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.


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:

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.

If you are a visitor and still in the area, listen for the name of
the city or town in which you are staying within local news updates.
Be sure you know the name of the county or parish in which it
resides. Pay attention for instructions from local authorities.

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