A Red Flag Warning means fires can spread quickly and grow out of control under the current weather conditions, including low humidity, gusty winds, and dry fuels. Residents should not burn in those counties where a Red Flag Warning is in effect and should check any recent burning they might have done to ensure the fire is completely out.

The Wisconsin DNR has issued a Red Flag Warning for multiple northern Wisconsin counties for extreme fire danger.

Elevated fire danger will exist May 12-13 as warm temperatures, low humidity levels and gusty winds become mixed with dry, fine vegetation and grasses, according to the weather service.
