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

Tropical Storm Harvey has become stationary west of Cuero in DeWitt
County to the northwest of Victoria. Tropical Storm Warning remains
in effect for the Coastal Bend, Victoria Crossroads, and the Middle
Texas coastal waters. Tropical Storm Harvey will remain nearly
stationary tonight then drift south to southeast back toward the
Middle Texas coast Sunday through Tuesday.

Tropical storm force winds will continue to impact portions of South
Texas generally east of Highway 281 and over the coastal waters for
tonight.

Catastrophic life-threatening flooding is still expected due to the
heavy rainfall that is expected over the next several days. Storm
total rainfall accumulations will be as much as 15 to 30 inches of
rainfall with isolated 40 inches across eastern portions of South
Texas, mainly east of a line from Beeville to Port Aransas. West of
that area up to Highway 16, generally 5 to 15 inches of rainfall will
be possible. West of Highway 16, generally 5 inches or less of
rainfall is expected.

Storm surge inundation will remain from 4 to 7 feet from Port Aransas
to Port Lavaca tonight. Flooding from storm surge inundation will
gradually subside by Sunday. South of Port Aransas, offshore winds
have provided a significant decrease in tide levels.

Isolated tornadoes will be possible along and to the east of a line
from Beeville to Port Aransas tonight.

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

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
the Coastal Bend and Victoria Crossroads area, mainly east of Highway
16. Remain well guarded against life-threatening flood waters having
possible catastrophic 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:
Impacts from the surge event are now unfolding across the Middle Texas
coast between Port Aransas and Port Lavaca. Tide inundation levels
will continue to be from 4 to 7 feet AGL. Remain well away from
life-threatening surge having additional extensive impacts. If
realized, these impacts 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.

* WIND:
Potential impacts from the main wind event are now unfolding across
the Victoria Crossroads into the Coastal Bend. If realized, these
impacts 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.

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

* TORNADOES:
Potential impacts from tornadoes are still unfolding across the
Victoria Crossroads. 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.
