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

A Tropical Storm Watch has been issued for the US Virgin Islands and 
Puerto Rico. At 500 PM AST (2100 UTC), the center of Fiona was
located 425 miles east of the Lesser Antilles. On the forecast track,
the center of Fiona is expected to move across the Leeward Islands 
Friday night and early Saturday, and move near the Virgin Islands and 
Puerto Rico late Saturday into Sunday. This system is expected to 
bring rainfall amounts in excess of 8 inches across portions of the 
local islands with life-threatening flash flooding and 
mudslides/rockfalls, as well as river flooding beginning Saturday and 
continuing through at least Sunday. Marine and coastal conditions are 
expected to deteriorate as well starting on Saturday with seas up to 12
feet. Maximum sustained winds near 60 mph (95 km/h) with higher gusts 
are expected across much of the forecast area.

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

* FLOODING RAIN:
Prepare for life-threatening rainfall flooding having possible
extensive impacts particularly across the eastern sectors of Puerto 
Rico. 
Potential impacts include:
    - Major rainfall flooding may prompt many evacuations and rescues.
    - Rivers and tributaries may rapidly overflow their banks in 
      multiple places. Small streams, creeks, canals, arroyos, and 
      ditches may become dangerous rivers. In mountain areas, 
      destructive runoff may run quickly down valleys while 
      increasing susceptibility to rockslides and mudslides. Flood 
      control systems and barriers may become stressed.
    - Flood waters can enter many structures within multiple 
      communities, some structures becoming uninhabitable or washed 
      away. Many places where flood waters may cover escape routes. 
      Streets and parking lots become rivers of moving water with 
      underpasses submerged. Driving conditions become dangerous. 
      Many road and bridge closures with some weakened or washed out.

Prepare for dangerous rainfall flooding having possible significant 
impacts particularly across the eastern sectors of Puerto Rico.

* WIND:
Prepare for dangerous wind having possible significant impacts across 
Puerto Rico and the US Virgin Islands. Potential impacts 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.

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

* TORNADOES:
Prepare for 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:
WATCH/WARNING PHASE - 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.

WATCH/WARNING PHASE - If evacuating away from the area or relocating 
to a nearby shelter, leave early before weather conditions become 
hazardous.


* OTHER PREPAREDNESS INFORMATION:
Now is the time to check your emergency plan and take necessary 
actions to secure your home or business. Deliberate efforts should be 
underway to protect life and property. Ensure that your Emergency 
Supplies Kit is stocked and ready.

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.

Always heed the advice of local officials and comply with any orders 
that are issued. Do not needlessly jeopardize your life or the lives of
others.

Visitors to the area should become familiar with nearby surroundings. 
If you are a visitor, know the name of the county or parish in which 
you are located and where it is relative to current watches and 
warnings. If staying at a hotel, ask the management staff about their 
onsite disaster plan. Listen for evacuation orders, especially 
pertaining to area visitors.

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