Amazing spring-time storm. First take a look at this visible satellite picture of the storm. This is courtesy of NOAA.
You can make out the classic comma-shape to the storm. In addition, you can see a swirl of clouds into the center of the circulation — even an eye-like feature near the center. The system continues to undergo the “bombogenesis” process — that’s where the central pressure drops at least 24mb in 24 hours. This storm has nearly doubled that! At 8am, the central pressure was nearly 965mb. In comparison, Hurricane Bob was 964mb when it blew through Newport, back in 1991!!!
Due to the very low pressure associated with this storm, we are seeing some very strong wind gusts. In Rhode Island, TF Green Airport had a gust to 51mph this morning. In Massachusetts, Nantucket had a gust of 83mph!
Even though the storm will be pulling away from Southern New England this afternoon, we will still see some very strong wind gusts into the evening.
A Wind Advisory is in effect until 8pm for our area. We could see gusts to 50mph from the north to northwest through the afternoon into mid-eveing. A High Wind Warning is in effect for eastern Massachusetts where north and northwest winds could gust to 75mph (some isolated gusts in excess of 80mph are certainly possible).
These winds are certainly powerful enough to cause property damage and power outages. In fact, hundreds were without power this morning on the Cape and Nantucket. Isolated outages were reported in Rhode Island.
Here is a computer model representation of wind gusts at noon.
According to this computer model (RPM), the winds could still be gusting to near hurricane force on Nantucket at noon!
The winds will diminish to about 10-15mph overnight….and should continue to be light tomorrow.
