DETROIT (WWJ) – A massive storm system moved through metro Detroit overnight, leaving many area roads and freeways flooded.

A major backup was reported on northbound M-10 between Evergreen Road and Civic Center Drive, where a storm water pump failed amid a torrential downpour.

Reporting live from the scene, WWJ’s Ron Dewey said there’s about a foot of standing water on the freeway. Before 9 a.m., officials shut down the northbound side of the freeway. It’s unclear how long the closure will last.

Flooding is also causing issues on I-75 near the Southfield Freeway exit. Standing water has been reported on several area roads, especially those in low-lying areas.

Forecasters say the potential for flooding will increase Wednesday as rain continues to fall.

The system is moving from west to east, according to CBS 62 Chief Meteorologist Jim Madaus, and we can expect to see more storms into the evening.

“As we go through the day, we’ll see some sunshine heating up the atmosphere and then exploding storms possible later in the day,” Madaus said.
