...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH FRIDAY AFTERNOON...

The Flash Flood Watch continues for

* all of the U.S. Virgin Islands and Puerto Rico including
Culebra and Vieques.

* Through Friday afternoon

* Hurricane Maria continues intensifying in an atmosphere
abundant in moisture. It is moving relatively slowly and will
linger over the local area for more than 24 hours spreading
torrential downpours across the islands with even more intense
rainfall in the mountains of the islands it encounters. A
storm total of 12 to 18 inches is expected and isolated areas
may receive 25 inches or more.

* This flooding will lead to rapid rises in all streams and
rivers in the U.S. Virgin Islands and then Puerto Rico. Low
lying roads will be flooded first and many major highways will
be made impassible during the passage of the storm. Mudslides
may also block roads not expected to flood. Any homes in low-
lying areas near rivers and streams will be flooded and
flooding may leave residents with no avenue of escape. Those
in coastal areas may have streams and rivers backed up from
storm surge created by the hurricane. Downed electrical wires
may be able to electrify these waters as an additional hazard.
Some bridges and causeways may also wash away.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding.

This is a very dangerous situation. If you have any doubts about
whether you will be in a flooded area or if your shelter may be
in danger of mudslides, you should seek shelter from Hurricane
Maria early--before winds and rains commence Tuesday.

Preparations for this flooding should be made in advance. The
National Weather Service will continue to monitor this dangerous
situation and keep forecasts and warnings updated.

**EYE OF CATEGORY 5 HURRICANE MARIA MOVING CLOSER TO ST CROIX IN THE
U.S. VIRGIN ISLANDS**

NEW INFORMATION
---------------

* CHANGES TO WATCHES AND WARNINGS:
- None

* CURRENT WATCHES AND WARNINGS:
- A Hurricane Warning is in effect for Central Interior, Culebra,
Eastern Interior, Mayaguez and Vicinity, North Central,
Northeast, Northwest, Ponce and Vicinity, San Juan and
Vicinity, Southeast, Southwest, St Croix, St.Thomas...St.
John...and Adjacent Islands, Vieques, and Western Interior

* STORM INFORMATION:
- About 150 miles southeast of San Juan PR or about 60 miles
southeast of Saint Croix VI
- 17.0N 64.2W
- Storm Intensity 175 mph
- Movement West-northwest or 300 degrees at 10 mph

SITUATION OVERVIEW
------------------

At 8 PM AST Major Hurricane Maria is still yet stronger with sustained
winds of 175 mph, but only very close to the center. It is expected to
continue at this strength with some fluctuations until it encounters
Puerto Rico. It should then begin to weaken. Hurricane conditions are
likely to begin Tuesday night across the USVI, Vieques and Culebra; and
across Puerto Rico Wednesday morning.

Hurricane force winds will likely continue across USVI, Vieques and
Culebra through Wednesday afternoon; and across Puerto Rico through
Wednesday night. These winds will bring catastrophic damage. Severe
injury is possible in less than a strong structure.

Wind speeds atop and on the windward sides of hills and mountains and
on high-rise buildings could be much stronger than the near- surface
winds indicated in the forecast.

Rainfall accumulations across the local islands will depend highly on
the forward speed, but based on the latest forecast, Maria is expected
to produce storm total accumulations of 12 to 18 inches with isolated
amounts of 25 inches or more. Now is the time to complete the
preparations in your emergency plan to secure your home or business.

Storm surges will begin to be noted on the windward sides of the
islands with north and northeast winds arriving first.

POTENTIAL IMPACTS
-----------------

* WIND:
Protect against life-threatening wind having possible devastating
impacts across PUERTO RICO AND THE US VIRGIN ISLANDS. Potential
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
routes impassable.
- Widespread power and communications outages.

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
devastating impacts across PUERTO RICO AND THE US VIRGIN ISLANDS.
Potential impacts include:
- Extreme rainfall flooding may prompt numerous evacuations and
rescues.
- 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.

* SURGE:
Protect against life-threatening surge having possible extensive
impacts across Puerto Rico and the U.S. Virgin Islands, particularly
southeast Puerto Rico and Saint Croix. Potential impacts in
this area include:
- Large areas of deep inundation with storm surge flooding
accentuated by battering waves. Structural damage to buildings,
with several washing away. Damage compounded by floating
debris. Locations may be uninhabitable for an extended period.
- Large sections of near-shore escape routes and secondary roads
washed out or severely flooded. Flood control systems and
barriers may become stressed.
- Severe beach erosion with significant dune loss.
- Major damage to marinas, docks, boardwalks, and piers. Many
small craft broken away from moorings, especially in
unprotected anchorages with some lifted onshore and stranded.

* TORNADOES:
Protect against a dangerous tornado event having possible significant
impacts across PUERTO RICO AND THE US VIRGIN ISLANDS. Potential
impacts include:
- The occurrence of scattered tornadoes can hinder the execution
of emergency plans during tropical events.
- Several places may experience tornado damage with a few spots
of considerable damage, power loss, and communications failures.
- Locations could realize roofs torn off frame houses, mobile
homes demolished, boxcars overturned, large trees snapped or
uprooted, vehicles tumbled, and small boats tossed about.
Dangerous projectiles can add to the toll.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS:
For those under evacuation orders, leave as soon as practical with a
destination in mind. Gas up your vehicle well ahead of time. Be sure
that you take all essential materials from your emergency supplies kit.
Let others know where you are going and when you intend to arrive.

If evacuating the area, stick to prescribed evacuation routes. Look
for additional traffic information on roadway smart signs and listen to
select radio channels for further travel instructions. Drivers should
not use cell phones while operating vehicles.

For those not under evacuation orders, understand that there are
inherent risks to evacuation (such as traffic congestion, accidents,
and driving in bad weather), so evacuate only if necessary. Help keep
roadways open for those that are under evacuation orders.

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.

Do not return to evacuated areas until hazardous winds diminish and
flood waters abate.

* 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.

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 relocating to a nearby shelter or to the home of a family member
or friend, drive with extra caution, especially on secondary roads.
Remember, many bridges and causeways will be closed once higher winds
arrive. Also, if you encounter water covering the road, seek an
alternate route. Always obey official road signs for closures and
detours.

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.
