Issued at 500 PM AST TUE OCT 06 2015 000 WTNT31 KNHC 062038 TCPAT1 BULLETIN HURRICANE JOAQUIN ADVISORY NUMBER 37 NWS NATIONAL HURRICANE CENTER MIAMI FL AL112015 500 PM AST TUE OCT 06 2015 ...JOAQUIN RACING EAST-NORTHEASTWARD TOWARD COOLER WATERS... SUMMARY OF 500 PM AST...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...39.0N 56.9W ABOUT 565 MI...910 KM SSW OF CAPE RACE NEWFOUNDLAND MAXIMUM SUSTAINED WINDS...80 MPH...130 KM/H PRESENT MOVEMENT...ENE OR 70 DEGREES AT 23 MPH...37 KM/H MINIMUM CENTRAL PRESSURE...974 MB...28.77 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 PM AST (2100 UTC), the center of Hurricane Joaquin was located near latitude 39.0 North, longitude 56.9 West. Joaquin is moving toward the east-northeast near 23 mph (37 km/h), and this motion is expected to continue during the next 24 hours. Maximum sustained winds remain near 80 mph (130 km/h) with higher gusts. Some weakening is forecast during the next 48 hours, and Joaquin is expected to lose tropical characteristics on Wednesday. Hurricane force winds extend outward up to 45 miles (75 km) from the center and tropical storm force winds extend outward up to 275 miles (445 km). The estimated minimum central pressure is 974 mb (28.77 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Joaquin will continue to affect Bermuda during the next day or so. Swells are affecting much of the mid-Atlantic and northeast coast of the United States and are increasing along coastal areas of Atlantic Canada, 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 PM AST. $$ Forecaster Avila

Hurricane JOAQUIN Forecast Discussion Number 36

2015-10-06 16:43:26| National Hurricane Center (Atlantic)

Issued at 1100 AM AST TUE OCT 06 2015 000 WTNT41 KNHC 061443 TCDAT1 HURRICANE JOAQUIN DISCUSSION NUMBER 36 NWS NATIONAL HURRICANE CENTER MIAMI FL AL112015 1100 AM AST TUE OCT 06 2015 Joaquin is in a state of gradual decay. Although an eye feature is still occasionally visible, there has been some erosion of the inner-core deep convection. A series of microwaves images this morning indicate some eastward tilt of the vortex with height, and there is evidence of dry air entrainment into the inner core. Dvorak intensity estimates are slowly decreasing, and the initial wind speed is reduced to 70 kt. An increase in southwesterly shear and cooler waters along Joaquin's track should cause further weakening during the next few days. Cooler and drier air behind a low-level baroclinic zone currently draped to the north of the cyclone should gradually be advected into Joaquin's circulation during the next 24 to 48 hours, and extratropical transition is expected to be complete in about 36 hours. The new intensity forecast is near the multi-model consensus through 36 hours and then a bit above that after that time. Recent fixes indicate that Joaquin has is accelerating northeastward, and the initial motion estimate is 055/16. The cyclone is expected to further accelerate toward the east-northeast as it becomes fully embedded in a belt of nearly zonal middle- to upper-tropospheric flow during the next few days. After extratropical transition, Joaquin should experience a significant deceleration when it approaches the British Isles. The track guidance is tightly clustered through 48 hours, with somewhat greater spread after that time. The new track forecast is about the same as the previous one and lies near the multi-model consensus for the remainder of the forecast period.
