A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Interests in the central Bahamas, the remainder of Florida, and along the southeastern coast of the United States should monitor the progress of Nicole. Additional watches will likely be required later today. For storm information specific to your area in the United States, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. For storm information specific to your area outside of the United States, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the center of Subtropical Storm Nicole was located near latitude 26.3 North, longitude 69.6 West. The storm is moving toward the northwest near 9 mph (15 km/h). This motion with a decrease in forward speed is expected later today. A turn westward or west-southwestward is then forecast Tuesday through early Thursday. On the forecast track, the center of Nicole will approach the northwestern Bahamas on Tuesday, move near or over those islands on Wednesday, and approach the east coast of Florida by Wednesday night. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Gradual strengthening is forecast during the next few days, and Nicole is forecast to be at hurricane intensity by Wednesday or Wednesday night while it is moving near or over the northwestern Bahamas. Winds of 40 mph extend outward up to 275 miles (445 km) from the center. The estimated minimum central pressure is 1002 mb (29.59 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Nicole can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2, WMO header WTNT42 KNHC, and on the web at www.hurricanes.gov/text/MIATCDAT2.shtml. WIND: Hurricane conditions are possible within the watch area in the northwest Bahamas by early Wednesday, with tropical storm conditions possible by Tuesday night. Hurricane conditions are possible within the watch area in Florida by Wednesday night with tropical storm conditions possible by Tuesday night. STORM SURGE: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... *North Palm Beach to Altamaha Sound including the St. Johns River to the Fuller Warren Bridge... 3 to 5 ft *Hallendale Beach to North Palm Beach...2 to 4 ft *North of Ocean Reef to Hallendale Beach including Biscayne Bay...1 to 2 ft Storm surge could raise water levels by as much as 3 to 5 feet above normal tide levels along the immediate coast of the northwestern Bahamas in areas of onshore winds. The deepest water will occur along the immediate coast near and to the north of the landfall location, where the surge will be accompanied by large and destructive waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. RAINFALL: Nicole is expected to produce the following rainfall amounts through Thursday: Across the northwest Bahamas, and the central and northern portions of the Florida Peninsula: 2 to 4 inches, with local maxima of 6 inches Heavy rainfall from this system will spread north across the Southeast United States late this week.
