What I was suggesting is that for many decades developers have built as they wished, the city didn't care and as drainage issues arose they were not address to a reasonable level.

Houston drainage grid 'so obsolete it's just unbelievable
By SETH BORENSTEIN AND FRANK BAJAK, ASSOCIATED PRESS HOUSTON — Aug 29, 2017, 7:25 PM ET
...
"Houston is the most flood-prone city in the United States," said Rice University environmental engineering professor Phil Bedient. "No one is even a close second — not even New Orleans, because at least they have pumps there."

The entire system is designed to clear out only 12 to 13 inches of rain per 24-hour period, said Jim Blackburn, an environmental law professor at Rice University: "That's so obsolete it's just unbelievable."

Also, Houston's Harris County has the loosest, least-regulated drainage policy and system in the entire country, Bedient said.

Here's how the system is supposed to work: The county that encompasses Houston has 2,500 miles of bayous and channels and more than 300 storm-water holding basins, which are designed to fill up during intense downpours and drain slowly as high waters recede.

Water is supposed to flow west to east through bayous, which are tidal creeks that often have concrete improvements to make water flow and are connected to the Galveston Bay.

When big rains come, officials also activate two normally dry reservoirs, closing the floodgates to collect the water and keep it from overwhelming the downtown area.

But the main bayou through downtown Houston, Buffalo Bayou, "is pretty much still a dirt mud channel like you would have seen 100 years ago, just a little cleaned out," said U.S. Geological Survey hydrologist Jeff East, who is based in Houston.

And because the coastal plain is so flat, only sloping about a foot per mile, the water doesn't flow out of the bayous fast, Bedient said.

Also, some of the bayous, such as Brays, can only handle 10-year storms, he said. Harris County didn't leave enough right-of-way space to expand its bayous, Bedient said. And widening projects have been slow and inadequate.

Current Scenario:
Possible gas shortages on the East coast with a Hurricane 5 possibly barreling in.

"Major Hurricane Irma now ... I'd be surprised if storm didn't become Cat 5 during next 5-7 days. Many EPS ensembles are very intense."

By clicking on that guys twitter page, there are several models showing the predicted path.

When I analyzed the Harvey model, the storm appears to take an average of the models, meaning, somewhere in between the majority of the models (mean value).

The majority show landfall on Florida, Carolina, or something fun like it barreling along the coast.

Hype Train. To believe or not to believe.

Michael Ventrice Tweets:
"These are the highest windspeed forecasts I've ever seen in my 10 yrs of Atlantic hurricane forecasting. #Irma is another retiree candidate."

"Wow, a number of ECMWF EPS members show a maximum-sustained windspeed of 180+mph for #Irma, rivaling Hurricane #Allen (1980) for record wind"
