Southwest Michigan — including Berrien, Cass, Van Buren, Allegan, Kent, Kalamazoo, and Ottawa — lies in the heart of the Midwest's tornado-prone corridor. The most severe and frequent tornadoes in Michigan history occur in this region, with peak activity from April through July. Lake Michigan moderates winter temperatures along the immediate shoreline but generates substantial lake-effect snow inland. Lakeshore flooding from sustained westerly winds is a known hazard for Berrien, Van Buren, and Ottawa counties.
Branch County is served by NWS Grand Rapids, headquartered in Grand Rapids, MI, which issues all official severe-weather watches, warnings, and advisories for the county under the SAME geographic code MIC023. Alerts shown above come directly from the National Weather Service public-alerts feed and update within seconds of issuance.
The U.S. EPA's Safe Drinking Water Information System lists 82 public water systems in Branch County with open health-based violations or recent enforcement activity.

Based on Branch County's southwest lower peninsula geography, residents and visitors should be prepared for these recurring weather threats:
A Tornado Warning means a tornado has been sighted or indicated by radar in Branch 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 Grand Rapids confirms the threat has passed. Branch County residents should monitor a NOAA Weather Radio (programmed for SAME code MIC023), local TV, or this page.
A Flood Warning means flooding is occurring or imminent in Branch 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 Coldwater 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.
Winter Storm Warnings in Branch 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.
