Intense storms spawning dozens of tornadoes tore through large swathes of the US South leaving at least two people dead, knocking out power to thousands and damaging several homes, authorities said Wednesday.

The severe weather systems that included fierce winds, heavy rain and hail threatened millions of Americans across eight states from Texas to Georgia beginning Tuesday, with tornado warnings forcing residents to seek shelter.

In Alabama, two people died before dawn Wednesday when "severe weather, most likely a tornado," hit North Montgomery County, an official there quoted the county sheriff's office as saying.

At least 36 tornadoes in all were reported touching down in the Gulf coast states of Alabama, Louisiana and Mississippi, while dangerous wind and hail were also reported in Texas, Arkansas, Tennessee, Kentucky and Georgia, according to the National Weather Service.

Tornadoes damaged roads, downed trees and power lines, and blew roofs off houses, NWS said.

As of 10:00 am (1500 GMT) Wednesday some 27,000 customers in Alabama and 12,000 in Tennessee were without power, monitoring site poweroutage.us reported.

Tornadoes are a frequent and often devastating weather phenomenon in the United States, with the Great Plains states of Kansas, Oklahoma and Texas the hardest hit.

Twisters that strike overnight are particularly dangerous — and often more deadly — because they are difficult to see in the dark.

In early November a series of tornadoes battered Oklahoma, Texas and Arkansas, leaving one person dead.

In December last year, dozens of devastating tornadoes ripped through five states at night, leaving at least 79 people dead in Kentucky — with fatalities also recorded in Tennessee, Arkansas, Missouri and Illinois.

Two dead, dozens missing as landslide wipes out Brazil highway
Rio De Janeiro (AFP) Nov 30, 2022 –

At least two people were killed and dozens more are missing after a landslide ripped across a section of highway in southern Brazil, sweeping some 20 cars and trucks along with it, authorities said Wednesday.

The torrent of mud came rushing down a steep hillside Monday after days of heavy rain in the state of Parana, hitting highway BR 367, officials said.

"It's hard to know the exact number of victims. A vehicle could have one to five people inside. We're working with an estimate of 30 to 50 people missing," local emergency response chief Manoel Vasco told a news conference.

Aerial images released by the emergency services showed a massive smear of mud that swept away everything in its path — including a chunk of highway and the vehicles on it.

Rescue workers said the bad weather and remote location were complicating the search effort.

They are using drones with heat-detecting cameras in hopes of finding survivors.

"Fifty-four firefighters have been working non-stop for more than 35 hours," the Parana state security authority said in a statement later Wednesday, noting as well concerns over further landslides.

Two bodies have been found so far, and six survivors have been located, including the mayor of the coastal town of Guaratuba, the nearest city.

"It was horrible. The mountain just fell on top of us. It swept away every last car. We're only alive by the grace of God," the mayor, Roberto Justus, said in a video posted on social media.

Brazil is frequently hit by deadly landslides.

The national weather service INMET has issued heavy rain warnings for multiple states.

At least one other person died Wednesday after a section of road was washed out, sweeping away the victim's car, in the northeastern state of Segipe, Brazilian media reported.

In February, more than 200 people were killed in a series of landslides in the picturesque southeastern tourist town of Petropolis.
