Sep. 20 20

 I think the sky looked to be mostly clear with some white, altostratus clouds, at my older sister's house in the Heights area, during the early morning. White altostratus clouds looked to cover most of the sky, during the mid and late morning, at my house in northwest Houston, TX, and at my older sister's house in the Heights area. Low, white to grey stratus clouds started to cover the whole sky, at my house in northwest Houston, TX, Katy, TX, and the Bellaire area, during the early afternoon. Low white to grey stratus clouds continued to cover the whole sky in the Bellaire area and Katy, TX, during the mid-afternoon. Low white to grey stratus clouds covered the whole sky in Katy, TX and at my house in Houston, TX, during the late afternoon and early evening. Low white to grey stratus clouds covered the whole sky, at my house in northwest Houston, TX, during the late evening and night. A light drizzle was falling off and on, on my way from my older sister's house in the Heights area to my house in northwest Houston, TX, during the late morning. Light to moderate rain with some moderately heavy rain started to fall at my house in northwest Houston, TX, during the early afternoon and continued to fall on my way to pick up cats in Katy to take to a foster in the Bellaire area and then back to Katy, TX, and then back to my house, through the rest of the afternoon and evening. The rain looked to have stopped at my house in northwest Houston, TX, sometime during the early or late evening. The wind speeds were mostly calm with some possible 15 to 20 mph wind gusts and maybe some stronger. Especially during the night, at my house in northwest Houston, TX. It felt a little cool throughout the day.

Thoughts:

Well, it looks like Houston, TX is going to be spared a mostly major event with just some minor tropical force winds and some possible although unlikely prolonged flooding. Only some likely flash flooding and hopefully no power outages or much structural damage to any trees, powerlines, or buildings. It has been a crazy hurricane season! I am excited for this to be over soon. The only area that seems to be affected the most is south Houston coastal areas and Galveston/beaches along the coast of southeast Texas. And I think tomorrow is the first day of fall? Or is it the day after? I don't remember. But I am going to miss summer. I really enjoy warm/hot weather over cool and cold.

Area Forecast Discussion
National Weather Service Houston/Galveston TX
722 PM CDT Sun Sep 20 2020



.AVIATION [00Z TAF Issuance]...

Tropical Storm Beta continues to bring MVFR to IFR conditions to the
area. A small lull in the winds is coming to an end as another band
along the coast begins to move inland. Going off what the conditions
went to today with an outer band, conditions will be IFR with areas
of heavier rainfall at times with lowered visibility and ceilings.
With landfall in the southwestern CWA tomorrow afternoon, conditions
are not looking to improve much through the forecast period. Expect
tropical storm force winds along the coastal TAF sites and higher
winds still elsewhere. Ceilings and visibility are expected to
remain at or around the MVFR and IFR category as the system makes
landfall and moves across the southern CWA over the next couple of
days. 35

&&

.SHORT TERM [Through Monday Night]...

Bands of Tropical Storm Beta has started to move through the area.
While most rain has been light to moderate, there has been a few
areas that has had some heavier rainfall. mainly in the southern
counties. Winds have also increased across the area today with gusts
peaking at 38mph so far in galveston. Through the rest of the day,
we can expect conditions to be about the same across the CWA.
Northeasterly winds with higher gusts neat the coastal counties
through the night will be expected. Bands of rain showers will
continue to move into the area from the southeast and produce
showers across the CWA. At times, some of the showers could be heavy
at times and cause localized flooding. Due to the slow movement of
TS Beta, flash, urban, and river flooding is likely.

Tomorrow we can expect an increase in the amount of coverage and
amounts of rainfall across the CWA as TS Beta get closer to
landfall. Current track is still showing TS Beta making landfall
Monday night as a tropical storm. The system will become more
disorganized as it moves inland and start to turn northeastward.
Over night tomorrow, the bands of rain showers and widespread rain
will be at the peak of rainfall totals and coverage. Wind speeds
will be peaking along the coast as well at tropical storm strength
as the system makes landfall, then begins to weaken as the center
moves inland through the night. Mainly the southern counties will be
effected by the tropical storm strength winds and even more so in
the southwestern counties. Tomorrows high will reach mid 70s in the
norther counties after a mid 60s low tonight. Along the coast, highs
will reach mid 80s after mid 70s low. Tomorrow night, will be in the
upper 60s in the northern counties and upper 70s along the coast.
35

.LONG TERM [Tuesday through Saturday]...

Tues/Weds forecasts will be largely dependent on Beta and where it
eventually tracks and weakens. Per current/official thinking, this
system will be lingering in/near the region and this will keep the
potential for heavy rain in place through Tues...perhaps beginning
to decrease Weds. Confidence is low as to which locations will see
the heaviest rains except that it should be over the southern half
of our CWA. QPF forecasts are still indicating rainfall totals for
the event to average from 8 to 12 inches...with isolated totals up
to 20 inches possible.

