There is a Tropical Storm Warning for all of Puerto Rico and for the
U.S. Virgin Islands. A Hurricane Watch continues in effect for
mainland Puerto Rico. Based on the latest forecast track, tropical
storm force winds are expected to start affecting the offshore
Caribbean waters early this morning. As Tropical Storm Dorian tracks
to the northwest, tropical storm force winds are forecast to affect
St. Croix at around 8 AM, then into south-eastern Puerto Rico and
Vieques at around noon, moving away from the north central Puerto Rico
by Wednesday night. Rain bands associated with Tropical Storm Dorian
will start early this morning and continue through Thursday. Rough and
hazardous seas across the Caribbean waters and Mona Passage are
expected on Wednesday.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across PUERTO RICO AND THE US 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.
* WIND:
Protect against life-threatening wind having possible extensive impacts
across most of Puerto Rico especially the eastern half including
Culebra, Vieques and St. Croix. 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:
Protect against locally hazardous surge having possible limited impacts
across the eastern and southern coasts of Puerto Rico 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.
* 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.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to check your emergency plan and take necessary
actions to secure your home or business. Deliberate efforts should be
underway to protect life and property. Ensure that your Emergency
Supplies Kit is stocked and ready.
When making safety and preparedness decisions, do not focus on the
exact forecast track as there are inherent forecast uncertainties
which must be taken into account.
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.
