NoVA, DC Weather: Patchy Frost Possible In Hazardous Outlook

MARYLAND — As temperatures drop into the 30s overnight, the National Weather Service issued a hazardous weather outlook for the District and parts of northern Virgina.

The week will start off cool and rainy before 70s return at the start of the weekend.

"Low temperatures are expected to be below normal tonight," the weather service said.

Two things may be at risk during the cold night, officials said: plants and pipes.

Frost may harm sensitive vegetation, so authorities advised bringing tender plants inside or covering them to protect them from the cold.

Outdoor plumbing may burst, so people should wrap, drain or drip slowly any water pipes outside, officials said.

Communities in the hazardous weather outlook include the District of Columbia, Prince William, Manassas, Manassas Park, Fairfax, Arlington, Falls Church, Alexandria, Stafford and Spotsylvania.
