* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
most of Puerto Rico. Remain well guarded against life-threatening flood
waters that are still occurring across the northern half of Puerto Rico
with devastating impacts. If realized, these impacts include:
- Extreme rainfall flooding may prompt numerous evacuations and
- Rivers and tributaries may overwhelmingly overflow their banks
in many places with deep moving water. Small streams, creeks,
canals, arroyos, and ditches may become raging rivers. In
mountain areas, deadly runoff may rage down valleys while
increasing susceptibility to rockslides and mudslides. Flood
control systems and barriers may become stressed.
- Flood waters can enter numerous structures within multiple
communities, some structures becoming uninhabitable or washed
away. Numerous places where flood waters may cover escape
routes. Streets and parking lots become rivers of raging water
with underpasses submerged. Driving conditions become very
dangerous. Numerous road and bridge closures with some weakened
or washed out.
Potential impacts from the main wind event are now unfolding across the
northwest quadrant of Puerto Rico. If realized, these impacts include:
- Structural damage to sturdy buildings, some with complete roof
and wall failures. Complete destruction of mobile homes. Damage
greatly accentuated by large airborne projectiles. Locations
may be uninhabitable for weeks or months.
- Numerous large trees snapped or uprooted along with fences and
roadway signs blown over.
- Many roads impassable from large debris, and more within urban
or heavily wooded places. Many bridges, causeways, and access
- Widespread power and communications outages.
Potential impacts from the main surge event are now unfolding across
the south and west coast of Puerto Rico. If realized, these impacts
- Areas of inundation with storm surge flooding accentuated by
waves. Damage to several buildings, mainly near the coast.
- Sections of near-shore escape routes and secondary roads become
weakened or washed out, especially in usually vulnerable low
