Verenigde Staten getroffen door meer dan 50 tornado's in 24 uur tijd
Hevige tornado's houden de Verenigde Staten in de greep voor de twaalfde dag op rij. In 24 uur tijd raasden meer dan 50 tornado's door 8 verschillende staten. Ohio en Indiana zijn het zwaarst getroffen. Eén man kwam om het leven, 130 mensen raakten gewond en de materiële schade is enorm. Vijf miljoen mensen zitten zonder stroom.

In de stad Dayton in Ohio is de ravage enorm. Delen van de stad zijn volledig verwoest, huizen, elektriciteitspalen en ontelbare bomen gingen tegen de grond. Een 82-jarige man kwam om toen een geparkeerde auto in zijn huis sloeg.

Er werden windsnelheden opgetekend tot 225 kilometer per uur. In Oklahoma en Arkansas zijn rivieren buiten hun oevers getreden en staan hele buurten onder water. Het einde van het noodweer is nog niet in zicht.

"Tornado Alley"
De Verenigde Staten worden nu al twee weken geteisterd door een ongeziene reeks tornado's. Die razen vooral door het midwesten, dat trouwens bekend staat als "Tornado Alley". Het extreme weer wordt veroorzaakt door een mix van warme, vochtige lucht uit het zuidoosten en ongewone kou uit de Rocky Mountains. Maandag werd het huidige record verbroken van minstens acht tornado's per dag, gedurende 11 opeenvolgende dagen.

Dit jaar hebben 10 tornado's al het leven gekost aan 38 mensen in de VS. Ter vergelijking: in 2011 kwamen 161 mensen om en raakten er meer dan 1.100 gewond door een gigantische tornado in Missouri.

President Trump, die op staatsbezoek is in Japan, heeft via Twitter laten weten dat hij de situatie op de voet volgt.

EF2 tornado rips through Dallas
An EF-2 tornado left major damage on structures and power towers in Dallas, USA on Sunday night, October 20, 2019. Authorities urged commuters to avoid affected areas as emergency services are conducting major roadway repairs.

According to the National Weather Service, the twister touched down near Love Field Airport around 21:30 LT before heading northeast through the city. No fatalities or injuries were reported as of 00:20 LT the following day, October 21, until the system pushed up through Arkansas killing one person.

ICT: 2019 Dallas tornadoes the costliest tornado event in Texas history, USA

A tornado outbreak that hit Dallas on October 20, 2019, is now the costliest tornado event in the history of Texas and the 11th weather disaster in the USA in 2019 whose damage topped 1 billion dollars.

The Insurance Council of Texas (ICT) has estimated about $2 billion in insured losses following 9 tornadoes that ripped through North Texas on Sunday, October 20.

Preliminary projected estimates include over 30 000 auto and home claims. Commercial and business claims projections are still coming in at this time and the financial impact may likely rise.

"This makes the October 20th Dallas tornado outbreak the costliest tornado event in Texas history," ICT said.

In contrast, the Garland/Rowlett tornado of December 26, 2015, resulted in insured losses of $1.2 billion dollars.

"Sunday’s tornadoes, however, extended over a wider geographic span impacting a variety of homes and commercial property. The multiple tornadoes uprooted decades-old trees, brought down power lines, made many roads impassable and immeasurably changed the landscape of some neighborhoods."

Thankfully, despite the large scale property damage, there were no fatalities.

An EF-3 tornado was the first [and strongest] in the series of twisters which swept across a path almost 26 km (16 miles) in just over 30 minutes through the northern area of Dallas county. According to the National Weather Service, it had maximum winds of 225 km/h (140 mph).

Furthermore, Garcia called $2 billion a "pretty conservative estimate" since the twisters did not just cause destruction to residential properties in North Dallas, but also to commercial establishments.

However, insurance industry meteorologist Bryan Wood does not agree with the figures. "Given that the majority of the damage in the tornado is EF-0 or EF-1, I believe that a $2 billion damage estimate is too high," he tweeted.

Wood added, "For comparison, the Joplin tornado, which had a much larger proportion of damage at EF3-plus, was $2.8 billion."

"From what I’ve seen, a lot of varying degrees of roof damage is the biggest damage mode. It does add up – but probably closer to $1 billion than $2 billion."

Teams from the National Weather Service fanned out across Alabama on Sunday to assess storm damage from Saturday’s severe weather.

As of Sunday night five tornadoes have been confirmed: Three in north Alabama and two in central Alabama -- including the deadly Pickens County storm.

The National Weather Service in Birmingham said its survey team confirmed a tornado hit Pickens County near Carrollton and gave it a preliminary rating of EF2 with top winds of 134 mph.

The Pickens County storm is being blamed for three deaths and seven injuries on Settlement Road near Carrollton.

