Update, Dec. 27th 10:30 a.m.: The heavy winter storm left parts of the East Coast under more than 20 inches of snow yesterday, but Montgomery County and most of the D.C. Metro were only dusted by snow in the afternoon and evening.

A wind advisory is in effect for today until 9 p.m. The National Weather Service expects winds of 20 to 30 mph, with gusts of 45 to 50 mph. Gusts of that speed can affect driving ability.

Pepco's website warns that high winds can cause outages. Currently less than 5 people are without power in 20902.

Update, Dec. 26 12:55 p.m.: The Winter Weather Advisory is no longer in effect. The storm system continues its track towards the Atlantic coast. We can now expect a dusting to two inches of snow throughout Montgomery County.

Update, Dec. 26 11:55 a.m.: Light snow is currently falling in Chevy Chase, Bethesda, Silver Spring and Takoma Park as a WINTER WEATHER ADVISORY remains in effect through 6 a.m. Monday. Accumulations of 1-4 inches across the county are possible, according to WTOP.

Update, Dec. 26 1:05 a.m.: A Winter Weather ADVISORY remains in effect for Montgomery County from 6 a.m. Sunday to 6 a.m. Monday. Weather models are predicting anywhere from 1-5 inches of snow in the county.

Snow will be heavy at times, and wind gusts of 30-40 mph will cause blowing and drifting snow, reduced visibility and treacherous road conditions.

"Unlike most storms we have in the area, this one will see more significant snowfall totals to the east of the District than to the west," according to NBC Washington meteorologist Kim Martucci.

Update, 4:32 p.m.: TBD is now reporting that 6-10 inches of snow are expected between 6 a.m. Sunday and 6 a.m. Monday.

Original post, Dec. 25 11:01 a.m.: The National Weather Service has issued a WINTER STORM WATCH for Montgomery County from 3:00 a.m. Sunday through 6:00 a.m. Monday. A strong low pressure system has developed over the lower Mississippi Valley, and is expected to move through the region on Sunday.

Some weather models predict a foot of snow, while others forecast 1-5 inches with very windy conditions, WTOP reports. Higher accumulations are expected south and east of Washington, D.C. The storm watch includes all counties east of the Blue Ridge Mountains.

A winter storm watch is issued when there is the potential for significant snowfall and winter weather within 48 hours.
