A FORECAST FIRST ALERT remains in effect Monday morning due to heavy rain and the potential for flooding. However, the threat of more rain and flooding is starting to wane.

Water rushed through Niagara Cave in Harmony, causing flooding and limited accessibility. Cave manager describes it as one of the top five worst floods.

The flood watch, which covers Olmsted, Winona, Mower, Dodge, Wabasha, and Fillmore counties, will be in effect from 10 p.m.
