Tropical Cyclone Statement issued September 26 at 11:30PM EDT by NWS Tallahassee FL HLSTAE This product covers eastern Florida panhandle, Florida Big Bend, southeastern Alabama and southwestern Georgia **HURRICANE CONDITIONS TO SPREAD NORTH OVERNIGHT ALONG THE I-75 CORRIDOR OF SOUTH GEORGIA. THIS IS THE TIME TO HUNKER DOWN.** NEW INFORMATION --------------- * CHANGES TO WATCHES AND WARNINGS: - None * CURRENT WATCHES AND WARNINGS: - A Storm Surge Warning and Hurricane Warning are in effect for Coastal Dixie, Coastal Franklin, Coastal Gulf, Coastal Jefferson, Coastal Taylor, Coastal Wakulla, Inland Dixie, Inland Jefferson, Inland Taylor, and Inland Wakulla - A Hurricane Warning is in effect for Baker, Ben Hill, Berrien, Brooks, Calhoun, Clay, Colquitt, Cook, Decatur, Dougherty, Early, Gadsden, Grady, Inland Franklin, Inland Gulf, Irwin, Lafayette, Lanier, Lee, Leon, Liberty, Lowndes, Madison, Miller, Mitchell, Quitman, Randolph, Seminole, Terrell, Thomas, Tift, Turner, and Worth - A Tropical Storm Warning is in effect for Calhoun, Central Walton, Coastal Bay, Coffee, Dale, Geneva, Henry, Holmes, Houston, Inland Bay, Jackson, North Walton, South Walton, and Washington * STORM INFORMATION: - About 10 miles south-southeast of Aucilla River or about 80 miles south-southwest of Valdosta - 29.9N 83.9W - Storm Intensity 140 mph - Movement North-northeast or 15 degrees at 24 mph SITUATION OVERVIEW ------------------ At 11 PM EDT, the center of Major Hurricane Helene was making landfall along the coast of Taylor County. This is the time for folks across the Big Bend of Florida and in Southwest Georgia to hunker down and stay safe. Early this evening around 7 pm, an offshore buoy in the left eyewall measured a 102 mph gust. Between 10 and 11 pm, multiple observations have indicated gusts to 84 mph along the Dixie and Taylor County coasts. At 1115 pm EDT, the Perry Airport measured a gust of 99 mph. Helene is a large hurricane, and tropical-storm force winds extend hundreds of miles out from the center. If an Extreme Wind Warning is issued for your location, that indicates the possibility of winds exceeding 115 mph. Shelter in an interior room of your building, similar to how you would treat a tornado. Stay away from windows. Remain sheltered until the eye-wall passes. At 11 pm EDT, Helene was quickly moving to the north-northeast at 24 mph. Helene will still be a damaging hurricane while moving north through the Big Bend region of Florida, and along the I-75 corridor of Georgia during the overnight hours. Catastrophic impacts are expected across our region from high winds, catastrophic and life-threatening storm surge on the coast of Apalachee Bay, and considerable to catastrophic flash flooding from heavy rainfall. A few tornadoes are possible as Helene moves through. Wind Threat: Significant to catastrophic wind damage is expected from the Big Bend of Florida up the I-75 corridor of South Georgia through the pre-dawn hours of Friday morning. Widespread and prolonged power outages, damage to critical infrastructure, catastrophic damage to the trees and powerlines, widespread inaccessibility due to blocked roads, and damage to well-built structures will all be likely, particularly close to and east of the track. Power outages will likely last days, if not weeks. Due to the quick forward speed and large size of Helene, significant wind damage will extend well north into Georgia. Surge Threat: At 11 pm EDT, a tide gage at Cedar Key, located along the Levy County coast, measured a tide level corresponding with 7 to 8 feet of inundation. Storm surge will increase quickly late this evening and early overnight along the coasts of Dixie, Taylor, Jefferson, and Wakulla Counties. There is a danger of catastrophic and unsurvivable storm surge for Apalachee Bay. Inundation near the coast of 15 to 20 feet is possible. Flooding Rain Threat: Widespread heavy rainfall is expected, with additional rainfall of 5 to 10 inches and local amounts to 15 inches in the forecast. Flash flooding is expected, and considerable, to potentially catastrophic, flash flooding is likely. Minor to moderate riverine flooding is likely, although major flooding is possible. Areas that experienced heavy rainfall on Wednesday and Thursday will only make the region more vulnerable to heavy rainfall today and tonight. Even though the hurricane is forecast to be moving quickly, very high rainfall rates and already saturated soils will combine for a serious flood risk across the region. Be prepared for widespread flash flooding and quickly rising rivers and streams. A Flood Watch remains in effect for the entire area. Tornadoes: A few tornadoes will be possible ahead of and along and east of the track of Helene. Conditions will improve on Friday. POTENTIAL IMPACTS ----------------- * WIND: Potential impacts from the main wind event are now unfolding across the Big Bend region of Florida, and along the I-75 corridor of south Georgia. Remain well sheltered from life- threatening wind having significant damaging or devastating impacts. If realized, these impacts include: - Structural damage to sturdy buildings, some with complete roof and wall failures. Complete destruction of mobile homes. Damage greatly accentuated by large airborne projectiles. Locations may be uninhabitable for weeks or months. - Numerous large trees snapped or uprooted along with fences and roadway signs blown over. - Many roads impassable from large debris, and more within urban or heavily wooded places. Many bridges, causeways, and access routes impassable. - Widespread power and communications outages. Remain well sheltered. * SURGE: Potential impacts from the main surge event are now unfolding along the coast of Apalachee Bay. Remain well away from life-threatening surge having catastrophic impacts. If realized, these impacts include: - Widespread deep inundation, with storm surge flooding greatly accentuated by powerful battering waves. Structural damage to buildings, with many washing away. Damage greatly compounded from considerable floating debris. Locations may be uninhabitable for an extended period. - Near-shore escape routes and secondary roads washed out or severely flooded. Flood control systems and barriers may become stressed. - Extreme beach erosion. New shoreline cuts possible. - Massive damage to marinas, docks, boardwalks, and piers. Numerous small craft broken away from moorings with many lifted onshore and stranded. Elsewhere across eastern Florida panhandle, Florida Big Bend, southeastern Alabama and southwestern Georgia, little to no impact is anticipated. * FLOODING RAIN: Potential impacts from the flooding rain are still unfolding across the Florida Big Bend region, Southwest Georgia, Southeast Alabama, and the eastern Florida Panhandle. Remain well guarded against life- threatening flood waters additional devastating impacts. If realized, these impacts include: - Extreme rainfall flooding may prompt numerous evacuations and rescues. - Rivers and tributaries may overwhelmingly overflow their banks in many places with deep moving water. Small streams, creeks, and ditches may become raging rivers. Flood control systems and barriers may become stressed. - Flood waters can enter numerous structures within multiple communities, some structures becoming uninhabitable or washed away. Numerous places where flood waters may cover escape routes. Streets and parking lots become rivers of raging water with underpasses submerged. Driving conditions become very dangerous. Numerous road and bridge closures with some weakened or washed out. * TORNADOES: Potential impacts from tornadoes are still unfolding across the eastern Florida Big Bend region and south Georgia. Remain well braced against a dangerous tornado event having additional significant impacts. If realized, these impacts include: - The occurrence of scattered tornadoes can hinder the execution of emergency plans during tropical events. - Several places may experience tornado damage with a few spots of considerable damage, power loss, and communications failures. - Locations could realize roofs torn off frame houses, mobile homes demolished, boxcars overturned, large trees snapped or uprooted, vehicles tumbled, and small boats tossed about. Dangerous projectiles can add to the toll. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Follow the advice of local officials. * OTHER PREPAREDNESS INFORMATION: Now is the time to stay inside and away from windows. Listen for updates and be ready in case you lose electrical power. Keep a battery- powered radio, charged cell phone and flashlight handy. During the peak of the storm be ready to move quickly. Keep your shoes on and rain gear handy. Boots and athletic shoes offer the best foot protection if you become unexpectedly exposed to the weather. Keep your cell phone charged and in power-saving mode. If you lose power, use it sparingly and mainly for personal emergencies and check-ins. Do not venture outside while in the eye of a hurricane as any improvement in weather will only be temporary. Once the eye passes, conditions will become life threatening as winds immediately return to dangerous speeds, so remain safely sheltered from the storm. Do not be a thrill seeker or risk your life for senseless photos or videos. Quickly move to the safest place within your shelter if it begins to fail, preferably an interior room on the lowest floor as long as flooding is not a concern. If you are prone to flooding or in an area under a storm surge watch or warning, be prepared for the possibility of a quick and dramatic rise in water levels. If a tornado warning is issued for your area, quickly move to the safest place within your shelter. Protect your head and body. If an Extreme Wind Warning is issued for your area, move to the safest place within your shelter. Take the same life-saving actions as if it were a violent tornado. * ADDITIONAL SOURCES OF INFORMATION: - For information on appropriate preparations see ready.gov - For additional disaster preparedness information see redcross.org NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in Tallahassee FL around 6 AM EDT, or sooner if conditions warrant.
