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

Tropical Storm Fiona is currently located 65 miles south-southeast of
Ponce, at 17.2 North, 66.1 West. The forecast is now showing a
hurricane crossing over southwestern Puerto Rico late this afternoon or
early this evening, as the storm continues to strengthen. Therefore, a
Hurricane Warning is in effect for Puerto Rico, as well as for the
local waters. Hurricane conditions are likely for portions of Puerto
Rico as well as for the local waters. For the U.S. Virgin Islands, a
Tropical Storm Warning and a Hurricane Watch remain in effect. Maximum
sustained winds are expected to be as high as near 75 mph, with higher
gusts up to 95 mph over Puerto Rico.

The main hazard remains the flooding rainfall that this storm will
bring. Periods of moderate to heavy rainfall have been seen overnight
and this morning Rainfall totals in southern Puerto Rico are forecast
to be 12 to 16 inches, and locally up to 20 to 25 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.

Deteriorated, hazardous 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
80 knots. For the southern and southeastern coasts, water levels of
1 to 3 feet above ground level are expected.

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

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having 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 significant
impacts across the rest of the region.

* WIND:
Protect against life-threatening wind having 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:
Potential impacts from the main surge event are now unfolding across
southern and southeastern Puerto Rico. Remain well away from locally
hazardous surge having limited impacts. If realized, these impacts
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:
Do not return to evacuated areas until hazardous winds diminish and
flood waters abate.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to remain safely sheltered from the storm. Stay inside
and away from windows. Listen for updates and be ready in case you
lose electrical power. Locate your battery powered radio and flashlight
from your Emergency Supplies Kit. Keep these items close.

During the peak of the storm, keep your shoes on and rain gear handy.
Boots and tennis shoes offer the best foot protection if you become
unexpectedly exposed to the elements.

Continue to keep your cell phone well charged for as long as
possible. If you lose power, use it more sparingly and mainly for
personal emergencies and check-ins. Do not overload communications
systems with idle chatter.

Do not venture outside while in the eye of a hurricane. Within the
eye, weather conditions may temporarily improve which can be
misleading. Once the eye passes, the wind will change direction and
return to dangerous speeds. Heavy rain will also return. Be smart and
remain safely hidden from the storm.

Do not be a thrill seeker or risk your life for senseless photos or
videos. Be wise and avoid becoming another statistic.

Be ready to move to the identified safe room if your home or shelter
begins to fail. Quickly move to an interior room on the lowest floor.
Put as many sturdy walls between you and the storm as you can.
Protect your head and body.
