Monday's snowfall in Maine, New Hampshire; more to come Wednesday
Heavy snow has already fallen in much of the Northeast, with storm totals exceeding one foot of snow in some areas as of Monday.
Parts of Maine and New Hampshire saw snowfall totals ranging from 2 to 17 inches in the system that plowed through the region earlier this week, the weather service office in Portland, Maine reported Monday night.
Some areas could see an additional 6 inches or more in the coming days, the Portland weather service office said Tuesday, noting that precipitation will "gradually switch to rain from south to north by Thursday morning."
The weather service in Boston also noted that more snowfall was expected across New England on Wednesday, with 4 to 6 inches expected in parts of northern Massachusetts from Wednesday into Thursday.
"This next storm will pack a 'front end punch,' with most accumulation occurring overnight," weather service Boston said.
Winter weather leads to car crashes, deaths
Heavy snowfall has also led to dangerous travel conditions - and fatal car crashes.
In New Hampshire, state police said they had responded to 90 "crashes and vehicles that have gone off the road" between 5 a.m. and 2 p.m. EST on Monday. Whiteout conditions and snow-covered roadways created "hazardous traveling conditions," police said.
Amid Monday's and Sunday's winter weather, fatal car crashes have been reported.
On Sunday evening, a 31-year-old Massachusetts man died in a wrong-way crash on Interstate-290, Massachusetts State Police said.
School closures, delays across the US
Schools around the country braced for snow and winter weather by closing schools or making plans to shut down early.
Oklahoma City Public Schools shifted to virtual classes at home, the school district said in a Facebook post. In Texas, districts including the El Paso Independent School District were starting classes late Tuesday because of poor weather conditions, including the possibility of snow flurries, local outlet KTSM reported.
Some school systems are planning for closures or delays later in the week. Some West Virginia and Ohio schools were considering a late start to school Wednesday because of forecast snow, according to WTRF in Wheeling, West Virginia.
