As of early afternoon on Saturday Harvey was about to be downgraded to a strong tropical storm after slamming into the Texas coast as a Category 4 monster hurricane packing 130 mph sustained winds. Residents along the coast are just now starting to assess the initial damage from this first major blow. However, the big rain event that is Harvey is just now getting started.
(Harvey’s rains expand over Eastern Texas at 245 PM EST. Image source: National Weather Service.)
According to the National Hurricane Center, the storm’s forward speed has now slowed down to about 2 miles per hour in a north-bound direction. Meanwhile, its shield of encircling rains is expanding to cover most of eastern Texas. These rains are very intense — producing accumulations of more than 1 inch per hour in many locations. And with Harvey stalling out, such heavy rains are expected to persist over basically the same region and at a similar high intensity for at least the next four days. After that time, Harvey is expected to persist and rains of lighter, but still flood-producing force, may continue to fall over parts of Texas for up to five more days.
(Harvey has already dumped nearly 15 inches of rain on some locations. Despite this fact, NOAA is still predicting more than 20 inches of additional rain. Some models are indicating that final totals could range from 40-60 inches in some locations after a 6-10 day rain event. Image source: NOAA.)
It’s worth noting that though up to 15 inches of rain have already fallen from Harvey, the longer range models still show in excess of another 20 inches coming from the storm over the next week. Many models indicate that more than 40 inches of rain could fall in total. And some of our best models yesterday indicated a potential for up to 60 inches in some locations by the time all is said and done.
In other words, this storm is far from over. The main event, in which Harvey may ultimately produce historic rainfall totals, is just getting ramped up. So now is not the time to relax our guard.

“Never Drive or Walk into Flood Waters – Turn Around Don’t Drown!
Flooding is one of the leading causes of weather related fatalities in the U.S. On average, flooding claims nearly 90 lives each year. More than half of these deaths occur in motor vehicles when people attempt to drive through flooded roadways. This happens because people underestimate the force and power of water, especially when it is moving.
Just six inches of fast-moving water can knock over and carry off an adult. Twelve inches of water can float a small car. If that water is moving, it can carry that car away. Eighteen to twenty-four inches of flowing water can carry away most vehicles, including large SUVs. It is impossible to tell the exact depth of water covering a roadway or the condition of the road below the water. This is especially true at night when your vision is more limited. It is never safe to drive or walk through flood waters. Any time you come to a flooded road, walkway, or path, follow this simple rule: Turn Around Don’t Drown. “

– So true…. Climate can ONLY affect so much. If someone wants to argue this, please do so ONLY after you complete the following experiment: take a foldable table and stand it up in a garden tub, small pool, or something that holds water. (This represents land and roads) Put a garden hose on top and turn in on. Start stacking bricks and/ or concrete blocks on top the table. (This represents buildings – houses and skyscrapers). After EACH layer is complete, add an extra hose that is turned on. (This represents extra water sources – bayous, sewage, ditches, etc. ) The weight will eventually buckle the table and everything will be wet and covered in water. If you you use your science and math skills, you’ll realize the land WILL sink. There are limited areas for water to go.
Construction is done at an extremely fast rate in larger areas in the city and surrounding towns. Look at the building boom in Houston, Woodlands, Tomball, Katy, Cypress, etc. It’s ridiculous to watch the number of new neighborhoods and businesses that are going in.
Consideration for safety in floods has taken a back seat. Instead of building roads up, they have them dip down where water gathers. Neighborhoods are built on and around areas where water gathers. Now do you have a better picture of the problem?

