...NWS Damage Survey for 3/30/2025 Tornado Event...

.Overview...
A severe squall line of thunderstorms progressed through

(straight-line) wind damage, and in some cases brief 
tornadoes also occurred. This is the 12th tornado in the 
state of Michigan that NWS meteorologists have been able to 
confirm from this storm complex, based on analysis of radar

Survey Summary:
A surge of thunderstorm wind occurred in the Alton area in 
Vergennes Twp, near 2 Mile Rd and Alden Nash Ave, to 3 Mile Rd 
west of Lincoln Lake Ave, where scattered tree damage was found.
On the northwestern flank of this wind surge, damage was more 
evident of a tornado which developed southeast of Murray Lake, 
near 4 Mile Rd and Byrne Ave. A farm outbuilding collapsed and 
other buildings lost roofing material. Sheet metal was carried 
0.4 miles to the north. The tornado downed about 25 trees in 
Grattan Twp, along 5 Mile Rd west of Lincoln Lake Ave. About a 
dozen more trees were down on the east side of Lincoln Lake Rd 
between 5 Mile and 6 Mile Rd. The path ended northeast of 6 Mile 
Rd and Lincoln Lake Ave. The tornado was moving with the storm's 
gust front at a speed of 60 MPH. There was a gap in concentrated 
damage beyond this tornado's end point, though radar data 
suggests the broadening wind surge associated with this tornado 
combined with another small wind surge which consolidated into 
the previously confirmed tornado west of Belding about 4 minutes 
later.
