On Wednesday at 2:57 a.m. an updated cold weather advisory was issued by the National Weather Service in effect until noon for Western Chester, Western Montgomery and Upper Bucks as well as Berks, Lehigh and Northampton counties.
The weather service comments, “Very cold wind chills as low as 11 below.”
“The cold wind chills as low as 10 below zero could result in hypothermia if precautions are not taken. Frostbite and hypothermia will occur if unprotected skin is exposed to these temperatures,” says the weather service. “Use caution while traveling outside. Put on gloves, a hat, and clothes that are acceptable. Keep pets indoors as much as possible. Make frequent checks on older family, friends, and neighbors. Ensure portable heaters are used correctly. Do not use generators or grills inside.”
Understanding cold weather alerts
Warning of cold weather: Exercise caution. When seasonably cold air temperatures or wind chill values—but not exceptionally severe ones—are anticipated or happening, a cold weather advisory is issued. Be sure you and your loved ones dress appropriately and cover exposed skin when venturing outdoors.
Warning: Extreme cold: Act now! When dangerously low air temperatures or wind chill values are predicted or already occurring, an extreme cold warning is issued. Avoid going outside if there is an extreme cold warning in effect. Make sure at least one other person is aware of your whereabouts, wear layers if you must go outside, and cover any exposed skin. When you reach your destination safely, update them.
Be ready for extreme cold watch. When extremely low air temperatures or wind chill values are possible, an extreme cold watch is issued. As with a warning, change your plans so that you don’t spend the coldest hours of the day outside. Update your winter survival gear and make sure your car has at least half a tank of gas left.
