Hurricane and Tropical Storm Warnings remain active across Southeast Louisiana and Southern Mississippi. In addition to the potential for damaging winds, Francine will also bring the threat of life-threatening storm surge along the coastline and lakeshores of Southeast Louisiana and Southern Mississippi where Storm Surge Warnings are currently in place. Heavy rainfall along and to the east of the track will have the potential to cause flooding and flash flooding even in areas that don't normally flood. Rainfall flooding could be worsened due to the heavy rainfall that saturated grounds just last week. POTENTIAL IMPACTS ----------------- * WIND: Potential impacts from the main wind event are now unfolding across southeast Louisiana and south Mississippi. Remain well sheltered from life- threatening wind having possible extensive impacts. If realized, these impacts include: - 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. Potential impacts from the main wind event are also now unfolding across southeast Louisiana and south Mississippi. Remain well sheltered from dangerous wind having possible limited to significant impacts. * SURGE: Potential impacts from the main surge event are now unfolding across Coastal southeast Louisiana and south Mississippi. Remain well away from life-threatening surge having potential devastating impacts. If realized, these impacts include: - Widespread deep inundation, with storm surge flooding greatly accentuated by powerful battering waves. Structural damage to buildings, with many washing away. Damage greatly compounded from considerable floating debris. Locations may be uninhabitable for an extended period. - Near-shore escape routes and secondary roads washed out or severely flooded. Flood control systems and barriers may become stressed. - Extreme beach erosion. New shoreline cuts possible. - Massive damage to marinas, docks, boardwalks, and piers. Numerous small craft broken away from moorings with many lifted onshore and stranded. Elsewhere across Southeast Louisiana and South Mississippi, little to no impact is anticipated. * FLOODING RAIN: Potential impacts from the flooding rain are still unfolding across Southeast Louisiana and South Mississippi. Remain well guarded against life-threatening flood waters having potential 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. * TORNADOES: Potential impacts from tornadoes are still unfolding across southeast Louisiana and south Mississippi. Remain well braced against a dangerous tornado event having possible significant impacts. If realized, these impacts include: - The occurrence of scattered tornadoes can hinder the execution of emergency plans during tropical events. - Several places may experience tornado damage with a few spots of considerable damage, power loss, and communications failures. - Locations could realize roofs torn off frame houses, mobile homes demolished, boxcars overturned, large trees snapped or uprooted, vehicles tumbled, and small boats tossed about. Dangerous projectiles can add to the toll. Potential impacts from tornadoes are still unfolding across the region. Remain well braced against a tornado event having at least limited impacts. 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. 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 New Orleans LA as conditions warrant.
