The National Weather Service has issued a winter storm watch for Fairfax Station and Northern Virginia starting Tuesday evening until Wednesday evening. Significant snow is expected to begin falling between 10:00 p.m. and 4:00 a.m.

A winter storm watch means there is a potential for significant snow, sleet or ice accumulations that may impact travel. An accumulation of more than 5 inches of snow is possible with the potential of heavy snowfall within the watch area.

The NWS reports that precipitation will be mixing and changing to snow Tuesday night, with snow continuing through Wednesday evening. The weather will cause difficult driving conditions. Heavy wet snow could also cause possible power outages.

NWS, however, notes that "uncertainty remains with the track of the low and location of the rain/snow line," which ultimately will determine snowfall totals.

Residents are encouraged to stock up today on winter preparedness emergency supplies and other preparedness items.
