Full Notification

One or more bands of snow squalls will be moving east at 50 to 55 mph along the leading edge of an arctic airmass, with the potential to impact portions of eastern Pennsylvania and adjacent areas of New Jersey and northern Delaware. Near whiteout conditions and a quick one half inch of snow in just 10 to 15 minutes will lead to dangerous travel conditions as a result of the very poor visibility and snow or ice covered roads. Winds will gust up to 50 mph in the squalls. If possible, delay any travel until the mid to late afternoon hours. If you are traveling, your recognition of these squalls and the actions you take to get off the road or help to gradually slow traffic could prevent a high speed, multi-vehicle accident and save your life and the lives of others. If you see terrain features and objects off in the distance being obscured by heavy snow within the dangerous snow squalls, take quick action to pull off the road to a safe location, such as a parking lot or driveway to wait out the squall. If you are on an interstate, it's best to get off the road at the nearest exit as soon as you notice the squall to ensure the safety of you and your passengers. If there isn't an opportunity to safely exit the interstate, slow down gradually, well before entering the squall and turn on your flashing hazard lights.
