TROPICAL CYCLONE 09L (ISAIAS) ***FINAL BULLETIN*** PUBLIC ADVISORY #16 FORCE THIRTEEN SINGAPORE, SINGAPORE 0150 UTC WED AUG 5 2020 ...ISAIAS LIKELY TO TRANSITION INTO A POST-TROPICAL CYCLONE... SUMMARY OF 0000 UTC...INFORMATION ----------------------------------- LOCATION...NEAR 43.6 N 73.0 W... MAXIMUM SUSTAINED WINDS...50MPH...80KM/H MINIMUM CENTRAL PRESSURE...997MB WATCHES AND WARNINGS ----------------------------------- A Tropical Storm Warning is in effect for... * Watch Hill Rhode Island to Stonington Maine * Martha's Vineyard, Nantucket, and Block Island
DISCUSSION ----------------------------------- NOAA Doppler radar data from Islip, New York (KOKX), indicated 70-kt winds just off the surface south of Long Island earlier this afternoon, along with buoy reports from New York Harbor Inlet (44065) that supported lowering the intensity to 55 kt. The motion remains north-northeastward or 020/35 kt. Isaias will continue moving north-northeastward through tonight, accompanied by a gradual decrease in forward speed. In 12 hours or, the cyclone is expected to interact with a larger extratropical over southeastern Canada and degenerate into a post-tropical cyclone near western Maine. By 24 hours, Isaias is expected to transition to an extratropical low, and dissipate or become absorbed by the aforementioned larger extratropical low. The new NHC track forecast is just an extension of the previous advisory, and lies very close to the tightly clustered consensus track models. Isaias will continue to gradually spin down and lose its tropical characteristics. The precipitation has decreased in size and also has become more stratiform in appearance, which are indications that the cyclone is gradually weakening. This downward trend should continue until Isais becomes an extratropical low in 12-24 hours.
