outward up to 35 miles from the center. A Tropical Storm Warning

storm force winds and periods of heavy rain, with the potential for
life-threatening flash flooding and mudslides, as well as rapid river
flooding. Hazardous marine and coastal conditions are also expected,
beginning as early as Sunday morning. First rainbands from Grace will
arrive by Sunday morning, becoming more frequent and heavier Sunday
afternoon through Sunday night. A Flash Flood Watch is in effect from
Sunday through Monday evening. Stay tuned for additional updates.

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 dangerous wind having possible significant impacts
across the U.S. Virgin Islands and Puerto Rico. Potential impacts in
this area include:
    - Some damage to roofing and siding materials, along with damage
      to porches, awnings, carports, and sheds. A few buildings
      experiencing window, door, and garage door failures. Mobile
      homes damaged, especially if unanchored. Unsecured lightweight
      objects become dangerous projectiles.
    - Several large trees snapped or uprooted, but with greater
      numbers in places where trees are shallow rooted. Several
      fences and roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. A few bridges, causeways, and access
      routes impassable.
    - Scattered power and communications outages, but more prevalent in
      areas with above ground lines.

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.
