Helene's fast forward speed will allow strong, damaging winds, especially in gusts, to penetrate well inland across the southeastern United States. Tropical storm wind gusts around 60 mph will be possible through mid morning as Helene moves west of the area. Tornadoes will also be possible with highest confidence along and south of I-20 through Friday morning. POTENTIAL IMPACTS ----------------- * WIND: Protect against dangerous wind having possible significant impacts across the Augusta Metro Area and the CSRA. Potential impacts in this area 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. Several fences and roadway signs blown over. - Some roads impassable from large debris, and more within urban or heavily wooded places. A few bridges, causeways, and access routes impassable. - Scattered power and communications outages, but more prevalent in areas with above ground lines. * TORNADOES: Protect against a particularly dangerous tornado event having possible extensive impacts across the region, especially south and east of I-20. Potential impacts include: - The occurrence of numerous tornadoes can greatly hinder the execution of emergency plans during tropical events. - Many places may experience tornado damage with a few spots of immense destruction, power loss, and communications failures. - Locations could realize roof and wall failures of sturdy buildings with some being leveled, structures upon weak foundations blown away, mobile homes obliterated, large trees twisted and snapped with forested trees uprooted, vehicles lifted off the ground and thrown, and small boats destroyed. Large and deadly projectiles can add to the toll. * FLOODING RAIN: Protect against life-threatening rainfall flooding having possible devastating impacts across the CSRA and south/central Midlands. Potential 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, canals, arroyos, and ditches may become raging rivers. In mountain areas, deadly runoff may rage down valleys while increasing susceptibility to rockslides and mudslides. 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. Prepare for rainfall flooding having high to moderate impacts across the Midlands and Pee Dee. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * OTHER PREPAREDNESS INFORMATION: 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. 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. Rapidly rising flood waters are deadly. If you are in a flood-prone area, consider moving to higher ground. Never drive through a flooded roadway. Remember, turn around don't drown! 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, consider moving to a safer shelter before the onset of strong winds or flooding. 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 from the state of South Carolina see scemd.org - For information from the state of Georgia see gema.ga.gov NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in Columbia SC around 1130 AM, or sooner if conditions warrant.