J.L.C. …the genetic inheritance I got from my father. This was a man who, while still being pursued by the police, or bankrupt, or Christ knows what, who had done prison time, then boldly stands as a parliamentary candidate. He had a huge capacity for invention. He had absolutely no relationship to the truth. He would come talk to me in the morning and I would challenge him, and in the evening he would say, “That’s not what I said to you.”
S.L. Do you see parallels with President Trump’s view of the truth?
J.L.C. Exactly that. He is the most recent model. Before that it was Robert Maxwell. The parallels are extraordinary. My sister, too, we absolutely recognize the same syndrome. There is not a grain of truth there.
S.L. Do you think the Russians really have something on Trump?
B.M. I can tell you what the veterans of the S.I.S. [the British Secret Intelligence Service, or MI6] think, which is yes, kompromat was done on him. Of course, kompromat is done on everyone. So they end up, the theory goes, with this compromising bit of material and then they begin to release parts of it. They set up an ex-MI6 guy, Chris Steele, who is a patsy, effectively, and they feed him some stuff that’s true, and some stuff that isn’t true, and some stuff that is demonstrably wrong. Which means that Trump can then stand up and deny it, while knowing that the essence of it is true. And then he has a stone in his shoe for the rest of his administration.
It’s important to remember that Putin is a K.G.B.-trained officer, and he thinks in the traditional K.G.B. way.
J.L.C. The mentality that is operating in Russia now is absolutely, as far as Putin is concerned, no different to the mentality that drove the most exotic conspiracies during the Cold War. It worked then, it works now. As far as Trump, I would suspect they have it, because they’ve denied it. If they have it and they’ve set Trump up, they’d say, “Oh no, we haven’t got anything.” But to Trump they’re saying, “Aren’t we being kind to you?”
B.M. And today you get this wonderful Russian lawyer woman [Natalia Veselnitskaya, who was in the pre-election meeting at Trump Tower with Donald Trump Jr.] who is straight out of one of our books, a character that is possibly connected to the Russian state. Who knows? They exist somewhere in that foggy, deniable hinterland. It’s called maskirovka — little masquerade — where you create so much confusion and uncertainty and mystery that no one knows what the truth is.
J.L.C. For Putin, it’s a kind of little piece of background music to keep things going. The smoking gun might or might not be the documents exchanged about the Trump Tower in Moscow [which Trump is said to have been planning to build]. Then there’s the really seedy stuff in the Caucasus. There are bits of scandal which, if added up, might suggest he went to Russia for money. And that would then fit in with the fact that he isn’t half as, a tenth as rich as he pretends to be.

“…
A study published this week in Proceedings of the National Academy of Sciences showed that among the most educated, there’s actually a deep divide in beliefs about controversial scientific issues.
The researchers analyzed public opinions on six topics—stem cell research, the big bang, human evolution, climate change, nanotechnology, and genetically modified foods—based on more than 6,500 responses from the General Social Survey (a national survey conducted once every two years.) Overall, they found that education level was “at best weakly related” to acceptance of the scientific consensus.
They write:
“We found that where religious or political polarization existed, it was greater among individuals with more general education and among individuals with greater scientific knowledge, as measured by both whether they had taken science courses and how they scored on a test of science literacy.”…”

robertscribbler
/ August 27, 2017A bit misleading (probably unintentionally). Among climate scientists, there’s practically no divide on basic causes. What this study shows is that generally more educated people tend to dig their heels in more and attempt to use data to support their views than others. In other words, it’s confirmation bias writ large.
But from the point of view of climate change itself , the various facts weigh in overwelming favor of an outstanding pile of scientific evidence supporting the fact that climate change is human-caused and that the consensus science is mostly right on the subject. There are a few outlier issues that the consensus science has some difficulty tracking. But any study of anything weather and climate related is going to have trouble nailing down the most extreme outcomes which inevitably have high levels of uncertainty involved.

“There is “extraordinarily dangerous flooding” in southeast Houston, according to Jeff Lindner with the Harris County Flood Control District.
“We are getting calls from people climbing into their attic. This is along I-45 between downtown and Clear Lake,” Lindner said. “This is along Berry Bayou, Beamer Ditch, Turkey Creek, portions of Clear Creek, Vince Bayou, Little Vince Bayou in Pasadena,” he said. “Pretty much the entire southeast side of Harris County has had 13 to 15 inches of rain in three hours.”
Lindner said they’re also seeing flooding along portions of Hunting Bayou, downtown along Buffalo Bayou, Brays Bayou and Keegan’s Bayou.
Chief Art Acevedo tweeted,” have reports of people getting into attic to escape floodwater do not do so unless you have an ax or means to break through onto your roof.”
Emergency officials warn that people should NOT go into their attics, but instead go to the roof. They also say if 911 doesn’t answer immediately, it is important to stay on the line.
“Virtually every watershed in this county, minus the extreme east side, is facing very significant flooding right now,” Lindner said.
Lindner calls the rainfall totals “staggering.””

