Detailed Description |
HLSTAE This product covers eastern Florida panhandle, Florida Big Bend, southeastern Alabama and southwestern Georgia **HELENE FORECAST TO MAKE LANDFALL AS A MAJOR HURRICANE ALONG THE FLORIDA BIG BEND ON THURSDAY.** NEW INFORMATION --------------- * CHANGES TO WATCHES AND WARNINGS: - None * CURRENT WATCHES AND WARNINGS: - A Storm Surge Watch and Hurricane Watch are in effect for Coastal Dixie, Coastal Franklin, Coastal Jefferson, Coastal Taylor, Coastal Wakulla, and Inland Dixie - A Hurricane Watch is in effect for Gadsden, Inland Franklin, Inland Jefferson, Inland Taylor, Inland Wakulla, Lafayette, Leon, Liberty, and Madison - A Tropical Storm Watch is in effect for Calhoun, Coastal Bay, Coastal Gulf, Inland Bay, and Inland Gulf * STORM INFORMATION: - About 740 miles south of Panama City or about 710 miles south of Apalachicola - 19.5N 84.3W - Storm Intensity 45 mph - Movement Northwest or 310 degrees at 12 mph SITUATION OVERVIEW ------------------ . INCREASING CONFIDENCE FOR SIGNIFICANT IMPACTS ACROSS THE REGION. At 11 AM EDT, Tropical Storm Helene has formed in the northwestern Caribbean Sea. It is forecast to gradually strengthen throughout the day as it heads for the Yucatan Channel. From there, it heads northeast through the eastern Gulf of Mexico while rapidly strengthening into a Major Hurricane ahead of landfall as a Major Hurricane along the northeast Gulf Coast late Thursday into early Friday. Confidence is increasing for potentially significant impacts across our region including high winds, significant and life-threatening storm surge in Apalachee Bay, flash flooding from heavy rainfall, and a few tornadoes. Conditions could begin to deteriorate as early as Wednesday night, so preparations should be completed by sunset Wednesday evening. Wind Threat: It is increasingly likely that a major hurricane will make landfall somewhere along the FL Big Bend coast on Thursday. While exact impacts will be heavily dependent on the eventual track, expect catastrophic wind damage near the eventual landfall point and inland along the track. Widespread power outages, damage to critical infrastructure, widespread inaccessibility due to road blockages, and damage to structures will all be possible. Some areas may experience power outages for a week or more. Further away from the center, significant wind damage and power outages will also be possible. Surge Threat: Significant and life-threatening storm surge is forecast for Apalachee Bay. Not only is this forecast to be a major hurricane at landfall, but it is forecast to be a large hurricane as well. Storm surge may begin to arrive as early as late Wednesday night ahead of the winds. This forecast, if realized, is a nightmare surge scenario for Apalachee Bay. Please please please take any evacuation orders seriously. Flooding Rain Threat: Widespread heavy rainfall is forecast with this system and may lead to both flash flooding and riverine flooding. Even though the hurricane is forecast to be moving quickly, very high rainfall rates and already saturated soils in some places will still combine for a serious flood risk across the region. Be prepared for flash flooding and quickly rising rivers and streams. A Flood Watch is in effect for the entire area. Tornadoes: While not the highest threat with this system, a few tornadoes will be possible along and east of the eventual track. POTENTIAL IMPACTS ----------------- * WIND: Prepare for life-threatening wind having possible devastating impacts across The Florida Big Bend. Potential impacts in this area 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. Also, prepare for life-threatening wind having possible limited to extensive impacts across the Florida Panhandle, Southeast Alabama, and Southwest Georgia. * SURGE: Prepare for life-threatening surge having possible catastrophic impacts across the coastal Florida Big Bend. Potential impacts in this area 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: Prepare for life-threatening rainfall flooding having possible extensive impacts across the Florida Big Bend and Southwest Georgia. Potential impacts include: - Major rainfall flooding may prompt many evacuations and rescues. - Rivers and tributaries may rapidly overflow their banks in multiple places. Small streams, creeks, and ditches may become dangerous rivers. Flood control systems and barriers may become stressed. - Flood waters can enter many structures within multiple communities, some structures becoming uninhabitable or washed away. Many places where flood waters may cover escape routes. Streets and parking lots become rivers of moving water with underpasses submerged. Driving conditions become dangerous. Many road and bridge closures with some weakened or washed out. Prepare for dangerous rainfall flooding having possible significant impacts elsewhere across the region. * TORNADOES: Prepare for a tornado event having possible limited impacts across the eastern Florida Big Bend and south central Georgia. Potential impacts include: - The occurrence of isolated tornadoes can hinder the execution of emergency plans during tropical events. - A few places may experience tornado damage, along with power and communications disruptions. - Locations could realize roofs peeled off buildings, chimneys toppled, mobile homes pushed off foundations or overturned, large tree tops and branches snapped off, shallow-rooted trees knocked over, moving vehicles blown off roads, and small boats pulled from moorings. Elsewhere across eastern Florida panhandle, Florida Big Bend, southeastern Alabama and southwestern Georgia, little to no impact is anticipated. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Follow the advice of local officials * OTHER PREPAREDNESS INFORMATION: Now is the time to check your emergency plan and emergency supplies kit and take necessary actions to protect your family and secure your home or business. When making safety and preparedness decisions, do not focus on the exact forecast track since hazards such as flooding rain, damaging wind gusts, storm surge, and tornadoes extend well away from the center of the storm. If in a place that is vulnerable to high wind, such as near large trees, a manufactured home, upper floors of a high-rise building, or on a boat, plan to move to safe shelter. If you live in a place particularly vulnerable to flooding, such as near the Gulf of Mexico or a large inland lake, in a low-lying or poor drainage area, or near an already swollen river, plan to move to safe shelter on higher ground. Always heed the advice of local officials and comply with orders that are issued. Do not needlessly jeopardize your life or the lives of others. When securing your property, outside preparations should be concluded as soon as possible before conditions deteriorate. The onset of strong gusty winds or flooding can cause certain preparedness activities to become unsafe. Be sure to let friends and family members know of your intentions for weathering the storm and your whereabouts. Have someone located away from the threatened area serve as your point of contact. Share vital contact information with others. Keep cell phones handy and charged. Check on those who may not be fully aware of the situation or who are unable to make personal preparations. If you are a visitor, know the name of the county in which you are located and where it is relative to current watches and warnings. If staying at a hotel, ask the management staff about their onsite disaster plan. Listen for evacuation orders, especially pertaining to area visitors. Closely monitor weather.gov, NOAA Weather Radio and local news outlets for official storm information. Listen for possible changes to the forecast. * 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 5 PM EDT, or sooner if conditions warrant. |
