* LOCATIONS AFFECTED - Port Sulphur - Empire - Venice * WIND - LATEST LOCAL FORECAST: Below tropical storm force wind - Peak Wind Forecast: 25-35 mph with gusts to 55 mph - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: 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. - PREPARE: Efforts to protect life and property should now be rigorously underway. Prepare for considerable wind damage. - ACT: Act now to complete preparations before the wind becomes hazardous. - POTENTIAL IMPACTS: Extensive - Considerable roof damage to sturdy buildings, with some having window, door, and garage door failures leading to structural damage. Mobile homes severely damaged, with some destroyed. Damage accentuated by airborne projectiles. Locations may be uninhabitable for weeks. - Many large trees snapped or uprooted along with fences and roadway signs blown over. - Some roads impassable from large debris, and more within urban or heavily wooded places. Several bridges, causeways, and access routes impassable. - Large areas with power and communications outages. * STORM SURGE - LATEST LOCAL FORECAST: Life-threatening storm surge possible - Peak Storm Surge Inundation: The potential for 3-5 feet above ground somewhere within surge prone areas - Window of concern: Friday morning until Saturday morning - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for storm surge flooding greater than 3 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 3 feet above ground. - PREPARE: Storm surge flooding preparations should be underway. Assemble disaster supplies and know your evacuation route. - ACT: Leave if evacuation orders are given for your area. Failure to heed evacuation orders may result in the loss of your life. - POTENTIAL IMPACTS: Significant - Areas of inundation with storm surge flooding accentuated by waves, mainly outside the levees. Damage to several buildings, mainly near the coast. - Sections of escape routes and secondary roads become weakened or washed out, especially in usually vulnerable low spots. - Major shoreline and marsh erosion. - Moderate damage to marinas, docks, boardwalks, and piers. Several small craft broken away from moorings, especially in unprotected anchorages. * FLOODING RAIN - LATEST LOCAL FORECAST: - Peak Rainfall Amounts: Additional 1-3 inches, with locally higher amounts - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Little or no potential for flooding rain - The flooding rain threat has decreased from the previous assessment. - PLAN: There is little or no potential for flooding rain. - PREPARE: Little to no preparations are needed to protect against flooding rain at this time. - ACT: Monitor for changes to the forecast. - POTENTIAL IMPACTS: Little to None - Little to no potential impacts from flooding rain. * TORNADO - LATEST LOCAL FORECAST: - Situation is unfavorable for tornadoes - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Tornadoes not expected - The tornado threat has decreased from the previous assessment. - PLAN: Tornadoes are not expected. Showers and thunderstorms with gusty winds may still occur. - PREPARE: Little to no preparations needed to protect against tornadoes at this time. Keep informed of the latest tornado situation. - ACT: Listen for changes in the forecast. - POTENTIAL IMPACTS: Little to None - Little to no potential impacts from tornadoes. * FOR MORE INFORMATION: - https://gohsep.la.gov/emergency
