Freezing rain may be on the way for the Reston area overnight.
The National Weather Service has issued a freezing rain advisory for the area from 7 p.m. Tuesday to 6 a.m. Wednesday.
The advisory calls for up to 1/10 of an inch of accumulation. That may not sound like a lot, but a coating of freezing rain/ice can wreak havoc with roads and schools.
The NWS says precipitation will change to all rain Wednesday morning as air temperatures rise above freezing.
A freezing rain advisory means that periods of freezing rain will cause travel difficulties, so residents should be prepared for slippery roads, the NWS said.
Dulles International and Reagan National airports are open, and operations are normal.
An approaching winter weather system will impact scheduled flights to and from the Washington, D.C. area this evening and Wednesday. Passengers should check the status of these flights directly with their airline.
The Metropolitan Washington Airports Authority says it expects widespread flight cancellations between 8 p.m. tonight and 12:00 p.m. Wednesday. Consult directly with your airline about flight status and rebooking options. MWAA said Reagan National should not have as much of an impact locally, but delays may be affected from weather in other cities.
Reston Now will update this story with any hazardous roads or school closures.
