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

Tropical Storm Nicholas has reformed farther north across the western
Gulf of Mexico and is moving north-northwest at 12 mph. Nicholas will
pass near or just off the lower Texas coast this morning, before making
landfall along the middle Texas coast tonight or early Tuesday. The
biggest impact expected across the lower Texas coast continues to be
the potential for flooding this evening into Monday night. A Flash
Flood Watch has been issued for Cameron, Willacy, and Kenedy counties
with rainfall of 2 to 4 inches and locally higher amounts. Tropical
Storm force wind gusts are possible Monday morning into Monday evening
across the lower Texas coast, including South Padre Island and Boca
Chica. Storm surge is expected to generally peak at 2 to 3 feet, with
an isolated 4 feet Monday afternoon into Monday night, with coastal
flooding and beach erosion possible.

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

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across coastal to central portions of Deep South
Texas. Potential impacts include:
    - Moderate rainfall flooding may prompt several evacuations and
      rescues.
    - Rivers and tributaries may quickly become swollen with swift
      currents and overspill their banks in a few places, especially
      in usually vulnerable spots. Small streams, creeks, canals,
      arroyos, 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 western portions of Deep South Texas.

* WIND:
Protect against hazardous wind having possible limited impacts across the
coastal areas. Potential impacts in this area 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.

Elsewhere across The Rio Grande Valley and Deep South Texas, little
to no impact is anticipated.

* SURGE:
Protect against life-threatening surge having possible significant
impacts across the lower 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. Exposed parking lots become overspread with surge water.
    - Major beach erosion with heavy surf breaching dunes. New
      shoreline cuts possible. Strong and numerous rip currents.
    - Moderate damage to marinas, docks, boardwalks, and piers.
      Several small craft broken away from moorings, especially in
      unprotected anchorages.

Also, protect against locally hazardous surge having possible limited
impacts across inland areas along the Laguna Madre.

* TORNADOES:
Little to no impacts are anticipated at this time across The Rio
Grande Valley and Deep South 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 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.

Keep cell phones well charged. Cell phone chargers for automobiles can
be helpful, but be aware of your risk for deadly carbon monoxide
poisoning if your car is left idling in a garage or other poorly
ventilated area.

Storm surge is the leading killer associated with tropical storms and
hurricanes! Make sure you are in a safe area away from the surge zone.
Even if you are not in a surge-prone area, you could find yourself
cutoff by flood waters during and after the storm. Heed evacuation
orders issued by the local authorities.

Rapidly rising flood waters are deadly. If you are in a flood-prone
area, consider moving to higher ground. Never drive through a flooded
roadway. Remember, turn around don't drown!

If in a place that is vulnerable to high wind, such as near large
trees, a manufactured home, upper floors of a high-rise building, or on
a boat, consider moving to a safer shelter before the onset of strong
winds or flooding.

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.
