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 on the west bank near Lafitte...Barataria and Crown Point. No inundation expected inside the hurricane protection levees on the east and west banks of the Mississippi River. - Major shoreline erosion. 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 3-6 inches, with locally higher amounts - 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://emergency.louisiana.gov - http://www.slfpae.com/closures.aspx - http://homeport.uscg.mil 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 Jefferson 30.049,-90.260 30.023,-90.180 30.023,-90.121 29.974,-90.125 29.951,-90.138 29.918,-90.135 29.912,-90.108 29.921,-90.074 29.931,-90.062 29.946,-90.059 29.896,-90.008 29.852,-90.029 29.829,-90.068 29.806,-90.072 29.784,-90.060 29.772,-90.075 29.753,-90.066 29.733,-90.064 29.675,-90.016 29.626,-90.003 29.571,-90.158 29.579,-90.165 29.589,-90.152 29.603,-90.156 29.607,-90.152 29.623,-90.161 29.677,-90.157 29.682,-90.188 29.690,-90.198 29.692,-90.228 29.818,-90.167 29.828,-90.175 29.862,-90.240 29.881,-90.244 29.907,-90.269 29.972,-90.280 30.043,-90.280 30.050,-90.280 30.049,-90.260 UGC LAZ061 SAME 022051
