- 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.

prevalent in areas with above ground lines.

above ground somewhere within surge prone areas

UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for storm
surge flooding greater than 1 foot above ground
- PLAN: Plan for storm surge flooding greater than 1 foot
above ground.
- PREPARE: Efforts should now be underway to prepare for
storm surge flooding, especially in low-lying vulnerable
areas.
- ACT: Take actions to protect life and property. Prepare to
leave if evacuation orders are given for your area.
- POTENTIAL IMPACTS: Limited
- Localized inundation with storm surge flooding mainly along
immediate shorelines and in low lying spots, or in areas
farther inland near where higher surge waters move ashore.
- Sections of near shore roads and parking lots become
overspread with surge water. Driving conditions dangerous
in places where surge water covers the road.
- Moderate beach erosion. Heavy surf also breaching dunes,
mainly in usually vulnerable locations. Strong and frequent
rip currents.
- Minor to locally moderate damage to marinas, docks,
boardwalks, and piers. A few small craft broken away from
moorings.

higher amounts
- THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST

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 streams may quickly become swollen with swifter
currents and may overspill their banks in a few places,
especially in usually vulnerable spots. Small streams,
creeks, canals, and ditches may 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.

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.
