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

Hurricane Delta is about to emerge into the southern Gulf of Mexico
from the Yucatan Peninsula. The environment in the Gulf is expected
to be conducive for strengthening, and the storm should pick up
some strength over the next couple of days as it makes its way towards
the US Gulf Coast. Beyond that, cooler waters and an increase in
shear are expected to cause the storm to weaken, but perhaps more
importantly for Southeast Texas, it will likely cause the wind field
to expand, and has prompted a tropical storm watch for the southeastern
corner of our area.

In addition to the expected larger wind field, there is still some
uncertainty in the precise track of the storm, and any deviance to
the left of the current forecast track will only increase the potential
for more significant impacts to our area than currently expected.
We will have to watch this storm carefully over the next few days.
Preparation actions that do not require significant time, effort, and
money may be good to accomplish now out of an abundance of caution if
you are in the tropical storm watch area.

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

* SURGE:
Prepare for locally hazardous surge having possible limited impacts
across the Galveston Bay area. 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.

* WIND:
Prepare for dangerous wind having possible significant impacts across
the east side of the 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, prepare for hazardous wind having possible limited impacts
across the rest of the Galveston Bay area.

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

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

* EVACUATIONS:
Listen to local official for recommended
preparedness actions, including possible evacuation. If ordered to
evacuate, do so immediately.

* OTHER PREPAREDNESS INFORMATION:
 Now is the time to check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.

When making safety and preparedness decisions, do not focus on the
exact forecast track since hazards such as flooding rain, damaging
wind gusts, storm surge, and tornadoes extend well away from the
center of the storm.

Always heed the advice of local officials and comply with orders that
are issued. Do not needlessly jeopardize your life or the lives of
others.

Closely monitor weather.gov, NOAA Weather Radio and local news
outlets for official storm information. Listen for possible changes
to the forecast.
