On Monday, Nick Gemayel was seated at his office desk in his Rochester, New York auto repair shop when he saw a bright flash spark from a light switch and heard a loud crack. Then he realized that his hand hurt like hell was blistered. A co-worker reported that he had seen lightning strike the building. It apparently arced from the light switch into Gemayel. Hospital doctors treated and released him. No word yet on what superpowers he may now have.

Chad Cowan shared this taste of his upcoming long-form timelapse of massive thunderstorms sweeping across the American plains.
He gives a little background on how he was inspired by Tom Lowe:
This collection of timelapses was gathered over the last six years. The project started out as wanting to be able to see the life-cycles of these storms, just for my own enjoyment and to increase my understanding of them. Over time, it morphed into an obsession with wanting to document as many photogenic supercells as I could, in as high a resolution as possible, as to be able to share with those who couldn't see first hand the majestic beauty that comes alive in the skies above America's Great Plains every Spring. After more than 100,000 miles on the road and tens of thousands of shutter clicks later, this is the result. I hope you enjoy watching it as much as I enjoyed creating it. Keep an eye out for a long form version of my storm timelapses, as these are a small sample of what I've been able to gather. I'm not sure yet how the extended version will be released.

The incessant rain in California for the last several weeks is just a taste of what's to come in the formerly drought-plagued state, says Rachel Becker in The Verge.
The most recent was a series of storms that lasted for a near-biblical 43 days between 1861 and 1862, creating a vast lake where California’s Central Valley had been. Floodwaters drowned thousands of people, hundreds of thousands of cattle, and forced the state’s government to move from Sacramento to San Francisco.
More than 150 years have passed since California’s last, great flood — and a team of researchers with the US Geological Survey have predicted what kind of damage a similar flood would cause today. Their simulation, called the ARkStorm, anticipates that a stretch of the Central Valley 300 miles long by 20 miles wide would be underwater. Cities up and down the coast of California would flood. Winds would howl 60 to 125 miles per hour, and landslides would make roads impassable.

As I nod off at my desk I begin to day dream about the breathtaking beauty of the American Southwest. Suddenly I am whisked away to this enchanting land of red rock hoodoos and truly grand canyons as far as the eye can see. Much of this magnificent area has an elevation of 8000-10,000 ft above sea level and with no city in sight for hours - the skies are so dark that viewing our galaxy is as easy as opening our eyes and looking up.
This film was captured while in Southern Utah and Northern Arizona this past September and early October. I was leading two advanced timelapse workshops (TimelapseWorkshops.com), and spent another few days ahead of time scouting locations with my guest instructor, Sean Parker.
In total we drove over 30 hours to get to all of these locations - yet each minute was filled with anticipation of what mother nature would bring.
Anyone who has met me knows my love for the southwest. I have been photographing this area for the past 20 years and since launching my timelapse workshops in 2013 I continue to attract amateur and professional photographers from all over the world (including Brazil, Turkey, China, Denmark, Scotland, and the United States) who fly in to learn how to capture and create breathtaking time lapses using their DSLR's.
Cameras on the International Space Station captured this footage of three major hurricanes on Earth on August 30. Two of these storms are in the Pacific Ocean, and one is in the Atlantic Ocean.

Is Los Angeles prepared for the El Niño storms we're getting? An #ElPolloLoco in Lincoln Heights wasn't. Jacqueline Garcia shot this video of the roof about to collapse from the rain at about 1pm today, LA time.
“They evacuated people but when rain stopped they reopened,” she says.

