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.

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
