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

Tropical Storm Harvey is expected to drift slowly toward the southeast
through Tuesday back into the coastal waters of the Middle and Upper
Texas coast, then move toward the north to northeast into Southeast Texas
Wednesday. Thus, Harvey will continue to impact South Texas and
adjacent coastal waters through Tuesday.

Given the slow movement of Harvey, the primary concern will be the
possibility of catastrophic life-threatening flooding. Additional
storm total rainfall amounts 5 to 10 inches with isolated higher
amounts will be possible generally east of a line from Rockport to
Goliad. West of that region, generally less than 5 inches of rainfall
is expected.

Storm surge flooding as high as 1 to 2 feet above ground level will
continue in Matagorda, Lavaca, and San Antonio Bays.

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

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
east of a line from Rockport to Goliad. If realized, these impacts include:
    - Major rainfall flooding may prompt many evacuations and rescues.
    - Rivers and tributaries may rapidly overflow their banks in
      multiple places. Small streams, creeks, canals, and ditches may
      become dangerous rivers. Flood control systems and barriers may
      become stressed.
    - Flood waters can enter many structures within multiple
      communities, some structures becoming uninhabitable or washed
      away. Many places where flood waters may cover escape routes.
      Streets and parking lots become rivers of moving water with
      underpasses submerged. Driving conditions become dangerous.
      Many road and bridge closures with some weakened or washed out.

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

* WIND:
Potential impacts from the main wind event continue across
the Aransas, Goliad, Victoria, Refugio, and Calhoun counties.
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.


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:

When clearing out fallen trees, be careful with chain saws and axes.
Always wear protective gear and keep others at a safe distance. Use
these tools according to operating manuals and safety instruction.
Leaning trees and those which have fallen on roof tops can be
especially challenging. If you are not in good health or unsure about
what you are doing, have someone else with tree cutting experience do
the job. Never cut trees without a partner.

If using a generator, avoid carbon monoxide poisoning by following
instructions by the manufacturer. Make sure that the generator is run
in a well ventilated space.

Problems with sewer backups can further contaminate standing flood
waters. Keep children away. Also, listen for boil water alerts
relative to communities whose tap water may have become non-potable.