Typhoon Haiyan approaching the Philippines (13:00 UTC 07/11/2011). Image captured by the geostationary satellites of the Japan Meteorological Agency and EUMETSAT.
The powerful storm named Super Typhoon Haiyan (or Super Typhoon Yolanda, as it is referred to within the Philippines) hit the central islands of the Philippines on Friday, with reported wind speeds of 190 to 195 miles per hour at landfall. For comparison, a commercial airplane takes off at speeds in the range of 160mph.
Haiyan is reported to be the strongest typhoon in the world in 2013, and may be the most powerful recorded tropical cyclone to ever hit land. Read the rest
Atmospheric rivers are meteorological phenomenon that we humans only discovered in 1998 and which supply about 30-to-50 percent of California's annual precipitation. In the NOAA satellite image above, the atmospheric river is visible as a thin yellow arm, reaching out from the Pacific to touch California. Or, more evocatively, reaching out to slap California silly with a gushing downpour.
An atmospheric river is a narrow conveyor belt of vapor about a mile high that extends thousands of miles from out at sea and can carry as much water as 15 Mississippi Rivers. It strikes as a series of storms that arrive for days or weeks on end. Each storm can dump inches of rain or feet of snow.
The real scare, however, is that truly massive atmospheric rivers that cause catastrophic flooding seem to hit the state about once every 200 years, according to evidence recently pieced together (and described in the article noted above). The last megaflood was in 1861; rains arrived for 43 days, obliterating Sacramento and bankrupting the state.
As you might guess, climate change is also involved. Evidence suggests that warming global temperatures could increase the frequency of atmospheric rivers. That, combined with the 200-year event expected soon and the fact we're learning so much much more about these storms, means that you should expect to hear the phrase "atmospheric river" more often.
Scientific American has two interesting stories on the phenomenon right now. The first, which I quote from above, is a blog post by Mark Fischetti. Read the rest
The more accurate version of this question would really be something like, "Why do some trees fall over in a storm while others stay standing?" The answer is more complex than a simple distinction between old, rotted, and weak vs. young, healthy, and strong. Instead, writes Mary Knudson at Scientific American blogs, trees fall because of their size, their species, and even the history of the human communities around them.
“Trees most at risk are those whose environment has recently changed (say in the last 5 – 10 years),” Smith says. When trees that were living in the midst of a forest lose the protection of a rim of trees and become stand-alones in new housing lots or become the edge trees of the forest, they are made more vulnerable to strong weather elements such as wind.
They also lose the physical protection of surrounding trees that had kept them from bending very far and breaking. Land clearing may wound a tree’s trunk or roots, “providing an opportunity for infection by wood decay fungi. Decay usually proceeds slowly, but can be significant 5-10 years after basal or root injury.” What humans do to the ground around trees — compacting soil, changing gradation and drainage “can kill roots and increase infection,” Smith warns.

The images above — prepared by NASA hurricane researcher Owen Kelly — were taken on Sunday, before Hurricane Sandy made landfall on the United States' Northeast coast. They're made from radar data collected by the Tropical Rainfall Measuring Mission (TRMM) satellite, and they show a feature of this storm that helps explain why it's caused much more destruction than you might expect from a Category 1 hurricane.
In the right-hand image, showing a close-up of the storm's eye, you can see a feature labeled "eyewall". Those are vertical cloud walls that surround the eye, and they're the spot with the strongest winds in the whole storm.
Placed in context, the TRMM-observed properties of Hurricane Sandy’s eyewall are evidence of remarkable vigor. Most hurricanes only have well-formed and compact eyewalls at category 3 strength or higher. Sandy was not only barely a category 1 hurricane, but Sandy was also experiencing strong wind shear, Sandy was going over ocean typically too cold to form hurricanes, and Sandy had been limping along as a marginal hurricane for several days.
That eyewall, says NASA and New Scientist, is the result of Sandy's Frankenstorm nature. Despite all the factors that should have made this storm weak, it represented the merging of several storm systems. Because of that, Sandy was stronger than a Category 1 storm normally is.

Tornado-loving BB pal Jody Radzik just turned me on to Extreme Instability, a collection of one intrepid storm chaser's breathtaking weather photography. The above photo that I've taken it upon myself to title "Act of God" is from a bow echo in Watertown, South Dakota on August 3. The photographer: "I'm driving along, having gained at least a small bit of ground again, when I see this white cross and a roadside chapel next to the road. No way. Slam on the brakes, pull over and jump out of the car and shoot fast fast." Extreme Instability Read the rest
During the storm a couple of nights ago, we heard an almighty thunderclap and our dogs came dashing into the house. Once the rain ebbed and we went outside, we found this scene just around the corner: a wall apparently blown to pieces, with cinderblock chunks thrown as far as 40 or 50 feet. It seems too far for a plain old wall collapse. Could that have been caused by the lightning strike? If so, how? Steam pressure from the waterlogged bricks being suddenly superheated, like a tree strike? Read the rest
