As of Thursday evening, there were about 107,000 households in Massachusetts still without power following Wednesday night's powerful storm, according to the Massachusetts Emergency Management Agency. That number is down from a high of around 230,000 this morning, the agency said in a statement.

MEMA spokesman Christopher Besse said the continuing high winds have slowed efforts to fix downed wires across the state, and it's not yet clear when all power will be restored.

"It looks like many of these people who are out [of power] now will still be out tonight, but they're certainly making some great progress along the way," Besse said. "The utility companies are still working on those exact restoration timelines."

More information about the number of Massachusetts households without power can be found on MEMA's website.

A spokesperson for Eversource said crews will continue working until all customers have power, but that may not come until Friday.

The storm left thousands of homes and businesses without power and caused massive disruptions on the roads and the train tracks on Thursday. The Cape and Islands and the North and South Shores had some of the largest concentrations of power outages, and that has translated to school closures as well. Multiple towns closed schools for the day, including Scituate, Marshfield, Salem, Danvers, Beverly, Falmouth and Barnstable.

Downed branches blocked roads Thursday morning, and there were cancellations or delays on nearly every major commuter rail line — including Providence, Framingham, Fitchburg and Greenbush. Flooding also caused problems on the Lowell Commuter Rail line.

Back in the city, the D branch on the Green Line ran shuttle buses between the Riverside and Newton Highlands stations because of a massive tree on the tracks.

MEMA has brought in the Red Cross and the departments of public utilities and health to coordinate the state response.

Kim Buttrick, a meteorologist with the National Weather Service in Massachusetts, said the storm system met the definition of "bombogenesis."

Storm intensity is measured by central pressure— the lower the pressure, the stronger it is. A storm is considered a "bomb" when the pressure drops rapidly.

"That's why we ended up with strong, sustained winds and wind gusts," Buttrick said. "It's an indicator of an extremely powerful storm and not something to ignore."

Buttrick forecast that the storm would continue traveling north and northeast, across the Maine coast through Thursday, reaching north of Nova Scotia by Friday morning.

Most areas saw rainfall totals of 1 to 3 inches, though some areas of southern New England got about 4 inches.
