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

A Tropical Storm Watch remains in effects for the US Virgin Islands
and Puerto Rico, and tropical storm conditions are possible as early
as Saturday morning for eastern-most sections. At 2 AM AST (06 UTC),
the center of Tropical Storm Fiona was located about 285 miles east-
southeast of the Lesser Antilles. The forecast is on track, and no
changes have been introduced. On the forecast track, the center of
Fiona is forecast to move through the Leeward Islands tonight and
early Saturday, and move near or over the Virgin Islands and Puerto
Rico late Saturday night into Sunday. Showers and thunderstorms from
Fiona will generate rainfall totals in excess of 8 inches across
portions of the local islands with life-threatening flash and urban
flooding, along with mudslides/rockfalls and river flooding beginning
on Saturday and continuing through at least Monday. Marine and coastal
conditions are expected to deteriorate as well starting as early as
this morning with building seas up to 12 feet. Maximum sustained winds
near 60 mph (95 km/h) with higher gusts are expected across portions 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 in this area
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 waterspouts having possible limited impacts across the
local waters of Puerto Rico and the US Virgin Islands. Potential
impacts include:
    - The occurrence of isolated waterspouts.
