Nor'easter No. 4 NH Update: A Dusting To 6 Inches

GRAY, ME — While with worst of Winter Storm Toby is expected to miss most of New Hampshire, the Granite State will receive as much as six inches of snow in some communities in the lower part of the state, according to weather forecasters. The National Weather Service has issued both winter weather and coastal flood advisories for most of the communities south of Manchester. Alerts were updated by the NWS at around 2 p.m. on March 21, 2018.

“Low pressure well south of Nantucket Island today will move northeast tonight,” according to the alert. “This will allow for snow to enter southernmost areas in Maine and southeastern New Hampshire. The snow will end from west to east Thursday morning as the low tracks towards the Canadian Maritimes.”

Prepare for a slippery commute on Thursday morning and reduced visibilities at times, according to the alert.

The latest snowfall estimates, posted on Wednesday morning, are expected to run from two to three inches in Concord, to three to four inches in Bedford, Amherst, Exeter, Londonderry, Merrimack, Milford, and Portsmouth, to three to six inches to Nashua, Salem, and Windham.

The snow is expected to start around 6 p.m. in Nashua, Salem, and Windham, around 7 p.m. in the rest of the southern tier of the state, and then around 9 p.m. in Concord. The storm is expected to end at around 9 a.m. on Thursday.

NWS forecasters also issued flooding alerts for the Seacoast.

“A tidal anomaly at close to a half foot and an additional two foot storm surge are expected tonight near the time of high tide,” according to the alert. “This will combine with building nearshore waves of 10 to 15 feet to produce generally minor beach erosion and splash-over flooding near the time of high tide tonight. Pockets of moderate impacts are possible, due in part to the damage of sand dunes and infrastructure from the storms earlier this month.”

Residents along the Seacoast should be prepared for “astronomical tides peak out, as well tonight,” with flooding in the Backbay area of Hampton and some streets in Portsmouth may have minor flooding.

“Areas that have splash-over will have also some flooding due to the pooling of water landward of the dunes,” according to the alert.
