Tropical Storm Jose Local Statement Advisory Number 61 MAZ022>024-RIZ008-202330- Tropical Storm Jose Local Statement Advisory Number 61 National Weather Service Taunton MA AL122017 1130 AM EDT Wed Sep 20 2017 This product covers Southern New England **Prolonged effects from Jose expected over Cape Cod and Nantucket** NEW INFORMATION --------------- * CHANGES TO WATCHES AND WARNINGS: - None * CURRENT WATCHES AND WARNINGS: - A Tropical Storm Warning is in effect for Barnstable MA, Block Island RI, Dukes MA, and Nantucket MA * STORM INFORMATION: - About 150 miles south of Nantucket MA - 39.0N 70.0W - Storm Intensity 70 mph - Movement Northeast or 35 degrees at 8 mph SITUATION OVERVIEW ------------------ Tropical Storm Jose has strengthened slightly. It is passing well south of Nantucket but the main message here is that it is forecast to slow down and stall over the next several days. It may even retrograde to the west a bit. This will likely keep a prolonged period of strong winds and severe beach erosion over southeastern New England, especially Cape Cod and Nantucket, right through Friday. Minor to moderate coastal flooding is possible, especially on Nantucket late tonight through Thursday night. Minor coastal flooding is still possible on Friday. Bands of locally heavy rain will continue to impact Cape Cod and the Islands into Thursday morning. Rainfall totals of up to 4 inches are possible on Nantucket. Wind gusts were 30 to 40 mph late this morning along the south coasts of Rhode Island and Massachusetts. Gusts up to to 60 mph are possible on Nantucket with 45 to 55 mph on Cape Cod, Martha`s Vineyard and Block Island late this afternoon and on Thursday. On the coastal waters south and southeast of New England, seas will be 20 to 25 feet. The combination of high seas and strong winds will result in life-threatening conditions. POTENTIAL IMPACTS ----------------- * SURGE: Protect against locally hazardous surge having possible limited impacts across Cape Cod and Nantucket. At Nantucket Harbor, the biggest concerns are the Thursday late morning and Thursday late night high tides. Potential impacts in these areas include: - Localized inundation with storm surge flooding mainly along immediate shorelines and in low-lying spots, or in areas farther inland near where higher surge waters move ashore. - Sections of near-shore roads and parking lots become overspread with surge water. Driving conditions dangerous in places where surge water covers the road. - Severe beach erosion. Heavy surf also breaching dunes, mainly in usually vulnerable locations. Strong rip currents. - Minor to locally moderate damage to marinas, docks, boardwalks, and piers. A few small craft broken away from moorings. * OTHER COASTAL HAZARDS: Jose will bring large waves, possibly 15 to 20 feet, to ocean exposed beaches across southeast Massachusetts. Severe beach erosion will occur. Some protective dunes may be at risk of being overtopped or eroded away. Dangerous rip currents will occur at the beaches. With Jose forecast to stall just southeast of the region, the threat of beach erosion and rip currents will be prolonged, likely lasting through the upcoming weekend and perhaps even into early next week. * WIND: Protect against hazardous wind having possible limited impacts across Cape Cod and the Islands, and Nantucket in particular. These winds will likely linger into Friday. Potential impacts in this area include: - Possible tree limbs broken off with some trees uprooted. - Some roads impassable from large debris, and more within heavily wooded places. - Scattered power and communications outages. * FLOODING RAIN: Protect against locally hazardous rainfall flooding having possible limited impacts across Nantucket and possibly Cape Cod. Potential impacts include: - Flood waters can enter a few structures, especially in usually vulnerable spots. A few places where rapid ponding of water occurs at underpasses, low-lying spots, and poor drainage areas. Some brief road closures. - Although unlikely, localized rainfall flooding could prompt a few evacuations. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Be prepared to follow any local instructions from emergency management officials. * OTHER PREPAREDNESS INFORMATION: All mariners should be in port and boat owners should have ensured that boats are moored very securely or removed from the water. Closely monitor NOAA Weather Radio or other local news outlets for official storm information. Listen for possible changes to the forecast. * ADDITIONAL SOURCES OF INFORMATION: - For information on appropriate preparations see ready.gov - For information on creating an emergency plan see getagameplan.org - For additional disaster preparedness information see redcross.org NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in Taunton MA around 6 PM EDT, or sooner if conditions warrant.
