Powerful Storms Rumble Across Eastern Seaboard

Powerful thunderstorms will pepper the Eastern Seaboard through early Monday morning. Damaging winds will be the primary risk, although a few tornadoes and hail will be possible too.

Dangerous weather will continue to precede a potent cold front dividing summer warmth and humidity from much cooler, drier air behind it. This activity will happen until predawn Monday, exiting the Mid-Atlantic and New England beaches last. Farther south, there may be a smattering of strong to severe thunderstorms through early tonight.

Severe Thunderstorm Watches stretch from parts of southern New York down into eastern Pennsylvania, New Jersey and the Delmarva region. Cities under the watches include Philadelphia and Wilmington, Del.

Scattered damaging wind gusts up to 70 mph, quarter size hail, and a few tornadoes will be possible within the most intense activity.

Flooding will be part of the thunderstorms makeup too. A quick 1 to 3 inches of rainfall will occur in a short time, with isolated totals of 4 to 5 inches possible. This could lead to urban and poor drainage flooding, and could promote river, stream, and creek flooding. Flood Watches remain in effect across northern and western Maine, northern New Hampshire, and northern Vermont. Remember, if you approach a road covered by water, it is best to “Turn Around, Don’t Drown!”

Make sure to know the difference between a watch and a warning should they be issued. A "watch" means that conditions are favorable for severe weather to occur, and to be on alert for any rapidly changing conditions. A "warning" means that severe weather is imminent, and you should act fast to remain safe.

The best way to remain safe is to stay prepared and informed about your local weather. Have a severe weather kit packed with a battery-operated radio, water, and non-perishable food items. Also, check the WeatherBug app frequently for any updates on today's severe weather. Remember, "When Thunder Roars, Go Indoors!"
