Waterspout at Lake Ouchita in Arkansas - May 30 2013
A waterspout is an intense columnar vortex (usually appearing as a funnel-shaped cloud) that occurs over a body of water, connected to a cumuliform cloud.
The eyewitness video shows the biggest waterspout many Grand Isle neighbors have ever seen, which stroke off the coast of the Gulf of Mexico in Grand Isle, Louisiana, yesterday, June 19 2013. Here is the amazing video of this water twister captured by someone that lives in Grand Isle.
You can get a good idea of what is a waterspout and how they form here. For some reason these waterspouts form quite a bit in the Grand Isle/Port Fourchon area.
The first thunderstorms started in Graubünden and spread over the Rhine Valley to Zurich, Winterthur and Eglisau, where it was the strongest.
Hail was accompanied by stormy gusts of wind of up to 96 kmh.
The astronomers studying the atmosphere of Venus are facing a new mystery. The Venusian winds have been steadily accelerating for the last 6 years. Scientists monitoring the Venus Express orbiter since 2006 noted the stunning increase in the already super fast winds, from 186 mph to 249 mph. The astronomers acknowledge they do not understand why this enormous variation in wind speed occurred. What is it about the Venusian atmosphere that mainstream astronomers find so puzzling?
What appeared to be an unusual and unexpected storm turned out to be a cloud of dirt, dust, pollen, bugs and even birds.
National Weather Service forecasters in Dallas-Forth Worth Texas picked up the strange phenomenon on their radar on Friday while the weather remained hot and dry, reaching record highs of 105 and 106 degrees in the Austin area to the south.
'It looked like it was raining,' Jennifer Dunn, a meteorologist for the weather service office that covers the Dallas-Fort Worth region, told the Austin American-Statesman.
'We thought something was wrong with the radar, but we checked our instruments and measurements. Everything was working fine.'
Dunn and her colleagues said their best guess was that the anomaly was a giant swarm of bugs.
But a meteorologist for the weather service office in New Braunfels, which includes Austin, told the Statesman that insects likely made up less than 1 per cent of the unusual matter in the air over the Dallas-Fort Worth area.
A freak hailstorm over one of the biggest Nato airbases in Afghanistan grounded more than 80 helicopters, putting several of them out of action for more than three weeks, it has emerged.
The half-hour storm in late April split rotor blades, cracked windows, ruptured the choppers' metal skin and damaged other parts. The hail was so intense that after an intensive repair programme eight of the choppers were still inoperable more than three weeks later, according to a Nato spokesman.
Videos show hailstones the size of golf balls pelting down on the airbase, which is at the edge of a desert and in summer endures temperatures that can climb above 50C.
"Everybody was notified and told to evacuate," said Butler County emergency management coordinator Mitch Nordmeyer as he surveyed the town, about 90 miles northeast of Des Moines. "If they stayed they were staying at their own risk."

Residents had seen the normally placid Beaver Creek flood before. And after some areas upstream received more than 7 inches of rain on Monday, few seemed surprised the stream was surging out of its banks again.
Winds of up to 140km/h - gusting to 200km/h in exposed areas - lashed Wellington, felling trees, lifting roofs, smashing windows, closing roads and schools and cutting power to homes and businesses.
The highest rainfall in the region was recorded in Karratha, where 209.2mm of rain has fallen since 9am yesterday.
The rainfall smashed Karratha's daily June record of 60mm.
