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

Hurricane Hanna continues to intensify as it approaches the lower
Texas coast. Rain bands from the hurricane have been reaching the
coast for the last several hours. Hanna may strengthen slightly until
it makes landfall later today.

Flooding rain continues to be a primary concern on the impact of
Hanna. Potential rainfall totals remain at 5 to 10 inches for the
southern Coastal Bend and southern Brush Country with localized higher
amounts near 15 inches possible. Farther north and west rainfall
totals decrease to 3 to 6 inches. Moderate to major coastal flooding
is also expected as the storm approaches with inundation of 3 to
5 feet in lower areas along the immediate waterfront. Brief tornadoes
will also be possible through the Coastal Bend and Brush Country as
Hanna's rain bands move ashore.

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

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across South Texas. 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. 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.

* SURGE:
Protect against life-threatening surge having possible significant
impacts across the lower and middle Texas coast. Potential impacts
in this area include:
    - 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
      spots.
    - Major beach erosion with heavy surf breaching dunes. Strong and
      numerous rip currents.
    - Moderate damage to marinas, docks, boardwalks, and piers.
      Several small craft broken away from moorings, especially in
      unprotected anchorages.

* WIND:
Protect against life-threatening wind having possible extensive
impacts across the Coastal Bend. Potential impacts in this area
include:
    - Considerable roof damage to sturdy buildings, with some having
      window, door, and garage door failures leading to structural
      damage. Mobile homes severely damaged, with some destroyed.
      Damage accentuated by airborne projectiles. Locations may be
      uninhabitable for weeks.
    - Many large trees snapped or uprooted along with fences and
      roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. Several bridges, causeways, and
      access routes impassable.
    - Large areas with power and communications outages.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across South Texas. 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.

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

* EVACUATIONS:
Listen to local official for recommended
preparedness actions, including possible evacuation. If ordered to
evacuate, do so immediately.

For those not under evacuation orders, assess
the risk from wind, falling trees, and flooding at your location. If
you decide to move, relocate to a safer location nearby. If you do
not relocate, help keep roadways open for those under evacuation
orders.

* OTHER PREPAREDNESS INFORMATION:

Storm surge is the leading killer associated with tropical storms and
hurricanes! Make sure you are in a safe area away from the surge
zone. Even if you are not in a surge-prone area, you could find
yourself cutoff by flood waters during and after the storm. Heed
evacuation orders issued by the local authorities.

Rapidly rising flood waters are deadly. If you are in a flood-prone
area, consider moving to higher ground. Never drive through a flooded
roadway. Remember, turn around don't drown!

If a Tornado Warning is issued for your area, be ready to shelter
quickly, preferably away from windows and in an interior room not
prone to flooding. If driving, scan the roadside for quick shelter
options.

If in a place that is vulnerable to high wind, such as near large
trees, a manufactured home, upper floors of a high-rise building, or
on a boat, consider moving to a safer shelter before the onset of
strong winds or flooding.

Closely monitor weather.gov, NOAA Weather radio or local news outlets
for official storm information. Be ready to adapt to possible changes
to the forecast. Ensure you have multiple ways to receive weather
warnings.
