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

Hurricane Harvey has now weakened to a Category 1 storm. Harvey
will continue to move slowly northwest today across South Texas and
continue to weaken. Harvey will slow down further tonight and
Sunday and the center will likely stall near Cuero.

Hurricane force winds will continue to affect portions of Goliad,
Refugio, and Victoria counties, mainly this morning. Meanwhile,
tropical storm force winds will continue to impact portions of South
Texas generally east of Interstate 37 for most of today.

Catastrophic life-threatening flooding is still expected due to the
heavy rainfall that is expected over the next several days. As much as
20 to 30 inches of rainfall with isolated 40 inches will be possible
across South Texas, mainly east of a line from Rockport to Goliad.
West of that area up to highway 16, generally 5 to 15 inches of
rainfall will be possible with isolated 20 inches possible. West of
highway 16, generally 5 inches or less of rainfall is expected.

Storm surge inundation as high as 6 to 12 feet above ground level will
continue this morning between Port Aransas and Port O'Connor. South of
Port Aransas, 3 to 6 feet above ground level storm surge inundation
will continue this morning. Flooding from storm surge inundation will
gradually subside throughout the day.

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

Mandatory evacuations are in effect for the following areas:

- Port Aransas
- Aransas County
- Refugio County
- San Patricio County
- Victoria County
- Calhoun County
- Eastern Kleberg County (Baffin Bay, Loyola Beach and Rivera Beach
  and areas east)

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

* WIND:
Potential impacts from the main wind event are now unfolding across
the Coastal Bend and Victoria Crossroads area, mainly east of Interstate
37. If realized, these 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.

* SURGE:
Potential impacts from the main surge event are now unfolding across
the Middle Texas Coast. Remain well away from life-threatening
surge having additional devastating impacts. If realized, these
impacts include:
    - Widespread deep inundation, with storm surge flooding greatly
      accentuated by powerful battering waves. Structural damage to
      buildings, with many washing away. Damage greatly compounded
      from considerable floating debris. Locations may be
      uninhabitable for an extended period.
    - Near-shore escape routes and secondary roads washed out or
      severely flooded. Flood control systems and barriers may become
      stressed.
    - Extreme beach erosion. New shoreline cuts possible.
    - Massive damage to marinas, docks, boardwalks, and piers.
      Numerous small craft broken away from moorings with many lifted
      onshore and stranded.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
the Coastal Bend and Victoria Crossroads area, generally east of
Interstate 37. 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.

Remain well guarded against life-threatening flood waters having possible
limited to devastating impacts.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across an area
generally east of a line from Port Aransas to Beeville. 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
----------------------------------
