| Detailed Description |
HLSCHS This product covers southeast South Carolina and southeast Georgia **HURRICANE HELENE MAKES LANDFALL IN THE FLORIDA BIG BEND. TROPICAL TORNADOES AND DAMAGING WIND GUSTS POSSIBLE THROUGH TONIGHT** 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 220 miles southwest of Savannah GA - 29.9N 83.9W - Storm Intensity 140 mph - Movement North-northeast or 15 degrees at 24 mph SITUATION OVERVIEW ------------------ Major Hurricane Helene has just made landfall along the Big Bend area of Florida. Helene will slowly weaken as it moves over land, but will remain quite strong as it tracks northward across Georgia overnight into early Friday. Helene is a very large storm, with significant impacts extending well to the east of where the storm tracks. There is a high risk for tornadoes associated with Helene and several tornadoes have already been observed. The tornado risk will continue into early Friday morning before quickly ending. Tornadoes from tropical storms or hurricanes can form and move very quickly, so be prepared to take quick action if a Tornado Warning is issued for your location. Tropical storm force winds have begun to spread into portions of Southeast Georgia and the coastal waters. Frequent gusts of 45 to 65 mph are forecast to increase across Southeast Georgia and the adjacent Atlantic waters over the next couple of hours, then expand into Southeast South Carolina and the adjacent coastal waters later tonight. Wind speeds should peak between 3 AM and 6 AM as the center of Helene moves across central Georgia. Rainbands associated with Helene impacting Southeast South Carolina and Southeast Georgia will increase in both coverage and intensity through the night. The rain will quickly end Friday morning as Helene moves into the southern Appalachians. Additional rainfall amounts around 1 to 2 inches are expected with isolated higher amounts possible, especially for areas across the far interior South Carolina and Georgia counties. Minor flooding of low-lying and poor drainage areas is likely in some locations with isolated flash flooding possible. The risk for flooding may become locally enhanced at the coast during high tide later tonight. Storm surge inundation of 1 to 3 ft is possible along the coast of Southeast Georgia and the South Carolina Lowcountry tonight. In addition, high surf, strong and dangerous rip currents, and beach erosion are likely at all area beaches into Friday. POTENTIAL IMPACTS ----------------- * TORNADOES: Potential impacts from tornadoes are still unfolding across Southeast South Carolina and Southeast Georgia. Remain well braced against a particularly dangerous tornado event having additional extensive impacts. If realized, these 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: Potential impacts from the main wind event are now unfolding across southeast South Carolina and southeast Georgia. Remain well sheltered from dangerous wind having possible significant impacts. If realized, these impacts include: - Some damage to roofing and siding materials, along with damage to porches, awnings, carports, and sheds. A few buildings experiencing window, door, and garage door failures. Mobile homes damaged, especially if unanchored. Unsecured lightweight objects become dangerous projectiles. - Several large trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. - Some roads impassable from large debris, and more within urban or heavily wooded places. A few bridges and access routes impassable. - Travel by vehicle or on foot increasingly difficult. Danger of death or injury from falling objects such as trees or electric wires outside. - Scattered power and communications outages, but more prevalent in areas with above ground lines, which could persist for hours or days. - Some poorly secured small craft could break loose from their moorings. * SURGE: Potential impacts from the main surge event are soon to be unfolding across coastal South Carolina and coastal Georgia. Remain well away from locally hazardous surge having possible limited impacts. If realized, these impacts 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: Potential impacts from the flooding rain are still unfolding across Southeast South Carolina and Southeast Georgia. Remain well guarded against flood waters having possible extensive impacts. If realized, these impacts include: - Rivers and tributaries could rapidly overflow their banks in multiple locations. Small streams, creeks, canals, ditches may become dangerous rivers. - Streets, parking lots, and low-lying areas may become flooded. Driving conditions become dangerous. - Be especially cautious at night when it is harder to recognize the dangers of flooding. - Hazardous containers and materials could possibly be present in flood waters. * 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 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. 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. If a tornado warning is issued for your area, quickly move to the safest place within your shelter. Protect your head and body. * 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 6 AM EDT, or sooner if conditions warrant. |
