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

As of 7 PM CDT, Tropical Storm Harvey was over the Gulf of Mexico
around 50 miles south of Freeport, Texas. Harvey is drifting toward
the east-southeast, and this motion is expected to continue the rest
of tonight, with a northward turn expected on Tuesday. Harvey is
forecast to move inland along the upper Texas coast between Sabine
Pass and Galveston Bay Wednesday morning.

Areas of rain with embedded heavier showers and thunderstorms well
northeast of the center will continue to develop and track northward
across much of the area tonight, with an attendant risk of localized
flash flooding. Isolated tornadoes are also possible, especially
over the coastal counties and parishes.

Tropical storm force winds, mainly in the form of gusts, are expected
to spread across coastal Southeast Texas and Southwest Louisiana by
late Tuesday afternoon as the center nears the coast.

Storm surge of 1 to 3 feet above ground level will be possible along
the coast through Wednesday, primarily around the times of
astronomical high tides.

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

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
Southeast Texas and Southwest Louisiana. Remain well guarded against
life-threatening flood waters having possible 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.

* SURGE:
Potential impacts from the main surge event are now unfolding across
coastal Southeast Texas and coastal Southwest and South Central Louisiana.
Remain well away from locally hazardous surge having possible limited impacts.
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 along rivers and bayous that drain into the Gulf.
    - Sections of roads and parking lots near bodies of water may
      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, and piers.
      A few small craft broken away from moorings.

Elsewhere across SOUTHWEST LOUISIANA AND SOUTHEAST TEXAS, little to
no impact is anticipated.

* WIND:
Potential impacts from the main wind event are now unfolding across
coastal Southeast Texas and Southwest Louisiana. Remain well sheltered
from dangerous wind having possible significant impacts. If
realized, these impacts 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 and access routes
      impassable.
    - Scattered power and communications outages, but more prevalent
      in areas with above ground lines.

Potential impacts from the main wind event are also now unfolding
across Central Louisiana and South Central Louisiana. Remain well
sheltered from hazardous wind 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 possible 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.
