Prepare for significant wind damage. - ACT: Move to safe shelter before the wind becomes hazardous. - POTENTIAL IMPACTS: Significant - Some damage to roofing and siding materials, along with damage to porches, awnings, carports, and sheds. A few buildings experiencing window, door, and garage door failures. Mobile homes damaged, especially if unanchored. Unsecured lightweight objects become dangerous projectiles. - Several large trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Several fences and roadway signs blown over. - Some roads impassable from large debris, and more within urban or heavily wooded places. A few bridges, causeways, and access routes impassable. - Scattered power and communications outages, but more prevalent in areas with above ground lines. * STORM SURGE - LATEST LOCAL FORECAST: Life-threatening storm surge possible - Peak Storm Surge Inundation: The potential for 4-6 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. - 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 2-4 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://emergency.louisiana.gov http://www.weather.gov NWSheadline STORM SURGE WARNING REMAINS IN EFFECT... ...TROPICAL STORM WARNING REMAINS IN EFFECT VTEC /O.CON.KLIX.TR.W.1013.000000T0000Z-000000T0000Z/ EAS-ORG WXR PIL LIXTCVLIX BLOCKCHANNEL CMAS BLOCKCHANNEL EAS BLOCKCHANNEL NWEM Lower Terrebonne 29.557,-90.574 29.535,-90.568 29.531,-90.551 29.514,-90.537 29.505,-90.537 29.462,-90.486 29.454,-90.468 29.417,-90.447 29.367,-90.385 29.349,-90.380 29.325,-90.387 29.305,-90.377 29.287,-90.383 29.282,-90.384 29.264,-90.397 29.256,-90.404 29.247,-90.403 29.243,-90.403 29.242,-90.405 29.239,-90.409 29.310,-90.423 29.272,-90.476 29.262,-90.550 29.209,-90.518 29.115,-90.648 29.074,-90.859 29.151,-90.959 29.188,-91.094 29.216,-91.129 29.221,-91.200 29.248,-91.279 29.251,-91.307 29.299,-91.335 29.324,-91.352 29.332,-91.353 29.333,-91.346 29.330,-91.341 29.309,-91.338 29.311,-91.332 29.310,-91.307 29.306,-91.309 29.310,-91.295 29.321,-91.291 29.330,-91.277 29.361,-91.267 29.374,-91.232 29.353,-91.236 29.331,-91.220 29.310,-91.194 29.323,-91.176 29.330,-91.174 29.329,-91.162 29.267,-91.170 29.255,-91.151 29.248,-91.132 29.258,-91.118 29.271,-91.122 29.281,-91.134 29.306,-91.120 29.317,-91.122 29.322,-91.129 29.333,-91.128 29.342,-91.136 29.344,-91.151 29.356,-91.153 29.373,-91.200 29.393,-91.205 29.393,-91.223 29.421,-91.212 29.436,-91.221 29.445,-91.259 29.464,-91.261 29.479,-91.274 29.511,-91.265 29.532,-91.272 29.542,-91.267 29.545,-91.257 29.551,-91.235 29.562,-91.223 29.576,-91.225 29.584,-91.219 29.608,-91.184 29.609,-91.175 29.597,-91.173 29.593,-91.162 29.604,-91.151 29.603,-91.139 29.609,-91.139 29.608,-91.121 29.617,-91.117 29.627,-91.083 29.641,-91.070 29.574,-90.929 29.547,-90.763 29.557,-90.574 UGC LAZ066 SAME 022109
