The National Weather Service in Shreveport, Louisiana reported early Wednesday morning that part of what fuelled Tuesday’s severe weather can be attributed to the warmer than average temperatures experienced across the region.

In Shreveport, located in the northwest part of the state, the city recorded a high of 81 degrees Fahrenheit, while over in Texas, the city of Tyler recorded a high of 82 degrees.

Both broke records of 80 degrees, which had been previously set in 1949.

What is a derecho?

01:00 , Louise Boyle

A derecho is a wind storm that is long-lived, severe and takes place across a wide area.

Derecho-producing storm systems can also contain tornadoes, but they consist mostly of (and are defined by) damaging non-tornadic wind, according to the National Weather Service.

“Sometimes, an intense derecho can result in hundreds of severe wind and damage reports spread along a swath covering multiple states, with deaths, injuries, and many millions of dollars in losses,” the federal agency says.

In August 2020, a powerful derecho struck the Midwest and caused more than $11billion in damages across eastern Nebraska, Iowa, Illinois, Wisconsin, and Indiana.

Winds reached 126mph (203 km/h) in Iowa and sustained winds held at around 70mph through the affected area.

There were blackouts across the region including in Cedar Rapids, Iowa which was left without power for weeks in some parts. There was also severe damage to crop staples like corn and soybeans in the agricultural stronghold.

What is a ‘particularly dangerous situation’ in relation to a tornado watch?

00:14 , Louise Boyle

According to the National Weather Service’s Storm Prediction Center, the “Particularly Dangerous Situation” wording is used in Tornado Watches for rare situations when long-lived intense tornadoes are likely.

The wording may also accompany Severe Thunderstorm Watches for widespread significant severe events, usually produced by exceptionally intense derechos.

PDS watches are issued, when in the opinion of the forecaster, the likelihood of significant events is boosted by very volatile atmospheric conditions.

What is the difference between a tornado watch and a tornado warning?

Tuesday 29 November 2022 23:30 , Louise Boyle

The National Weather Service differentiates between a tornado watch and tornado warning.

A Tornado Watch tells residents to be prepared that tornadoes are possible, in and near the watch area. People should go over their emergency plans, check supplies and safe rooms. The aim is to be ready to act quickly. Watches are issued by the Storm Prediction Center for counties where tornadoes may occur. The watch area is typically large, covering numerous counties or even states.

A Tornado Warning means take action because a twister has been sighted or indicated by weather radar. There is imminent danger to life and property. People should move to an interior room on the lowest floor of a well-constructed house or building, avoiding windows. If in a mobile home, a vehicle, or outdoors, move to the closest substantial shelter and protect yourself from flying debris. Warnings typically encompass a much smaller area (around the size of a city or small county) that may be impacted by a tornado.

Tuesday 29 November 2022 22:45 , Louise Boyle

What role the climate crisis is playing in the severity and frequency of tornadoes is still being heavily debated in the scientific community.

However recent research has suggested that the rising global temperature may be shifting the paths of tornadoes in the United States.

What do you do if caught in your vehicle during a tornado?

Tuesday 29 November 2022 20:59 , Louise Boyle

Being in a vehicle during a tornado is not safe, the National Weather Service warns.

The best move is to drive to the closest, well-constructed shelter. If this isn’t possible, then either get down in your car and cover your head, or abandon your car and seek shelter in a low lying area such as a ditch or ravine, the NWS advises.

The Weather Channel also has this helpful video.

What makes a good tornado shelter?

Tuesday 29 November 2022 20:46 , Louise Boyle

The National Weather Service shared tips on Tuesday of how to take cover during tornadoes.

The best options are an above or below-ground tornado storm shelter that is compliant with the standards of the Federal Emergency Management Agency (FEMA). A specifically-designed FEMA safe room is also among the best options.

Good options are an interior room of a well-constructed house or building, or a basement.

Bad options are large, open rooms like gymansiums or manufactured housing.

The worst options are mobile homes, vehicles or underneath a highway overpass.

