POTENTIAL IMPACTS
-----------------

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible significant
impacts across the U.S. Virgin Islands and Puerto Rico. Potential
impacts include:
    - 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.

* WIND:
Protect against hazardous wind having possible limited impacts across
Puerto Rico and the US Virgin Islands. Potential impacts include:
    - Damage to porches, awnings, carports, sheds, and unanchored
      mobile homes. Unsecured lightweight objects blown about.
    - Many large tree limbs broken off. A few trees snapped or
      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.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across Puerto Rico and the US Virgin Islands. Potential impacts
include:
    - 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.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS:
- If you are exceptionally vulnerable to wind or water hazards from
tropical systems, consider voluntary evacuation, especially if being
officially recommended. Relocate to a predetermined shelter or safe
destination.

- If evacuating away from the area or relocating to a nearby shelter,
  leave early before weather conditions become hazardous.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to bring to completion all preparations to protect
life and property in accordance with your emergency plan.

Outside preparations should be wrapped up as soon as possible before
weather conditions completely deteriorate. Any remaining evacuations
and relocations should be expedited before the onset of tropical
storm force wind.

In emergencies it is best to remain calm. Stay informed and focused
on the situation at hand. Exercise patience with those you encounter.
Be a Good Samaritan and helpful to others.

Closely monitor NOAA Weather radio or other local news outlets for
official storm information. Be ready to adapt to possible changes to
the forecast.
