Hurricane Idas remnants to bring torrential rain and possible flash flooding to Massachusetts, Thursday morning commute not looking too good – Boston…

Buckle up for yet another round of heavy rainfall and flooding.

Hurricane Idas remnants will be sweeping through Massachusetts late Wednesday into Thursday, bringing torrential rain and the potential for very significant flash flooding to the Bay State.

The entire state is now under a flash flood watch, according to the National Weather Service. Up to 6 inches of rain is possible.

The bulk of heavy rain should occur Wednesday night into Thursday morning, and theres a high confidence for 3 to 4 inches of rain around the Boston area with isolated higher amounts possible, said Frank Nocera, meteorologist at the National Weather Services Boston office.

There could definitely be some street and highway flooding, and small rivers and streams could overflow, he added. Stream levels are already high because of how wet its been this summer.

The heavy rainfall should still be around Thursday morning during rush hour. Some road closures are possible, Nocera said.

The Thursday morning commute is not looking too good, he added, saying that hydroplaning is a concern. It would definitely be a good day to telework.

The rain should move offshore around noon on Thursday, and the afternoon looks dry.

Along the coast, a gale watch is in effect from late Wednesday night through Thursday evening. Three- to five-foot seas are possible in Massachusetts coastal waters, the Nantucket Sound, Vineyard Sound and Buzzards Bay.

Strong winds can cause hazardous seas which could capsize or damage vessels and reduce visibility, the watch reads.

Mariners should consider altering plans to avoid possible hazardous conditions, the alert states. Remain in port, seek safe harbor, alter course, and/or secure the vessel for severe wind and seas.

A fall-like air mass is expected following the remnants of Ida, bringing cooler than normal temps. Thursday night temps could drop into the 50s.

Both Friday and Saturday should be in the low 70s, followed by mid 70s on Sunday, and then up to 80 on Labor Day. The holiday weekend looks to be dry and pleasant.