Rare warnings

Tuesday 29 November 2022 19:12 , Louise Boyle

It’s rare that federal forecasters warn of major tornadoes with the potential for carving damages across long distances, but they are doing so in Tuesday’s forecasts, the Associated Press reported on Tuesday.

“Multiple rounds of severe thunderstorms -- some capable of long-tracked tornadoes with EF3+ damage potential -- will be possible this afternoon into tonight over parts of the lower Mississippi Valley region and Mid-South,” the Norman, Oklahoma-based Storm Prediction Center said.

Tornadoes with an EF3 rating on the Enhanced Fujita tornado scale can produce wind gusts of up to 165 mph (266 kph).

Forecasters warned of the potential for strong tornadoes that could stay on the ground for long distances in parts of the South, as well as flooding rains and hail the size of tennis balls.

More than 25 million people will be at risk as Tuesday’s potent storm system moves across a region stretching from east Texas to Indiana and Georgia. The national Storm Prediction Center said in its latest storm outlook that affected cities could include New Orleans; Memphis and Nashville in Tennessee; and Birmingham, Alabama.

Parts of Louisiana and Mississippi will be at the highest risk for strong storms Tuesday afternoon and evening, with the possibility of severe weather continuing into Wednesday and moving into Alabama.

What is a tornado?

Tuesday 29 November 2022 16:39 , Sam Webb

Tornadoes are whirling, vertical air columns that form from thunderstorms and stretch to the ground. They travel with ferocious speed and lay waste to everything in their path.

Thunderstorms occur when denser, drier cold air is pushed over warmer, humid air, conditions scientists call atmospheric instability. As that happens, an updraft is created when the warm air rises. When winds vary in speed or direction at different altitudes — a condition known as wind shear — the updraft will start to spin.

These changes in winds produce the spin necessary for a tornado. For especially strong tornadoes, changes are needed in both the wind’s speed and direction.

Still some risk tomorrow

Tuesday 29 November 2022 16:24 , Sam Webb

According to weather.com, the potential for severe weather will decrease on Wednesday. However, some parts of the Southeast could see one to two inches of rain and flash flooding is possible in areas where too much rain falls too quickly.

Meteorologist explains threat levels

Tuesday 29 November 2022 16:00 , Sam Webb

Meteorologist Craig Ceecee has outlined what the storm categories mean:

He added: “If you can’t get to your safe place from home, or up and out, in 5 minutes - especially if in a mobile home or weaker structure - you should spend the time under #tornado threat tomorrow somewhere else (with family/friends, at work or at a shelter).”

Safety plan is ‘imperative'

Tuesday 29 November 2022 15:47 , Sam Webb

Meteorologist for @WCBINEWS Jackson Chastain tweeted: “This is what we are up against. A Tornado Watch is likely by early this afternoon.

“The window is large, as is the potential for several long-track tornadoes. It is imperative that you have a safety plan going into this evening.”

Take picture for insurance. residents urged

Tuesday 29 November 2022 15:43 , Sam Webb

The Mississippi Emergency Management Agency is urging homeowners to photograph their property before the storm hits for insurance purposes. It tweeted: “We encourage Mississippians to take photos of their home BEFORE the storms. These photos can be used for insurance purposes and/or possible assistance if your home is damaged in the storm.”

‘Make decisions quickly'

Tuesday 29 November 2022 15:40 , Sam Webb

Bill Bunting, chief of forecast operations at the Storm Prediction Center, told CNN Weather, said: “Another challenge with nighttime tornadoes, especially in the fall and winter, is that storms typically move very quickly, at times 50 or 60 mph.

“This means that you must make decisions quickly and take shelter based on information contained in the severe thunderstorm or tornado warning, and not wait until the storm arrives,” he added.

Hail and strong wind also a threat

Tuesday 29 November 2022 15:39 , Sam Webb

A total of three million people across much of Mississippi and parts of western Alabama, southwestern Tennessee, eastern Arkansas, northern Louisiana, and a small part of eastern Texas are at risk of hail, strong wind, and tornadoes.
