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 10 to 15 inches possible along the middle Texas coast and
Victoria Crossroads. 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
-----------------
* WIND:
Prepare for dangerous wind having possible significant impacts across
the Coastal Bend. Potential impacts in this area include:
- Some damage to roofing and siding materials, along with damage
to porches, awnings, carports, and sheds. A few buildings
experiencing window, door, and garage door failures. Mobile
homes damaged, especially if unanchored. Unsecured lightweight
objects become dangerous projectiles.
- Several large trees snapped or uprooted, but with greater
numbers in places where trees are shallow rooted. Several
fences and roadway signs blown over.
- Some roads impassable from large debris, and more within urban
or heavily wooded places. A few bridges, causeways, and access
routes impassable.
- Scattered power and communications outages, but more prevalent
in areas with above ground lines.
* 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 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.
* TORNADOES:
Prepare for a tornado event having possible limited impacts across the
Coastal Bend. 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

water hazards from tropical systems, consider voluntary evacuation.
