POTENTIAL IMPACTS

WIND

  • 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.

RAIN

  • 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, arroyos, 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.

TORNADOES

  • 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 boats pulled from moorings.

CURRENT POWER OUTAGES: For the state of Alabama, there are over 134,000 customers without power at this point. If you add that to Louisiana and Mississippi’s combined total of over 753,000, the grand total affected by Zeta is over 887,000 customers.
