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

Tropical Storm Harvey is not forecast to weaken to a depression until
Thursday. Harvey is expected to move very slowly toward the southeast
through Monday and then transition toward the north Tuesday and Wednesday.
Therefore, Harvey will continue to impact South Texas through midweek.

Given the slow movement of Harvey, the main concern will be from the
possibility of catastrophic life-threatening flooding, especially
over the Victoria Crossroads region. Storm total rainfall amounts
between 15 and 25 inches with isolated amounts of 30 inches or more
will be possible through Friday, generally east of a line from Rockport
to Goliad. West of that area to State Road 16, generally 5 to 15 inches
of rainfall will be possible. West of State Road 16, generally less than
5 inches of rainfall is expected.

Storm surge flooding as high as 1 to 3 feet above ground level will
continue in Matagorda Bay. Water levels will continue to slowly fall.

Isolated tornadoes will be possible generally east of a line from Rockport
to Goliad today.

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.

* SURGE:
Potential impacts from the main surge event continue across Matagorda
Bay. If realized, these impacts include:
    - Localized inundation with storm surge flooding mainly along
      immediate shorelines and in low-lying spots, or in areas
      farther inland near where higher surge waters move ashore.
    - Sections of near-shore roads and parking lots become overspread
      with surge water. Driving conditions dangerous in places where
      surge water covers the road.
    - Moderate beach erosion. Heavy surf also breaching dunes, mainly
      in usually vulnerable locations. Strong rip currents.
    - Minor to locally moderate damage to marinas, docks, boardwalks,
      and piers. A few small craft broken away from moorings.

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

* TORNADOES:
Potential impacts from tornadoes are still unfolding across an
area east of a line from Rockport to Goliad. 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
----------------------------------

* EVACUATIONS:

Do not return to evacuated areas until hazardous winds diminish and flood
waters abate.

* 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.
