DISCUSSION AND OUTLOOK ---------------------- At 100 AM EST (0600 UTC), the center of Tropical Storm Nicole was located near latitude 26.9 North, longitude 75.4 West. Nicole is moving toward the west-southwest near 11 mph (18 km/h). A west-southwestward to westward motion is expected through today. A west-northwestward motion is forecast to begin tonight, followed by a turn toward the northwest and north on Thursday and Thursday night. On the forecast track, the center of Nicole will approach the northwestern Bahamas this morning, move near or over those islands by this afternoon, and approach the east coast of Florida within the hurricane warning area tonight or early Thursday. Nicole's center is then expected to move across central and northern Florida into southern Georgia Thursday and Thursday night. Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Some strengthening is expected during the next day or so, and Nicole is forecast to become a hurricane later today and remain a hurricane when it reaches the east coast of Florida. Tropical-storm-force winds extend outward up to 380 miles (610 km) from the center. Data from an Air Force Reserve Hurricane Hunter aircraft indicate that the minimum central pressure is 985 mb (29.09 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: Tropical storm conditions are beginning across the northwestern Bahamas, and hurricane conditions are expected within the hurricane warning area later today. Tropical storm conditions are also beginning along portions of the east coast of Florida, and hurricane conditions are expected within the hurricane warning area tonight or Thursday morning. Hurricane conditions are possible within the hurricane watch area tonight and Thursday. Tropical storm conditions are possible within the watch area along the west coast of Florida by tonight. 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 Florida to Altamaha Sound Georgia including the St. Johns River to the Fuller Warren Bridge...3 to 5 ft * Altamaha Sound Georgia to the South Santee River South Carolina...2 to 4 ft * St. Johns River south of the Fuller Warren Bridge to Georgetown Florida...2 to 4 ft * Hallandale Beach to North Palm Beach...2 to 4 ft * Anclote River to Indian Pass...2 to 4 ft * Englewood to Anclote River including Tampa Bay...1 to 3 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 Friday: Northwest Bahamas into the eastern, central and northern portions of the Florida Peninsula: 3 to 5 inches with local maxima of 8 inches. Southeast into the southern and central Appalachians, western Mid Atlantic, and eastern portions of Tennessee, Kentucky, and Ohio: 2 to 4 inches with local maxima of 6 inches along the Blue Ridge. Flash and urban flooding will be likely, along with possible renewed river rises on the St. Johns River, across the Florida Peninsula on Wednesday and Thursday. Heavy rainfall from this system will spread north farther up the Eastern Seaboard late Thursday into Friday. TORNADOES: Isolated tornadoes will be possible from eastern Florida into parts of eastern Georgia and eastern South Carolina beginning late tonight and continuing through Friday. SURF: Large swells generated by Nicole will affect the northwestern 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.
