Comment: This was the first deadly tornado in Uruguay in 30 years.


A tornado ripped through the southwestern city of Dolores in Uruguay, killing four people and leaving hundreds injured, government officials said. More than 200 people suffered injuries and about 400 structures have been affected, said Uruguayan Sen. Guillermo Besozzi. Images from the city showed overturned cars piled on top of one other, shattered windows and decimated buildings.


The tornado hit the city around 4 p.m. local time Friday. The National Institute of Meteorology has yet to determine the scale of the tornado."There are businesses in the center of the city, completely destroyed. Schools, churches destroyed. This is something never seen before. This is something out of the normal for our country," Besozzi said.

Mariela Umpiérrez, a resident of Dolores, told CNN en Español that her house, office car and those of her relatives were damaged. "The images seems taken out of a movie, but not from reality," she said. The Uruguay government pledged to send emergency help to the affected areas. There have been some looting in the area, but the government has sent officers to address it, Besozzi said.

Rains and flooding have killed 18 people throughout Saudi Arabia and 915 had to be rescued from inside their vehicles, the General Directorate of Saudi Civil Defense said on Thursday.

Floodwaters inundated roadways in Riyadh, Mecca and the mountainous south of the mostly desert kingdom, the directorate said in a statement.

Videos posted on social media showed cars submerged in water in the southwestern city of Abha.

Heavy rains have lashed Saudi Arabia for several days and the education ministry closed schools in and around the capital Riyadh on Wednesday.

Baseball-size hail slams Texas for second consecutive day

For the second day in a row, a major hail storm slammed parts of Texas Tuesday, causing widespread damage across the state.

The National Weather Service received over 30 hail reports from the Lone Star State Tuesday, ranging from 1" to 3.5" (bigger than baseball-size).

"High CAPE values and steep lapse rates allowed for the formation of very large hail in Texas over the last two days," explains Weather Network meteorologist Dayna Vettese. "CAPE is 'Convective Available Potential Energy', which is the energy available in the atmosphere for storms to use. Lapse rate is a term used to describe the temperature change as you going up from the surface into the atmosphere. The bigger (or steeper) that temperature change, the stronger the rising motion in the atmosphere. In order for large hail to form, you need strong rising motion; strong enough to keep hail stones suspended in the air long enough to grow large."

The storm was part of an ongoing system that's been slamming the Texas and the Gulf States with heavy rain and strong winds for the last couple of days.

Record breaking rain causes flash floods in Las Vegas, over a hundred road crashes

flash flood las vegas
Record-breaking rain drenched Las Vegas throughout the weekend, causing flooding and more than a hundred crashes on the roads.

Flash flood warnings were issued Saturday, when 0.81 inch of rain was recorded at the National Weather Service's official measuring site at McCarran International Airport in Las Vegas. That handily beat Sin City's previous record for the day, which was set at 0.17 inch in 1943, said Andrew Gorelow, a meteorologist.

It now also ranks as the third-highest total amount of rain ever for a single day for the month of April.

"April is one of our driest months of the year," Gorelow said. "We only average 0.15 (inch) for the average month (total)."

Sunday also broke the day's record with 0.14 inch of rain, washing out the previous record of 0.13 inch set in 1943. Gorelow said the rain was caused by a low pressure system that had picked up a lot of moisture on the way in from Southern California.

Baseball-sized hail stones battered Texas on Monday, smashing windows, cars, and buildings.

Footage shared by people in Dallas, Fort Worth, Wylie and Denton showed astonishing clumps of ice bigger than an adult hand that fell during one of the worst storms the region has seen in months.

It all appeared to come from an ominous-looking green shelf cloud, which shone a luminous glow over northern Texas.

The damage drove officials in Wylie, which is 10 miles east of Plano, to close all schools on Tuesday.

Damage: This house is one of many houses left completely shattered by the intense ice clumps

Massive 2015 Alaskan landslide triggering mega-tsunami estimated to be biggest non-volcanic landslide in North American history

landslide tyndall glacier
After a period of heavy rains, about 200 million metric tons of rock tumbled down a remote Southeast Alaska mountain. The massive landslide, lasting about 60 seconds, occurred on October 17, 2015, and landed on the toe of Tyndall Glacier and into Taan Fiord in Icy Bay, Alaska.

The event generated a local megatsunami that sheared trees more than 152.4 meters (500 feet) up on a peninsula within the fiord. It was big enough to register at the nearest tidal gauge 155 km (96.3 miles) away. For comparison, the 2011 tsunami in Japan reached about 39.6 meters (130 feet) above sea level.

This event, now estimated as the biggest nonvolcanic landslide, by volume, in North America's written history, was registered by special seismograms monitored by the Global CMT Project at Lamont-Doherty Earth Observatory whose seismologists Göran Ekström and Colin Stark have invented a new technique that uses seismic waves to detect landslides in remote areas where they might otherwise go unrecorded.

Movement of water around the world contributes to Earth's rotational wobbles says NASA

Earth's Spin Axis
© NASA/JPL-CaltechEarth does not always spin on an axis running through its poles. Instead, it wobbles irregularly over time, drifting toward North America throughout most of the 20th Century (green arrow). That direction has changed drastically due to changes in water mass on Earth.
Using satellite data on how water moves around Earth, NASA scientists have solved two mysteries about wobbles in the planet's rotation -- one new and one more than a century old. The research may help improve our knowledge of past and future climate.

Although a desktop globe always spins smoothly around the axis running through its north and south poles, a real planet wobbles. Earth's spin axis drifts slowly around the poles; the farthest away it has wobbled since observations began is 37 feet (12 meters). These wobbles don't affect our daily life, but they must be taken into account to get accurate results from GPS, Earth-observing satellites and observatories on the ground.

In a paper published today in Science Advances, Surendra Adhikari and Erik Ivins of NASA's Jet Propulsion Laboratory, Pasadena, California, researched how the movement of water around the world contributes to Earth's rotational wobbles. Earlier studies have pinpointed many connections between processes on Earth's surface or interior and our planet's wandering ways. For example, Earth's mantle is still readjusting to the loss of ice on North America after the last ice age, and the reduced mass beneath that continent pulls the spin axis toward Canada at the rate of a few inches each year. But some motions are still puzzling.
