Monsoonal moisture will produce showers and thunderstorms with heavy rain over parts of the Southwest, Great Basin, and Central Rockies through Monday. Flash flooding is possible, especially in and around burn scars and in areas of steep terrain. Heat will persist across the Central U.S. early this week, spreading into the Ohio Valley and Mid-Atlantic later this week. Read More >
September 11th, 2019: High Winds Strike Greater Grand Rapids Area
|
|
| Radar loop from 4:00 to 9:30 PM 9/11/2019. Note the line of storms that went through Grand Rapids, Michigan, where the most concentrated damage was reported. |
During the afternoon and evening hours of September 11th, strong to severe storms moved across western Lower Michigan. A ~50 mile swath of damage occurred from Walker to Lake Odessa with uprooted and snapped trees and numerous power outages due to estimated 65 to 80 MPH winds. A more concentrated area of damage was found in Grand Rapids especially east of US-131, where wind gusts locally approached 100 mph. Along the entire swath, there was little evidence lofted debris which would be typical of tornadoes, though brief swirls likely occurred in the swath.
Earlier in the day, hail as large as ping pong balls (1.5" in diameter) and scattered wind damage was also reported, especially across Newaygo and Montcalm counties.
Finally, the storms provided much needed rainfall with swaths 1-2" across western Lower Michigan.
Swath of High Winds:
As a line of storms moved toward Grand Rapids, they intensified rapidly and produced a roughly 50 mile long swath of 65 to 80 mph winds from Marne to Sunfield. The north side of Grand Rapids was hit particularly hard where wind gusts likely approached 100 mph. The damage along the swath was immense, with trees snapped and uprooted and damage to buildings, especially in the Belknap Lookout neighborhood of north Grand Rapids.

| Radar reflectivity (left) and radial velocity at 7:54 PM as the line of severe storms moved through the Grand Rapids area. The black line denotes the swath of the most intense damage. Note the fine green line on the left image ahead of the line of storms showing the location of an outflow boundary--this was key to identifying the location of where the strongest winds would occur with this storm. |
Two NWS Damage Survey teams combed through the damage to determine what occurred. The damage survey process includes looking at the damage from the ground, talking to those who witnessed the storm, and reviewing radar data. Oftentimes, the determination between tornadic and non-tornadic winds is not trivial, which was certainly the case with this storm.