The survey team from Pickens County has sent back a preliminary report that the damage they are seeing is rated at least EF2, at 134 mph. The survey is still ongoing, and more details will be shared when it is available. #alwx

That tornado touched down at 11 a.m. less than 2 miles east of Pickensville and was on the ground for 6.33 miles, according to a preliminary report from the weather service, lifting just less than 7.5 miles southwest of Reform. It was 1,056 yards wide at its peak.

Several homes were damaged along the path, but the tornado likely peaked in intensity along Settlement Road. The weather service said numerous homes were damaged or destroyed on the west side of Settlement Road, while homes on the east side of the road received minimal damage.

According to the weather service, “of the homes destroyed, six were site-built homes. Four manufactured homes were completely destroyed, three of which had anchoring systems that failed. All four manufactured home frames were found considerable distances from the home sites. Three fatalities occurred in two of these manufactured homes on Settlement Road."

All of the injuries occurred on Settlement Road, according to the report. However, other homes not on that road were also damaged. A total of 22 homes were damaged in some way, according to the weather service.

Experts predict near- to above-average tornado activity this spring

Every day that passes, the calendar draws nearer to spring — peak tornado season for much of the central and eastern United States. And atmospheric scientists have cast their predictions for tornado season 2020, calling for a near to slightly more active season than average. There are also signs that peak periods of storminess could ramp up earlier in the year than during some previous seasons.

Victor Gensini, a professor of atmospheric sciences at Northern Illinois University, said he gently leans toward an above-average tornado season.

Genisini rose to prominence in the field of seasonal forecasts for severe weather in recent years, most recently predicting 2019′s record tornado onslaught nearly four weeks in advance. He specializes in determining how “teleconnections,” or the presence of distant and seemingly tangential atmospheric features, can have impacts on weather closer to home.

An average to above-average season
This year, he’s forecasting bouts of severe weather to begin increasing in frequency and intensity during March and April. May looks to be a busy month as well.

“If the current pattern doesn’t change significantly, we could be up for … periods of intense activity, followed by shutdowns,” he explained. Predicting exactly when those busy spurts will line up is a bit more challenging. “It’s going to coincide with where we are in the sub-seasonal cycle.”

Gensini alludes to smaller-scale, shorter-duration atmospheric disturbances that can bolster or inhibit storminess over the Lower 48. In past years, there have been larger, more obvious ingredients in place. But not so much this year. The atmosphere will be a bit more fickle.

“Last year it was very obvious when the stars would align,” Gensini said. “I think usually by March 1, things become pretty clear. Are there any sort of ‘big players?’ I kind of think of [the atmosphere] as a big orchestra … all the instruments playing together in an ensemble. Some years, you have some instruments playing louder than the others and controlling the narrative and the tune.”

John Allen, a professor of meteorology at Central Michigan University, says the “big player” is usually from El Niño or La Niña.

“If you think about how these systems are connected, we’re thinking here about a cascade of scales,” said Allen, discussing the link between large-scale climate systems and the comparatively fleeting nature of tornadoes and severe thunderstorms. “El Niño interacts on a scale of several thousands of [miles], with interactions going through a middle man.”

That middle man? The jet stream.

The jet stream’s role
In order for supercells — rotating thunderstorms — and tornadoes to form, two ingredients must be present in the atmosphere: instability, and wind shear.

An unstable atmosphere, caused by vertical temperature contrasts, results in lifting motion that can give rise to thunderstorms. To get those storms to spin, you need wind shear — a change in wind speed and direction with height. And when the jet stream is nearby, there’s usually plenty of wind shear present. The jet stream is a swift current of rapidly moving air in the upper atmosphere. Jet stream speeds can occasionally top 150 mph.

As winds near the ground generally don’t approach speeds of that magnitude, there’s a significant change of wind speed with height in the vicinity of the jet stream generating wind shear.

Disturbances embedded within the jet can trigger bouts of severe weather, since jet stream meanderings usually carry cold air aloft. That’s a key factor in thunderstorms. The wind shear imparted by the jet, meanwhile, can encourage storms to rotate.

Connection to El Niño and La Niña
Long-range severe weather forecasts don’t start in Tornado Alley. In fact, they don’t even start in the United States. The first place to look? The Pacific Ocean.

Water temperatures in the tropical Pacific Ocean can have enormous bearings on our weather. Water temperatures there fluctuate in response to the El Niño Southern Oscillation, or ENSO. During El Niño, water temperatures over the eastern equatorial Pacific run anomalously warm; those same seas are atypically cool during La Niña.

ENSO, sort of like a pendulum, can swing irregularly between the two states every few years. Knowing a bit about the status of El Niño or La Niña generally offers insight as to how the jet stream will behave.

