11:15 a.m. - High wind warning changed to wind advisory
The worst of the winds have likely already occurred and there are some indication the top gusts are starting to decrease a bit. As such, the National Weather Service has changed the high wind warning to a wind advisory for much of the region. Gusts could still exceed 50 mph, but such instances should become more isolated and less frequent as the afternoon wears on.
10:25 a.m. - Scattered 50+ mph gusts causing some downed trees, outages, and damage
Mid-morning, winds are sustained in the 25-to-35- mph range with gusts to 40 to 50 mph. Some isolated gusts of 50 to 60 mph have been reported since early this morning. Here are some peak gusts so far (full list):
- Silver Spring: 60 mph
- Thurmont: 59 mph
- Upper Marlboro: 59 mph
- Seat Pleasant (Prince George’s County): 58 mph
- Leesburg: 58 mph
- Gaithersburg: 58 mph
- Catholic University: 58 mph
- Andrews Air Force Base: 56 mph
- Arlington: 55 mph
- Hagerstown: 55 mph
- Dulles: 53 mph
- Frederick: 49 mph
We have received reports of downed trees and some isolated wind damage across the region. In terms of outages, Poweroutage.Us reports about 40,000 customers in the dark across the region, including 6,000 with Pepco, 11,000 with Baltimore Gas and Electric, and 20,000 with Dominion.
Winds, which are peaking in intensity now, should begin to very slowly ease this afternoon.
6:50 a.m. - Wind advisory upgraded to high wind warning
Overnight, the National Weather Service upgraded the wind advisory in effect today to a high wind warning for most of the region, with the exception of Southern Maryland (where a wind advisory is in effect). The warning calls for sustained winds of 25 to 35 mph with gusts to 50 to 60 mph. The strongest gusts are expected this morning.
“.Damaging winds will blow down trees and power lines,” the Weather Service cautioned. “Power outages are expected. Travel will be difficult, especially for high profile vehicles.”
While the Weather Service has issued this warning for gusts of 50 to 60 mph in the immediate Washington area, model data we’ve reviewed suggest such gusts will be isolated here, and perhaps a bit more common in northern Maryland and along Interstate 81 to our west. The strongest gusts will be found at high elevations.

High winds rip across the region today but then we have three straight days of calm, unremarkable weather. Our next chance for precipitation comes Friday, most likely in the form of rain. It could linger into the first part of Saturday before cold, dry air funnels back in.

Today (Monday): The sun shines but winds howl, especially this morning. Gusts could reach 40 to 50 mph before easing back to 30 to 40 mph in the afternoon. Highs range from 40 to 45, but it feels like the 30s much of the day. Confidence: Medium-High
Tonight: Winds slowly subside overnight but remain gusty in the evening, registering above 30 mph at times. By morning, gusts will be closer to 10 to 15 mph as low temperatures reach the upper 20s and low 30s. Confidence: Medium-High
Tomorrow (Tuesday): This is a great-looking winter day. Winds are way down (gusts only 10 to 15 mph), the sun is out and it’s not too cold. Highs reach the mid- to upper 40s. Confidence: High
Tomorrow night: A few clouds, light winds and cold. Lows range from near 20 in our colder spots to the upper 20s downtown Confidence: High
A LOOK AHEAD
Wednesday and Thursday are both seasonably chilly winter days, but not at all unpleasant. Highs are in the mid-40s on Wednesday and in the upper 40s to near 50 on Thursday. Skies both days are partly sunny. Wednesday night is partly to mostly cloudy and cold, with lows in the 20s to around 30. Confidence: Medium-High
Light rain is likely late Thursday night into Friday, and it could mix with some sleet or snow at the onset. But temperatures probably aren’t cold enough for any real slipperiness with lows in the mid-30s and mostly above freezing early Friday (but the exception might be in our colder areas well to the north and northwest). It’s chilly Friday, with highs around 40 to 45. Some light rain may continue Friday night, with lows near 40. Confidence: Medium
There may be some rain showers to start the weekend Saturday morning, but clouds should decrease in the afternoon, with temperatures rising into the 50s (maybe higher if the sun comes out early enough). Drying out and turning windy and much colder Saturday night and Sunday, with lows in the 20s and highs in the 30s to near 40. Confidence: Medium
SNOW POTENTIAL INDEX
A daily assessment of the potential for at least an inch of snow in the next week, on a zero-to-10 scale.
1/10 (→): Can’t rule out a few wet flakes early Friday, but it looks like the period around March 5-7 could be our next chance.
