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

As of 1 AM CDT, Tropical Storm Harvey was over the Gulf of Mexico
about 40 miles south-southwest of Cameron, Louisiana. Harvey is moving
toward the northeast at around 7 mph. A north-northeastward motion is
expected later this morning, and this general motion should continue
through tonight.  On this forecast track, the center of Harvey is expected
to move inland along the Cameron Parish coastline near Cameron later this
morning.

Widespread catastrophic flooding will continue across southeast Texas
with the potential for flash flooding to increase across portions of
southwest and south central Louisiana through Wednesday. Areas of rain
with embedded heavier showers and thunderstorms north and northeast of
the center will continue to develop and track northward across the
area today. Isolated tornadoes are also be possible, especially over
the coastal counties and parishes.

Tropical storm force winds, mainly in the form of gusts, are now spreading
across coastal Southeast Texas and Southwest Louisiana as the center nears
the coast.

Storm surge of 2 to 4 feet above ground level can be expected along
the coast from Holly Beach east to Morgan City, with surge of 1 to
3 feet above ground level expected west of Holly Beach through
Wednesday. Surge will be highest around the times of astronomical high
tides.

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

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
East Texas and Southwest Louisiana. Remain well guarded against
life-threatening flood waters having additional catastrophic impacts.
If realized, these 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.

Potential impacts from the flooding rain are still unfolding across
Central and South Central Louisiana. Remain well guarded against
life-threatening flood waters having possible limited to devastating
impacts.

* WIND:
Potential impacts from the main wind event are now unfolding across
SOUTHWEST LOUISIANA AND SOUTHEAST TEXAS. Remain well sheltered from
hazardous wind having additional limited impacts. 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.

* SURGE:
Potential impacts from the main surge event are now unfolding across
Coastal Louisiana. Remain well away from life-threatening
surge having possible significant impacts. If realized, these impacts
include:
    - Areas of inundation with storm surge flooding accentuated by
      waves. Damage to non-elevated structures is possible.
    - Sections of 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, and piers. Several small
      craft broken away from moorings, especially in unprotected
      anchorages.

Potential impacts from the main surge event are also now unfolding
across Coastal Southeast Texas. Remain well away from locally
hazardous surge having possible limited impacts.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across SOUTHWEST
LOUISIANA AND SOUTHEAST TEXAS. Remain well braced against a tornado
event having additional limited impacts. 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.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS:

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

* OTHER PREPAREDNESS INFORMATION:

Do not be a thrill seeker or risk your life for senseless photos or
videos. Be wise and avoid becoming another statistic.

Continue to keep your cell phone well charged for as long as
possible. If you lose power, use it more sparingly and mainly for
personal emergencies and check-ins. Do not overload communications
systems with idle chatter.
