After a warmer-than-usual start to spring, the D.C. region is expected to be hit overnight with a throwback blast of winter.
The National Weather Service has issued a Freeze Warning for much of the area, including Fairfax County, starting at midnight and continuing until 9 a.m. tomorrow (Wednesday).
Temperatures could dip as low as 30 degrees, presenting a threat to outdoor plants and plumbing infrastructure, according to the agency.
“Frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing,” the NWS said, advising residents to take precautions now to “protect tender plants from the cold.”
At the same time, windy yet dry weather has created an elevated danger of fire throughout the region, a threat that’s predicted to persist through early next week, the NWS said this morning (Tuesday).
The Fairfax County Fire and Rescue Department shared fire safety tips, including proper disposal of cigarettes, keeping vehicles off dry grass and avoiding outdoor burning.
