A storm system on Saturday brought heavy rain to the Northeast and heavy snow to parts of New England and Northern New York, leaving more than 300,000 households in several states without electricity.
More than 194,000 electricity customers in Maine, more than 71,000 customers in New Hampshire and more than 78,000 in New York State had lost power as of early Sunday morning, according to PowerOutage.us, a website that tracks power failures.
In New York City, the heavy rain and snow cleared overnight, according to the National Weather Service. But a flood advisory for parts of New Jersey and New York City was in effect until 5 a.m.
A flood warning had also been issued for Warren County, N.J., until 8:30 a.m. Such a warning, a higher level than an advisory, means that flooding is imminent or occurring.
The outages and weather notices followed a day of heavy precipitation across the region.
In Central Park, 3.63 inches of rain had fallen as of 5 p.m. Saturday, said David Stark, a meteorologist with the Weather Service Office in New York. Corinth, N.Y., reported over 20 inches of snow by Saturday night, according to the National Weather Service.
Philadelphia had 3.06 inches of rain, the wettest calendar day ever recorded in March in the official observing station since 1872, according to the National Weather Service office in Mount Holly, Pa.
The previous daily record for March 23 was 1.36 inches in 2005. For the month of March, the record was 2.79 inches, set on March 15, 1912, the Weather Service said.
Some areas across New England were hit with heavy snowfall.
Snow started falling in Vermont on Friday, with areas of higher elevation in Windsor and Rutland Counties recording 10 to 17 inches of snow as of Saturday afternoon, said Rebecca Duell, a meteorologist with the Weather Service in Burlington, Vt.
By 8:30 p.m. on Saturday, Landgrove, Vt., had reported almost 25 inches of snow, according to the National Weather Service.
Shrewsbury, Vt., reported 19.3 inches of snow. The city of Burlington had about six inches of snow as of Saturday afternoon, Ms. Duell said.
Other parts of the New England also had heavy snowfall. Lovell, Maine, had 13.5 inches and Waterville Valley, N.H., had 17.6 inches, according the Weather Service.
Albany, N.Y., recorded about 2.5 inches of snow as of Saturday afternoon. More than 50 miles north, the Glens Falls area had up to 15 inches of snow as of 2 p.m. on Saturday, said Brian Frugis, a meteorologist for the local Weather Service office. Wilton, N.Y., 43 miles north of Albany, had 18 inches of snowfall.
The region also experienced freezing rain, which caused some branches to fall, leading to power outages in the area, he said.
Separately, a system moving into the Western United States on Saturday was bringing snow from the northern High Plains through the Dakotas, Minnesota and parts of the upper Great Lakes.
Heavy snow was expected to spread from central and eastern Montana into the North Plains and upper Midwest on Sunday, continuing into Monday. Most of those areas were expected to get six to 12 inches of snow.
One to two feet of snow was forecast in portions of eastern North and South Dakota into western and central Minnesota, said Rich Otto, a meteorologist at the Weather Prediction Center in College Park, Md.
Heavy snow and gusty winds — as high as 50 miles per hour — in the Central and Southern Plains were also expected to create hazardous driving conditions late on Saturday and into the early part of the week.
