Hurricane Isaac Public Advisory Number 8
2024-09-27 22:34:31| National Hurricane Center (Atlantic)
Issued at 500 PM AST Fri Sep 27 2024 000 WTNT35 KNHC 272034 TCPAT5 BULLETIN Hurricane Isaac Advisory Number 8 NWS National Hurricane Center Miami FL AL102024 500 PM AST Fri Sep 27 2024 ...ISAAC IS INTENSIFYING... SUMMARY OF 500 PM AST...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...37.8N 45.3W ABOUT 995 MI...1600 KM W OF THE AZORES MAXIMUM SUSTAINED WINDS...85 MPH...140 KM/H PRESENT MOVEMENT...E OR 80 DEGREES AT 16 MPH...26 KM/H MINIMUM CENTRAL PRESSURE...976 MB...28.82 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 500 PM AST (2100 UTC), the center of Hurricane Isaac was located near latitude 37.8 North, longitude 45.3 West. Isaac is moving toward the east near 16 mph (26 km/h). A gradual turn to the east-northeast is expected with a slight decrease in forward speed over the next day or so. On Saturday, a gradual turn to the northeast is forecast and this motion should continue through Monday. Maximum sustained winds have increased to near 85 mph (140 km/h) with higher gusts. Some slight additional strengthening is expected tonight or Saturday morning followed by gradual weakening through early next week. Isaac is expected to be a post-tropical cyclone on Monday. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 90 miles (150 km). The estimated minimum central pressure is 976 mb (28.82 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Isaac and a large wind fetch from a deep-layer trough could spread into the Azores by this weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 1100 PM AST. $$ Forecaster Bucci/Rosado
