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.

and rescues.
- Rivers and tributaries may overwhelmingly overflow their
banks in many places with deep moving water. Small streams,
creeks, canals, arroyos, and ditches may become raging
rivers. In mountain areas, deadly runoff may rage down
valleys while increasing susceptibility to rockslides and
mudslides. Flood control systems and barriers may become
stressed.
- Flood waters can enter numerous structures within multiple
communities, some structures becoming uninhabitable or
washed away. Numerous places where flood waters may cover
escape routes. Streets and parking lots become rivers of
raging water with underpasses submerged. Driving conditions

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,
