Post-Tropical Cyclone Humberto Public Advisory Number 30
2019-09-20 04:48:38| National Hurricane Center (Atlantic)
Issued at 1100 PM AST Thu Sep 19 2019 000 WTNT34 KNHC 200248 TCPAT4 BULLETIN Post-Tropical Cyclone Humberto Advisory Number 30 NWS National Hurricane Center Miami FL AL092019 1100 PM AST Thu Sep 19 2019 ...HUMBERTO BECOMES AN EXTRATROPICAL CYCLONE... ...THIS IS THE LAST ADVISORY... SUMMARY OF 1100 PM AST...0300 UTC...INFORMATION ----------------------------------------------- LOCATION...40.0N 58.0W ABOUT 525 MI...845 KM SSW OF CAPE RACE NEWFOUNDLAND MAXIMUM SUSTAINED WINDS...100 MPH...155 KM/H PRESENT MOVEMENT...NNE OR 30 DEGREES AT 20 MPH...31 KM/H MINIMUM CENTRAL PRESSURE...965 MB...28.50 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Post-Tropical Cyclone Humberto was located near latitude 40.0 North, longitude 58.0 West. The post-tropical cyclone is moving toward the north-northeast near 20 mph (31 km/h). A slower north-northeastward motion is expected tonight and Friday. A turn toward the east-northeast is expected to commence by Friday night. Maximum sustained winds are near 100 mph (155 km/h) with higher gusts. Gradual weakening is expected during the next couple of days. Hurricane-force winds extend outward up to 80 miles (130 km) from the center and tropical-storm-force winds extend outward up to 380 miles (610 km). The estimated minimum central pressure is 965 mb (28.50 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Large swells and dangerous surf generated by Humberto will continue along the coast of Bermuda during the next day or two, and these could continue to cause coastal flooding. Swells will continue to affect the northwestern Bahamas and much of the coast of the United States from east-central Florida to the Mid-Atlantic States during the next couple of days. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office and the Bermuda Weather Service. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on this system. Additional information on this system can be found in High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php $$ Forecaster Pasch
