Tropical Storm Harvey Advisory Number 28
NWS National Hurricane Center Miami FL AL092017
400 AM CDT Sun Aug 27 2017

...HARVEY CAUSING CATASTROPHIC FLOODING IN SOUTHEASTERN TEXAS...


SUMMARY OF 400 AM CDT...0900 UTC...INFORMATION
----------------------------------------------
LOCATION...29.2N 97.7W
ABOUT 50 MI...80 KM ESE OF SAN ANTONIO TEXAS
ABOUT 95 MI...155 KM NW OF PORT OCONNOR TEXAS
MAXIMUM SUSTAINED WINDS...45 MPH...75 KM/H
PRESENT MOVEMENT...SSW OR 200 DEGREES AT 1 MPH...2 KM/H
MINIMUM CENTRAL PRESSURE...998 MB...29.47 INCHES


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

The Tropical Storm Warning south of Port O'Connor has been
discontinued.

The Storm Surge Warning south of Port O'Connor has also been
discontinued.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Storm Surge Warning is in effect for...
* Port O'Connor to Sargent Texas

A Tropical Storm Warning is in effect for...
* Port O'Connor to Sargent 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.

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 400 AM CDT (0900 UTC), the center of Tropical Storm Harvey was
located near latitude 29.2 North, longitude 97.7 West. Harvey is
moving toward the south-southwest near 1 mph (2 km/h), and a slow
southeastward to east-southeastward motion is expected over the
next couple of days. On the forecast track, the center will remain
inland or move very near the coast of southeastern Texas through
Monday.

Maximum sustained winds are near 45 mph (75 km/h) with higher gusts.
Some weakening is forecast during the next 48 hours, and Harvey is
likely to become a tropical depression by tonight.

Tropical-storm-force winds extend outward up to 60 miles (95 km)
from the center. An NOS site near the entrance to Matagorda Bay
recently reported sustained winds of 40 mph (65 km/h) with a gust
to 53 mph (85 km/h).

The estimated minimum central pressure is 998 mb (29.47 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: Harvey is expected to produce additional rain
accumulations of 15 to 25 inches over the middle and upper Texas
coast through Thursday. Isolated storm totals may reach around
40 inches in this area. Rainfall of this magnitude will cause
catastrophic and life-threatening flooding. Elsewhere during the
same time period, Harvey is expected to produce total rain
accumulations of 5 to 15 inches farther south toward the lower Texas
coast, farther west toward the the Texas Hill Country, and farther
east through southwest and central Louisiana. 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...1 to 3 ft
Port O'Connor to Sargent...2 to 4 ft
Sargent to High Island including Galveston Bay...1 to 3 ft
High Island to Morgan City...1 to 2 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: Tropical storm conditions are occurring in an area near the
center and over portions of the tropical storm warning area along
the coast. These conditions are likely to persist through this
morning.

SURF: Swells generated by Harvey affecting the coasts of Texas
and Louisiana should subside through this morning. These swells
are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.

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

Just a thought- is there a way the TWBot posts could be put into a separate thread from the discussion about the storm from real people?

It's a lot of repetitive text to scroll past and makes this thread really cumbersome to read.

What's happening in Houston and southeast Texas is truly horrible. I'm afraid we may be well surpassing Katrina on the scale of this disaster. Houston is something like the fourth largest US city, and it is at its knees with historic flooding.

I hope we don't have the same death toll as Katrina. Harvey may end up being the costliest natural disaster in US history. Next week, LSU and BYU were supposed to play in Houston at the Texans stadium. That game might be in jeopardy. They could move the game to Baton Rouge.

Take a moment right now and pray for Houston, TX. They're experiencing deadly flooding with over 2 feet of rain in 24 hours. They're saying, when this is over, some places in Houston will experience 60 inches of rain. They are being told to go straight to their roof, if they call 911, stay on line till they're able to get to them, if 911 can't be reached to call the US Coast, the Coast Guard has had 300 search and rescue calls already.
A good bit of their population are Katrina refugees.
Evacuating such a large city that wasn't in the direct path was not feasible.
Again, take a second to pray for Houston, TX residents, first responders, hospitals and shelters!!

Wanted to take moment to explain some changes that are coming. With Harvey on shore, we are going to stop the TWBot updates for Harvey. As you may have noticed the NHC is including a lot more information in these updates and they are quite long. I'm working on an update on the backend that will just extract the key information of the advisory updates such as location, speed, direction, pressure and wind speed. Once we have that back online I'll turn the updates back on.

Dams have reached 100 year flood stage for 2 reservoirs. Army corp of engineers are releasing water at 2am from main reservoir to keep from failing, but it's going to put about 200 homes under 3-5' of water near downtown.

Just got off the phone with some friends from Houston. Major issues everywhere and to quote one friend who is a doctor at a Houston area hospital. I should mention she has been on duty for almost 48 hours and just got some down time thanks to staff from another hospital in Texas coming over to help out.

"The Mayor is an idiot because he could have easily called for an evacuation 72 hours ahead of the arrival of the storm that we knew was going to take 3-4 days to clear, but instead he was worried about people having to wait 12 hours on the interstate. Complete moron."

The area still hasn't recovered from the memories of the Rita evacuation, which was a disaster in and of itself. I'm not sure what the right answer was here as there was less time to prepare.

Harvey is just about back over water. Now it'll be interesting to see how much, if at all, it's above to strengthen before making landfall again.
