On Tuesday at 3:19 a.m. an extreme cold warning was issued by the National Weather Service valid for Wednesday between 1 a.m. and 10 a.m.

The NWS states, "Dangerously cold wind chills as low as 10 expected."

"Frostbite and hypothermia will occur if unprotected skin is exposed to these temperatures. An extended period of freezing temperatures could cause ruptured water pipes. Frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing," explains the NWS. "Wear protective clothing such as a hat, face mask and heavy gloves or mittens if you have plans to be outdoors. To prevent freezing and possible bursting of outdoor water pipes they should be wrapped, drained, or allowed to drip slowly. Those that have in-ground sprinkler systems should drain them and cover above-ground pipes to protect them from freezing. Drain in-ground sprinkler systems and cover above ground pipes. Keep pets indoors as much as possible. Make sure outdoor animals have a warm, dry shelter, food, and unfrozen water. Make frequent checks on older family, friends, and neighbors. Ensure portable heaters are used correctly. Do not use generators or grills inside. Monitor the latest forecasts and warnings for updates. Use caution while traveling outside. Wear appropriate clothing, a hat, and gloves. Take steps now to protect tender plants from the cold."

Understanding cold weather alerts

Extreme cold warning: Take Action! An extreme cold warning is issued when dangerously cold air temperatures or wind chill values are expected or occurring. If you are in an area with an extreme cold warning, avoid going outside. If you have to go outside, dress in layers, cover exposed skin, and make sure at least one other person knows your whereabouts. Update them when you arrive safely at your destination.

Extreme cold watch: Be Prepared. An extreme cold watch is issued when dangerously cold air temperatures or wind chill values are possible. As with a warning, adjust your plans to avoid being outside during the coldest parts of the day. Make sure your car has at least half a tank of gas, and update your winter survival kit.

Cold weather advisory: Be Aware. A cold weather advisory is issued when seasonably cold air temperatures or wind chill values, but not extremely cold values, are expected or occurring. Be sure you and your loved ones dress appropriately and cover exposed skin when venturing outdoors.
