A Cold Weather Advisory is in effect from 7pm Monday until 10am Tuesday for DC, and portions of central, northeast, and northern Maryland (including all of Montgomery County), and central, northern, and northwest Virginia.
Per the National Weather Service (NWS), “Very cold wind chills as low as 5 degrees below zero expected. Frostbite and hypothermia will occur if unprotected skin is exposed to these temperatures. Wind chill values can lead to hypothermia with prolonged exposure. To prevent water pipes from freezing, wrap or drain or allow them to drip slowly.
Use caution while traveling outside. Wear appropriate clothing, a hat, and gloves. 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.”
