Storms across northern Michigan Saturday caused wind damage and heavy rains - which in turn has also caused flooding.
Here are some reports from Saturday:
Two overturned trailers just NE of Big Rapids; trees, power lines down, roof in the road, and a shed destroyed in Barryton (Mecosta), a plane flipped over and a hangar destroyed at the Grant Airport (Newaygo); widespread wind damage in Isabella County-reports of uprooted and snapped trees, in Blanchard-a destroyed shed, a tree on a house, a camper flipped upside... down and pushed up against a house, and irrigation pivots flipped in fields; multiple roads flooding over in the Central Lower- including M-82 in Montcalm & Newaygo counties, M-66 and 9 Mile in Sylvan Twp in Osceola Co., and multiple roads flooding in S Mason Co.; tree uprooted and on a house in Ludington, Middlebranch River out of its banks near Manton (Osceola); and the Muskegon River is flooding portions of Big Rapids-including the Charter School and multiple roads are closed.
Here are some of the rainfall totals from a 24hr period ending early Saturday:
4mi WSW Fremont (Newaygo)-3.85", 2mi SE Hersey (Osceola)-3.48", Ludington (Mason)-3.46", 5mi WNW Weare (Oceana)-3.36", Roben-Hood Airport (Mecosta)-3.18", 5mi ESE Harrison (Clare) and Gladwin-2.78", Reed City (Osceola)-2.77", Wellston (Manistee)-2.42", Baldwin (Lake)-2.17", Ironton (Charlevoix)-2.14", Au Gres (Arenac) and West Branch (Ogemaw)-2.1", Manistee-2.04", 7mi NW Scottville (Mason)-1.94", Parkdale (Manistee)-1.93", Mt. Pleasant (Isabella)-1.67", Roscommon-1.5", East Tawas (Iosco)-1.43", Manton (Wexford)-1.31", Grayling (Crawford)-1.11", Jennings (Missaukee)-1.1", Benzonia (Benzie)-1.02", Lupton (Ogemaw)-1".
Based on radar data, video, photographs, and emergency damage assessments, the National Weather Service in Grand Rapids has concluded the damage is from straight line wind damage. It's estimated winds peaked at 75-85mph for 3-5 minutes, which is equivalent to EF-0 on the Wind Damage Scale - and the damage seen matches winds gusting that high for that length of time. Straight line winds are frequently responsible for wind damage associated with a thunderstorm. They differ from a tornado in that they're not rotating - debris from a tornado is strewn about in all different directions, damage from straight line winds (ex: trees) is laid out in almost parallel rows.
With more rain arriving Sunday evening, the L.P. could be picking up another 1-2" through Monday, and a flood watch remains in effect for all of the L.P. through Monday evening.
