Prepare for limited wind damage. - ACT: Move to safe shelter before the wind becomes hazardous. - POTENTIAL IMPACTS: Limited - 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. * STORM SURGE - LATEST LOCAL FORECAST: Life-threatening storm surge possible - Peak Storm Surge Inundation: The potential for 2-4 feet above ground somewhere within surge prone areas - Window of concern: Wednesday morning until Thursday afternoon - 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: Evacuation efforts and flood preparations should soon be brought to completion before 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: Significant - Areas of inundation from storm surge flooding. Damage to several buildings, mainly near the coast. - Sections of near-shore escape routes and secondary roads become weakened or washed out, especially in usually vulnerable low spots. 3 to 6 feet of inundation is possible outside the hurricane protection levee in marshy areas. No inundation expected inside the hurricane protection levee. - Major shoreline erosion with heavy surf. Strong and numerous rip currents. - 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 around 1 inch - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for localized flooding rain - The flooding rain threat has remained nearly steady from the previous assessment. - PLAN: Emergency plans should include the potential for localized flooding from heavy rain. - PREPARE: Consider protective actions if you are in an area vulnerable to flooding. - ACT: Heed any flood watches and warnings. - POTENTIAL IMPACTS: Limited - Localized rainfall flooding may prompt a few evacuations. - Rivers and tributaries may quickly rise with swifter currents. Small streams, creeks, canals, bayous, and ditches may become swollen and overflow in spots. - Flood waters can enter a few structures, especially in usually vulnerable spots. A few places where rapid ponding of water occurs at underpasses, low-lying spots, and poor drainage areas. Several storm drains and retention ponds become near-full and begin to overflow. Some brief road and bridge closures. * TORNADO - LATEST LOCAL FORECAST: - Situation is somewhat favorable for tornadoes - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: 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 - 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. * FOR MORE INFORMATION: - http://www.slfpae.com/closures.aspx - http://homeport.uscg.mil - http://emergency.louisiana.gov http://www.weather.gov NWSheadline STORM SURGE WATCH REMAINS IN EFFECT VTEC /O.CON.KLIX.SS.A.1013.000000T0000Z-000000T0000Z/ EAS-ORG WXR PIL LIXTCVLIX BLOCKCHANNEL CMAS BLOCKCHANNEL EAS BLOCKCHANNEL NWEM Upper St. Bernard 29.944,-89.839 29.935,-89.819 29.938,-89.775 29.959,-89.728 29.952,-89.717 29.946,-89.714 29.944,-89.719 29.938,-89.746 29.929,-89.746 29.912,-89.744 29.913,-89.750 29.795,-89.852 29.797,-89.871 29.866,-89.910 29.900,-89.927 29.919,-89.984 29.930,-89.980 29.951,-90.010 29.986,-89.991 29.994,-89.973 29.981,-89.953 29.981,-89.941 30.002,-89.906 30.000,-89.890 29.986,-89.880 29.994,-89.870 29.990,-89.860 29.998,-89.864 30.002,-89.857 29.944,-89.839 UGC LAZ064 SAME 022087
