A lot of washed out roads to the north and east of me over the last 24 hours or so.

Any extreme weather happening in anyone else's area recently?

Last Thursday and Friday we experienced two separate storm systems, the first dumped 1.9 inches of rain upon us in two hours and the second the next day gave us another 1.1 inches in a downpour lasting not much over 90 minutes in duration.

Wow. Thanks for the info. Presumably part of this same system.

We got another inch of rain between midnite and 5 am today, the fields in these parts are again flooded. If this keeps up the soybean harvest is going to be hurt.

New Nova tonight on PBS (in my market):

"Rise of the Superstorms"

In just one devastating month, Houston, Florida, and the Caribbean were changed forever. In summer 2017, three monster hurricanes swept in from the Atlantic one after another, shattering storm records and killing hundreds of people. First, Harvey brought catastrophic rain and flooding to Houston, causing $125 billion in damage. Less than two weeks later, Irma lashed the Caribbean with 185 mile per hour winds—and left the island of Barbuda uninhabitable. Hot on Irma’s heels, Maria intensified from a Category 1 to a Category 5 hurricane in just 15 hours, then ravaged Puerto Rico and left millions of people without power. As the planet warms, are these superstorms the new normal? How well can we predict them? And as the U.S. faces the next hurricane season, does it need to prepare for the reality of climate refugees? NOVA takes you inside the 2017 superstorms and the cutting-edge research that will determine how well equipped we are to deal with hurricanes in the future.

Thanks for that link, G, and that info on local conditions, T. IIRC, more crops are lost in most years from too much rain than from drought. Both will be taking their toll more and more frequently going forward.

Meanwhile, here's an excerpt from the new book Rising:

https://www.theguardian.com/environment ... s-flooding

Meet America's new climate normal: towns that flood when it isn't raining

In this extract from Rising, Elizabeth Rush explains ‘sunny day flooding’ – when a high tide can cause streets to fill with water

...It isn’t raining when I arrive in Shorecrest, and there isn’t a storm offshore; the day is as clear and as blue as the filigree on a porcelain plate. But the streets are still full of water. I watch as a woman wades ankle deep across Tenth Avenue. She has gathered her long russet-colored skirt in her right hand, and in her left she holds a pair of Jesus sandals. When she reaches the bus stop, she sits and puts her shoes on.

“We get flooded with just about every high tide,” the woman tells me. “And if the moon is big it’s worse.”

All along the east coast, from Portland, Maine, to Key West, “sunny day flooding” is increasingly frequent. Many places in the Sunshine State are so low lying that high tide – when coupled with something as innocuous as a full moon – can cause the streets to brim with water. Sometimes the tide simply rises above the seawalls and starts to spill into the roadways; in other cases it enters the neighborhood through the storm-water infrastructure below ground.

The very pipes designed to reduce flooding by ushering rain out instead give salt water a chance to work its way in...

...a man walks up behind me, peers down, and says: “I’ve seen fish come swimming out.”

“No, you haven’t!”

“I have,” he says, pushing his sunglasses up.

I’ve been here 20 years. When I first moved we used to flood once a year, maybe twice. Now it’s constant”...

"...we have to start preparing for inundation.

Remember, the last time carbon dioxide levels were the same as they are today, the ocean was one hundred feet higher".

Good catch, ol. Here's an update, and things are looking much worse:

Japan Reels From Heavy Rains; Dozens Killed and Millions Evacuated


Record torrential rains across western and central Japan unleashed flooding and landslides in several residential areas, killing dozens and triggering weather warnings in four districts of the country.

By Saturday evening, at least 51 people were dead and 48 were missing, according to the public broadcaster NHK. More than one million people in 18 districts had been ordered to evacuate their homes and 3.5 million had been urged to leave.

The Japan Meteorological Agency reported on Saturday that rainfall in many of the affected areas had reached record levels — with some areas reporting rain two or three times as high as the monthly average for all of July over just five days...


https://www.nytimes.com/2018/07/07/worl ... lides.html

"44 inches of rain fell on Yanasa in Umaji village, Kochi prefecture, on Shikoku, in only three days - that's double the total amount that usually falls in the whole of July."

Juice the atmosphere more and more, you get more/bigger rain bombs.

Yeah, extreme rain events (deluges!) of forty inches and more are becoming a thing, if not quite the new normal yet, as someone on asif just pointed out: Harvey last year, Kauai earlier this year, and now Japan.

Does anyone know of other such events that have happened anywhere?

ETA: Some quick research coughed up this tidbit: "Cherrapunji [India] holds the world record 48-hour rainfall with a whopping 2,493 mm, or 98.15 inches, of rain on June 15-16, 1995"

I guess the odd thing about these other events is that they are outside of the usual monsoon areas, as far as I understand. Also, they're all happening within about a year of each other.

Another one to add to the long file labeled: "faster (more intense...) than expected consequences of AGW":

Australia facing extremely intense rain storms.
Landmark study shows how heavy, short rain storms are intensifying more rapidly than would be expected with global warming. Jul 30, 2018. Newcastle University
https://www.sciencedaily.com/releases/2 ... 120245.htm

The team of international scientists, led by Dr Selma Guerreiro at the School of Engineering, Newcastle University, UK, has for the first time found increases in short, intense rain storms over Australia over the past 50 years.
The storms are substantially larger than would be expected under climate change.
Published today in Nature Climate Change, the study shows that in Australia:
1, Extreme daily rainfall events are increasing as would be expected from the levels of regional or global warming that we are experiencing
2. the amount of water falling in hourly rain storms (for example thunderstorms) is increasing at a rate 2 to 3 times higher than expected, with the most extreme events showing the largest increases.
3. large increase has implications for the frequency and severity of flash floods, particularly if the rate stays the same into the future.

Professor Seth Westra, co-author from the University of Adelaide, Australia, said:
“These changes are well above what engineers currently take into account when determining Australia’s flood planning levels or designing stormwater management and flood defence infrastructure.
“If we keep seeing this rate of change, we risk committing future generations to levels of flood risk that are unacceptable by today’s standards.”