[January was the most unusually warm month ever recorded without an El Niño]

The warm East Pacific waters that occur with El Niño help steer moisture from the subtropics across the Baja Peninsula, and eventually over the northern Gulf of Mexico. That can increase low cloud cover and lower temperatures. Meanwhile, the energized polar jet stream is diverted far to the north, where it’s far removed from the key zones for severe weather. Without the polar jet’s added wind shear, hail and tornado chances on the Great Plains decline. Allen and his team showed this in 2015.

La Niñas, on the flip side, bring warmer and drier conditions to the southern United States, and colder weather to the north. That temperature clash can brew severe storms. And a polar jet lurking nearby can help spin up tornadoes — especially in the eastern Plains.

This year, however, ENSO looks to be “close to neutral,” according to Allen.

“ENSO is a dominant mode for most seasonal forecasts,” Allen said. “[This season] you don’t have the main predictor that’s pulling the strings.”

More subtle weather features may dominate this season’s forecast

With no dominant ENSO influence, the focus shifts to other features.
Those more subtle features are a lot more finicky and tougher to predict. Plus, they’re much more difficult to spot from a distance. Gensini, however, already has his eyes on something.

“There’s a lot of convection anchored near the equatorial international date line,” said Gensini, referencing a batch of showers and thunderstorms in the central Pacific. It’s tied to a region of above-average water temperatures. “If that warm pool continues into the spring, I’d have reason to consider an average to an above-average season.”

The warm pool could influence the position and strength of the jet stream enough to shape the Lower 48′s severe weather season.

“The positioning of the jet stream across the U.S. is vital for springtime severe weather frequency,” Gensini said.

Gensini and Allen alike hope these predictions will help emergency managers better plan and prepare for dangerous bouts of severe weather.

“FEMA could benefit in moving around assets or resources,” said Gensini, on the benefits of seasonal tornado forecasts. “Insurance companies could model potential losses. These forecasts are targeted toward educators, administrators, [emergency managers] — the folks that are sort of spreading the message and creating a weather-ready nation.”

Nashville tornado kills at least two, hits CBS affiliate directly

A tornado near downtown Nashville early Tuesday killed two people, police said, and hit the CBS affiliate in the city directly. WTVF-TV described damage around town as extensive.

The city's emergency operations center was activated. An emergency shelter was set up. Residents were urged to avoid downed power lines. Electricity was out in many areas.

Schools were closed for the day but polling stations for the Super Tuesday primary were to stay open.

The twister was one of at least two that touched down in central Tennessee. The one near downtown reportedly stayed on the ground into Hermitage, about 10 miles east of the city.

A video posted online from east Nashville showed what appeared to be a well-defined tornado moving quickly across the city. Lightning repeatedly flashed while much of the city was in the dark. The whirl of the wind could be heard gusting after the tornado moved out of sight.

Mississippi hit with two ‘catastrophic’ EF5 tornadoes at the same time: ‘This is flattening everything in its path’

The southeastern United States is being pummeled with tornadoes, but the largest storm, an EF5 tornado, has already killed at least six people in Mississippi.

One person suggested it was the most destructive tornado since Joplin, Missouri in 2011, but Oklahoma had two EF5 tornadoes after that in May 2011 in El Reno and May 2013 in Moore/Newcastle.

Meteorologist Alex Lamers tweeted, “I don’t recall ever seeing two such massive debris fallout signatures in close proximity before. Any radar experts remember one?”

The concern was that there may have been two EF5 tornadoes because there were two debris balls being observed on radar. Meteorologists, climatologists and weather experts all concluded it was like nothing they’ve ever seen before.

Dodental tornado stijgt tot boven de 30; schuilkelders toch open ondanks corona

In het zuiden van de Verenigde Staten zijn al ruim 30 mensen om het leven gekomen door het zware stormweer. Alleen al in Mississippi kwamen elf mensen om het leven na de doortocht van verschillende tornado’s. Ook South Carolina, Louisiana, Georgia en Arkansas zijn zwaar getroffen. Meer dan een miljoen huishoudens zit zonder stroom.

Weerdienst NOAA waarschuwde zondagmiddag voor tornado’s met windstoten tot 330 kilometer per uur. De weerdienst sprak van een ‘uitzonderlijk zeldzame gebeurtenis’. Beelden op sociale media lieten zien hoe de tornado's een spoor van vernieling hebben achtergelaten.

In South Carolina kwamen volgens televisiezender ABC zeker negen mensen om in erg hevig stormweer, in Georgia vielen acht doden, in Tennessee drie en in Arkansas één. Ook de staat Louisiana werd zwaar getroffen. Honderden huizen werden daar vernield.

Schuilen
Door de coronacrisis twijfelden diverse lokale autoriteiten of ze de openbare schuilkelders wel moesten openen voor de inwoners. In Alexander City zei burgemeester Thomas Spraggins aanvankelijk dat de deuren gesloten zouden blijven en mensen zelf een veilig heenkomen moesten zoeken. Maar uiteindelijk besloot hij toch mensen met mondkapjes en handschoenen toe te laten nadat hun temperatuur was gecheckt. In de staat Mississippi werden mensen opgeroepen om ook op de schuilplekken 2 meter afstand te bewaren.