/ August 27, 2017Thank goodness they are making this announcement. Better to be stuck out in the rain than trapped in the attic and drowning. Climb out don’t drown.

/ August 27, 2017Some models are now showing this storm moving back out into the gulf, then swinging back into Houston.

/ August 27, 2017Nothing to prevent that happening, I guess. It’s a matter of probabilities. But the huge reservoir of heat in the waters of the Gulf of Mexico makes such scenarios much more likely, it seems.
The coverage of the Weather Channel is good, but nobody is saying “global warming”. It’s a teachable moment, and the Weather Channel that is a commercial operation relying on advertising is apparently afraid of offending the Trump supporters and climate science deniers. But, the message is getting through to most people, anyway, I think.
Earth Nullschool is projecting using GFS continuing heavy rainfall in the area at least through early September:

/ August 27, 2017Lack of high level wind shear is allowing the system to hover and stay somewhat organized.
Is a lack of high level wind shear related to global warming? Dunno. What would Jennifer Francis say about this, I wonder?

/ August 27, 2017Is this flooding event possibly connected to the general slowdown of jet stream planetary waves? I wonder what the experts like Michael Mann and Jennifer Francis are saying about Harvey?

/ August 27, 2017Leland, my understanding is that, no, GW actually corresponds to higher windshear more often. That’s why they do not expect there to be more _frequent_ hurricanes, even though there will otherwise be more conducive conditions for their formation. But when the wind shear happens not to show up to cut them apart, we are more likely to see the hurricanes that do develop turn into these kinds of monsters. That’s my understanding anyway. Others can correct and or supplement if so inclined.

/ August 27, 2017It’s generally unclear. At 1-2 C there does appear to be generally more shear. But long periods of atmospheric stagnation and regions of very low shear can also tend to emerge.

/ August 27, 2017As well as jet stream slowdown and stalling, there is also a lot of just breaking up and splitting of the jets. I I don’t know how that aspect could be measured, but it would seem to add more uncertainty to predictions based on a predominately intact, but slower jet.

/ August 27, 2017Stupid question: one of the models that shows this thing going back out to sea indicates that central pressure will dip below 1000 mbs again. Is that part of a definition of a hurricane, or is it just windspeed that counts. Couldn’t find much on this with a cursory search.

/ August 27, 2017The two primary measures of intensity for hurricanes are wind speed and barometric pressure. Barometric pressure is a measure of the overall strength of the system, regardless of wind speed. Smaller storms with higher pressures can have higher wind speeds. Larger storms with relatively lower pressures can have somewhat lower wind speeds. For example, you could have a very large 935 mb storm that’s a minimum category 4 when it comes to winds speed (130 mph) but that has more energy overall than a much smaller 940 mb storm that has winds approaching Category 5 intensity (155 mph). Wind speed itself is what determines category. However, barometric pressure generally determines overall energy in the system.

/ August 27, 2017Thanks. I guess will have to wait to see if it’s a hurricane that develops or not. Whatever it is, and wherever it goes, it does seem to be about to pile even more rain on an already catastrophically flooded area. Quite the horror show…

/ August 27, 2017If Harvey stays near the coast, it’s unlikely to reform into a Hurricane. Usually pressure has to fall to around 970 to 980 mb for that to happen.

/ August 28, 2017The drop in pressure as wind speeds increase is a result of Bernoulli’s principle. Generally as the speed of a gas increases the pressure drops:

Temperature was forecast here in Cottage Grove, OR to get close to 100F today but smoke from the wildfires is so thick we will probably not get over 85F. What a devil’s bargain. Roast in the heat or feel the burn in your lungs.
The floods in Texas are quick and devastating. Wiping out people and property. The drought here is slower and more insidious, year after year gradually turning the land into a strange type of desert where we get heavy rain for about 3 months and then high temps and zilch rain for months on end.
Human induced climate change? Oh yeah. No doubt about it!
