If it becomes a tropical storm it will be named Claudette. Rainbands are already moving on shore and winds are increasing over the coastal waters with numerous oil platforms seeing winds gusting to 40 mph already. POTENTIAL IMPACTS ----------------- * FLOODING RAIN: Protect against dangerous rainfall flooding having possible significant impacts mainly along and east of I-55. Potential impacts include: - Moderate rainfall flooding may prompt several evacuations and rescues. - Rivers and tributaries may quickly become swollen with swifter currents and overspill their banks in a few places, especially in usually vulnerable spots. Small streams, creeks, canals, and ditches overflow. - Flood waters can enter some structures or weaken foundations. Several places may 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. Protect against locally hazardous rainfall flooding having possible limited impacts mainly west of I-55. * TORNADOES: Protect against a tornado event having possible limited impacts across Southeast Louisiana and South Mississippi. Potential impacts include: - The occurrence of isolated tornadoes can hinder the execution of emergency plans during tropical events. - A few places may experience tornado damage, along with power and communications disruptions. - Locations could realize roofs peeled off buildings, chimneys toppled, mobile homes pushed off foundations or overturned, large tree tops and branches snapped off, shallow-rooted trees knocked over, moving vehicles blown off roads, and small boats pulled from moorings. * SURGE: Protect against locally hazardous surge having possible limited impacts across the immediate coast of both Louisiana and Mississippi. Potential impacts in this area 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. Elsewhere across Southeast Louisiana and South Mississippi, little to no impact is anticipated. * WIND: Protect against hazardous wind having possible limited impacts across Southeast Louisiana and South Mississippi. Potential impacts include: - Damage to porches, awnings, carports, sheds, and unanchored mobile homes. Unsecured lightweight objects blown about. - Many large tree limbs broken off. A few trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Some fences and roadway signs blown over. - A few roads impassable from debris, particularly within urban or heavily wooded places. Hazardous driving conditions on bridges and other elevated roadways. - Scattered power and communications outages. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * 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. Do not be a thrill seeker or risk your life for senseless photos or videos. Trees kill people. 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 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 around 5 pm, or sooner if conditions warrant.