Late-evening EF-2 tornado hits Arlington as the first significant November tornado in North Texas since 1987

A late-evening tornado touched down in Arlington, Dallas-Forth Worth Metropolitan Area on November 24, 2020, leaving a trail of damage to buildings and vehicles. The National Weather Service (NWS) said their survey team found EF-2 damage in south Arlington.

Just before 21:00 LT on November 24, a severe storm capable of producing a tornado was located near Grand Prairie, moving east at 72 km/h (45 miles per hour), according to LXAS news. The tornado warning was lifted just after 21:20 LT (03:20 UTC, November 25).

Shortly after, the Arlington Police Department said that it's assisting the Arlington Fire Department with damage across the city. "This also includes various roof collapses on some structures and damages to buildings. Working to determine extent of damages and whether or not there are any injuries."

"Pioneer Parkway is closed in both directions between Center Street and Collins Street due to debris from area apartment complexes on roadway."

NBC said it appears that one of the hardest-hit areas is just south of West Pioneer Parkway near South Cooper Street. The worst-hit were the Mirage and Waterdance Circle apartment complexes along Pioneer Parkway.

The NWS Forth Worth office said their survey team found EF-2 damage in south Arlington.

The maximum estimated winds were 185 km/h (115 mph), the survey found. The tornado had a path length of 8.1 km (5.04 miles) and maximum width of 137 m (150 yards).

It was on the ground for about 7 minutes, injuring 5 people and displacing 75 families.

The Arlington Fire Department said 3 apartment complexes collapsed, as well as 2 commercial buildings, a church, and a home. Gas leaks and downed power lines were also reported at various locations.

This year's tornado season could be more severe than usual across the USA, in part because of La Niña.

The climate pattern called La Niña – a natural cycle marked by cooler-than-average ocean water in the central Pacific Ocean – is one of the main drivers of weather around the world, especially during the late fall, winter and early spring.

El Niño is the warming of these waters, which leads to different effects on weather patterns, according to Weather.com.

AccuWeather meteorologists said that because of La Niña, severe weather and tornado activity could abruptly fire up and rival 2011, one of the most notorious severe weather seasons, when tornadoes killed more than 550 Americans.

"The temperature of the water in the central and eastern tropical Pacific during February 2021 is similar to the La Niña pattern in February 2011," AccuWeather meteorologist Paul Pastelok said.

A study in 2015 from Columbia University found that a fairly strong La Niña brings more tornadoes and hailstorms over portions of Oklahoma, Texas, Kansas and other parts of the southern USA.

La Niña concentrates hot, humid air over the southern USA, the National Oceanic and Atmospheric Administration said. The heat and humidity over the southern Plains states sets up a strong north-south temperature gradient, which in turn favors storm formation.

A study in 2017 published by the American Meteorological Society also found a link between U.S. tornado activity and La Niña.

Based on past decades, the chance for tornadoes typically increases from February into March in the South, and it is highest from April through June across the Plains, Weather.com said.

Pastelok said the mid- to lower-Mississippi Valley and the mid-Atlantic regions will have the highest risk for severe weather this spring.

Though several private teams offer seasonal tornado forecasts, including AccuWeather and Weather.com, the federal government's NOAA does not, at least yet.

"Seasonal tornado forecasts are challenging, and there's some work being done on the problem," Harold Brooks, a senior research scientist at NOAA's National Severe Storms Laboratory, told USA TODAY.

"A big value of seasonal forecasts is that it provides a venue to highlight preparation and safety information to the public. That's the biggest thing about the hurricane forecasts and is a reason we might consider making them (tornado forecasts) in NOAA," he said.

Tornado activity is forecast to be slightly above normal for the year, and the number of tornadoes is expected to reach 1,350 to 1,500 in 2021 across the USA, according to AccuWeather meteorologists. Annually, the number of tornadoes averages 1,250 to 1,400, according to U.S. government statistics.

Already this year, there have been two deadly tornadoes, according to the Storm Prediction Center: one in central Alabama on Jan. 25, which killed one person and injured at least 30, and another in North Carolina on Feb. 15, in which three people died. The North Carolina twister, which left at least 10 people injured, hit southeastern Brunswick County near Grissettown.

Last year was a below-average year for tornadoes. According to preliminary figures, there were 1,075 reports in 2020, AccuWeather said.

The number and severity of tornadoes in any given year do not appear to be linked to human-caused climate change. A report in 2016 from the National Academy of Sciences, Engineering and Medicine found that of all weather phenomena, severe storms and tornadoes are the most difficult to attribute directly to climate change.
