Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

  DURING THE EVNING. ADDITIONAL RAIN OF AN INCH OR TWO WILL RUNOFF
  AND CAUSE FLOODING OF SMALL CREEKS AND STREAMS...HIGHWAYS...
  STREETS...UNDERPASSES AND DITCHES ALONG ROADS. THIS COULD ALSO
  LEAD TO ROAD WASH OUTS AND FLOODING OF NEARBY LOW AREAS.

WALKER...HACKENSACK...PILLAGER...PINE RIVER...AITKIN...
MCGREGOR...CARLTON...MOOSELAKE...DULUTH...AND FLOODWOOD. 

BE ESPECIALLY CAUTIOUS TONIGHT. IT IS HARDER TO RECOGNIZE THE 
DANGERS OF FLOODS AND FLASH FLOODS.

ABSOLUTELY DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER
COVERS THE ROADWAY. VEHICLES CAUGHT IN RISING WATER SHOULD BE
ABANDONED. MOVE TO HIGHER GROUND.
