Sep. 21 20

 Low, white and grey stratus clouds covered the whole sky, at my house in northwest Houston, TX and where I work in the Heights, during the morning, afternoon, evening, and night. The wind speeds were calm with some strong 20 + mph gusts. Maybe even some 30 mph. It felt a little cool throughout the day. A few moderate to moderately heavy showers passed over my house in northwest Houston, TX, during the early morning, before sunrise. Steady light to moderate rain started to fall while I was at work in the Heights sometime during the mid-morning and stopped sometime during the late morning. Moderate to moderately heavy to sometimes heavy rain started to fall, while I was at work in the Heights area, during the mid-afternoon. The moderate to moderately heavy and heavy rain continued on through the late afternoon, where I work in the Heights area. Light on and off drizzle followed me from where I work in the Heights area to my house in northwest Houston, TX, during the early evening. More on and off light to moderate and moderately heavy rain fell at my house in northwest Houston, TX, during the early night. I heard some low rumbles of thunder around 10 PM, at my house in northwest Houston, TX, before the rain stopped sometime during 10 PM. More on and off light to moderate rain still seemed to be falling past 10 PM. Did not hear any more rumbles of thunder

Thoughts: Well it looks like Beta may be more of a rain threat than previously thought. Southwest Houston, TX is getting pounded with some training moderately heavy to heavy rain. Lots of flash flood warnings were issued for the Houston, TX area, during the evening and early night. Houston, TX will see just how much training they will get tomorrow and Wednesday. Hoping that most of the rain stays away from Houston and I am able to go into work tomorrow. 

Although Beta is not going to be any kind of a wind threat. The Hurricane National Center even expired the Tropical Storm warning for the Houston, TX area, or at least most of the Harris County area. Petsmart did make the rescue that I volunteer for in Katy, TX move out all of the cats in their adoptions centers out of precaution and safety.

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

Tropical Storm Beta will be making landfall within the next few hours
near Matagorda Bay. It will then slowly move to the northeast through
midweek. Bands of heavy rain will continue to train across portions of
Southeast Texas through the day tomorrow, with the rain threat 
not ending
until Wednesday when Beta is out of the area. The heavy rain will cause
street flooding and for creeks and bayous to swell past their banks.
Within these rainbands, 4 to 7 inches of rain have already fallen with
additional rain expected. Flooding concerns along the coast will be
compounded with elevated tides due to the onshore winds 
persisting overnight.
Surge will become less of an issue during the day on Tuesday, 
but concerns
for coastal flooding will remain through midweek.

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

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
Southeast Texas with heavy rainbands moving through Galveston, Harris
counties, and areas around Matagorda Bay. Remain well guarded against
life-threatening flood waters having additional extensive impacts.
If realized, these impacts include:
    - Major rainfall flooding may prompt many evacuations and rescues.
    - Rivers and tributaries may rapidly overflow their banks in
      multiple places. Small streams, creeks, canals, and ditches may
      become dangerous rivers. Flood control systems and barriers may
      become stressed.
    - Flood waters can enter many structures within multiple
      communities, some structures becoming uninhabitable or washed
      away. Many places where flood waters may cover escape routes.
      Streets and parking lots become rivers of moving water with
      underpasses submerged. Driving conditions become dangerous.
      Many road and bridge closures with some weakened or washed out.

Potential impacts from the flooding rain are still unfolding across
north of Interstate 10. Remain well guarded against dangerous
flood waters having possible limited to
significant impacts.

* SURGE:
Potential impacts from the main surge event are now unfolding across
the Barrier Islands and coastal regions from Matagorda Bay through
Galveston Bay. Remain well away from life-threatening surge having
additional significant impacts. If realized, these impacts 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:
Potential impacts from the main wind event are now unfolding across
the immediate coast, especially near the landfall location which
is expected to occur near Matagorda Bay. Remain well sheltered from
hazardous wind having possible limited impacts. If realized, these
impacts 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.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across Southeast
Texas. Remain well braced against a tornado event having possible
limited impacts. If realized, these 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.

