There have been reports of 3-5" of rain in the New Bedford area already today as Hurricane Arthur races Northeast towards the Canadian Maritime. An additional 3-6+ inches of rain is likely in Bristol and Plymouth counties which will lead to a significant flooding event in that portion of the state.

That band of yellow and red along the S MA coast has been nearly stationary all afternoon. Flash Flood Watches are up for most of the state, with warnings in effect for the South Coast

The winds are not going to be a major deal outside of the Cape, but a few gusts over Tropical Storm force are possible across Eastern MA. Gusts up to 60 are possible in Nantucket/Outer Cape. The Upper Cape/Vineyard are looking at 45-55 in general. The major story will be the rain. The WPC has issued a precipitation discussion for Southeast New England and it is a not a pretty outlook

Basically a front is stalled out in Eastern MA. While this front contributed to keeping Arthur offshore, it is setting the stage for a flood event. Here is the local surface analysis

As I type this the NWS has upgraded to Major Flood Emergency in New Bedford. Flash flooding is likely in other areas as the rainfall rates increase. Do not drive through a flooded roadway. The rain ends around midnight west to east. Rest of the weekend is great.
