SITUATION OVERVIEW
------------------
Rain bands associated with Tropical Storm Karen are currently
affecting the U.S. Virgin Islands, Culebra, Vieques and portions of
eastern Puerto Rico. These rainbands will increase in intensity and
frequency during the rest of the day, and the threat of flash
flooding will be high as Karen moves slowly over and to the north of
the islands. Tropical storm force winds are expected to affect
portions of the eastern half of Puerto Rico, Culebra, Vieques and
the U.S. Vrigin Islands during the day. Based on the latest forecast
track, the center of Karen is forecast to move over the southeast
coast of Puerto Rico during the late morning hours, then over the
Atlantic waters during the afternoon hours. Hazardous marine
conditions are expected, mainly over the Caribbean waters and the
waters between the U.S. Virgin Islands and eastern Puerto Rico,
through at least this evening. Also, as Karen moves north of the
islands later this afternoon, marine conditions will quickly
deteriorate through late tonight over the Atlantic waters.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across Puerto Rico and the U.S. Virgin Islands.
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 south and east Puerto Rico as well as
across the U.S. Virgin Islands.
* WIND:
Protect against dangerous wind having possible significant impacts
across Puerto Rico and the U.S. Virgin Islands. Potential impacts in
this area include:
- Damage to porches, awnings, carports, sheds, and unanchored
mobile homes. Unsecured lightweight objects blown about.
- Many large tree limbs broken off. A few trees snapped or
uprooted, but with greater numbers in places where trees are
shallow rooted. Some fences and roadway signs blown over.
- A few roads impassable from debris, particularly within urban
or heavily wooded places. Hazardous driving conditions on
bridges and other elevated roadways.
- Scattered power and communications outages.
* SURGE:
Protect against locally hazardous surge having possible limited impacts
across south and east Puerto Rico, Culebra, Vieques and the U.S. Virgin
Islands. 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.
Elsewhere across PUERTO RICO, little to no impact is anticipated.
* TORNADOES:
Protect against a tornado event having possible limited impacts across
Puerto Rico and the U.S. 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.
Do not return to evacuated areas until hazardous winds diminish and
flood waters abate.
* OTHER PREPAREDNESS INFORMATION:
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.
