MICHIGAN — A significant and multi-hazard weather event is ongoing across Michigan from late Monday April 13 into early Tuesday April 14, with the highest severe threat zone active now through roughly 5 to 6 a.m. bringing damaging winds up to 70 mph and large hail up to 1.75 inches in diameter as primary concerns, while a separate zone faces flash flooding concerns with 1 to 3 inches of rainfall expected overnight and rivers and dams already nearing their limits across the region.
Red Zone Active Now Through 6 AM With 70 MPH Winds and 1.75 Inch Hail as Primary Threats
The highest severe risk zone, marked in red on the overnight outlook map and covering portions of northern and central Michigan including areas around Traverse City, Ludington, and Saginaw, is currently active and will remain the primary area of concern through roughly 5 to 6 a.m. Tuesday morning.
Forecasters identify damaging winds up to 70 mph and large hail up to 1.75 inches in diameter as the two primary hazards within this zone during the overnight window. Tornado risk is characterized as very low tonight, providing some reassurance, but the wind and hail threats alone represent a serious and ongoing severe weather situation for communities within the red zone through the early morning hours.
Yellow Zone Carries Low Severe Risk for Southern Lower Michigan After 4 AM
Southern lower Michigan, including communities around Grand Rapids, Lansing, Kalamazoo, Detroit, and extending into northern Indiana and Ohio, falls within the yellow zone on the overnight outlook. Forecasters indicate that not much severe activity is expected for southern areas until closer to sunrise.
By the time storms reach southern lower Michigan, guidance suggests they will be considerably weaker in nature, resulting in a low overall severe risk for this zone. However, forecasters note that if storms do become severe in the yellow zone, damaging winds and large hail remain the primary concerns. Tornado risk in the yellow zone is also characterized as very low.
Green Zone Faces Flash Flooding Risk With 1 to 3 Inches of Rain and Isolated 3 Inch Totals
A separate but equally serious concern is developing across the green circle zone covering the northern portions of Michigan’s Lower Peninsula and parts of the Upper Peninsula around Petoskey, Alpena, and Escanaba. This area is expected to receive a swath of 1 to 2 inches of additional rainfall tonight, with isolated areas potentially seeing up to 3 inches through Tuesday morning.
Flash flooding is identified as the main concern for this zone, along with renewed worries about rising river levels. Forecasters specifically note that many area rivers and some dams are already nearing their limits heading into tonight’s round of rain, meaning the additional rainfall will compound an already stressed hydrological situation across the affected area.
Tuesday Evening Severe Risk May Prove More Significant Than Tonight’s Ongoing Threat
While the current overnight severe weather situation demands immediate attention, forecasters are already flagging that Tuesday evening carries its own separate severe weather risk that may ultimately prove more significant than what is occurring tonight across Michigan.
Residents are urged to remain weather aware not only through the current overnight event but also as Tuesday progresses and the next round of potential severe weather approaches the region. Continued monitoring of local weather alerts and forecast updates throughout Tuesday will be essential as the week’s active weather pattern continues to develop.
