A Storm Surge Warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline, in the indicated locations. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. 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. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours.

DISCUSSION AND OUTLOOK ---------------------- At 100 AM EST (0600 UTC), the center of Subtropical Storm Nicole was located by an Air Force Reserve Hurricane Hunter aircraft near latitude 27.3 North, longitude 71.2 West. Nicole is moving toward the northwest near 7 mph (11 km/h). A turn toward the west or west-southwest is forecast to begin today, and that motion should continue through early Thursday. On the forecast track, the center of Nicole will approach the northwestern Bahamas today and tonight, move near or over those islands on Wednesday, and approach the east coast of Florida Wednesday night. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Some strengthening is expected today and on Wednesday. Nicole is forecast to be at or near 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 310 miles (500 km) from the center. Data from NOAA buoy 41047 indicate that the minimum central pressure is 998 mb (29.47 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 expected in the northwest Bahamas within the hurricane warning area by early Wednesday, with tropical storm conditions expected elsewhere in the northwest Bahamas by tonight. Hurricane conditions are possible within the watch area in Florida by Wednesday night with tropical storm conditions possible by tonight or early Wednesday. 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 * St. Johns River south of the Fuller Warren Bridge to Georgetown...2 to 4 ft * Hallandale Beach to North Palm Beach...2 to 4 ft * North of Ocean Reef to Hallandale Beach including Biscayne Bay...1 to 2 ft Storm surge could raise water levels by as much as 4 to 6 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: Northwest Bahamas, central and northern portions of the Florida Peninsula: 3 to 5 inches with local maxima of 7 inches. Southeast Florida and Southeast Georgia: 1 to 3 inches with local maxima of 5 inches. Heavy rainfall from this system will spread north farther up the Eastern Seaboard late this week into this weekend. SURF: Large swells generated by Nicole will affect the northwest Bahamas, the east coast of Florida, and much of the southeastern United States coast during the next several days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
