SHEPPARD
Flood Watch
National Weather Service La Crosse WI
441 AM CDT Fri Apr 17 2026
.Another round of storms is expected to impact the area this
afternoon and evening. Increased moisture across the area will allow
these storms to be efficient rainfall producers as they move
through. There is potential for repeated rounds of activity,
especially east of the Mississippi River, where significant rainfall
has already occurred this week. With soils already saturated and
plenty of ponding across southwest and central Wisconsin, any
additional rainfall will significantly increase the potential for
flash flooding or areal flooding.
