Thank you. Just concerned and have resigned myself to the fact our bay house in Port Alto will not survive.

What an unbelievable disaster the Euro is. If that verifies.. I can't even begin to think what kind of damage that will cause. Curious to see what the ensembles show.

The noon and 1p.m. updates showed the same direction/speed at 335/10mph.

Not sure if that helps or hurt the 6 hour track diff or not.
Latest recon fixes are a little more NW versus NNW which is good news but it still is a little north of the forecast track.
Best news I've heard all day.

Can anyone verify how historically accurate the Euro has performed against the ensembles? This scenario is downright frightening.

Hmm. Would the Euro mean less rain/wind for an area a bit inland such as Sugar Land, since it wouldn't be sitting there as long with us in the dirty side, or would it wind up being about equal or more due to a re-strengthened storm passing closer by (but more in the northwest quadrant)?

I want to take a moment to thank all the pro mets on this forum. I wasn't on this forum for Ike or I might have been more informed. Been following here for a long time now. It is where I come to find out the real scoop. Weatherman on another news channel said this afternoon what ya'll have been saying since early this morning.

Yeah, that's brutal. Harvey strengthens on its re-emergence around Lockport and then track parallel to the coast.

- A Storm Surge Warning and Hurricane Warning are in effect for
Aransas, Calhoun, Kleberg, Nueces, Refugio, San Patricio, and
Victoria

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

Harvey is now a Category 1 hurricane across the west central Gulf
of Mexico. Harvey is expected to continue to strengthen as it moves
toward the Texas coast this afternoon through Friday. Harvey is
expected to reach Category 3 status prior to landfall. Tropical storm
force winds could approach coastal areas in the Coastal Bend as early
as early Friday morning.

Heavy rainfall is expected through much of the area with rainfall
totals of 15 to 20 inches east of Interstate 37 with isolated amounts
around 30 inches possible. Lesser amounts are expected further west
and southwest. These numbers and locations are subject to change
depending on the exact location of landfall along the Texas coast.
Flash flooding is possible with these high rainfall totals. The
heaviest rains are expected to occur Thursday night through Saturday
night and possibly into early next week.

Peak Storm surge inundation is generally expected to be 6 to 10 feet
above ground level from the north entrance of the Padre Island
National Seashore northward to Port O Connor. South of the North Padre
Island National Seashore is generally expected to be 5 to 7 feet above
ground level. Impacts would be felt along the barrier islands and into
the inland bays and waterways. Isolated locations could see slightly
higher inundation.

Tornadoes are possible as rainbands move onshore Thursday night
through Saturday, especially north and east of the center of Harvey.

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

* WIND:
Protect against life-threatening wind having possible devastating
impacts across the Coastal Bend. Potential impacts in
this area include:
- Structural damage to sturdy buildings, some with complete roof
and wall failures. Complete destruction of mobile homes. Damage
greatly accentuated by large airborne projectiles. Locations
may be uninhabitable for weeks or months.
- Numerous large trees snapped or uprooted along with fences and
roadway signs blown over.
- Many roads impassable from large debris, and more within urban
or heavily wooded places. Many bridges, causeways, and access
routes impassable.
- Widespread power and communications outages.

Also, protect against life-threatening wind having possible
significant to extensive impacts across the Brush Country.

* SURGE:
Protect against life-threatening surge having possible devastating
impacts across the Middle Texas Coast and barrier islands. Potential
impacts in this area include:
- Widespread deep inundation, with storm surge flooding greatly
accentuated by powerful battering waves. Structural damage to
buildings, with many washing away. Damage greatly compounded
from considerable floating debris. Locations may be
uninhabitable for an extended period.
- Near-shore escape routes and secondary roads washed out or
severely flooded. Flood control systems and barriers may become
stressed.
- Extreme beach erosion. New shoreline cuts possible.
- Massive damage to marinas, docks, boardwalks, and piers. Numerous
small craft broken away from moorings with many lifted onshore
and stranded.

Elsewhere across SOUTH TEXAS, little to no impact is anticipated.

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across the Coastal Bend, especially east of
Interstate 37. 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.

Protect against dangerous rainfall flooding having possible limited
to significant impacts across the Brush Country.

* TORNADOES:
Protect against a tornado event having possible limited impacts across
South Texas. 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 SOUTH TEXAS, little to no impact is anticipated.

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

* EVACUATIONS:
For those under evacuation orders, leave as soon as practical with a
destination in mind. Gas up your vehicle well ahead of time. Be sure
that you take all essential materials from your emergency supplies kit.
Let others know where you are going and when you intend to arrive.

* OTHER PREPAREDNESS INFORMATION:

The following locations have issued a mandatory evacuation:
- The city of Port Aransas
- Aransas County
- Refugio County
- San Patricio County

CHRISTUS Spohn Health System to close certain locations:
- CLOSED: Robstown, Northside, Westside, Padre Island, Freer,
Beeville, Dr. Hector P. Garcia, and Memorial Quick Care (Reopen
Monday, August 28).
- CLOSED: CHRISTUS Physician Group physician practices.
- ABBREVIATED WORK SCHEDULE: Promptu Clinics will operate a shortened
schedule on Friday, August 25.

Now is the time to bring to completion all preparations to protect
life and property in accordance with your emergency plan.

Outside preparations should be wrapped up as soon as possible before
weather conditions completely deteriorate. Any remaining evacuations
and relocations should be expedited before the onset of tropical
storm force wind.

