RECORD SOUTHERN WISCONSIN RAINS and FLOODING AGAIN

Prof. John Young, Wisconsin State Climatology Office Director
Dr. Edward Hopkins, Climatologist

10 June 2008 updated on 5 August 2008

A slow-moving weather system on the weekend of 7-8 June 2008 brought torrential rain to sections of southern Wisconsin as numerous thunderstorms developed across the region.  Rainfall totals over the weekend ranged between  two and ten inches over many locations that had received heavy winter snow and heavy rain last summer.  The recent rain caused some rivers to reach record crests, resulting in flooding and mudslides.  Several dams broke because of the rise in water levels in the reservoirs behind the dams.

See precipitation maps for south central and southeastern Wisconsin from the Milwaukee/Sullivan National Weather Service (NWS) Office and additional flood information for counties in western and central Wisconsin from the La Crosse NWS Office.  This office has a radar loop and storm damage information.  Additional information along with satellite imagery are available from CIMSS at UW-Madison. Current river observations and precipitation maps for previous days are available from the NWS Advanced Hydrologic Prediction Service for:
