POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across the U.S. Virgin Islands and Puerto Rico.
Potential impacts include:
- Moderate rainfall flooding may prompt several evacuations and
rescues.
- Rivers and tributaries may quickly become swollen with swifter
currents and overspill their banks in a few places, especially
in usually vulnerable spots. Small streams, creeks, canals,
arroyos, and ditches overflow.
- Flood waters can enter some structures or weaken foundations.
Several places may experience expanded areas of rapid inundation
at underpasses, low-lying spots, and poor drainage areas. Some
streets and parking lots take on moving water as storm drains and
retention ponds overflow. Driving conditions become hazardous.
Some road and bridge closures.
* WIND:
Protect against 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.
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:
In emergencies it is best to remain calm. Stay informed and focused on
the situation at hand. Exercise patience with those you encounter. Be
a Good Samaritan and helpful to others.
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.
