SITUATION OVERVIEW
------------------
Fiona's outer bands are producing periods of heavy rains and gusty
winds across the U.S. Virgin Islands, Puerto Rico and surrounding
waters. Showers and thunderstorms will become more frequent as Fiona
approaches the islands. At 2 AM AST (06Z UTC), the center of Tropical
Storm Fiona was located about 260 miles southeast of San Juan, or
about 160 miles southeast of St. Croix. On the latest track forecast,
the center of Fiona is expected to move near or just south of the U.S.
Virgin Islands and Puerto Rico today and Sunday. The main threat with
this system remains the rainfall, which will persist through early
next week, with overall, multi-day totals in excess of 4-8 inches for
some areas around the local islands, including a forecast for 8 to 12
inches for southeastern and southwestern Puerto Rico. This amount of
rainfall will result in life-threatening flash and urban flooding, as
well as mudslides or rockfalls and river flooding. The greatest threat
for these dangerous flooding conditions is expected between today and
Monday. Marine and coastal conditions are deteriorating, and seas will
build to around 15 feet through the weekend. Maximum sustained winds
to near 60 mph with higher gusts of 75 or more are expected for the
islands.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Prepare for life-threatening rainfall flooding having possible
extensive impacts, especially across eastern and southern 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.
Protect against dangerous rainfall flooding having significant impacts
across the rest of the region.
* WIND:
Protect against dangerous wind having 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.
* 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.
* SURGE:
Little to no impacts are anticipated at this time across Puerto Rico
and the US Virgin Islands. Potential impacts in this area include:
- 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.
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.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to bring to completion all preparations to protect
life and property in accordance with your emergency plan.
Outside preparations should be wrapped up as soon as possible before
weather conditions completely deteriorate. Any remaining evacuations
and relocations should be expedited before the onset of tropical
storm force wind.
If you are relocating to safe shelter, leave as early as possible. If
heading to a community shelter, become familiar with the shelter
rules before arrival, especially if you have special needs or own a
pet. Take essential items with you from your Emergency Supplies Kit.
Check the latest weather forecast before departing.
Failure to adequately shelter may result in serious injury or loss of
life. Always heed the advice of local officials and comply with any
orders that are issued. Remember, during the storm 9 1 1 Emergency
Services may not be able to immediately respond if conditions are
unsafe. This should be a big factor in your decision making.
Check-in with your emergency points of contact among family, friends,
and workmates. Inform them of your status and well-being. Let them
know how you intend to ride out the storm and when you plan to
check-in again.
Keep cell phones well charged and handy. Also, cell phone chargers
for automobiles can be helpful after the storm. Locate your chargers
and keep them with your cell phone.
If you are a visitor and still in the area, listen for the name of
the city or town in which you are staying within local news updates.
Be sure you know the name of the county or parish in which it
resides. Pay attention for instructions from local authorities.
Closely monitor NOAA Weather radio or other local news outlets for
official storm information. Be ready to adapt to possible changes to
the forecast.
