DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 100 AM CDT (0600 UTC), the center of Tropical Storm Hermine was located near latitude 26.0 North, longitude 87.0 West. Hermine has been moving slowly toward the north near 5 mph (9 km/h) during the past couple of hours, but should begin to move toward the north-northeast with an increase in forward speed soon. On the forecast track, the center will be near the Florida coast in the warning area Thursday night. Preliminary reports from the NOAA Hurricane Hunter aircraft indicate that maximum sustained winds remain near 60 mph (95 km/h) with higher gusts. Some strengthening is forecast during the next 24 to 36 hours, and Hermine is expected to be a hurricane by the time landfall occurs. Tropical-storm-force winds extend outward up to 125 miles (205 km) from the center. The minimum central pressure just reported by a NOAA Hurricane Hunter aircraft is 999 mb (29.50 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected to reach the coast within the warning area beginning Thursday night. Winds are expected to first reach tropical storm strength by Thursday afternoon, making outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. Tropical storm conditions are possible in the tropical storm watch area by 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. Persons located within these areas should take all necessary actions to protect life and property from rising water. Promptly follow any instructions, including evacuation orders, from local officials. The water could reach the following heights above ground if the peak surge occurs at the time of high tide... Destin to Indian Pass...1 to 3 feet Indian Pass to Chassahowitzka...4 to 7 feet Chassahowitzka to Aripeka...2 to 4 feet Aripeka to Bonita Beach...including Tampa Bay...1 to 3 feet Florida-Georgia line to Cape Fear...1 to 3 feet The Prototype National Weather Service Storm Surge Watch/Warning Graphic is a depiction of areas that would qualify for inclusion under a storm surge watch or warning currently under development by the National Weather Service and planned for operational use in 2017. This prototype graphic is available at www.hurricanes.gov/graphics_at4.shtml?wsurge RAINFALL: Hermine is expected to produce storm total rainfall amounts of 5 to 10 inches over portions of northwest Florida through Friday, with isolated maximum amounts of 20 inches possible. Rainfall totals of 4 to 8 inches are expected across portions of the southeastern United States from southeast Georgia, central to eastern South Carolina and eastern North Carolina, with local amounts of 10 inches possible through Saturday. These rains may cause life-threatening flash flooding. TORNADOES: A tornado or two is possible overnight near the central Florida coast. The tornado risk will increase through Thursday and spread into north Florida and southeast Georgia. NEXT ADVISORY ------------- Next complete advisory at 400 AM CDT. $$ Forecaster Avila
