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: Localized storm surge possible
- Peak Storm Surge Inundation: The potential for 1-3 feet
above ground somewhere within surge prone areas
- Window of concern: Monday afternoon until Tuesday afternoon

surge flooding greater than 1 foot above ground
- The storm surge threat has remained nearly steady from the
previous assessment.
- PLAN: Plan for storm surge flooding greater than 1 foot
above ground.
- PREPARE: Complete preparations for storm surge flooding,
especially in low-lying vulnerable areas, before conditions
become unsafe.
- ACT: Leave immediately 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.

action will likely result in serious injury or loss of life.

- POTENTIAL IMPACTS: Extensive
- Major rainfall flooding may prompt many evacuations and
rescues.
- Rivers and tributaries may rapidly overflow their banks in
multiple places. Small streams, creeks, canals, arroyos,
and ditches may become dangerous rivers. In mountain areas,
destructive runoff may run quickly down valleys while
increasing susceptibility to rockslides and mudslides.
Flood control systems and barriers may become stressed.
- Flood waters can enter many structures within multiple
communities, some structures becoming uninhabitable or
washed away. Many places where flood waters may cover
escape routes. Streets and parking lots become rivers of
moving water with underpasses submerged. Driving conditions
become dangerous. Many road and bridge closures with some
weakened or washed out.

urged to relocate to safe shelter before hazardous weather
arrives.
- ACT: Listen for tornado watches and warnings. If a tornado
warning is issued, be ready to shelter quickly.

- POTENTIAL IMPACTS: Significant
- The occurrence of scattered tornadoes can hinder the
execution of emergency plans during tropical events.
- Several places may experience tornado damage with a few
spots of considerable damage, power loss, and
communications failures.
- Locations could realize roofs torn off frame houses, mobile
homes demolished, boxcars overturned, large trees snapped
or uprooted, vehicles tumbled, and small boats tossed
about. Dangerous projectiles can add to the toll.
