Tropical Cyclone Statement issued September 25 at 11:12PM EDT by NWS Charleston SC HLSCHS This product covers southeast South Carolina and southeast Georgia **INCREASING RISK FOR TROPICAL TORNADOES AND OTHER HAZARDS FROM HURRICANE HELENE** NEW INFORMATION --------------- * CHANGES TO WATCHES AND WARNINGS: - None * CURRENT WATCHES AND WARNINGS: - A Tropical Storm Warning is in effect for Allendale, Beaufort, Bulloch, Candler, Charleston, Coastal Bryan, Coastal Chatham, Coastal Colleton, Coastal Jasper, Coastal Liberty, Coastal McIntosh, Dorchester, Effingham, Evans, Hampton, Inland Berkeley, Inland Bryan, Inland Chatham, Inland Colleton, Inland Jasper, Inland Liberty, Inland McIntosh, Jenkins, Long, Screven, Tattnall, and Tidal Berkeley * STORM INFORMATION: - About 700 miles south-southwest of Savannah GA - 23.1N 86.6W - Storm Intensity 85 mph - Movement North or 360 degrees at 9 mph SITUATION OVERVIEW ------------------ Hurricane Helene is expected to strengthen into a major hurricane as it moves northward across the eastern Gulf of Mexico by Thursday. The storm is forecast to make landfall around the Big Bend area of Florida Thursday evening, tracking northward across Georgia Thursday night into early Friday. Helene is forecast to become a very large storm, with impacts extending well to the east of where the storm tracks. There is an elevated risk for tornadoes associated with Helene. The risk for tornadoes will increase during the day Thursday and peak Thursday night into early Friday morning. Tropical storm force winds, mainly in frequent gusts of 40 to 60 mph, are forecast to increase across Southeast Georgia and the adjacent Atlantic Georgia waters Thursday evening, then expand into Southeast South Carolina and the adjacent coastal waters Thursday night. Wind speeds should peak late Thursday night as the center of Helene moves across central Georgia. Rain bands with Helene will begin to impact Southeast Georgia before daybreak Thursday, then increase in both coverage and intensity across the remainder of Southeast South Carolina and Southeast Georgia Thursday into Thursday night. The rain should quickly end Friday morning as Helene moves into the southern Appalachians. Rainfall amounts will average 1.5 to 3 inches with isolated higher amounts possible, especially west of the Interstate 95 corridor. Minor flooding of low-lying and poor drainage areas is likely in some areas with isolated flash flooding possible. Storm surge inundation of 1 to 3 ft is possible along the coast of Southeast Georgia and the South Carolina Lowcountry. In addition, high surf, strong and dangerous rip currents, and beach erosion are likely at the beaches. POTENTIAL IMPACTS ----------------- * TORNADOES: Protect against a particularly dangerous tornado event having possible extensive impacts across Southeast South Carolina and Southeast Georgia. Potential impacts include: - Numerous tornadoes can greatly hinder the execution of emergency plans. - Tornadoes could produce pockets of extensive destruction, power loss, and communications failures. In some locations, tornado winds and deadly projectiles demolish sturdy buildings, sweep away structures upon weak foundations, obliterate mobile homes, snap off and uproot large trees, lift vehicles off the ground and throw with distance, and destroy small boats destroyed. * WIND: Protect against hazardous wind having possible limited impacts across southeast South Carolina and southeast Georgia. Potential impacts include: - Damage to porches, awnings, carports, sheds, and unanchored mobile homes. Unsecured lightweight objects blown about. - Large tree limbs broken off. A few trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. - Some roads impassable due to debris, particularly within urban or heavily wooded locations. Hazardous driving conditions on bridges and other elevated roadways, especially for high profile vehicles. - Isolated to scattered power and communications outages. * SURGE: Protect against locally hazardous surge having possible limited impacts across coastal South Carolina and coastal Georgia. Potential impacts in this area include: - Localized inundation of saltwater mainly along immediate shorelines and in low-lying spots farther inland near rivers and creeks. - Sections of near-shore roads and parking lots become overspread with surge water. Driving conditions hazardous in places where surge water covers the road. - Minor to moderate beach erosion. Heavy surf possibly breaching dunes, mainly in normally vulnerable locations. Strong rip currents. - Minor to locally moderate damage to marinas, docks, boardwalks, and piers. A few small craft broken away from moorings. Elsewhere across southeast South Carolina and southeast Georgia, little to no impact is anticipated. * FLOODING RAIN: Protect against life-threatening rainfall flooding having possible extensive impacts across far interior Southeast Georgia. Potential impacts include: - Major rainfall flooding could prompt many rescues. - Rivers and tributaries could rapidly overflow their banks in multiple locations. Small streams, creeks, canals, ditches may become dangerous rivers. Flood control systems and barriers could become stressed. - Flood waters could enter many structures within multiple communities; some structures become uninhabitable or are washed away. Flood waters could cover multiple 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. - Drinking water and sewer services could be negatively impacted. - Hazardous containers and materials could possibly be present in flood waters. Protect against dangerous rainfall flooding having possible significant impacts across the remainder of Southeast South Carolina and Southeast Georgia. * OTHER COASTAL HAZARDS: In addition to coastal inundation, high surf, strong and dangerous rip currents and beach erosion can be expected. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Follow the advice of local officials. * OTHER PREPAREDNESS INFORMATION: Now is the time to complete all preparations to protect life and property in accordance with your emergency plan. Ensure you are in a safe location before the onset of strong winds or possible flooding. Keep cell phones well charged. Cell phone chargers for automobiles can be helpful, but be aware of your risk for deadly carbon monoxide poisoning if your car is left idling in a garage or other poorly ventilated area. Closely monitor weather.gov, NOAA Weather radio or local news outlets for official storm information. Be ready to adapt to possible changes to the forecast. Ensure you have multiple ways to receive weather warnings. * ADDITIONAL SOURCES OF INFORMATION: - For information on appropriate preparations see ready.gov - For information on creating an emergency plan see getagameplan.org - For additional disaster preparedness information see redcross.org NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in Charleston SC around 5 AM EDT, or sooner if conditions warrant.
