Helene will continue to rapidly strengthen as it moves northward and is predicted to make landfall in the Florida Big Bend around sunset. Given the size of Helene, impacts will be experienced far from the center. After landfall, Helene will rapidly move north into southern Georgia tonight. Hurricane force wind gusts are expected this evening for the Suwannee Valley and far inland areas of southeast Georgia. Sustained major hurricane strength winds will be possible for Suwannee Valley tonight if Helene tracks more eastward. Elsewhere, tropical storm force winds will become widespread this afternoon and early evening. Storm surge inundation of 1 to 3 feet with isolated locations up to 4 feet is expected along the northeast Florida and southeast Georgia Atlantic coasts and in the St Johns River basin. Scattered tornadoes are possible within the outer rainbands through tonight across northeast Florida and southeast Georgia. Rainfall amounts of 3 to 6 inches, with locally higher amounts possible, are expected across the I-75 corridor into inland southeast Georgia, with 1 to 3 inches with locally higher amounts further east. Flash flooding will be possible especially for Suwannee Valley and far inland southeast Georgia. POTENTIAL IMPACTS ----------------- * WIND: Potential impacts from the main wind event are now unfolding across Suwannee Valley and far inland southeast Georgia. Remain well sheltered from life- threatening wind having devastating impacts. If realized, these impacts 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. Potential impacts from the main wind event are also now unfolding across the remainder of northeast Florida and southeast Georgia. Remain well sheltered from dangerous wind having limited to extensive impacts. * TORNADOES: Potential impacts from tornadoes are still unfolding across northeast Florida and southeast Georgia. Remain well braced against a particularly dangerous tornado event having possible extensive impacts. If realized, these 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. * SURGE: Potential impacts from the main surge event are now unfolding across coastal northeast Florida and southeast Georgia and within the St. Johns River Basin. Remain well away from locally hazardous surge having additional limited impacts. If realized, these impacts include: - Localized inundation with storm surge flooding mainly along immediate shorelines and in low-lying spots, or in areas farther inland near where higher surge waters move ashore. - Sections of near-shore roads and parking lots become overspread with surge water. Driving conditions dangerous in places where surge water covers the road. - Moderate beach erosion. Heavy surf also breaching dunes, mainly in usually vulnerable locations. Strong rip currents. - Minor to locally moderate damage to marinas, docks, boardwalks, and piers. A few small craft broken away from moorings. * FLOODING RAIN: Potential impacts from the flooding rain are still unfolding across Suwanee Valley and far inland southeast Georgia. Remain well guarded against life- threatening flood waters having possible extensive impacts. If realized, these 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, canals, 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. Potential impacts from the flooding rain are still unfolding across the remainder of northeast florida and southeast Georgia. 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. During the peak of the storm be ready to move quickly. Keep your shoes on and rain gear handy. Boots and athletic shoes offer the best foot protection if you become unexpectedly exposed to the weather. 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 an Extreme Wind Warning is issued for your area, move to the safest place within your shelter. Take the same life-saving actions as if it were a violent tornado. Do not be a thrill seeker or risk your life for senseless photos or videos. Quickly move to the safest place within your shelter if it begins to fail, preferably an interior room on the lowest floor as long as flooding is not a concern. If you are prone to flooding or in an area under a storm surge watch or warning, be prepared for the possibility of a quick and dramatic rise in water levels. 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 Jacksonville FL around 11 PM EDT, or sooner if conditions warrant.
