Provincetown and most of Nantucket remained without power on Tuesday as a winter storm slammed into Massachusetts and significantly hammered the southeastern part of the state.

The number of power outages in Massachusetts stood at more than 220,000 just before 2 p.m. as state officials grappled with the third major storm in two weeks.

More than half the customers in Orleans and Yarmouth were without power, according to the map maintained by the Massachusetts Emergency Management Agency.

Further up the coast, 80 percent of customers in Duxbury (5,571) were without power.

At a noontime press conference, when the number of power outages was roughly at 175,000, Gov. Charlie Baker warned that he expected the number to increase, particularly on the South Shore and the Cape as those communities experienced powerful wind gusts.

With reports of many wires down on the Cape, Baker said residents should keep batteries on hand and charge their devices.

"They are out where they can be to deal with some of the downed lines," Baker said of utility crews.

The governor added that it would be difficult for the crews to start working on the down lines until the snow stops falling and the wind dies down.

Baker urged people to keep staying off the roads.

Baker said there is little traffic on the roads and lower ridership on the MBTA, which is running a reduced, Saturday-style schedule on Tuesday.
