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

Tropical Storm Warning remains in effect for Puerto Rico and the
U.S. Virgin Islands as the Potential Tropical Cyclone Six is
expected to become a Tropical Storm tonight, as it continues to move
west-northwestward at 17 mph across the northeastern Caribbean Sea.
Therefore, tropical storm conditions are likely across the local
islands this evening and continuing through early Wednesday morning.
The external bands of this disturbance are now moving over portions of
the U.S. Virgin Islands and Puerto Rico, including Vieques and Culebra,
producing periods of heavy rain and gusty winds. This disturbance will
continue to bring heavy rains across the islands, with the potential
for life-threatening flash flooding and mudslides, as well as river
flooding through Wednesday, with greatest impact expected across
eastern and southern Puerto Rico. Deteriorating marine and coastal
conditions will continue through Wednesday, with hazardous seas and
life-threatening rip currents. Isolated tornados cannot be ruled out
with the outer bands of this system, especially when the disturbance
moves closer to the islands.

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

* FLOODING RAIN:
Protect against 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.

Protect against locally hazardous rainfall flooding having possible
limited impacts across the U.S. Virgin Islands.

* WIND:
Potential impacts from the main wind event are now unfolding across
across Puerto Rico and the U.S. Virgin Islands. If realized, these
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:

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.