Closely monitor NOAA Weather radio or other local news outlets for
official storm information. Be ready to adapt to possible changes to
the forecast.

Doing some house cleaning with information that was provided earlier in the day from the WPC regarding Harvey's Flood Potential...

EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
1156 AM EDT THU AUG 24 2017

VALID 12Z SUN AUG 27 2017 - 12Z THU AUG 31 2017

...EXTREMELY HEAVY, IF NOT HISTORICAL, TROPICAL RAINS IS EXPECTED
FOR TX AND LA...


15Z UPDATE
~~~~~~~~~~
THE MEAN UPPER-LEVEL PATTERN WILL BUDGE LITTLE OVER THE NEXT WEEK
WITH A RIDGE OUT WEST AND POSITIVE HEIGHT ANOMALIES EXTENDING FROM
OFF THE WEST COAST THROUGH A LARGE PORTION OF THE WEST INTO
CENTRAL CANADA. MEANWHILE, TWO NEG ANOMALIES, TROUGH OVER THE
NORTHEAST AND HARVEY NEAR SOUTH/SOUTHEAST TX AND WESTERN GULF OF
MEXICO, BECOME ONE AS A TROUGH AXIS ALIGNED FROM THE OH VALLEY TO
THE LOWER MS VALLEY/WESTERN GULF COAST.

ALL EYES THOUGH WILL BE ON HARVEY DURING THE MEDIUM RANGE PERIOD
AND WPC FOLLOWED THE OFFICIAL NHC FORECAST WITH THE TROPICAL
ENTITY THROUGH D5/TUES, A POSITION ALONG THE CENTRAL TX COAST.
AFTER TUES, THE OPERATIONAL GUIDANCE AND ENSEMBLE DATA SHOW
NARROWING SPREAD, AS HARVEY TRAPPED BETWEEN TWO STRONG UPPER
RIDGES FEELS THE INFLUENCE OF A MID TO UPPER TROUGH AND BEGINS TO
TRACK NNE TO NORTHEAST. THE QUESTION IS HOW MUCH INFLUENCE AND HOW
FAR NORTH DOES HARVEY GET. WPC GENERALLY FOLLOWED A BLEND OF THE
00Z GFS/ECMWF/EC MEAN/GEFS MEAN, WHICH DRAWS HARVEY UP TO COASTAL
SERN TX/SWRN LA AND THEN UP INTO EAST CENTRAL LA/WEST CENTRAL MS.
THIS IS THE GENERAL MOTION AND TRACK OF THE GUIDANCE OUT TO NEXT
THURS, THOUGH THE LATEST TREND WITH THE 06Z GFS IS TO WEAKEN
HARVEY AND WASH IS ALONG A CO-RELATED SYNOPTIC FRONT. THIS WILL
NEED TO BE MONITORED ALONG WITH ALL FACETS OF HARVEY AND THE
WESTERLIES.

FOR SENSIBLE WEATHER, THE WPC MEAN MAX TEMP ANOMALY SUGGEST BELOW
AVG HIGHS FROM MID-ATL/SOUTHEAST (FALL-LIKE WEATHER) TO LOWER MS
VALLEY AND TX (HARVEY). ABOVE AVG HIGHS WILL BE VERY LIKELY FROM
THE DESERT SW THROUGH MUCH OF THE WEST, EXCEPT PERHAPS ALONG THE
IMMEDIATE WEST COAST (MARINE LAYER).

THE PRECIPITATION BREAKDOWN LOOKS LIKE THIS, SUN/MON EXTENSIVE
RAINS ACROSS TX WITH HARVEY POSSIBLY EXTENDING INTO LA AND
SCATTERED SHOWERS/STORMS WITH FRONTAL ZONE FROM UPPER MS
VALLEY/WESTERN GREAT LAKES THROUGH OH VALLEY INTO MID MS VALLEY
AND CENTRAL PLAINS WITH SCATTERED SHOWERS/STORMS ACROSS THE FL
PENINSULA AND A BRUSH OF PRECIP ALONG THE SOUTHEAST COAST. THEN
TUES THROUGH THURS, VERY HEAVY RAINS CONTINUE FROM THE MAIN
CORRIDOR OF LA/SOUTHEAST TX UP THE MS RIVER TO THE SOUTHERN OH
RIVER VALLEY AND MORE SCATTERED SHOWERS STORMS WITH THE RETURNING
NORTH SYNOPTIC SCALE FRONT NORTH AND EAST OF HARVEY.

THE BOTTOM LINE IS EXTENSIVE HEAVY TROPICAL RAINFALL ACROSS THE
EASTERN PORTION OF TX INTO LA AND THIS MIGHT BE PUTTING IT MILDLY,
WITH UNFORTUNATELY EXTENSIVE FLOODING POSSIBLE. PLEASE STAY TUNED
TO THE LATEST UPDATES FROM THE NHC ON HARVEY AND RAINFALL INFO
FROM WPC.

My husband heard on the radio just now of mandatory evacuations for all coastal counties. Is this correct? I am in Brazoria county. We are totally hurricane (evacuation) prepared, but I haven't seen anything about Brazoria Co. and wondering if the radio station was exaggerating.
Please advise,
Thanx Yall for all you do!

IMO, If you are packed and ready, I would leave, beat the rush. I'm sure at some point you will be in the mandatory zone so might as well head out now if you have a place to go....that's what I would do, FWIW....best of luck to you!
