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

Rainbands from the disturbance are now affecting the U.S. Virgin
Islands and eastern Puerto Rico. These rain bands are producing
periods of heavy rain and gusty winds. Tropical Storm Warning remains
in effect for the local islands as the Potential Tropical Cyclone Six
will likely become a Tropical Storm later today or this evening. This
system continues moving west-northwestward at 18 mph across the
northeastern Caribbean, toward the region. Therefore, tropical storm
conditions are likely across the local islands as early as this
afternoon. This disturbance will also bring heavy rains across the
islands, with the potential for life-threatening flash flooding and
mudslides, as well as river flooding. Eastern and southern Puerto Rico
can expect the greatest impact from this system. Marine and coastal
conditions will deteriorate by this afternoon, continuing through
Wednesday. 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:
Protect against hazardous wind having possible limited impacts across
Puerto Rico and the U.S. Virgin Islands. Potential impacts in this
area 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.

Elsewhere across Puerto Rico and the US Virgin Islands, little to no
impact is anticipated.

* 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.
