Welcome to IWETHEY!

New I saw in passing that someone estimated it will be a cubic kilometer of rain before it's done.
1 km^3 = 2.64E11 gallons = 264 B gallons = 0.264 T gallons.

It's a (veritable) mountain of water, but someone is off by an order of magnitude.

Cheers,
Scott.

Welcome to Rivendell, Mr. Anderson.
New Blimey.
God must really hate Houston, or at least think it needs a hell of a wash.
New Re: God must really hate Houston?
That is the home of the idea that climate change is a Chinese hoax.

New Speaking of dams...
That is a huge amount of water. :-(

In their typically understated way, the Army Corps of Engineers said yesterday:

As of 5 p.m. today, the pool elevation at Addicks Reservoir reached approximately 105 feet, which is up from about 103 feet from a previous measurement; while the pool elevation at Barker Reservoir is approximately 99 feet, which is up a foot from its previous reading. These are both record highs; above the April, 2016 pool levels which reached 102.7 feet and 95.24 feet, respectively.

To date, approximately 30 inches of rain has fallen in the watersheds upstream of Addicks and Barker. Estimates from the National Weather Service on rainfall above the reservoirs from today through the remainder of this tropical event is about 10 inches. This estimate is down from the previous 25 inch estimate from yesterday.

“Based on the range of uncertainty of rainfall rates and totals, overflow of the northern Addicks spillway has potential to occur in the early morning hours tomorrow, Aug. 29, with flows migrating toward Buffalo Bayou along the Beltway 8 corridor and crossing I-10,” said Edmond Russo, Galveston District deputy engineer.

Releases from Addicks and Barker constitute about 20 percent of the total flow of Buffalo Bayou, with the remaining 80 percent attributable to watershed runoff below the dams into the bayou network.

“As of 5 p.m., these discharge rates are approximately 3,800 cfs and 3,500 cfs, respectively, for a combined total of 7,300 cfs,” said Russo. The goal is to reach release rates of 4,000 cfs at both dams for a combined discharge down Buffalo Bayou of about 8,000 cfs.”

We estimate the dams will approach this target combined discharge rate tomorrow. No decisions have been made to increase planned discharge rates above this amount. Dam releases are expected to occur for several months following this storm event.

With rainfall still occurring in downstream reaches of Buffalo Bayou and tributaries, as well as with the discharge of water from Addicks and Barker, the elevation of the bayou is holding fairly steady and may take several days to recede.


Emphasis added.

There were reports on the radio this morning that at least one of the dams was being over-topped (which often means failure is likely), but it's not clear if that's the same as "overflow of the spillway". :-(

8000 cubic feet per second = 0.18 acre feet per second = 15600 acre feet per day.

It's a lot of water, and it's not going away anytime soon.

This is going to be a huge disaster for a very long time.

:-(

Cheers,
Scott.
New He's a record. 49.2 inches Fri - Tues.
(CNN)The toll that Harvey is taking on Texas is staggering.

Already, it has dumped 11 trillion gallons of rain over the state, says Ryan Maue with WeatherBell, a weather analytics company. And by the time Harvey dissipates, the state will have seen 25 trillion gallons of rain, he predicts.

Between midnight Friday and 9:20 a.m. Tuesday, 49.20 inches of rain fell in Texas -- a record for continental US from a landfalling tropical cyclone, the National Weather Service said.

"The word catastrophic does not appropriately describe what we're facing," said Rep. Sheila Jackson Lee, who represents much of Houston. "We just don't know when it's going to end."

It's mourning in America again.
New That's usually the *annual* rainfall for Houston!
In the Charlotte area (like Indianapolis) the annual rainfall is 42 inches.
