Tropical Storm Jose Public Advisory Number 60A
2017-09-20 13:44:37| National Hurricane Center (Atlantic)
Issued at 800 AM EDT Wed Sep 20 2017 000 WTNT32 KNHC 201144 TCPAT2 BULLETIN Tropical Storm Jose Intermediate Advisory Number 60A NWS National Hurricane Center Miami FL AL122017 800 AM EDT Wed Sep 20 2017 ...JOSE CONTINUES TO PRODUCE DANGEROUS SURF AND RIP CURRENTS ALONG A LARGE PORTION OF THE U.S. EAST COAST... SUMMARY OF 800 AM EDT...1200 UTC...INFORMATION ---------------------------------------------- LOCATION...38.8N 70.2W ABOUT 165 MI...265 KM S OF NANTUCKET MASSACHUSETTS MAXIMUM SUSTAINED WINDS...65 MPH...100 KM/H PRESENT MOVEMENT...NE OR 40 DEGREES AT 8 MPH...13 KM/H MINIMUM CENTRAL PRESSURE...976 MB...28.82 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Woods Hole to Sagamore Beach, including Cape Cod * Block Island * Martha's Vineyard * Nantucket A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within the next 12 to 24 hours. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 800 AM EDT (1200 UTC), the center of Tropical Storm Jose was located near latitude 38.8 North, longitude 70.2 West. Jose is moving toward the northeast near 8 mph (13 km/h), and this general motion with a decrease in forward speed is expected to continue through tonight. On the forecast track, the center of Jose is expected to pass well to the east of the New Jersey coast today, and pass offshore of southeastern Massachusetts on Thursday. Maximum sustained winds are near 65 mph (100 km/h) with higher gusts. Gradual weakening is forecast during the next couple of days. Tropical-storm-force winds extend outward up to 230 miles (370 km) from the center. The minimum central pressure based on Air Force reconnaissance aircraft data is 976 mb (28.82 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected to begin in the warning area later today. SURF: Swells generated by Jose are affecting Bermuda and much of the U.S. east coast. These swells are likely to cause dangerous surf and rip current conditions during the next several days in these areas. For more information, please consult products from your local weather office. RAINFALL: Jose is expected to produce the following additional rainfall accumulations through Thursday: Martha's Vineyard and Cape Cod...1 to 2 inches. Nantucket...2 to 4 inches. These rainfall totals could cause isolated flash flooding. NEXT ADVISORY ------------- Next complete advisory at 1100 AM EDT. $$ Forecaster Cangialosi

Tropical Storm Jose Forecast Discussion Number 60
2017-09-20 10:42:21| National Hurricane Center (Atlantic)
Issued at 500 AM EDT Wed Sep 20 2017 000 WTNT42 KNHC 200842 TCDAT2 Tropical Storm Jose Discussion Number 60 NWS National Hurricane Center Miami FL AL122017 500 AM EDT Wed Sep 20 2017 Enhanced BD-curve infrared imagery shows considerable decay of yesterday afternoon's burst of deep convection near Jose's center. An earlier GPM low-frequency microwave overpass revealed that the strongest convection and associated winds were located in the north and west periphery of of the cyclone's circulation, a wind pattern indicative of non-tropical systems. Based on the deteriorating cloud pattern and a blend of the latest subjective T-numbers from TAFB and SAB, the initial intensity is lowered to 55 kt. Jose has begun its movement north of the Gulf Stream's north wall and over decreasing oceanic temperatures. Subsequent CIMSS shear analysis and the SHIPS model indicate modest southwesterly shear undercutting the outflow aloft. These inhibiting factors should result in additional weakening, and the official forecast calls for Jose to become a post-tropical cyclone in 48 hours, if not sooner. The initial motion is estimated to be northeastward, or 040/7 kt. There is no significant change to the previous track forecast or philosophy. The large-scale models continue to agree on Jose decreasing in forward speed and gradually turning toward the east on Thursday morning in response to a mid-tropospheric shortwave trough moving eastward out of the eastern Canadian provinces. Through the remainder of the forecast period, high pressure is expected to build over the northeast U.S. and adjacent waters, causing Jose to drift southward and southwestward through the 72 hour period. After that time, the cyclone is expected to basically meander in the northwest Atlantic within the weak steering flow produced by the aforementioned high pressure to the northwest of the cyclone and a building mid-level ridge to the southeast. The NHC forecast a little slower at days 4 and 5 and closely follows the GFS/ECMWF (GFEX) consensus and the forecast input from NOAA Ocean Prediction Center. KEY MESSAGES: 1. While the center of Jose is forecast to remain offshore of the U.S. east coast, the large cyclone is expected to cause some direct impacts in portions of New England, and a tropical storm warning is in effect for Cape Cod, Block Island, Martha's Vineyard, and Nantucket. 2. Minor to moderate coastal flooding is possible from Delaware to southern New England during the next several days. Please see products issued by local National Weather Service forecast offices. 3. Swells generated by Jose are affecting Bermuda, the Bahamas, and much of the U.S. east coast. These swells are likely to cause dangerous surf and rip current conditions for the next several days in these areas. 4. Jose is expected to produce additional rainfall accumulations of 1 to 2 inches over Martha's Vineyard and Cape Cod, and 2 to 4 inches in Nantucket as it passes offshore today into Thursday. This rainfall could cause isolated flash flooding.
