A Hurricane Warning means hurricane-force winds are expected somewhere within this area within the next 36 hours
* LOCATIONS AFFECTED - Hilton Head Island - Beaufort - Bluffton
* WIND - LATEST LOCAL FORECAST: Equivalent Tropical Storm force wind - Peak Wind Forecast: 45-55 mph with gusts to 70 mph - Window for Tropical Storm force winds: Wednesday afternoon until Thursday evening - POTENTIAL THREAT TO LIFE AND PROPERTY: Potential for wind 74 to 110 mph - The wind threat has remained nearly steady from the previous assessment. - PLAN: Plan for life-threatening wind of equivalent CAT 1 or 2 hurricane force due to possible forecast changes in track, size, or intensity. - PREPARE: Remaining efforts to protect life and property should be urgently completed. Prepare for considerable wind damage. - ACT: Move to safe shelter before the wind becomes hazardous. - POTENTIAL IMPACTS: Extensive - Considerable roof damage to sturdy buildings, with some window, door, and garage door failures leading to structural damage. Mobile homes severely damaged, with some destroyed. Damage accentuated by airborne projectiles. Some locations may be uninhabitable for weeks. - Danger of death or injury from falling objects and airborne projectiles outside. - Large trees snapped or uprooted. - Some roads impassable from large debris, and more within urban or heavily wooded locations. Several bridges and access routes impassable. - Large areas with power and communications outages, which could persist for days. - Several secured small craft could break free from moorings.
* STORM SURGE - LATEST LOCAL FORECAST: Life-threatening storm surge possible - Peak Storm Surge Inundation: The potential for 4-7 feet above ground somewhere within surge prone areas - Window of concern: Begins Wednesday morning - POTENTIAL THREAT TO LIFE AND PROPERTY: Potential for storm surge flooding greater than 6 feet above ground - The storm surge threat has remained nearly steady from the previous assessment. - PLAN: Plan for life-threatening storm surge flooding of greater than 6 feet above ground. - PREPARE: Evacuation efforts should soon be brought to completion before driving conditions become unsafe. - ACT: Leave immediately if evacuation orders are given for your area to avoid being cut off from emergency services or needlessly risk lives. - POTENTIAL IMPACTS: Extensive - Large areas of deep inundation of saltwater along immediate shorelines and in low-lying spots farther inland near rivers and creeks, with storm surge flooding accentuated by battering waves. Structural damage to buildings, with several washing away. Damage compounded by floating debris. Locations may be uninhabitable for an extended period. - Large sections of near-shore escape routes and secondary roads washed out or flooded and impassable. Flood control systems and barriers could become stressed. - Severe beach erosion with significant dune loss. - Major damage to marinas, docks, boardwalks, and piers. Many small craft broken away from moorings, especially in unprotected anchorages, with some lifted onshore and stranded. - Drinking water and sewer services negatively impacted. - Hazardous containers and materials possibly present in surge waters.
* FLOODING RAIN - LATEST LOCAL FORECAST: Flash Flood Watch is in effect - Peak Rainfall Amounts: Additional 4-8 inches, with locally higher amounts - POTENTIAL THREAT TO LIFE AND PROPERTY: Potential for moderate flooding rain - The flooding rain threat has remained nearly steady from the previous assessment. - PLAN: Emergency plans should include the potential for moderate flooding from heavy rain. Evacuations and rescues are possible. - PREPARE: Consider protective actions if you are in an area vulnerable to flooding. - ACT: Heed any flood watches and warnings. Failure to take action may result in serious injury or loss of life. - POTENTIAL IMPACTS: Significant - 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.
* TORNADO - LATEST LOCAL FORECAST: - Situation is somewhat favorable for tornadoes - POTENTIAL THREAT TO LIFE AND PROPERTY: Potential for a few tornadoes - The tornado threat has remained nearly steady from the previous assessment. - PLAN: Emergency plans should include the potential for a few tornadoes. - PREPARE: If your shelter is particularly vulnerable to tornadoes, prepare to relocate to safe shelter before hazardous weather arrives. - ACT: If a tornado warning is issued, be ready to shelter quickly. - POTENTIAL IMPACTS: Limited - Isolated tornadoes can hinder the execution of emergency plans. - Isolated locations could experience tornado damage, along with power and communications disruptions. - In isolated locations, tornadoes could damage trees, vehicles, boats and buildings, especially mobile homes and other poorly constructed structures.
