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

Hurricane Delta has continued to strengthen this evening as it pushes
further northwestward towards the Central Gulf Coast. The system
should maintain its status as a Category 3 Major Hurricane overnight
before a combination of cooler waters and an increase in shear are
expected to cause it to weaken modestly before landfall. This
will also cause the wind field to expand, which has prompted the
issuance of a tropical storm warning along the SE Texas coast.
Furthermore, a hurricane warning remains in effect for the Gulf waters
from 20 to 60 NM out from High Island to Freeport. This is primarily
for the waters closer to 60 NM out from High Island, which may be
clipped by the core of the expanding storm on Friday.

Due to the close approach of this storm, we will have to watch it
carefully as it passes. Those in the watch area should complete preparations
for the impacts of a tropical storm. Even those near the watch area will be well
served to keep an eye on the latest information from the NHC and our
office as the storm makes its crossing of the Gulf of Mexico in order to stay
ahead of any unanticipated changes.

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

* WIND:
Protect against dangerous wind having possible significant impacts
across across the eastern Galveston Bay area. 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.

Also, protect against hazardous wind having possible limited impacts
across across the western Galveston Bay area, and along the Gulf coast to
Sargent.

Elsewhere across Southeast Texas, little to no impact is anticipated.

* SURGE:
Protect against locally hazardous surge having possible limited
impacts across Galveston Bay and Gulf-facing coasts from High
Island to Sargent. Potential impacts in this area 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 Southeast Texas, little to no impact is anticipated.

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across the eastern Galveston Bay area. 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.

Protect against locally hazardous rainfall flooding having possible
limited impacts across the western Galveston Bay area.

Elsewhere across Southeast Texas, little to no impact is anticipated.

* TORNADOES:
Little to no impacts are anticipated at this time
across Southeast Texas.

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

Now is the time to complete all preparations to protect life and
property in accordance with your emergency plan. Ensure you are in a
safe location before the onset of strong winds or possible flooding.

If you are a visitor, be sure to know the name of the city or town in
which you are staying and the name of the county or parish in which
it resides. Listen for these locations in local news updates. Pay
attention for instructions from local authorities.

Closely monitor weather.gov, NOAA Weather radio or local news outlets
for official storm information. Be ready to adapt to possible changes
to the forecast. Ensure you have multiple ways to receive weather
warnings.
