Snow Totals

As the storm responsible for the heavy snow moved away from the Mid-Atlantic coast Saturday evening, the last of the Winter Storm Warnings were ended.   Final snow amounts exceeded 3 feet in a few spots in Maryland and northern Virginia, and record storm totals were set at BWI-Marshall (Maryland), Dulles (Virginia), and New Castle County (Delaware) Airports.  Both Philadelphia International and Reagan National Airports had their second greatest storm totals on record.

The 32.4 inches of snow at Dulles International Airport broke the previous storm total snowfall record of 23.2 inches from 7-8 January 1996.

The 24.8 inches of snow estimated at BWI Marshall Airport broke the previous storm total snowfall record of 24.4 inches from 16-17 February 2003.  This would also be the second highest storm total snowfall on record for the Baltimore area, behind the 26.3 inches which fell in the city on 27-28 January 1922.

The 25.8 inches of snow that fell at New Castle County Airport in Wilmington, Delaware, broke the previous storm total snowfall record of 22.2 inches from 8-9 January 1996.

Winds gusting to over 30 mph were common across the Mid-Atlantic region Friday night and Saturday, which created blizzard conditions.  As the storm intensified offshore Saturday, wind gusts over 50 mph were reported near the coast in New Jersey and the Delmarva peninsula.  The strongest gust reported was 61 mph at Lewes in Sussex County, Delaware.

Updated Impacts

Power Outages
About 200,000 customers were still without electricity Sunday morning, including over 60,000 in western Montgomery County, Maryland, and 50,000 in Cape May County, New Jersey.  Scattered outages continued across Ohio, Pennsylvania, West Virginia, Maryland, Virginia, Delaware, and New Jersey.

Pennsylvania American Water had a mandatory conservation notice in effect Saturday for all Allegheny and Washington County customers (in southwestern Pennsylvania).  A water treatment plant lost power for a time.

Transportation
Limited service resumed at Dulles International Airport Sunday morning.  The first flight arrived at 715 am EST.  Many of the initial flights will be arrivals as most aircraft flew out of the area in advance of the approaching snowstorm.  No flight operations were expected Sunday at Reagan National Airport.  Snow cleanup was continuing and the airport authority will assess the situation there later in the day.  The arrivals board on the BWI Marshall Airport showed that a handful of arrivals and departures scheduled for today, but there was no guarantee that those flights would actually take place.

Southwest Airlines had canceled all flights out of the region Sunday and most of their Monday morning flights.

In a repeat of Saturday, Amtrak cuts many of its Sunday trains along the Eastern Seaboard.

The Washington Metro expected to open Sunday with underground rail service, but Metrobus and MetroAccess paratransit service would not operate.  Most DC suburban bus services were not operating Sunday.

Southeastern Pennsylvania Transportation Authority (SEPTA) subway, regional rail and trolley lines in and around Philadelphia were operating on a normal Sunday schedule. Two bus routes were suspended and the rest were running with delays because of icy roads.

In Pittsburgh, bus and light-rail service had been suspended Sunday.  The Port Authority of Allegheny County was assessing road conditions.

Most major highways were open, but many secondary and local roads had yet to be cleared.

Other Impacts
The Smithsonian Museums and the National Zoo were also closed again Sunday.

Heavy, wet snow collapsed several roofs in the Washington metro area, including the roof at Joshua Temple Church Ministry in Northeast DC.

Outlook

Another snowstorm is expected across the Mid-Atlantic region Tuesday and Wednesday.  A storm moving across the country will be dropping heavy snow across higher elevations of the Southwest states today, and is forecast to cross the Central Plains and Midwest on Monday before reaching the Mid-Atlantic Tuesday.

Computer models were suggesting that a strong coastal storm could spin up Wednesday east of either New Jersey or the Delmarva peninsula, and significant additional snow accumulations are possible.

As of early Sunday morning, Winter Storm Warnings and Advisories were in effect from eastern California to northwest Arkansas, with Winter Storm Watches further east through much of Indiana.
