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

Tropical Storm Harvey is moving slightly faster to the northwest
over the southern Gulf of Mexico. Harvey is expected to continue
to strengthen as it approaches the Texas coast today into Friday.
Tropical storm force winds could approach coastal areas in the
Coastal Bend as early as late tonight.

Heavy rainfall is expected through much of the area with rainfall
totals of 15 to 20 inches east of I37 with isolated amounts around
25 inches possible. Lesser amounts are expected further west and
southwest. These numbers and locations are subject to change
depending on the exact point of landfall along the Texas coast.
Flash flooding is possible with these high rainfall totals. The
heaviest rains are expected to occur Thursday night through Saturday
night and possibly into early next week.

Peak Storm surge inundation is generally expected to be 5 to 7 feet
above ground level along and to the right of where the center
crosses the coast.  Impacts would be felt along the barrier islands
and into the inland bays and waterways. Isolated locations could see
slightly higher inundation.

Tornadoes are possible as rainbands move onshore tonight through Saturday.

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

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across the Coastal Bend, especially east of I37. Potential
impacts include:
    - Moderate rainfall flooding may prompt several evacuations and
      rescues.
    - Rivers and tributaries may quickly become swollen with swifter
      currents and overspill their banks in a few places, especially
      in usually vulnerable spots. Small streams, creeks, canals, and
      ditches overflow.
    - Flood waters can enter some structures or weaken foundations.
      Several places may experience expanded areas of rapid
      inundation at underpasses, low-lying spots, and poor drainage
      areas. Some streets and parking lots take on moving water as
      storm drains and retention ponds overflow. Driving conditions
      become hazardous. Some road and bridge closures.

Prepare for locally hazardous rainfall flooding having possible
limited impacts across the Brush Country.

* SURGE:
Prepare for life-threatening surge having possible extensive impacts
across the Middle Texas Coast and barrier islands. Potential impacts
in this area 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.
    - Major damage to marinas, docks, boardwalks, and piers. Many
      small craft broken away from moorings, especially in
      unprotected anchorages with some lifted onshore and stranded.

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

* WIND:
Prepare for 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.

Also, prepare for dangerous wind having possible significant impacts
across the Brush Country.

* TORNADOES:
Prepare for 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:

instructions. Drivers should not use cell phones while operating
