Good Morning Everyone,

We have increased the forecast wind gusts for this afternoon and this evening near the coast.
As a result, the following changes have been made:
  • Wind Advisory expanded to include coastal Plymouth County and Martha's Vineyard.
  • Storm Warning issued for Nantucket Sound and the outer coastal waters from Provincetown to Nantucket and Martha's Vineyard.
Confidence remains high that a wind shift to the northeast will occur between 1 PM and 5 PM, accompanied by a burst of strong winds and a temperature drop into the 50s over the coastal waters and from coastal Plymouth County to Cape Cod and the Islands. 

Since this is the start of the holiday weekend, many recreational boaters may be caught off guard by the sudden increase in wind gusts and rapidly building seas.

Here are the details:

Coastal Plymouth County, Cape Cod, Martha's Vineyard, and Nantucket:
  • A Wind Advisory is in effect until 9 PM. 
  • Wind gusts of up to 50 mph expected, especially between 3 and 7 PM.
  • Minor wind damage, such as a few downed branches, may occur. 
Coastal Waters:
  • Storm Warnings issued for Nantucket Sound and the outer coastal waters from Provincetown to Nantucket and Martha's Vineyard. Gusts of 45 to 50 knots are expected, especially between 3 and 7 PM. Gusts will fall below Gale Force after 9 PM.
  • Gale Warnings remain posted for most of the Massachusetts and Rhode island coastal waters through early tonight. Wind gusts of up to 40 knots are expected.
  • A rapid wind shift to the northeast and burst of strong wind gusts will first occur around 1 PM off  Cape Ann and will reach the waters adjacent to Cape Cod and the Islands between 3 PM and 5 PM.
Graphics showing the latest forecasts of maximum wind gusts and maximum wave heights are attached.
