August 2017: Looking Back at Harvey 5 Year Later

[relic57]

Not a fan of that Northward movement.

I am seeing a northward movement too. I wonder if it is a wobble.

Okay, so I am not the only one...sure looks to me to be moving in a more Northerly direction.

[Rip76]

Lots of lightning with these outer bands.

[Waded]

I'm worried about this Jeff guy that has been live streaming from Rockport. He was last seen sheltering next to a Walmart. Those are lightly constructed buildings. Big box stores have a poor record in storms. Unless he broke into the auto bay and is sheltering below ground in the oil change pit I fear his chose his shelter poorly.

Looks like a wobble to me.

Pretty significant velocity return near Alvin / Rosharon indicating a tornado.

Euro and GFS starting to go back and disagreeing with each other on track wise. Euro is staying consistent in it moving back out over the Gulf and making another landfall south of Bay City and slowly moving N/NE.

For those who didn't see the GFS, it has it moving back south near Rockport, flirting with the coast before ejecting north into central TX. Tiring days ahead...

[Belmer]

HRRR has been very concerning (and consistent with several runs now) showing Houston and eastward getting 10+ inches of rain during the next 12+ hours. Showing eventually one of the rainbands will develop and just sit over our area like what is happening over Brazoria Co.

[tgal]

First let me thank everyone that has been tireless giving of themselves during this event. As always it is appreciated. Also, could someone let us know if Jeff is Ok? A simple yes or no is fine. I won't pry for information I am simply worried because I know he was in Rockport and the backside of the storm was coming in

Thanks again for everything

So here in Sugar Land I've been through 3 Tornado Warnings which were well warranted based on the swirling wind that we experienced. I heard about the damage in Sienna, but the big take from this was the torrential rainfall that seemed not to want to stop due to training. Flooding is a huge concern!!! Places that don't normally flood are even in play with these type of rainfall rates.

Catastrophic Flood Event underway. Jeff has reported that Rockport High School was destroyed. Day 1 and 2 Excessive Rainfall are High Risk for the next 48 hours as Harvey meanders over portions of S Central Texas.

[relic57]

Power out here in Atascocita (Eagle Springs)

[srainhoutx]

4:00 AM Saturday Update from Jeff:

Powerful hurricane Harvey pounding the coastal bend and SC TX with hurricane force winds

Event will slowly transition into a very dangerous and life threatening flood event

A devastating hurricane landfall has occurred with many reports of structural damage and collapsed homes/buildings. Numerous towns have 911 calls with trapped persons inside collapsed buildings including: Portland, Rockport, Refugio, and Port Aransas

Many observation sites have either failed or lost power so we are getting very few winds reading any more. The surface pressure has risen from 938mb at landfall to 956mb currently and sustained winds have decreased from 130 to 110. Hurricane force winds…mainly in strong gust will continue to affect the Matagorda Bay region and SC TX/brush country through late morning.

Damaging storm surge continues to fill NW Matagorda Bay with Port Lavaca currently reporting a surge of 7.47 ft (appears near peak) and Seadrift on the eastern part of San Antonio Bay reporting 5.40 ft. Given the position of Harvey, continued strong (near hurricane force) winds will continue to push water into Matagorda Bay and pile it into the upper portions of Lavaca Bay around Port Lavaca and Point Comfort

Rainfall:
Overall event will be transitioning to a flash flood/flood event today and continue for the next several days. Heavy core rainfall continues near the center with rainfall totals already nearing 15 inches. Significant banding continues to develop and train NW across SE TX especially over Fort Bend and Brazoria Counties where widespread rainfall of 6-8 inches has occurred overnight with isolated totals of up to nearly 10 inches. A LCRA gage at Bay City has recorded 8.92 inches in the last 24 hours.

Recent discussion from WPC highlights the I-45 corridor through the morning hours for the formation of very heavy rainfall and this appears possible given recent radar trends showing rapid development of numerous training cells over the NW Gulf and the slow approach of an impressive feeder band currently moving into Fort Bend and Brazoria Counties. Hourly rainfall rates have been increasing on radar into the 2.0-2.5 inch range. Trends on radar will need to be monitored closely over the next several hours

Tornadoes:
There have been numerous tornado warnings overnight with cells moving across Brazoria and Fort Bend Counties. These cells are racing NW and producing short lived tornadoes. One touch down in Missouri City has produced damage to homes and minor injuries. Additionally, the stronger cells in the feeder bands are resulting in the transport of higher momentum to the surface and wind gusts of 45-55mph which is causing some power outages.

Tornado Watch remain in effect until 100 PM this afternoon. That may need to be re issued. Seeing numerous reports of quick spin up Tornadoes across our Metro Houston Region as Harvey's feeder bands expand outward from its center. Current location of now CAT 1 Harvey is about 25 miles SW of Victoria.

[srainhoutx]

Update from Jeff:

Flash Flood Warning for south and central Harris County until 845am

Strong feeder band is approaching from the SSW and converging with numerous incoming cells moving inland off the Gulf of Mexico. A quick 2-3 inches of rainfall will be possible over the SW half of Harris County over the next 1-1.5 hours.

