SITUATION OVERVIEW
------------------

A Tropical Storm Watch is in effect for Puerto Rico and the U.S.
Virgin Islands, as the tropical disturbance currently located about 135
miles southeast of Guadeloupe could develop and strengthen into a
tropical storm while it moves west-northwestward at 10 to 15 mph across
the northeastern Caribbean Sea. Thus, tropical storm conditions are
likely across the local islands as early as Tuesday afternoon. This
disturbance is also expected to bring heavy rains across the islands
with the potential for life-threatening flash flooding and mudslides,
as well as river flooding, with highest impact expected across portions
of eastern and southern Puerto Rico. Deteriorating marine and coastal
conditions are expected by Tuesday afternoon and continuing through
Wednesday.

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

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across eastern and southern 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.

Prepare for locally hazardous rainfall flooding having possible
limited impacts across the U.S. Virgin Islands.

* WIND:
Prepare for 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.

* SURGE:
Little to no additional impacts are anticipated at this time across
Puerto Rico and the US Virgin Islands.

* TORNADOES:
Little to no additional impacts are anticipated at this time across
Puerto Rico and the US Virgin Islands.

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:

When making safety and preparedness decisions, do not focus on the
exact forecast track as there are inherent forecast uncertainties
which must be taken into account.

If you live in a place particularly vulnerable to flooding, such as
near the ocean or a large inland lake, in a low lying or poor drainage
area, in a valley or canyon, or near an already swollen river, plan to
move to safe shelter on higher ground

Closely monitor NOAA Weather Radio or other local news outlets for
official storm information. Listen for possible changes to the
forecast.
