SITUATION OVERVIEW

Tropical Depression Harvey continues to move very slowly over the
southern Gulf of Mexico. Harvey is expected to continue to
strengthen as it approaches the Texas coast Thursday into Friday.
Tropical storm force winds could approach coastal areas in the
Coastal Bend as early as Friday morning.

Heavy rainfall is expected through much of the area with rainfall
totals of 6 to 12 inches possible across the southern Coastal Bend
and 10 to 15 inches possible across the northern Coastal Bend and
Victoria Crossroads. Isolated higher amounts are possible. Lesser
amounts are expected further west. 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 will occur Thursday night through
Saturday.

Peak Storm surge inundation is generally expected to be 4 to 6 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 Thursday night
through Saturday.

POTENTIAL IMPACTS

• FLOODING RAIN:
  Prepare for dangerous rainfall flooding having possible significant
  impacts across the Coastal Bend. 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.

SURGE:
Prepare for life-threatening surge having possible significant
impacts across across the middle Texas coast and barrier islands. 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.

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.

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.

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

PRECAUTIONARY/PREPAREDNESS ACTIONS

• EVACUATIONS:
  If you are exceptionally vulnerable to wind or
  water hazards from tropical systems, consider voluntary evacuation.
  Relocate to a predetermined shelter or safe destination.

OTHER PREPAREDNESS INFORMATION:
Padre Island National Seashore will close its beaches to driving at
noon on Thursday.

Texas A & M – Corpus Christi has issued a mandatory evacuation for its
campus. All students and residents must vacate the campus by 7 am on
Thursday.

Texas A & M – Kingsville will be closing at 5 pm Thursday and will