Street flooding is the main concern at this time, but rises on creeks and bayous will commence with these heavy rains.

Mesoscale Discussion 1572
NWS Storm Prediction Center Norman OK
0649 AM CDT Sat Aug 26 2017

Areas affected...the Galveston Bay/Greater Houston area

Concerning...Tornado Watch 467...

Valid 261149Z - 261345Z

The severe weather threat for Tornado Watch 467 continues.

SUMMARY...The intermittent but long-duration risk for short-lived
supercell tornadoes will maximize in the Galveston Bay/Greater
Houston area this morning.

DISCUSSION...The latest subjective surface streamline analysis
implies low-level convergence is focused across the Galveston Bay
vicinity. Surface observations also show temperatures in the lower
80s degrees F from Brazoria County to Houston Hobby and
east-northeast to Beaumont. Dewpoints are ranging from the upper
70s to around 80 at the coast. As a result, buoyancy is maximized
in the discussion area compared to areas farther inland and closer
to the center of Harvey. Time trends in the KHGX VAD suggest a
decrease in hodograph size has occurred during the past few hours
with 0-1 km SRH less than 50 m2/s2 according to observed storm
motions. Nonetheless, the moist-tropical airmass will support
intermittent low-level rotation with the strongest updrafts embedded
within convective bands and clusters for the next several hours.

WATCHES AND WARNINGS
--------------------
CHANGES WITH THIS ADVISORY:

None.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Storm Surge Warning is in effect for...
* Baffin Bay to High Island Texas

A Hurricane Warning is in effect for...
* Baffin Bay to Port O'Connor Texas

A Tropical Storm Warning is in effect for...
* North of Port O'Connor to High Island Texas

A Storm Surge Warning means there is a danger of life-threatening
inundation from rising water moving inland from the coastline in the
indicated locations. For a depiction of areas at risk, please see
the National Weather Service Storm Surge Watch/Warning Graphic,
available at hurricanes.gov. This is a life-threatening situation.

A Hurricane Warning means that hurricane conditions are expected
somewhere within the warning area.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning.

Interests in southwestern Louisiana should continue to monitor the
progress of this system.

For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.


DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 700 AM CDT (1200 UTC), the eye of Hurricane Harvey was located by
NOAA Doppler radar near latitude 28.7 North, longitude 97.2 West.
Harvey is moving toward the north-northwest near 6 mph (9 km/h).
Harvey is expected to slow down through the day and meander over
southeastern Texas through the middle of next week.

Doppler radar data indicate that maximum sustained winds have
decreased to near 80 mph (130 km/h) with higher gusts. These winds
are confined to a small area near the eye of the hurricane.
Additional weakening is forecast, and Harvey is likely to become a
tropical storm later today.

Hurricane-force winds extend outward up to 35 miles (55 km) from
the center, and tropical-storm-force winds extend outward up to 140
miles (220 km).

The estimated minimum central pressure is 975 mb (28.79 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: Harvey is expected to produce total rain accumulations of
15 to 30 inches and isolated maximum amounts of 40 inches over the
middle and upper Texas coast through next Wednesday. During the same
time period Harvey is expected to produce total rain accumulations
of 5 to 15 inches in far south Texas, the Texas Hill Country
and southwest and central Louisiana. Rainfall of this magnitude
will cause catastrophic and life-threatening flooding. A list of
rainfall observations compiled by the NOAA Weather Prediction Center
can be found at: www.wpc.ncep.noaa.gov/discussions/nfdscc1.html

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water is
expected to reach the following heights above ground if the peak
surge occurs at the time of high tide...

Port Aransas to Port O'Connor...6 to 12 ft
Port O'Connor to Sargent...6 to 9 ft
Sargent to Jamaica Beach...4 to 6 ft
Baffin Bay to Port Aransas...3 to 6 ft
Jamaica Beach to High Island...2 to 4 ft
Mouth of the Rio Grande to Port Mansfield...1 to 3 ft
High Island to Morgan City...1 to 3 ft

The deepest water will occur along the immediate coast near the
area of onshore winds, where the surge will be accompanied by large
and destructive waves. Surge-related flooding depends on the
relative timing of the surge and the tidal cycle, and can vary
greatly over short distances. For information specific to your
area, please see products issued by your local National Weather
Service forecast office.

WIND: Hurricane conditions are occuring inland from the coast
within Harvey's eyewall, and hurricane-force winds, especially in
gusts, are still possible near the middle Texas coast for the next
several hours. Tropical storm conditions are occurring in other
portions of the hurricane and tropical storm warning areas.
Tropical storm conditions are likely to persist along portions of
the coast through at least Sunday.

SURF: Swells generated by Harvey are affecting the Texas,
Louisiana, and northeast Mexico coasts. These swells are likely to
cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.

TORNADOES: Tornadoes are possible today and tonight near the middle
and upper Texas coast into far southwest Louisiana.
