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

Tropical Storm Fiona is currently located 80 miles southeast of St.
Croix and 150 miles southeast of Ponce, at 16.6 North, 64.9 West. The
forecast is now showing a hurricane crossing from southwestern to
northwestern Puerto Rico tomorrow. Therefore, a Hurricane Warning is in
effect for Puerto Rico, as well as for the local waters. For the U.S.
Virgin Islands, a Tropical Storm Warning and a Hurricane Watch are in
effect. Hurricane conditions are likely for portions of Puerto Rico as
well as for the local waters. Maximum sustained winds are expected to
be as high as near 75 mph with higher gusts up to 90 mph over Puerto
Rico.

The main hazard remains the flooding rainfall that it will bring.
Rainfall totals in southern Puerto Rico are forecast to be 12 to
16 inches, and locally up to 20 inches. Elsewhere, rainfall amounts of
5 to 10 inches are expected, with locally higher amounts. This amount
of rainfall will result in life-threatening flash and urban flooding,
as well as mudslides or rockfalls and river flooding. The greatest
threat for these dangerous flooding conditions is expected between
tonight and Monday.

Deteriorating marine and coastal conditions are also anticipated. Seas
will build to around 18 feet, lasting through the weekend. Winds over
the seas will be around 65 knots with gusts to 85 knots.

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

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts, especially across eastern and southern 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.

Protect against dangerous rainfall flooding having possible
significant impacts across the rest of the region.

* WIND:
Protect against life-threatening wind having possible extensive
impacts across Puerto Rico and the US Virgin Islands. Potential
impacts include:
    - Considerable roof damage to sturdy buildings, with some having
      window, door, and garage door failures leading to structural
      damage. Mobile homes severely damaged, with some destroyed.
      Damage accentuated by airborne projectiles. Locations may be
      uninhabitable for weeks.
    - Many large trees snapped or uprooted along with fences and
      roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. Several bridges, causeways, and
      access routes impassable.
    - Large areas with power and communications outages.

* SURGE:
Protect against locally hazardous surge having possible limited
impacts, mostly along the southern coast of Puerto Rico. Potential
impacts in this area include:
    - Localized inundation with storm surge flooding mainly along
      immediate shorelines and in low-lying spots, or in areas
      farther inland near where higher surge waters move ashore.
    - Sections of near-shore roads and parking lots become overspread
      with surge water. Driving conditions dangerous in places where
      surge water covers the road.
    - Moderate beach erosion. Heavy surf also breaching dunes, mainly
      in usually vulnerable locations. Strong rip currents.
    - Minor to locally moderate damage to marinas, docks, boardwalks,
      and piers. A few small craft broken away from moorings.

* 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:
Now is the time to bring to completion all preparations to protect
life and property in accordance with your emergency plan.

Outside preparations should be wrapped up as soon as possible before
weather conditions completely deteriorate. Any remaining evacuations
and relocations should be expedited before the onset of tropical
storm force wind.

If you are relocating to safe shelter, leave as early as possible. If
heading to a community shelter, become familiar with the shelter
rules before arrival, especially if you have special needs or own a
pet. Take essential items with you from your Emergency Supplies Kit.
Check the latest weather forecast before departing.

Failure to adequately shelter may result in serious injury or loss of
life. Always heed the advice of local officials and comply with any
orders that are issued. Remember, during the storm 9 1 1 Emergency
Services may not be able to immediately respond if conditions are
unsafe. This should be a big factor in your decision making.

Check-in with your emergency points of contact among family, friends,
and workmates. Inform them of your status and well-being. Let them
know how you intend to ride out the storm and when you plan to
check-in again.

Keep cell phones well charged and handy. Also, cell phone chargers
for automobiles can be helpful after the storm. Locate your chargers
and keep them with your cell phone.

If relocating to a nearby shelter or to the home of a family member
or friend, drive with extra caution, especially on secondary roads.
Remember, many bridges and causeways will be closed once higher winds
arrive. Also, if you encounter water covering the road, seek an
alternate route. Always obey official road signs for closures and
detours.

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.
