Much of southeast Michigan faced thunderstorms Sunday but the threat passed by late night with only an isolated storm possible as a weak cold front crossed the state, the National Weather Service said. 

A storm moved east through portions of Wayne, Oakland, Macomb and Monroe counties during the day, meteorologists said, and produced wind gusts higher than 50 mph, which could knock down tree limbs and blow around unsecured objects.

Strong storms also swept through portions of Livingston, Genesee, Sanilac, St. Clair and Lapeer counties, the weather service said. 

Caseville in Huron County reported winds of 56 mph, Grand Blanc in Genesee County reported downed power lines, and Sanford in Midland County and Owosso in Shiawassee County reported downed lines. One-inch hail was reported in Argentine in Genesee County.

Marine warnings throughout southeast Michigan also are in effect. 

The weather service issued a special marine warning for watercraft near the shore and on open water from Port Salinac to Port Huron until 8 p.m.

The storm was expected to bring wind gusts of 34 knots or higher and small hail, which could damage small craft and create higher winds and waves. The weather service recommended moving to safe harbor until the hazardous weather passed.

DTE Energy reported 1,454 customers without power at 11 p.m. with 57 crews in the field. Initially, small clusters could be found on the outage map throughout Detroit, Redford Township, Westland and east Dearborn. Larger clusters were found near Whitmore Lake and Brighton.

Consumers Energy initially had 1,755 consumers affected, with a large cluster near Arenac, and 68 crews working on restoration. By 11 p.m., that number was down to 456 customers affected and 51 crews in the field.

A special marine warning was issued through 8:45 p.m. Sunday on Lake St. Clair, Lake Erie, the Detroit River and Lake St. Clair. Storms threaten to bring winds higher than 40 knots and pea-size hail. Boaters should find safe harbor, the weather service said.