Even as Beta continues to weakens through the middle to end of the
week, will be keeping scattered rain chances in the grids for this
time period. Models are indicating the development of a weak elong-
ated shear axis stretching along the TX coast and ENE into the mid
MS River Valley in its wake. This instability along with lingering
low-level moisture should be enough to support this activity. Then
looking further ahead...perhaps another cold front late during the
latter part of the upcoming weekend. 41

.MARINE...

Tropical storm conditions will prevail tonight and Monday across
the Middle/Upper Texas coasts as Tropical Storm Beta continues a
slow WNW track towards the area. A brief flare up of convection/
intensity earlier this afternoon did give some cause for concern
but things seemed to have eased off...and TPC is still expecting
Beta to move inland tomorrow as a tropical storm. The prevailing
N/NE winds that have been in place before/during this event will
be shifting to the W then SW across our Gulf waters as Beta slow-
ly moves further inland Tues/Wed. Seas are forecast to be in SCA
range (5-8ft) through at least Weds. A return of mostly light to
moderate offshore winds could be back in place across our marine
waters by late Tues for the offshore waters...dropping off as we
head north towards the bays as Beta further weakens by Weds. 41

SITUATION OVERVIEW
------------------
Although attempting to better organize itself earlier this afternoon,
Tropical Storm Beta continues to battle dry air and wind shear as it
moves west-northwestward towards the middle texas coastline. The current
forecast intensity remains unchanged. Beta remains on track to make
landfall near Matagorda Bay late Monday, then take a turn to
the northeast Tuesday through Thursday. Arrival of tropical storm
force winds is most likely Monday morning, but could arrive as early
as this evening.

We continue to anticipate a prolonged heavy rainfall and coastal
flooding event from Beta with elevated tides already occuring bringing
coastal flooding. Coastal flooding will remain a threat through
midweek with the worst of the storm surge anticipated on Monday and
Tuesday. The first rainbands from Beta have started to move onshore
today, but the heaviest rain will not occur until Monday into
Tuesday. Generally 6 to 12 inches of rain is expected with locally
higher amounts of around 15 inches along the immediate coast.
The combination of storm surge and heavy rainfall along with high
tides will elevate the risk of dangerous flooding along the Barrier
Islands and inner coastal locations through mid-week.

Many local authorities have issued voluntary evacuation orders for
low-lying and flood-prone areas. If you are within an area where an
evacuation warning has been issued, please heed the advice of your
local officials. The storm surge and flash flooding impacts of Beta
will have the potential to be life-threatening.

* SURGE:
Prepare for life-threatening surge having possible significant
impacts across the Barrier Islands and coastal regions from
Matagorda Bay through Galveston Bay. 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 life-threatening rainfall flooding having possible
extensive impacts across portions of Southeast Texas with the
highest rain totals expected along the coast. Potential
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.

Prepare for dangerous rainfall flooding having possible significant
impacts across across the Northern Brazos Valley and up
towards Houston County.

* WIND:
Prepare for dangerous wind having possible significant impacts across
along the immediate coast, especially near the landfall location which
is expected to occur near Matagorda Bay. 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, protect against hazardous wind having possible limited impacts
across most of Southeast Texas.

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

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

For those not under evacuation orders, assess the risk from wind,
falling trees, and flooding at your location. If you decide to move,
relocate to a safer location nearby. If you do not relocate, help
keep roadways open for those under evacuation orders.

If evacuating, leave with a destination in mind and allow extra time
to get there. Take your emergency supplies kit. Gas up your vehicle
ahead of time.

* 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.

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!

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.

...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH TUESDAY EVENING...

The Flash Flood Watch continues for

* Portions of south central Texas and southeast Texas...
  including the following counties...in south central Texas...
  Coastal Jackson and Inland Jackson. In southeast Texas...
  Austin...Brazoria Islands...Chambers...Coastal Brazoria...
  Coastal Galveston...Coastal Harris...Coastal Matagorda...
  Colorado...Fort Bend...Galveston Island and Bolivar
  Peninsula...Inland Brazoria...Inland Galveston...Inland
  Harris...Inland Matagorda...Matagorda Islands...Montgomery...
  Northern Liberty...Southern Liberty...Waller and Wharton.

* Through Tuesday evening

* Prolonged heavy rainfall from Tropical Storm Beta will have the
  potential to produce rainfall totals averaging 6 to 12 inches
  with isolated amounts around 15 inches. The threat of flooding
  along the coast is also increased due to storm surge potentially
  reducing the ability of rainfall to drain. The heaviest rainfall
  will occur Monday into Tuesday.

* This prolonged period of rainfall will have the potential to
  produce life-threatening street and structure flooding.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead
to Flash Flooding. Flash Flooding is a very dangerous situation.
You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.

Do not enter or cross flowing water or water of unknown depth.
You may be risking your life if you do so. Flooding is
responsible for almost 90% of all tropical cyclone-related deaths
in the United States.
