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

 A Hurricane Watch has been issued for all the U.S.
 Virgin Islands and the municipalities of Culebra and Vieques in Puerto
 Rico due to possible hurricane conditions in the next 48 hours. As
 the day progresses, the rainbands of Ernesto will gradually increase,
 becoming more frequent and heavier later in the afternoon into the
 evening. Widespread showers will be present tonight and in the early
 morning hours of Wednesday. Tropical storm sustained winds are
 expected across most of the eastern side of Puerto Rico, Culebra,
 Vieques and all the U.S. Virgin Islands. Lingering moisture will
 persist on Wednesday afternoon. Marine and coastal conditions will
 quickly deteriorate today with seas greater than 10 feet and life-
 threatening rip currents, and rough surf conditions.

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

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across all of Puerto Rico and the U.S. Virgin Islands.

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 along steep terrain will result in many
      rockslides and landslides. 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 possible limited
to significant impacts across northwestern sections of Puerto Rico.

* WIND:
Protect against dangerous wind having possible significant impacts
across Puerto Rico and the U.S. Virgin Islands. Potential impacts in
this area 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.

Also, protect against hazardous wind having possible limited impacts
across some northwestern sections of Puerto Rico.

* SURGE:
Protect against locally hazardous surge having possible limited impacts
across all the coastal areas of Puerto Rico and the U.S. Virgin
Islands. Potential impacts in this area 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.

Elsewhere across Puerto Rico and the US Virgin Islands, little to no
impact is anticipated.

* TORNADOES:
Protect against a tornado event having possible limited impacts across
Culebra PR, and the U.S 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.

Elsewhere across Puerto Rico and the US Virgin Islands, little to no
impact is anticipated.

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

* EVACUATIONS:
 Follow the advice of local officials


* 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.
