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 expected to extend well east of the center of the storm. There is an elevated risk for tornadoes associated with Helene. The risk for tornadoes will increase during the day Thursday and peaking Thursday night into early Friday morning. Tropical storm force winds are forecast to increase across Southeast Georgia and the adjacent Atlantic Georgia waters Thursday evening, then spreading into Southeast South Carolina and the adjacent coastal waters Thursday night. Winds speeds are expected to peak late Thursday night as the center of Helene moves across central Georgia. In addition, rain bands are expected to rapidly lift north across Southeast Georgia and the South Carolina Lowcountry Thursday night. These rain bands should produce periods of gusty winds and possibly spawning some tornadoes. Rainfall amounts across Southeast Georgia are forecast to range between 3 to 5 inches and 1.5 to 4 inches across Southeast South Carolina. Isolated higher amounts are possible, especially west of the Interstate 95 corridor. Rainfall rates will increase through Thursday, with the heaviest rain band sweeping across the region Thursday night into early Friday morning. In addition to high surf, strong and dangerous rip currents and beach erosion, storm surge inundation of 1 to 3 ft is possible along the coast of Southeast Georgia and the South Carolina Lowcountry. 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. * FLOODING RAIN: Protect against dangerous rainfall flooding having possible significant impacts across southeast South Carolina and southeast Georgia. Potential impacts include: - Moderate rainfall flooding could prompt some rescues. - Rivers and tributaries could quickly become swollen with swifter currents and overspill their banks in a few places, especially in normally vulnerable spots. Small streams, creeks, canals, and ditches overflow. - Flood waters can enter some structures or weaken foundations. Several places could experience expanded areas of rapid inundation at underpasses, low-lying spots, and poor drainage areas. Some streets and parking lots take on moving water as storm drains and retention ponds overflow. Driving conditions become hazardous. Some road and bridge closures. * SURGE: Protect against locally hazardous surge having possible limited impacts across south 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. * OTHER COASTAL HAZARDS: In addition to coastal inundation, high surf, strong and dangerous rip currents and beach erosion can be expected. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * 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. If you are a visitor, be sure to know the name of the city or town in which you are staying and the name of the county or parish in which it resides. Listen for these locations in local news updates. Pay attention for instructions from local authorities. If a Tornado Warning is issued for your area, be ready to shelter quickly, preferably away from windows and in an interior room not prone to flooding. If driving, scan the roadside for quick shelter options. 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 6 PM EDT, or sooner if conditions warrant. |
