DISCUSSION AND OUTLOOK ---------------------- At 1100 AM EDT (1500 UTC), the center of Tropical Storm Humberto was located near latitude 28.9 North, longitude 77.9 West. Humberto is moving toward the north near 7 mph (11 km/h), and this motion is expected to continue into tonight. A sharp turn to the northeast is forecast to occur Monday morning or afternoon, followed by a motion toward the northeast and east-northeast on Tuesday and Wednesday. On the forecast track, the center of Humberto will continue to move away from the Bahamas and remain well offshore of the east coast of Florida through Wednesday. Maximum sustained winds have increased to near 65 mph (100 km/h) with higher gusts. Additional strengthening is forecast through Wednesday, and Humberto is expected to become a hurricane by tonight. Tropical-storm-force winds extend outward up to 160 miles (260 km) from the center. The estimated minimum central pressure is 997 mb (29.44 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Gusty winds in squalls are still affecting portions of the northwestern Bahamas. These winds should subside later today. RAINFALL: Outer rain bands associated with Humberto are expected to produce additional rainfall of 1 to 2 inches in the central and northern Bahamas, with isolated storm total amounts of 6 inches. Humberto may bring periods of heavy rain to Bermuda beginning late Wednesday. SURF: Swells generated by Humberto will affect the northwestern Bahamas, and the southeastern coast of the United States from east-central Florida to North Carolina during the next few days. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 500 PM EDT. $$ Forecaster Stewart |
