More serious blackouts affecting some 35,000 were reported farther east and south.
Power companies said they were ready for the worst of the snowstorm Tuesday morning.
PPL, based in Allentown, announced Monday that all employees were on standby, and that 250 more line workers were brought in from sister companies in Kentucky and South Carolina to aid with eventual outages.
A spokesman for First Energy, the Ohio-based parent company of Met-Ed and JCP&L, said contract crews were moved into Easton on Monday.
"A unique challenge with a winter storm is being able to gain access to the outage locations, especially when large snow accumulations hamper travel," said Mark Julian, FirstEnergy's vice president of utility operations, in a news release.
Dave Bonenberger, PPL's vice president of distribution operations, promised "we will work around the clock until all customers are restored to power."
The storm picked up intensity overnight. At 7:30 a.m., no outages were reported in the Lehigh Valley or Warren County. PPL showed about 150 people without power between Lancaster and Reading, while JCP&L reported a couple hundred outages in southern Hunterdon County and isolated issues farther south and east.
Three hours later, outages were still sporadic. PPL had a handful of customers out in northern Northampton County. The First Energy companies mostly had minor disruptions, though up to 100 people had lost power in the Greenwich Township area.
Remaining outages in the region as of noon -- including some minor ones in Easton's College Hill and West Ward -- were expected to be fixed within a few hours.
Meanwhile, more serious blackouts were reported farther east and south in New Jersey where more than 35,000 lost power.
The storm -- for which local accumulation projections have been downgraded to 10 to 18 inches -- is expected to wrap up about 4 p.m.
While clearing the snow from driveways and sidewalks, UGI reminded natural gas users to also remove any accumulated snow and ice from outside vents on their furnace or other appliances, and their gas meter.
Blocked vents could make carbon monoxide build up inside the home, the company warned. A foul odor inside could be a sign that a vent is blocked.
