Batten down the hatches!

Northeast Flood Watch area (Intellicast)
This has been updating so it shows nothing now!
A coastal storm, which we have not seen since since late last year, will affect the region Sunday Afternoon into early Monday Afternoon. The storm system will bring much needed and beneficial rainfall, however, the rainfall may come in a relatively short period of time and this could result in urban and poor drainage flooding as well as flashier small stream flooding. Mainstem rivers should not experience any flood issues. Total rainfall of 2-4 inches are likely with isolated higher rainfall amounts possible.

Another concern with this system will be strong to damaging winds along the coastline. At this time, it is unclear how much wind will be brought down to the surface as winds just off the surface will be quite strong. It appears at least Wind Advisory criteria could be met over portions of East and South Coastal Massachusetts and Rhode Island and Cape Cod and the Islands. There is the possibility for even stronger winds if an inversion which could keep stronger winds just off the surface is broken. That would allow for stronger winds to reach portions of the area.
