The coastal storm that started dumping snow and rain on Massachusetts on Sunday is still going — and is forecast to intensify over the region starting Monday night into Tuesday.

Meteorologists with the National Weather Service said the “prolonged winter storm” will bring another round of accumulating snowfall as it amps up.

“The Tuesday morning commute could be heavily impacted, especially for those on I-95/I-93,” forecasters wrote.

Most of Massachusetts is under either a Winter Storm Warning, in effect through 7 a.m. Tuesday, or Winter Weather Advisory, in place through 1 p.m. Tuesday.

The heaviest snow will occur between 5 and 11 a.m. Tuesday, according to the service.

“We are right on the edge between a moderate snowfall and a big wind driven morning mess,” WBZ meteorologist Eric Fisher said of Tuesday’s morning rush hour. “Game of miles.”

Eastern Massachusetts is estimated to have seen just a few inches of accumulation so far, while the central and western parts of the state have observed higher totals. Much of the state is forecast to see between 4 and 8 inches more snow by the time the storm is over.
