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

Tropical storm Harvey remains nearly stationary this evening across
South Texas. The center is located around 10 miles north of Cuero.
Very little movement of Harvey is expected through Tuesday.

The main concern will be catastrophic life-threatening flooding due to
the very slow movement of Harvey. Storm total rainfall amounts between
15 and 25 inches with isolated amounts of 30 inches or more will be
possible generally east of a line from Rockport to Goliad. West of
that area up to highway 16, generally 5 to 10 inches of rainfall will
be possible. West of highway 16, less than 5 inches of rainfall is
expected.

Storm surge inundation up to 3 to 6 feet above ground level between
Port Aransas and Matagorda Bay will continue through Sunday morning.
Storm surge flooding will continue to subside on Sunday.

Winds associated with Harvey will continue to weaken through Sunday.
Tropical storm force winds will likely be ending by midday on Sunday.

Isolated tornadoes will be possible along and to the east of a line
from Rockport to Goliad on Sunday.

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

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
an area east of a line from Rockport to Goliad. Remain well guarded against
life-threatening flood waters having additional devastating impacts.
If realized, these 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, and ditches may become raging rivers. 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:
Potential impacts from the main surge event continue between
Port Aransas and Matagorda Bay. If realized, these impacts 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:
Potential impacts from the main wind event continue across an area
generally northeast of a line from Rockport to Beeville.  If
realized, these impacts include:
    - Damage to porches, awnings, carports, sheds, and unanchored
      mobile homes. Unsecured lightweight objects blown about.
    - Many large tree limbs broken off. A few trees snapped or
      uprooted, but with greater numbers in places where trees are
      shallow rooted. Some fences and roadway signs blown over.
    - A few roads impassable from debris, particularly within urban
      or heavily wooded places. Hazardous driving conditions on
      bridges and other elevated roadways.
    - Scattered power and communications outages.

Elsewhere across SOUTH TEXAS, little to no impact is anticipated.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across an
area east of a line from Rockport to Goliad. If realized,
these 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 SOUTH TEXAS, little to no impact is anticipated.

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

* EVACUATIONS:

RECOVERY PHASE - Do not return to evacuated areas until it is safe.
Listen for the all-clear signal from local authorities.

* OTHER PREPAREDNESS INFORMATION:

Be careful after the storm.  Downed power lines and hanging tree limbs
can pose a threat to life and property.  Be very cautious when traveling
along area roads as there could be significant debris to contend with.
Follow the advice from local officials.
