High Swim Risk Today

A Flood Watch is in effect from 1 AM to 1 PM CDT Saturday for portions of south central Wisconsin. Widespread heavy rainfall of 1 to 3 inches is forecast from tonight through Saturday morning across southern Wisconsin. Locally higher amounts are possible, especially where multiple rounds of storms move over the same areas. The better chances for this would be in the Flood Watch area, though there is some uncertainty with the exact location of the heaviest rainfall amounts. Rainfall rates up to 1 inch per hour are expected from storms. There is a risk for urban and small stream flooding, rises on area rivers and some flash flooding, especially in the Flood Watch area. Additional rounds of showers and storms may occur Saturday afternoon through Sunday, especially along and south of Highway 18 and Interstate 94. This may cause additional flooding. Stay updated on the forecast, and prepare for the heavy rain. "Turn Around, Don't Drown" if encountering any flooded roads.

Here is a graphic showing a table of rain chances for several locations across southern Wisconsin through Sunday evening. The heaviest rain is expected to fall overnight tonight into Saturday morning, with 1 to 3 inches of rainfall forecast and locally higher amounts possible. On and off showers and storms may continue Saturday afternoon into Sunday, which may bring additional flooding potential. The better chances for this would be along and south of Highway 18 and Interstate 94.
