Oct. 8 20

 Low white, grey, and blue stratus clouds looked to cover most of the sky, at my house in northwest Houston, TX and where I work in the heights area, during the early morning. Low white, grey, and blue stratus clouds looked to cover most of the sky, where I work in the Heights area, during the mid-morning. Low white and grey stratus clouds started to cover the whole sky, where I work in the heights area, during the late morning. Low white and grey stratus clouds covered the whole sky, where I work in the heights area, during the afternoon and early evening. Low white and grey stratus clouds looked to cover the whole sky, where I work in the heights area and in northwest Houston, TX, during the late evening. Low white and grey stratus clouds looked to cover the whole sky in northwest Houston, TX, during the night. The wind speeds were light with some occasional moderate to possibly moderately strong gusts. A moderate to light shower passed over where I work in the heights area, during 11 am and another one at around 2 pm. I only saw on and off sprinkles through the rest of the day, after the moderate shower at 2 pm. The day was warm/maybe a little cool during the early morning.

Thoughts: Had a heartbreaking scene at work today with an evacuee from Louisana trying to find a place to board their pets. I really feel bad for the people in Lousiana going through another hurricane. Although I am glad that it is not coming towards us.

.AVIATION...

Bands of showers associated with Hurricane Delta will continue to move
onshore and across SE TX tonight and tomorrow. Could see some isolated
thunderstorms too. Look for lowered ceilings and visibilities in and
around the convection. Increasing NE to N winds and wind gusts (much
stronger at GLS) can be expected during the day tomorrow as Delta heads
northward and makes landfall around sunset along the SW Louisiana coast.

..EXPANSION OF THE TROPICAL STORM WARNING DOWN THE COAST TO
SARGENT...

..UPGRADING THE 20-60NM WATERS EAST OF FREEPORT TO HURRICANE
WARNING...

SHORT TERM [Today through through Saturday Night]...

Rain bands associated with Hurricane Delta have been and will be
continuing to move onshore through SE TX tonight and tomorrow.
However, the rather dry airmass that has been in place over the
area has been making it hard for these bands to produce
significant rain totals at the surface so far today, especially
for our northern CWA. But as we continue to see these lines move
inland with Delta`s approach toward the northern Gulf coast, the
air mass should moisten with time. Rain chances will remain high
tomorrow with the gradient of the higher POP numbers over the
eastern/coastal CWA to much lower to our west. This system is
forecast to move at a fairly rapid pace after it moves inland, so
rain chances will be dropping off quickly tomorrow evening/
night. As for winds, we are likely to see strong gusty winds pick
up tonight/early tomorrow morning for portions of our coastal
counties/beaches. Locations from San Luis Pass east to High
Island along with inland sites from Freeport to Winnie could start
seeing NE gusts at/near 30-35 mph overnight then perhaps close to
40mph tomorrow morning and afternoon. High temperatures should be
a bit cooler tomorrow afternoon given the increased clouds/rain.
41

LONG TERM [Sunday Through Thursday]...
Sunday morning the weakening remains of Delta should be over
northern Mississippi moving quickly away with warm drying
southwesterly flow in place over SETX. Temperatures should climb
into the mid to upper 90s in the northwest and will be right near
the record high at College Station of 96 degrees in 1931 and
forecasting 96 as of this package and can`t rule out 97 or 98 on
the high end of the possibilities. Houston IAH 94 forecast would
also tie the record set in 1962. Upper ridging over Central/East
Texas slides eastward through the day and night into LA/Gulf
Monday afternoon which allows the next cold front to drop
southward into the northern counties late Monday afternoon or more
likely Monday evening after another much above normal day with
lighter southerly flow. Pooled deep tropical moisture trailing
back into the Gulf from Delta to the Bay of Campeche. The cold
front gets a reinforcing push southward early Tuesday and into the
Gulf but only barely. Brief increase in winds with the push but
relatively short lived then winds back to east as front becomes
stationary Tuesday evening. High pressure slides east and
southerly flow resumes Wednesday into Thursday morning. Increasing
cloudiness during this period as moisture Pacific flow aloft
sweeps in from Mexico bringing cirrus to the region. Tuesday and
Wednesday temperatures are back to seasonal levels. Slight chance
of showers or isolated thunderstorms with the frontal passage
Tuesday.

MARINE...
Tropical storm conditions developing after midnight this evening
and worsening to Hurricane conditions for the southeastern most
waters. This track for Delta will bring very strong sustained
winds and high gusts in excess of hurricane force there with
ponderously large seas of 16 to 20 feet building to 22-27 Friday
around sunrise through 1 pm then diminish quickly. Rough bay
waters with sustained northerly winds of 30 to 40 knots and
higher gusts Friday then NW and dropping off to around 15 knots
after 1 am Saturday. Strong currents in the ship channel will
make navigation a challenge on top of the strong winds and
mariners should avoid these conditions if possible.