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

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

* OTHER PREPAREDNESS INFORMATION:

During the peak of the storm be ready to move quickly. Keep your
shoes on and rain gear handy. Boots and athletic shoes offer the best
foot protection if you become unexpectedly exposed to the weather.

Keep your cell phone charged and in power-saving mode. If you lose
power, use it sparingly and mainly for personal emergencies and
check-ins.

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.

If a tornado warning is issued for your area, quickly move to the
safest place within your shelter. Protect your head and body.

The next local statement will be issued by the National Weather
Service in Houston/Galveston TX around 4 AM CDT, or sooner if
conditions warrant.

.AVIATION [00Z TAF Issuance]...

Tropical Storm Beta continues to bring MVFR to IFR conditions to the
area. Gusty northeasterly to easterly winds as bands stream across
the area. IFR ceilings around 700ft are expected through the night
with IFR visibility around 1-2sm in rain. Tomorrow ceilings around
500ft with temporary lower ceilings are expected to form as the
system moves across the coastline. 35

&&


.SHORT TERM [Through Wednesday Night]...

Tropical Storm Beta is still slowly moving its way to the SETX
coast. Sitting just outside the Matagorda Bay area, landfall is
expected tonight still. Rain fall is still expected to continue
through the evening and into the night. Winds are decreasing in
speed and expected to decrease under tropical storm force tomorrow
night as the system moves along the coastline near the
Matagorda/Angleton Co area. Rain bands will become more wide spread
across the SETX area as the storm loses strength and organization
throughout tonight and the day tomorrow. Tomorrow night and through
Wednesday morning, the system is expected to be moving out of the
area. Chances will be decreasing across the CWA through Thursday
early morning. Winds are going to be on the decline tonight with
winds at or under tropical storm force along the southern coastal
counties. By wednesday night and into Thursday early morning, winds
will have decreased to northerly around 10mph. 35


.LONG TERM [Thursday through Monday]...

While the remnants of Beta are expected to be well E/NE of the CWA
by Thurs, some isolated/widely scattered rain chances could linger
over parts of SE TX through the end of the week. A broad mid/upper
level trof axis is progged to develop across the state (stretching
from the lower Rio Grande Valley E/NE towards SE TX) could provide
enough instability to produce some activity across this area. How-
ever, moisture levels should be rather limited in the wake of Beta
and will keep our "best" POPs over the eastern CWA. These low POPs
could persist into Fri/Sat as light onshore winds resume...and may
be helped along by the seabreeze.

While previous model runs were more aggressive with the idea of a
cold front moving down into the region on Sun, 12Z runs appear to
be backing off a little bit. A rather amplified upper ridge build-
ing in over the western U.S. seems to be shunting the bulk of the
colder air more east of the region initially(Sun) but a deepening
upper low tracking over the Northern Plains could be advantageous
in driving a second stronger cold front into SE TX by next Tues.
Time will tell. 41


.MARINE...

With Tropical Storm Beta continuing to slowly make its way towards
the Central TX coast, conditions will remain poor across our bays/
coastal waters tonight into tomorrow morning. The latest TPC track
has Beta moving along/just off the Upper TX coast through tomorrow
as it weakens to a remnant low. The southerly flow on the backside
of this storm system (mainly our offshore waters tonight/tomorrow)
will be shifting to the N/NW by Weds as it moves northeasterly out
of the region. Tropical storm conditions are expected to "improve"
to Small Craft Advisory conditions early late Tue night/early Weds
morning...with most flags likely gone by Weds night. Thereafter, a
generally light/moderate offshore flow should prevail for the rest
of the week. Light onshore winds are set to resume by late Fri and
Sat. A weak cold front is possible Sun, but models are now hinting
that a second stronger front could push off the coast by next Tues.
