SITUATION OVERVIEW
------------------
Tropical Storm Dorian has been upgraded to a category 1 Hurricane.
Dorian was located just over St. Thomas just before 2 PM AST. Hurricane
storm force winds can affect the northern U.S. Virgin Islands and
Culebra during the next hour. Tropical tropical storm force winds are
expected to continue between the U.S. Virgin Islands and eastern Puerto
Rico through the afternoon hours with possible hurricane force wind
gusts as Dorian tracks to the northwest. Dorian is expected to move
over the local Atlantic waters during the late afternoon or early
evening hours and exit the region by early Thursday morning. Rain bands
will continue to increase across the U.S. Virgin Islands and across
Puerto Rico through the rest of the day.
POTENTIAL IMPACTS
-----------------
* WIND:
Potential impacts from the main wind event are now unfolding across St.
Thomas, St. John and Culebra. Remain well sheltered from life-
threatening wind having additional extensive impacts. If realized,
these 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.
Potential impacts from the main wind event are also now unfolding
across the rest of the U.S. Virgin Islands and the east coast of Puerto
Rico. Remain well sheltered from dangerous wind having possible
limited to significant impacts.
* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across the
U.S. Virgin Islands and across the eastern, central and southern
sections of Puerto Rico. Remain well guarded against life- threatening
flood waters having additional extensive impacts. If realized, these
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.
Potential impacts from the flooding rain are still unfolding across
the rest of the northern Puerto Rico. Remain well guarded against
dangerous flood waters having possible significant impacts.
* SURGE:
Potential impacts from the main surge event are now unfolding across
across the coastal areas of the U.S. Virgin Islands and eastern Puerto
Rico, but especially across St. Thomas, St. John, Culebra and Vieques.
Remain well away from locally hazardous surge having possible limited
impacts across eastern and northern Puerto Rico. 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:
Potential impacts from tornadoes are still unfolding across PUERTO RICO
AND THE US VIRGIN ISLANDS. Remain well braced against a tornado event
having possible limited impacts. If realized, these 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:
Do not venture outside while in the eye of the storm. 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.
