Detroit, Michigan – Residents across southeast Michigan should prepare for a higher threat of severe thunderstorms Monday as forecasters warn that damaging winds, large hail, and localized flooding could impact the region from the afternoon into the overnight hours. While the exact timing remains uncertain, the entire area is now under a Slight Risk (Level 2 of 5) for severe weather.
According to the National Weather Service in Detroit/Pontiac, thunderstorms could begin developing as early as 10 a.m. Monday, but the greatest risk is expected between 2 p.m. Monday and 2 a.m. Tuesday, with storms exiting the region by 4 a.m. Tuesday. Forecasters say instability combined with strong winds aloft will create favorable conditions for severe thunderstorms.
The primary hazard is damaging wind gusts approaching 70 mph, with hail around 1 inch in diameter also possible. Localized flash flooding may develop where repeated heavy downpours occur, while the tornado threat remains low but is not zero.
Communities including Detroit, Ann Arbor, Pontiac, Flint, Monroe, Port Huron, Adrian, Jackson, Howell, and surrounding areas should closely monitor the latest forecasts. Travelers along I-75, I-94, I-96, M-59, and US-23 could encounter rapidly changing conditions during the afternoon and evening commute, including torrential rain, dangerous lightning, and sudden wind gusts capable of downing tree limbs.
Residents are encouraged to secure outdoor furniture and loose objects before storms arrive, charge electronic devices, and ensure Wireless Emergency Alerts are enabled on mobile phones. Have multiple ways to receive warnings, especially overnight when storms may continue after dark.
Additional watches and warnings are likely if confidence increases in the timing or intensity of Monday’s storms.
