40 million in US South on active tornado watch – live

A tornado watch has been issued for parts of Arkansas, Louisiana and Mississippi until 7 p.m. (Central Time) on Tuesday.

It’s rare that federal forecasters warn of large tornadoes with the potential for damage over great distances, but they are doing so in Tuesday’s forecast. The Associated Press Reported on Tuesday.

The Norman, Oklahoma-based storm forecast, “Several rounds of severe thunderstorms – capable of long-lasting tornadoes with EF3+ damage potential – will be possible across the lower Mississippi Valley region and parts of the Mid-South through this afternoon.” the 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 land 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 powerful storm system moves across an area stretching from eastern Texas to Indiana and Georgia. The National Storm Prediction Center said in its statement Latest Storm Outlook Cities affected may include New Orleans; Memphis and Nashville in Tennessee; and Birmingham, Alabama.

Parts of Louisiana and Mississippi will be at highest risk of severe thunderstorms Tuesday afternoon and evening, with severe weather likely to continue through Wednesday and move into Alabama.

The Weather Channel’s hurricane expert Dr. Rick Knabb shares tips on staying safe during severe weather.

In December 2021, a powerful tornado outbreak killed dozens of people in six US states.

At the time, I wrote about the difficulty of linking these events to the climate crisis.

storm Whirlwinds are vertical air columns that form in thunderstorms and stretch to the ground. They travel with tremendous speed and destroy everything that comes in their way.

Hurricanes occur when dense, dry cold air is pushed over warm, moist air, a phenomenon scientists call atmospheric instability. As this happens, an updraft is created when warm air rises. When winds differ in speed or direction at different altitudes – a condition known as wind shear – the updraft will begin to spin.

These changes in the winds generate the necessary spin for the tornado. For particularly strong tornadoes, a change in both wind speed and direction is required.
