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: through 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 outdide the hurricane protection levee on the east bank near Lake Catherine and Lakefront Airport. No inundation expected inside the hurricane protection levees on the east bank and on the parish levee on the west bank. - 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 1-3 inches, with locally higher amounts - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for moderate flooding rain - The flooding rain threat has remained nearly steady from the previous assessment. - PLAN: Emergency plans should include the potential for moderate flooding from heavy rain. Evacuations and rescues are possible. - PREPARE: Consider protective actions if you are in an area vulnerable to flooding. - ACT: Heed any flood watches and warnings. Failure to take action may result in serious injury or loss of life. - POTENTIAL IMPACTS: Significant - 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, bayous, 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. * 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 Orleans 30.154,-89.731 30.157,-89.709 30.173,-89.687 30.162,-89.663 30.150,-89.661 30.156,-89.656 30.149,-89.626 30.141,-89.640 30.119,-89.657 30.109,-89.677 30.076,-89.684 30.060,-89.730 30.049,-89.731 30.026,-89.718 30.022,-89.733 30.044,-89.765 30.045,-89.816 30.034,-89.832 30.002,-89.857 29.998,-89.864 29.990,-89.860 29.994,-89.870 29.986,-89.880 30.000,-89.890 30.002,-89.906 29.981,-89.941 29.981,-89.953 29.994,-89.973 29.986,-89.991 29.951,-90.010 29.930,-89.980 29.919,-89.984 29.900,-89.927 29.866,-89.910 29.870,-89.920 29.893,-89.935 29.902,-89.959 29.905,-89.986 29.890,-89.989 29.896,-90.008 29.946,-90.059 29.931,-90.062 29.921,-90.074 29.912,-90.108 29.918,-90.135 29.951,-90.138 29.974,-90.125 30.023,-90.121 30.030,-90.092 30.026,-90.082 30.032,-90.078 30.034,-90.063 30.032,-90.034 30.053,-90.031 30.037,-90.018 30.046,-89.992 30.085,-89.934 30.148,-89.881 30.154,-89.864 30.154,-89.853 30.135,-89.860 30.101,-89.840 30.104,-89.830 30.097,-89.818 30.106,-89.791 30.144,-89.750 30.175,-89.743 30.154,-89.731 UGC LAZ062 SAME 022071
