The National Weather Service's La Crosse Office says strong to severe thunderstorms are expected today and tonight, with possible damaging winds, large hail, lightning, locally heavy rain and isolated tornadoes.
Winneshiek County Emergency Management Coordinator Sean Snyder says a line of thunderstorms which went through Winneshiek County Monday night did some damage then—especially in the Castalia area. Snyder says he's been in contact with the La Crosse NWS Office and they are beginning to investigate the damage done Monday night.
