La Crosse WI, (KROC-AM News) - About three-fourths of Minnesota is covered by Wind Chill Warnings.

The Rochester area is included in a warning that will be in effect until noon on Sunday. Forecasters say wind chill readings are predicted to hit dangerous levels of 35 to 40 degree below zero. The actual air temperature in southeastern Minnesota is forecast to drop to between 15 and 20 degrees below zero before rising into the single-digits below zero Sunday afternoon.

The extreme cold can result in frostbite on exposed skin in a matter of minutes and put a person at risk for hypothermia. Minnesota has already seen two deaths apparently caused by exposure to the cold in recent days. An elderly woman died after was found outside the Meadow Lakes Senior Living Center Friday morning and a 29-year-old man was found dead in a park in Eveleth on Thursday.
