The Grand Rapids National Weather Service has confirmed that damage in Kent County was from an EF1 tornado. They say: “*** 6 INJURED *** NWS STORM SURVEY CONFIRMED AN EF-1 TORNADO TOUCHED DOWN IN BYRON CENTER BEFORE MOVING INTO WYOMING AND THEN KENTWOOD BEFORE LIFTING. THE TORNADO HAD MAXIMUM WINDS OF 100 TO 110 MPH. THE PATH LENGTH WAS 6.25 MILES AND THE WIDTH WAS 300-400 YARDS.. Aerial view of storms damage from Adam Dabaja. There is a Flood Warning for the Pine River at Alma, where the river will rise to a couple inches above flood stage. There is a Flood Advisory for the Grand River at Ionia and the Maple River in Clinton County with the river will cause some minor flooding, but stay below flood stage. Rainfall: 4.90″ Alma, 4.82″ McBride (E. Montcalm Co.), 3.72″ Bellevue, 3.13″ Elsie (Clinton Co.), 3.00″ Howard City, 2.74″ Ionia, 2.60″ White Cloud, 2.31″ Grand Ledge, 2.30″ Entrican (Montcalm Co.), 2.00″ Mt. Pleasant, 1.90″ Lansing and DeWitt, 1.68″ Grand Rapids, 1.44″ Hastings. Hail was reported in Holland and Jenison. Wind gusts hit 45 mph at the Ford Airport in G.R. Here’s W. Michigan storm reports and rainfall totals. As of 7:45 pm – 1,029 in Kent Co. without power, though a scheduled outage will bump that up close to 3500 for a couple hours this evening. The path of this tornado is similar to a tornado that occurred on April 21, 1967. That was an F-3 and destroyed 65 buildings.
Kyle Underwood viewed storm damage and called it a tornado, an EF1. There were at least 6 injuries and the damage path goes on for at least 6.25 miles from S. Wyoming into Kentwood and far south G.R. With these events it’s very hard to tell between tornado and thunderstorm downburst wind damage. If the tornado had winds of 70 mph and a forward speed of 20 mph, you’d get a resultant 90 mph on the right side of the tornado and 50 mph (and hence little damage) on the north side of the tornado…so the damage would be similar with most of the debris falling in one direction. The National Weather Service is doing a more complete damage survey and make the ultimate call. Here’s more on the Sunday night storms from the GRR NWS. In their summary, they say: “In the reflectivity data, in the next-to-last frame, an area of higher reflectivity appears over Kentwood, likely indicative of lofted debris. The “lofted debris” is an indication of a tornado. Here’s a list of roads closed as they clean up debris from the storm. Here’s photos of the storm and storm damage. Lower Michigan is in the General Thunderstorm Outlook for this PM/Night, but not a Slight Risk Area. Here’s Grand Rapids Radar and Regional Radar.
Also, a strong 7.1 magnitude earthquake has hit Mexico and Guatamala. There are fatalities.
