Second round of severe storms triggers flooding for parts of DC region

A second round of thunderstorms has caused major flooding for parts of the D.C. region.

After an afternoon full of sunshine and temperatures in the 90s, heavy rainfall and hail impacted several areas Tuesday night.


One of the areas hit hardest was Frederick, Maryland. A Flash Flood Emergency was declared for the city as emergency crews worked to help rescue stranded drivers in high water.

"At 904 PM EDT, emergency management reported widespread flash flooding in and near Frederick with numerous water rescues, water inside buildings, and many roads flooded," the National Weather Service reported. "Up to six inches of rain have fallen and more heavy rain is moving back into Frederick over the next hour. Flash flooding is already occurring and may continue to worsen!"

"Many roads are not passable at this time," the Frederick Police Department tweeted Tuesday night. "The water is not easy to see in the dark. Please stay off the roads. We are responding to calls as fast as possible and tow trucks are in high demand right now."

A Severe Thunderstorm Watch issued for Washington D.C. and several surrounding counties in Northern Virginia and Maryland expired late Tuesday night. The watch warned of threats of hail, powerful winds and lightning.

A Flash Flood Watch also went into effect until 1 a.m. for the majority of the D.C. area.

Drivers are being advised to stay off the roads and avoid traveling in any areas with high water, underneath trees or wooded areas until the storm threat has passed. Turn around, don't drown!

A day ago on Monday, severe storms knocked out power to thousands as strong winds, heavy rain and hail pounded the D.C. region. Flooding conditions were seen in some parts of the region as were downed trees and power wires. Some schools cancelled classes Tuesday after storms caused outages to school buildings.
