Southeast Michigan — the Metro Detroit region — combines the highest population density in the state with significant severe-weather exposure. Wayne, Oakland, Macomb, Washtenaw, Livingston, and surrounding counties face frequent severe thunderstorms, occasional tornadoes (most notably in Washtenaw and Lenawee), winter storms that can paralyze freeways, and growing concern about urban flash flooding as drainage infrastructure ages. Lakeshore flooding affects Wayne, Macomb, Monroe, and St. Clair counties along Lakes Erie, St. Clair, and Huron.

Monroe County is served by NWS Detroit/Pontiac, headquartered in White Lake, MI, which issues all official severe-weather watches, warnings, and advisories for the county under the SAME geographic code MIC115. Alerts shown above come directly from the National Weather Service public-alerts feed and update within seconds of issuance.

When a Tornado Warning is issued

A Tornado Warning means a tornado has been sighted or indicated by radar in Monroe County or an adjacent area — take shelter immediately. Move to the lowest floor of a sturdy building, away from windows, and into an interior room (basement, bathroom, or closet). Mobile homes and vehicles are not safe; if you're in either, leave for a sturdy structure if you can do so safely. Tornado Warnings are typically issued for 30–60 minutes; stay sheltered until the warning expires or NWS Detroit/Pontiac confirms the threat has passed. Monroe County residents should monitor a NOAA Weather Radio (programmed for SAME code MIC115), local TV, or this page.

When a Flood Warning is issued

A Flood Warning means flooding is occurring or imminent in Monroe County. Do not drive through flooded roads — most flood-related deaths in Michigan occur in vehicles attempting to cross water. If you live in a low-lying area near Monroe or along major waterways in the county, monitor official water-level reports from the U.S. Geological Survey and prepare to move to higher ground. Flash Flood Warnings carry the same urgency on a shorter time horizon — typically less than an hour to act.

When a Winter Storm Warning is issued

Winter Storm Warnings in Monroe County indicate hazardous winter weather (heavy snow, freezing rain, sleet, or blizzard conditions) is occurring or imminent. Avoid travel; if you must drive, carry an emergency kit (blankets, food, water, flashlight, charged phone). Heating-source safety is critical: never run generators or grills indoors, and check carbon-monoxide detectors before relying on alternative heat sources.
