Some flood warnings in effect; expect more thunderstorms on Tuesday

After a burst of thunderstorms to start the work week, Metro Detroit will get a brief break overnight before another round on Tuesday.

Flood warnings, however, were in effect until Tuesday morning in Gratiot, Ionia and Montcalm counties, where some roads were washed out, the weather service said.

The National Weather Service forecasts temperatures near 80 and a chance of showers and thunderstorms mainly after 5 a.m.

“The best shot (for storms) is during the morning hours” — likely after 8 a.m., meteorologist Phil Kurimski said. New rainfall amounts between a quarter and a half-inch are possible the weather service.

That follows rounds of storms Monday that brought heavy rain in spots. In a roughly 12-hour span, more than an inch fell across parts of Shiawassee and Genesee counties, according to the weather service. Other areas south, including Detroit Metro Airport, reported less than 0.25 inches by early evening, Kurimski said.

DTE Energy reported scattered outages across the region. At 6:30 p.m., an online map showed at least 1,500 outages west of Ypsilanti Township and pockets of less than 500 near Troy, Farmington, Plymouth, Taylor, River Rouge and Lincoln Park. Most were expected to be restored tonight, spokesman Scott Simons said.

Consumers Energy’s website reported more than 1,000 outages on the state’s west side.

Earlier, a severe thunderstorm packing winds estimated at more than 80 mph spawned a tornado, injured at least six people and caused damage to homes.

The storm intensified late Sunday over Kentwood, just south of Grand Rapids.

The tornado’s winds reached 100-110 miles per hour , weather service forecaster Brian Meade said Monday. The impact was serious but limited in area, he said.

“It’s not extensive damage, but there was some heavy damage within it,” Meade said.

The tornado knocked down trees and power lines, ripped the roofs of a number of houses and sent two people to hospitals for treatment after their homes collapsed, Kentwood Mayor Stephen Kepley said in a statement. Many roads remained impassible Monday afternoon because of fallen trees.

The American Red Cross opened a shelter about 1 a.m. Monday at a Kentwood recreation center, and about 60 people took shelter overnight, said Kent County emergency management coordinator Jack Stewart. He said about 20 people were still there Monday afternoon.

In all, six people were hurt, with none of the injuries appearing life-threatening, Stewart said.
