SITUATION OVERVIEW
------------------
Tropical Storm Nicholas has formed in the Southwestern Gulf of Mexico,
with maximum sustained winds of 40 mph. It is expected to track to the
north-northwest over the next 24 hours and approach the central Texas
Coast within 48 hours as a tropical storm.

This system has the potential to bring widespread and significant
heavy rainfall to portions of Southeast Texas, particularly along the
coast. Rainfall amounts of 5-10 with locally higher totals of 15 inches
are expected through the end of the day on Tuesday. This will result in
flash flooding. A Flash Flood Watch is in effect through Tuesday
afternoon for portions of SE Texas. Additionally, a Storm Surge Watch
is now in effect along the SE Texas Coast. 2-4 feet of storm surge is
expected as the system approaches the coastline early on Tuesday.
This will result in areas coastal flooding, particularly during
high tide. Wind gusts in excess of 50 mph will be possible along
the coast as the storm approaches early on Tuesday, especially
around Matagorda Bay.

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

* WIND:
Prepare for dangerous wind having possible significant impacts along
the SE Texas coast. 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 inland areas of SE Texas.

* SURGE:
Prepare for life-threatening surge having possible significant
impacts along the SE Texas Coast. Potential impacts in
this area include:
    - Areas of inundation with storm surge flooding accentuated by
      waves. Damage to several buildings, mainly near the coast.
    - Sections of near-shore 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, boardwalks, and piers.
      Several small craft broken away from moorings, especially in
      unprotected anchorages.

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

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across SE Texas, including the Houston metro 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.

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

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

If you live in a place particularly vulnerable to flooding, such as
near the ocean or a large inland lake, in a low-lying or poor
drainage area, in a valley, or near an already swollen river, plan to
move to safe shelter on higher ground.

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!

Check on those who may not be fully aware of the situation or who are
unable to make personal preparations.

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