SITUATION OVERVIEW
------------------
Hurricane Harvey is expected to continue to strengthen as it moves
toward the Texas coast this evening through Friday. Harvey is
currently a Category 1 hurricane and is expected to reach Category
3 status prior to landfall. Tropical storm force winds are expected to
reach coastal areas of the Coastal Bend early Friday morning.
Hurricane force winds will be possible as early as Friday afternoon.
Heavy rainfall is expected through much of the area with rainfall
totals of 15 to 25 inches east of Interstate 37 with isolated amounts
around 35 inches possible. Lesser amounts are expected further west
and southwest. These numbers and locations are subject to change
depending on the exact location of landfall along the Texas coast.
Flash flooding is possible with these high rainfall totals. The
heaviest rains are expected to occur early Friday through Saturday
night and possibly into early next week.
Peak Storm surge inundation is generally expected to be 6 to 12 feet
above ground level from the north entrance of the Padre Island
National Seashore northward to Port O Connor. South of the north
entrance of Padre Island National Seashore storm surge is generally
expected to be 5 to 7 feet above ground level. 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 late tonight through
Saturday, especially north and east of the center of Harvey.
POTENTIAL IMPACTS
-----------------
* SURGE:
Protect against life-threatening surge having possible devastating
impacts across the Middle Texas Coast and Barrier Islands. Potential
impacts in this area include:
- Widespread deep inundation, with storm surge flooding greatly
accentuated by powerful battering waves. Structural damage to
buildings, with many washing away. Damage greatly compounded
from considerable floating debris. Locations may be
uninhabitable for an extended period.
- Near-shore escape routes and secondary roads washed out or
severely flooded. Flood control systems and barriers may become
stressed.
- Extreme beach erosion. New shoreline cuts possible.
- Massive damage to marinas, docks, boardwalks, and piers.
Numerous small craft broken away from moorings with many lifted
onshore and stranded.
Elsewhere across SOUTH TEXAS, little to no impact is anticipated.
* WIND:
Protect against life-threatening wind having possible devastating
impacts across the Coastal Bend and Victoria Crossroads area.
Potential impacts in this area include:
- Structural damage to sturdy buildings, some with complete roof
and wall failures. Complete destruction of mobile homes. Damage
greatly accentuated by large airborne projectiles. Locations
may be uninhabitable for weeks or months.
- Numerous large trees snapped or uprooted along with fences and
roadway signs blown over.
- Many roads impassable from large debris, and more within urban
or heavily wooded places. Many bridges, causeways, and access
routes impassable.
- Widespread power and communications outages.
Also, protect against life-threatening wind having possible
significant to extensive impacts across the Brush Country.
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
devastating impacts across the Coastal Bend and Victoria Crossroads
area. Potential impacts include:
- Extreme rainfall flooding may prompt numerous evacuations and
rescues.
- Rivers and tributaries may overwhelmingly overflow their banks
in many places with deep moving water. Small streams, creeks,
canals, and ditches may become raging rivers. Flood control
systems and barriers may become stressed.
- Flood waters can enter numerous structures within multiple
communities, some structures becoming uninhabitable or washed
away. Numerous places where flood waters may cover escape
routes. Streets and parking lots become rivers of raging water
with underpasses submerged. Driving conditions become very
dangerous. Numerous road and bridge closures with some weakened
or washed out.
Protect against life-threatening rainfall flooding having possible
limited to extensive impacts across the Brush Country.
* TORNADOES:
Protect against 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.
