DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 400 PM CDT (2100 UTC), the center of Tropical Storm Hermine was located near latitude 25.5 North, longitude 87.4 West. Hermine is moving toward the north-northeast near 7 mph (11 km/h), and this motion with an increase in forward speed is expected to continue through Thursday. On the forecast track, the center will be near the coast in the warning area Thursday night. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Additional strengthening is forecast during the next 36 hours, and Hermine could be near hurricane strength by the time landfall occurs. Tropical-storm-force winds extend outward up to 125 miles (205 km) from the center, mainly to the east and southeast. The minimum central pressure reported by a NOAA Hurricane Hunter aircraft is 1004 mb (29.65 inches).

Hurricane conditions are possible over portions of the hurricane watch area beginning Thursday afternoon. Tropical storm conditions are possible in the tropical storm watch area by early Friday. 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. There is a danger of life-threatening inundation within the next 36 hours along the Gulf coast of Florida from Aripeka to Indian Pass. For a depiction of areas at risk, please see the Prototype National Weather Service Storm Surge Watch/Warning Graphic.
