freezes and winter cold snaps
Ohio freeze events combine lake-effect snow, ice, wind, and older housing stock where pipes often run through unconditioned spaces.
tornadoes
Ohio tornadoes are often part of fast-moving spring and summer systems, and the same storms can bring hail, roof damage, and power outages.
straight-line wind storms
Ohio windstorms include derechos, lake-enhanced lows, and fast frontal lines that damage roof edges, gutters, trees, and service masts.
