MILWAUKEE (AP) — Wisconsin authorities are warning residents about weather conditions after more than 30 wildfires were reported throughout the state Saturday.

Much of the state is under a burn ban due to forecasts of low relative humidity, gusty south winds and above normal temperatures, according to the National Weather Service.

Authorities said 36 fires were reported over 100 acres, mostly in northern and central Wisconsin, and at least five structures burned.

The fire danger is listed as high or very high for 71 of the state’s 72 counties, the Department of Natural Resources said. Vilas County is under a moderate fire warning.

The weather service said there has been little or no snow pack and mild temperatures throughout the month, as well as below normal winter snowfall.
