Heavy Rains Over the Western Twin Cities:
September 3-4, 2005
A slow moving warm front spawned waves of thunderstorms over central and east central Minnesota
over Labor Day Weekend. The first wave began with lighter thunderstorms during the
afternoon of Saturday, September 3rd. Later in the evening and during the overnight
hours a line of heavy thunderstorms developed in a "training" pattern over the western
Twin Cities metropolitan area and moved south. People had difficulty sleeping with the
nearly constant rumbles of thunder all night long. When dawn came on Sunday, September
4th the rains totaled a half-foot in a few spots in the south west metro. The heaviest
rains fell in a very narrow band following I-94 from Alexandria and then turned to the
south along I-35 across the Twin Cities.
The most rain reported was 6.62 inches near Elko in New Market. 6.17 inches was reported in
nearby Cedar Lake Township. 5.66 inches was reported 2 miles southwest of the downtown
Chanhassen. The National Weather Service picked up 5.55 inches. The heavy rains caused
street flooding in low lying areas. Some roads were blocked by water for a brief time.
Water was up to the bumpers of cars in a parking lot in Excelsior. Other cities that
experienced street flooding were Shakopee, Chanhassen, Eden Prairie and Brooklyn Park.
A bluff slump happened along Highway 101 in Chanhassen but didn't impact the road. The
water seemed to recede quite quickly. Police also blocked off some streets in Sauk Center
due to street flooding.
large hail and damaging thunderstorm winds also accompanied the storms. Numerous reports
of hail were reported across the western Metro area. Golf-ball sized hail was reported
near Hutchinson and parts of Brooklyn Park. Lightning caused damage to three houses in
Minnetrista, Eden Prairie and Mound. Winds damaged hangars at the airport in Faribault.
The State Climatology Office thanks the Soil and Water Conservation Districts, the National Weather Service, and
all of the diligent volunteer precipitation observers who make analyses of these events possible.
Radar imagery from the Chanhassen National Weather Service depicts the storm rainfall total.
Listed below are National Weather Service Statements about the heavy rain and severe storms.