35/Luchs

TROPICAL...
Hurricane Delta holding around 115 mph Cat 3 and Hurricane
Hunters first pass at 2023z showed estimated surface pressure down
to 959mb. The strongest winds were showing up in the band of
deeper convection the west and southwest side of the system and
this morning shot of dry air was wrapping around and oddly on the
east side of the hurricane. Hurricane guidance still tightly
packed on a track toward SW LA but with enough wind to warrant
hoisting a Hurricane warning for the 20-60nm waters east of
Freeport where strongest winds should occur for our area. The
system starts to really feel the shear and drier air Friday and
should weaken Friday afternoon as it gets into cooler waters
before landfall. Across the surrounding areas of Galveston Bay
expect the strongest winds to arrive in the region Friday 9 am
through 8 pm and be falling off quickly in the 6-9 pm window. Tide
levels will be a big concern for the Sargent area eastward up
into Galveston Bay and Bolivar. This initial northeast winds will
raise tide levels quickly from the 1-1.5 currently astronomical
tide levels to 3-5 feet above MLLW. Coastal Flood warning/advisory
remains in effect for this and expect some impacts such as
flooding onto Highway 87. Large swell will bring very rough
conditions to the beach areas and dangerous rip currents with
extensive run-up to and wave action on the Gulf facing beaches. As
it moves inland the strong northerly winds will likely push water
out of the bay into the back side of Bolivar and Galveston.
Conditions improving very quickly with low tide cycle and
relaxation of winds after 9 pm Friday.

**DELTA STRENGTHENS A LITTLE MORE**


NEW INFORMATION
---------------

* CHANGES TO WATCHES AND WARNINGS:
    - None

* CURRENT WATCHES AND WARNINGS:
    - A Tropical Storm Warning is in effect for Brazoria Islands,
      Chambers, Coastal Brazoria, Coastal Galveston, Coastal Harris,
      Galveston Island and Bolivar Peninsula, Inland Galveston, and
      Southern Liberty

* STORM INFORMATION:
    - About 270 miles south of High Island TX
    - 25.7N 93.6W
    - Storm Intensity 120 mph
    - Movement North-northwest or 340 degrees at 12 mph

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

Hurricane Delta has continued to strengthen this evening as it pushes
further northwestward towards the Central Gulf Coast. The system
should maintain its status as a Category 3 Major Hurricane overnight
before a combination of cooler waters and an increase in shear are
expected to cause it to weaken modestly before landfall. This
will also cause the wind field to expand, which has prompted the
issuance of a tropical storm warning along the SE Texas coast.
Furthermore, a hurricane warning remains in effect for the Gulf waters
from 20 to 60 NM out from High Island to Freeport. This is primarily
for the waters closer to 60 NM out from High Island, which may be
clipped by the core of the expanding storm on Friday.

Due to the close approach of this storm, we will have to watch it
carefully as it passes. T
hose in the watch area should complete preparations
for the impacts of a tropical storm. Even those near 
the watch area will be well
served to keep an eye on the latest information from the NHC and our
office as the storm makes its crossing of the Gulf 
of Mexico in order to stay
ahead of any unanticipated changes.

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

* WIND:
Protect against dangerous wind having possible significant impacts
across across the eastern Galveston Bay area. 
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 across the western Galveston Bay area, and along the 
Gulf coast to
Sargent.

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

* SURGE:
Protect against locally hazardous surge having possible limited
impacts across Galveston Bay and Gulf-facing coasts from High
Island to Sargent. Potential impacts in this area include:
    - Localized inundation with storm surge flooding mainly along
      immediate shorelines and in low-lying spots, or in areas
      farther inland near where higher surge waters move ashore.
    - Sections of near-shore roads and parking lots become overspread
      with surge water. Driving conditions dangerous in places where
      surge water covers the road.
    - Moderate beach erosion. Heavy surf also breaching dunes, mainly
      in usually vulnerable locations. Strong rip currents.
    - Minor to locally moderate damage to marinas, docks, boardwalks,
      and piers. A few small craft broken away from moorings.

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

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across the eastern Galveston Bay 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.

Protect against locally hazardous rainfall flooding having possible
limited impacts across the western Galveston Bay area.

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

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

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

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.

If you are a visitor, be sure to know the name of the city or town in
which you are staying and the name of the county or parish in which
it resides. Listen for these locations in local news updates. Pay
attention for instructions from local authorities.

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.
