An impulse from the west coast traversed the midsection of the country, then developed into a low pressure system as it tracked across the Gulf states before intensifying along the Carolina coast into a major nor'easter, producing record or near record snowfall through a good part of Delaware. It then moved out to sea after passing by the mid-Atlantic coast early on January 24th.
Snow began falling during the mid afternoon hours on Friday, January 22nd, then continued, heavy at times, Friday night into early Sunday morning. Wind gusts up to 60 MPH produced near-blizzard conditions as visibilities dropped to one-quarter mile or less in spots. Some representative snowfall totals include: 16.3 inches in Talleyville, 14.8 in Hockessin, 12.0 in Claymont, 11.2 in Prices Corner, and 10.5 in Newport, all in New Castle County. In Kent County, reports include 17.2 inches in Woodside, 14.8 in Harrington, 14.2 in Dover, 12.0 in Magnolia, and 9.7 in Smyrna. In Sussex County, reports include 8.8 in Laurel, 7.8 near Georgetown, 7.0 in Seaford, 5.2 in Bethany Beach, 4.2 in Milton, and 3.0 in Rehoboth Beach.
Some wind gusts include 75 MPH at 0735EST on the 23rd in Dewey Beach, 64 MPH at 0512EST on the 23rd at Sussex County Airport in Georgetown, 50 MPH at 0730EST on the 23rd in Rehoboth Beach, and 53 MPH at 0551EST on the 23rd at New Castle County Airport.
A 44-year-old male from Magnolia (Kent County) died while shoveling snow around his home on January 23rd.
At one point during the storm, up to 117,000 customers were without power. Outages were concentrated closer to the coast where the strongest winds occurred.
The Delaware Department of Transportation spent approximately $3.5 million dollars to clear and maintain the state's highways and roadways.
Moderate to major flooding occurred along the Delaware coast and associated back bays during this event. Record flooding was recorded in many spots, including the ocean front at Lewes. Route 1 was closed between Dewey Beach and the Indian River Bridge due to flooding. Beach erosion was extensive, but property damage was minimal considering the record water levels during this event. Some damage was noted on the boardwalk on the north end of Rehoboth beach from Grenoble place to Surf avenue totaling from 150 to 400 K. After viewing the beach areas, Governor Markell noted the importance of investments in beach replenishment and dunes in limiting damage in this storm. Sand dunes and Stormwater pipes were damaged as well and Delaware is looking for $2.5M in disaster relief. The day after the storm subsided, the Small Business Development Center extended an offer of free services to help businesses impacted by the storm to get up and running again, but a week after the storm, no businesses have taken the center up on the offer. Damage estimates total $0.13 million in New Castle County, $0.553 million in Kent County, and $0.778 million in Sussex County. These estimates do not include damage to beaches maintained by the U.S. Army Corp of Engineers, which include Dewey and Lewes Beaches.
Delaware Governor Jack Markell declared a State of Emergency beginning 5 PM Friday, January 22nd, which ended at midnight Sunday night. Schools and many businesses recessed early on Friday afternoon in anticipation of the storm. On March 16t 2016, President Obama declared the state of Delaware a federal disaster area. This declaration makes federal funding available on a cost-sharing basis for emergency work and the repair or replacement of facilities damaged by the severe winter storm. Federal funding is also available on a cost-sharing basis for hazard mitigation measures statewide. This declaration does not provide funding for beach replenishment made necessary by erosion caused by the storm.
The combination of a strong onshore flow and high astronomical tides associated with a coincident full moon produced record tidal flooding along the Delaware coast and lower Delaware Bay during the morning high tide cycle on Saturday, January 23rd. The NOS gauge at Breakwater Harbor (Lewes) peaked at 9.27 feet MLLW at 812 AM. This broke the previous record of 9.2 ft MLLW set on March 6, 1962. A prolonged onshore flow through three consecutive tide cycles produced moderate flooding for the Saturday evening high tide, and minor flooding for the Sunday morning high tide. This prolonged onshore flow also produced flooding in the back bay areas.
