DISCUSSION AND OUTLOOK ---------------------- At 500 PM EDT (2100 UTC), the center of Hurricane Humberto was located near latitude 31.0 North, longitude 72.3 West. Humberto is moving toward the east-northeast near 12 mph (19 km/h), and this general motion with a gradual increase in forward speed is expected through early Thursday, followed by a northeastward motion through Friday. On the forecast track, the center of Humberto is expected to pass just to the northwest and north of Bermuda Wednesday night. Maximum sustained winds are near 105 mph (165 km/h) with higher gusts. Additional strengthening is forecast during the next 36 hours, and Humberto could become a major hurricane late tonight or on Wednesday. Humberto is a large hurricane. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km). The estimated minimum central pressure is 960 mb (28.35 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected to reach Bermuda by Wednesday night and continue into early Thursday morning. Winds are expected to first reach tropical-storm strength by Wednesday afternoon, making outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. RAINFALL: Humberto may bring periods of heavy rain to Bermuda beginning Tuesday, with rainfall accumulations of 2 to 4 inches and isolated maximum amounts near 6 inches expected. SURF: Large swells generated by Humberto will increase along the coast of Bermuda by Wednesday. Dangerous breaking waves, especially along south-facing beaches, will be possible Wednesday night into Thursday, and could cause coastal flooding. Swells will continue to affect the northwestern Bahamas and the southeastern coast of the United States from east-central Florida to North Carolina 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. STORM SURGE: Storm surge and wave setup could raise water levels by 1 to 3 feet above normal tide levels along the immediate southern coast of Bermuda.
