SITUATION OVERVIEW

A Tropical Storm Watch has been issued for the US Virgin Islands and

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

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.

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