WASHINGTON (WJLA) — WJLA was there as D.C. Mayor Muriel Bowser declared a state of emergency because of the expected snowstorm.

This is the largest snowfall D.C. has had to deal with in a few years. The district stated that the danger zone is the period from Sunday to Monday, when temperatures transition from freezing to below-zero.

The mayor said she submitted a request to the National Guard for equipment and personnel for snow clearing.

“We're very concerned about the cold and the cold weather like this mixed with precipitation puts people in a lot of danger being outside, and weather like this, somebody could die,” Bowser said. “If you're outside and you're sleeping outside.”

The mayor and government agencies honed in on how intensely crews are going to be treating and plowing roads, and said you need to stay out of their way and out of the snow emergency routes until Tuesday morning. That could get extended based on conditions.

Right now, schools aren’t impacted. They already had a planned day off on Monday. During the announcement, the city also said if you know you are not physically able, don’t shovel snow or go outside. That's where they see the most emergencies and injuries.

The bus route will be impacted. Metro said there is no way around it because of road conditions. Metro said the question is how severe the impacts will be.

Some buses may be suspended. If you take the train, the metro is most concerned about the snow, the ice, and the cold temperatures. All three are working against the service this week. Metro C.E.O Randy Clarke said the cold could break the rails.

“If you do not need an absolute kind of life mission out on Sunday morning, especially, we ask that you please use some weather sense here, stay inside, look after each other as the mayor said, and then travel after that,” Clarke said.

If the snow and ice hit the third rail, that means no power and no train movement. Metro said as of this moment, it does not know what it’s going to do or the calls it's going to make with the metro lines, because it won’t know until the weather comes.

For now, trains will keep running until it's not safe. Metro Access is working on rescheduling trips.

Crews will be clearing from curb to curb. Move your cars and have your vehicles parked where you want them to ride out the storm before it snows. If you're in the way of plows or parked near curbs, you can get fined, your car towed, or your car stuck until the ice melts.
