The Capital Weather Gang advises: "Some time after 2 or 3 p.m., once sustained winds reach 30-40 mph, and it’s gusting over 50 mph, I would not advise going out. During Hurricane Irene, a number of lives were lost when people were crushed by falling trees - some in cars. You’re best bet will be to stay inside from mid-afternoon Monday through Monday night, and only travel if absolutely critical."

UPDATE 10 a.m. -- The National Weather Service has issued a high wind warning, which is in effect from 8 a.m. Monday to 8 p.m. Tuesday. Wind gusts of more than 45 mph are expected Monday morning and wind gusts up to 60 mph are expected Monday afternoon into Tuesday.
Coupled with heavy rain, the high winds will lead to significant tree damage and power and communication outages, the National Weather Service advises.
For those who live near large trees, the National Weather Service recommends staying in the lower level of your home or seeking shelter elsewhere if possible; residents should also refrain from traveling and stay indoors.
5:30 a.m. -- Thousands of Northern Virginians spent Saturday stocking up on staples, gassing up their cars and generally preparing for Hurricane Sandy, the mega hybrid storm dubbed "Frankenstorm" expected to affect the D.C. area beginning Sunday night, according to forecasters.
Residents can expect the worst of the storm to hit the area with high winds and heavy rain from about noon on Monday to noon on Tuesday, NBC-4 chief meteorologist Doug Kammerer reported on the Saturday 11 p.m. newscast.
The hurricane, with winds of 75 miles per hour Sunday morning, was moving northeast at 14 miles per hour along the South Carolina coastline; the center of the storm is expected to hook over to the Mid-Atlantic shoreline between Delaware and New Jersey. (Once the hurricane makes landfall late Monday night or early Tuesday its official name will likely be Post-tropical Cyclone Sandy according to the National Hurricane Center.) Tropical storm-force winds extend more than 500 miles from the center of this relatively disorganized hurricane.
Although there is no forecast for snow in the Northern Virginia area, VDOT is sending snowplows to roadways near West Virginia, said VDOT’s Charlie Kilpatrick.
Dominion Virginia Power says to expect prolonged outages. Gov. Bob McDonnell urged families to grab extra blankets to stay warm during possible outages, with temperatures dipping into the 40s this week.
In addition to potential flooding and power outages, a major concern for all state agencies involved in emergency operations is trees coming down, Gov. Bob McDonnell said in a conference call Saturday. Many trees still have most of their leaves, and strong wind and saturated soil mean a strong likelihood of trees uprooting.
High Wind, Coast Flood Watches in Northern Virginia and D.C.
The National Weather Service late Saturday issued a High Wind Watch for Northern Virginia from Sunday night through Tuesday at midnight. The weather service expects the area to see sustained winds of between 35 to 45 miles per hour, and wind gusts of up to 60 miles per hour.
Northern Virginia is also under a Flood Watch, with expected rain of at least 3 to 6 inches in the area.
The area is also under a Coastal Flood Watch for areas near the Potomac River.
