The National Weather Service in Riverton has issued a wind chill advisory -- with potentially hazardous health effects -- for Natrona County from 11 p.m. today through 8 a.m. Sunday.

"Hypothermia and frostbite may occur even with brief exposures," according to the Weather Service.

Gusty northeast winds with very cold temperatures are expected to produce wind chill values of minus 25 degrees to minus 30 degrees.

That can hypothermia and frostbite in 30 minutes to exposed skin if precautions are not taken.

Make sure you wear a hat and gloves when you go outside.

Meanwhile this evening, the Weather Service says an area of moderate to heavy snow will push south and southeast across the Wind River Basin and Natrona County.

It expects between one and two inches, and the snowfall quickly will cause roads to become slick and snow-packed.
