Hurricane Irene left hundreds of thousands without power, took down trees and power lines and flooded roadways over the weekend. But now it’s Monday morning, and people still need to get to work.

So here’s what you need to know for Monday morning’s commute:

Watch out for dark traffic signals and blocked roadways during your commute

Power outages, flooding and debris remain the biggest problems for commuters this morning. Even if your home was unaffected and you can get out okay, remember that plenty of traffic signals could be dark while lanes and roads might be closed due to water or debris.

If you encounter an intersection without working traffic signals, remember to treat it as a four-way stop. If you encounter barriers, do not move them and drive around. If you see a flooded roadway and you aren’t sure your car can make it through the water, don’t take the chance. Just turn around and take another route.

Metro plans full service

Metro said it expects normal service on Monday, though some Metrobus routes might encounter some delays or detours due to fallen trees, flooding or related cleanup work.

UPDATE: The following Metrobus routes have minor detours due to storm damage, according to Metro: J11, J12, J13, V9, F14, W4, W8, 94 and the D and H lines.

The entrance escalators are currently down at the Wheaton station due to a mechanical problem, but the station remains open and shuttle bus service has been requested.

Commuters return to the road

A scan of local traffic cameras shows that conditions have returned to normal in some areas around Washington. In other words: congestion. Traffic is backed up on eastbound I-66 at the Beltway, on I-395 North approaching the 14th Street Bridge and on the outer loop of the Beltway at University Boulevard. If you didn’t know a storm had hit over the weekend, you’d think this was just a normal Monday morning commute.

An accident on the outer loop of the Beltway near the Springfield Interchange is blocking the right lane and right shoulder.

Water Street is closed in downtown Upper Marlboro, according to the Maryland State Highway Administration. There are detour signs guiding people who want to access the courthouse.

Commuter rail: MARC, VRE operating, with some delays and reductions

MARC riders can expect full service on the Camden and Brunswick lines, while Penn Line trains will be running on a reduced “S” schedule on Monday morning. Power is still out at several MARC stations, so passengers who ride pre-dawn or late evening trains are encouraged to bring a flashlight to the station in case lighting has not been restored.

Amtrak train 151 left Perryville 15 minutes late. Brunswick Line train 876 is running 10 minutes late as it approaches Gaithersburg. Penn Line train 511 was delayed earlier this morning with mechanical problems; it departed Odenton 36 minutes late and is overcrowded, according to the MTA. Penn Line train 419 is running 10 minutes late, while Penn Line train 517 is 17 minutes late.

VRE riders can expect full service, but there could be some delays on the Fredericksburg Line due to power outages along that route.

Flight delays and cancellations to continue Monday

All three area airports remained open all weekend, but scores of flights were canceled at Baltimore Washington International, Reagan National and Dulles International airports over the last few days. Delays and cancellations are expected to continue on Monday, as officials warned it takes a few days for schedules to settle down after severe disruptions like this.

School year begins in Loudoun, Frederick and (most of) Montgomery counties

Classes kick off in Loudoun and Frederick counties this morning, along with most of Montgomery County. That means drivers should remember to slow down for school zones and expect added congestion near schools.

More than a dozen schools are closed in D.C., along with schools in Prince George’s, Howard, Anne Arundel, Calvert, Charles and St. Mary’s counties.

Amtrak plans to operate most of the Northeast Regional trains connecting Washington and Philadelphia on Monday, but all service between Philadelphia and Boston has been canceled. All Acela Express service between Washington and Boston has also been canceled. All Northeast Regional trains between Washington and Newport News have also been canceled.
