Wednesday's storm caused 40 percent more power outages than the back-to-back February 2010 blizzards combined, according to a Baltimore Gas and Electric Company statement released Friday afternoon. This is part of the reason why scattered outages may extend into Sunday, officials said.

Members of the Perry Hall, Kingsville and White Marsh communities were hit hard by power line damage. On Wednesday evening, an estimated 5,000 customers lost electricity between Interstate 695 and the Harford County line, along U.S. Route 1 and Pulaski Highway.

While the vast majority of outages were repaired within a few hours, the BGE power outage map showed hundreds of area residents without power overnight and into Thursday morning.

On Friday afternoon, some scattered outages, pockets of one to 15 customers, spent their third day without electricity. One larger community of 251-1,000 customers, on the north side of Pulaski Highway, also remained without power.

While power was restored to nearly 90 percent of customers by Friday afternoon, about 2,650 outage-related jobs across Central Maryland remained, said A. Christopher Burton, a senior vice president of BGE, in an official statement.

Burton added: "The remaining outage work will likely only restore a handful of customers at a time, unlike the earlier work which typically restored hundreds or thousands of customers at a time."

By Friday afternoon, more than 2,000 people, including 800 out-of-state workers— from Pennsylvania, Ohio, Indiana, Virginia, North Carolina, Tennessee, Kentucky, New Jersey, New York and Connecticut—were actively working to restore power in BGE's service area.
