. Motorists are advised to avoid flooded roadways.

The heavy rainfall is already slowing the morning commute. Flooding was reported on Interstate 394 near Minneapolis, while

Flooded roadways were also reported on Highway 280 in Brainerd, Mpls/St. Paul Traffic tweeted.

Some power outages were also reported west of the Twin Cities, Xcel Energy's outage map shows.

Storms could redevelop

Thunderstorm activity will diminish later this morning, moving out of the metro area by lunchtime, the weather service notes. And then we have another hot and humid day on our hands, with afternoon temperatures expected to reach the upper 80s for most of the state.

But storms – including some that have the potential to be severe – could redevelop in the afternoon and evening as a cold front moves east across the state.

Expect much cooler, less humid air Wednesday, but with that there will be some gusty winds, KSTP says. Highs in the upper 70s to lower 80s are expected, the weather service says.
