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

Nicholas has produced gusts beyond the hurricane threshold over
Matagorda Bay, and is being designated Hurricane Nicholas as it nears
landfall on the Central Texas Coast later tonight. No further
strengthening is anticipated, and the storm is forecast to make
landfall as a Category 1 hurricane. Because of this, the hurricane
watch from Port O'Connor to Freeport is being upgraded to a hurricane
warning. Far inland, as confidence has increased in the track of the
storm, the tropical storm watch for Colorado, Austin, and Waller
counties have been discontinued. The tropical storm warning continues
unchanged. Sustained winds, or frequent gusts to around or above
75 mph are expected to occur somewhere within the hurricane warning
area, and winds or frequent gusts exceeding 40 mph expected in the
tropical storm warning area.

Perhaps of greater impact for most of the area, this storm has the
potential to bring widespread and significant heavy rainfall. Rainfall
amounts in excess of 6-12 inches with isolated higher totals are
expected through the end of the day on Tuesday in some locations.
Rather than fall in an even distribution, heavy rainfall will put down
significant totals in relatively short periods, which enhances the
threat of flash flooding. Where the rainfall threat is highest, a
Flash Flood Watch remains in effect. Additionally, 3-5 feet of storm
surge is expected as the system approaches the coastline. This will
result in areas of coastal flooding, particularly during high tide. A
storm surge warning remains in effect along our entire coastline from
Port O'Connor to High Island.



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

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
Coastal Southeast Texas. Remain well guarded against
life-threatening flood waters having possible
devastating 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
Inland Southeast Texas. Remain well guarded against
life-threatening flood waters having possible
limited to extensive impacts.

* SURGE:
Prepare for life-threatening surge having possible significant
impacts along the Southeast 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.

* WIND:
Prepare for dangerous wind having possible significant impacts across
the Southeast Texas Gulf 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 Southeast Texas.

* TORNADOES:
Prepare for a tornado event having possible limited impacts across
the Southeast Texas Coastal Plain. Potential 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.

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

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

* EVACUATIONS:
For those not under evacuation orders, assess
the risk from wind, falling trees, and flooding at your location.

Do not enter evacuated areas until officials
have given the all clear to return.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to stay inside and away from windows. Listen for
updates and be ready in case you lose electrical power. Keep a
battery-powered radio, charged cell phone and flashlight handy.

Do not be a thrill seeker or risk your life for senseless photos or
videos.

If you are prone to flooding or in an area under a storm surge watch
or warning, be prepared for the possibility of a quick and dramatic
rise in water levels.
