First this message from the GRR NWS: ” I just got this from Jim Maczko, our Warning Coordination Meteorologist: Based on photographic evidence, radar data, video and media, Emergency damage assessments – damage caused by the storm on April 12th in Muskegon, Newaygo, Kent (other counties impacted by the same storm) was the result of straight-line wind damage equivalent to EF-0 on the Wind Damage Scale. We estimate from witness reports we have seen/heard, the strongest wind lasted between 3 and 5 minutes and peaked at an estimated 75-85 mph for a large portion of that 3-5 minutes. Damage seen throughout the path of this storm is consistent with what is typically seen from winds gusting to 75 to 85 mph for that long a period of time.”
