SUMMARY OF 500 AM AST...0900 UTC...INFORMATION ---------------------------------------------- LOCATION...40.5N 49.4W ABOUT 465 MI...750 KM SSE OF CAPE RACE NEWFOUNDLAND MAXIMUM SUSTAINED WINDS...75 MPH...120 KM/H PRESENT MOVEMENT...ENE OR 75 DEGREES AT 32 MPH...52 KM/H MINIMUM CENTRAL PRESSURE...977 MB...28.85 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 AM AST (0900 UTC), the center of Hurricane Joaquin was located near latitude 40.5 North, longitude 49.4 West. Joaquin is moving toward the east-northeast near 32 mph (52 km/h) and this motion is expected to continue through Friday. Maximum sustained winds have decreased to near 75 mph (120 km/h) with higher gusts, and additional weakening is forecast during the next 48 hours. Joaquin is expected to lose tropical characteristics by tomorrow evening, and to become a large extratropical cyclone by Thursday. Hurricane force winds extend outward up to 60 miles (95 km) from the center and tropical storm force winds extend outward up to 275 miles (445 km). The estimated minimum central pressure is 977 mb (28.85 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Joaquin will continue to affect Bermuda and Atlantic Canada during the next day or so. Swells affecting much of the eastern coast of the United States are now mostly associated with a non-tropical area of low pressure over the Western Atlantic, and these swells are expected to continue for the next day or two. Life-threatening surf and rip current conditions are likely in association with these swells. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 1100 AM AST. $$ Forecaster Beven

Issued at 500 AM AST WED OCT 07 2015000 WTNT41 KNHC 070832 TCDAT1 HURRICANE JOAQUIN DISCUSSION NUMBER 39 NWS NATIONAL HURRICANE CENTER MIAMI FL AL112015 500 AM AST WED OCT 07 2015 The organization of Joaquin continues to slowly decrease, with the central convection now present only in the northeastern semicircle. Satellite intensity estimates from TAFB and SAB are now 65 kt, and that is the advisory intensity. Joaquin is now moving over colder water north of the Gulf Stream, and the cyclone is gradually becoming embedded in a baroclinic zone. This combination should cause continued weakening and eventual extratropical transition. The current expectation is that the central convection will dissipate before the cyclone develops fronts, so the intensity forecast calls for Joaquin to become post-tropical for about 12 hours before becoming extratropical. The new intensity forecast shows a slightly faster weakening than the previous forecast, and calls for Joaquin or its remnants to dissipate by 120 hours. Joaquin continues moving rapidly east-northeastward as it is embedded in strong westerly flow north of the subtropical ridge. This motion should continued for another 36 hours or so. After that time, the guidance is now in better agreement that the cyclone should turn decelerate and turn east-southeastward as it comes under the influence of a developing deep-layer trough over western Europe. The new forecast track is an update of the previous track. The track, intensity, and wind radii forecasts for 24 hours and beyond are based upon guidance provided by the Ocean Prediction Center.
