A blizzard slammed into the greater Philadelphia area this weekend, dropping as much as 21 inches of snow in many parts of the region in one of the more significant winter events in recent history.
Strong winds and thunderstorms accompanied the storm in places, and the height of the blizzard saw two inches or more of accumulation per hour.

“The blockbuster blizzard has all but shut down travel in a heavily populated, very busy region of the nation with road closures and thousands of flight cancellations and delays from this weekend to Monday,” Accuweather said. “These effects will continue into Tuesday and perhaps Wednesday until aircraft and crews are relocated, schedules changed and crews have a chance to clear the snow.”

It’s the first storm classified as a “blizzard” by Accuweather in the Philadelphia area in four years.
Here’s a glance at some of the most notable impacts Monday morning.
Roads inundated, vehicle restrictions in place
Officials with the Pennsylvania Department of Transportation are urging residents to avoid travel if at all possible.
Drivers who do take to the roads will see reduced speed limits on all major highways around the greater Philadelphia region, including:
Interstates 76, 95, 295, 476, 676U.S. Routes 1, 30, 202, 422State Routes 63, 100 Spur and 309
Commercial vehicles are not permitted on roadways, nor are school buses, commercial buses, motor coaches, motorcycles, RVs, motorhomes, or any passenger vehicles towing other vehicles.
“Restrictions will be lifted as quickly as possible when conditions are safe,” PennDOT said Monday.
Snow plows worked through the night in many parts of the region, treating the roads and attempting to clear snow.
Power outages
Widespread power outages are in effect around the area, with nearly 10,000 customers impacted as of 9:30 a.m. Monday, according to PECO.
The storm brought down trees and power lines in various parts of the region.
The bulk of those outages are in Delaware (4,624) and Montgomery (2,671) counties, with outages also hitting Bucks (951), Chester (722), and Philadelphia (351).
Restoration times range from a few hours to a few days, depending on the nature of the outage.
SEPTA Regional Rail
SEPTA suspended all bus service — including the G buses and trolleys — at 10 p.m. Sunday. Buses will be suspended until further notice.
Regional Rail service is suspended until safety inspections can be completed.
School closures
Nearly all schools throughout the region have declared either traditional snow day, a remote instruction day, or a flexible instruction day for Monday. Determinations for Tuesday could be made early on Monday given the amount of accumulation and additional inclement weather in the immediate forecast.
More snow on the horizon
Snow could continue through the morning, and “blowing snow” is possible into the evening hours Monday night. Temperatures will drop to 23 overnight, keeping all the recent accumulation cold.
Another round of snow appears likely Tuesday, with less than an inch of new accumulation possible Tuesday night, according to the National Weather Service.
