DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 700 PM CDT (0000 UTC), the center of Tropical Depression Nine was located near latitude 24.2 North, longitude 87.7 West. The depression is moving toward the west-northwest near 5 mph (7 km/h). A turn toward the north-northwest is expected tonight, followed by a turn toward the north-northeast on Wednesday. On the forecast track, the center will approach the northwest Florida coast in the watch area on Thursday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Some strengthening is forecast during the next 48 hours, and the depression is expected to become a tropical storm tonight or early Wednesday. The minimum central pressure recently reported by a NOAA Hurricane Hunter aircraft was 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are possible over portions of the Hurricane Watch area by Thursday afternoon. Tropical storm conditions are possible over portions of the Tropical Storm Watch area by Thursday afternoon. 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 possibility of life-threatening inundation within the next 48 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 be prepared to take all necessary actions to protect life and property from rising water. Promptly follow any instructions from local officials. The water could reach the following heights above ground if the peak surge occurs at the time of high tide... Indian Pass to Aripeka...2 to 4 feet Aripeka to Bonita Beach...including Tampa Bay...1 to 2 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: The depression is expected to produce additional rain accumulations of 3 to 5 inches over western Cuba through Wednesday, with maximum storm total amounts up to 20 inches. These rains could cause life-threatening flash floods and mud slides. Storm total rainfall amounts of 5 to 10 inches are possible over much of the Florida peninsula through Friday morning, with isolated maximum amounts of 15 inches possible. This rainfall may cause flooding and flash flooding. NEXT ADVISORY ------------- Next complete advisory at 1000 PM CDT. $$ Forecaster Stewart NNNN
