At least 25 people are dead in Mississippi and one in Alabama following a terrifying Friday night in which large, destructive tornadoes tore across the state.
The twisters formed from the same destructive storm system that barged into California’s Bay Area on Tuesday and produced deadly flooding in both the Desert Southwest and the nation’s midsection.
The twisters’ terrible toll can be linked to their utter ferocity, the vulnerability of the region they struck and for sweeping through at night, when it was difficult to see them coming.
How the tornadoes were unleashed

The rotating thunderstorm or supercell that spawned the deadly tornadoes swept across the entirety of Mississippi and continued through northern Alabama — an exceptionally long path for a single storm. Supercells contain rotating updrafts fueled by warm, unstable air near the ground and are twisted by changing winds with altitude.
The National Weather Service in Jackson, Miss., first issued a tornado warning for the storm as it was exiting Louisiana and entering Mississippi around 7:40 p.m.
At 7:58 p.m., the agency cautioned that “a large and extremely dangerous tornado” was seven miles west of Rolling Fork, a town of about 2,000 people about 60 miles northwest of Jackson. By 8:03 p.m., the storm arrived. “This is a PARTICULARLY DANGEROUS SITUATION. TAKE COVER NOW!” the National Weather Service warned. Rolling Fork was among one of several towns that were especially hard hit.
The wedge-shaped funnel was probably on the ground for the next 90 minutes, covering 80 miles as it barreled across west-central Mississippi at high speeds. The Weather Service was compelled to declare multiple tornado emergencies, the most dire alert for twisters, as it carved a path through Anguilla, Louise, Midnight, Silver City, Tchula and Winona — all small towns or communities less than 90 miles northwest and north of Jackson.
Along this path, the tornado lofted debris 30,000 feet high, said Samuel Emmerson, a member of the radar research group at the University of Oklahoma, describing it on Twitter as an “extremely high-caliber” tornado.

Shortly after passing Winona, around 9:32 p.m., the tornado may have weakened or lifted for a time as the storm raced across northeast Mississippi.
However, it appeared to re-form and strengthen around 10:50 p.m., when the Weather Service office in Memphis declared yet another tornado emergency for the town of Amory, Miss., and nearby Smithville, about 150 miles northeast of Jackson, near the border with Alabama.
When radar displayed an unmistakable signature of debris immediately west of Amory, confirmation of the destructive twister, broadcast meteorologist Matt Laubhan for television station WTVA could not contain his emotion.
“Dear Jesus, please help them,” he pleaded.
I don't think I've *ever* heard a meteorologist say a little prayer or "oh man" on air. #mswx— Eddie Sigala 💉👌🏼🥰🇺🇦🇺🇸 (@eduardokenya) March 25, 2023

The storm crossed into northwest Alabama shortly after 11 p.m. and continued producing tornadoes until it reached the northeast part of the state around 12:45 a.m.
The Weather Service received at least 10 reports of tornadoes in northern Alabama from this storm. Around Hartselle, which is about 30 miles southwest of Huntsville, one man was killed and the agency logged reports of damage to homes, people trapped and a tractor-trailer overturned.
Severe storm affected 8 southern states and it’s not over
The storm that swept across Mississippi and northern Alabama was one of many that raged through the South on Friday into Saturday.
The Weather Service logged more than 170 reports of severe weather from Louisiana to western North Carolina, including more than 80 instances of violent straight line winds that toppled trees and power lines and damaged homes. Tens of thousands lost power.
The Weather Service reported one person was injured near Nashville when a tree fell on a house.
Severe storms continued to scatter around both the Southeast and the Ohio Valley on Saturday, producing more than 100 reports of damaging winds and large hail. A tornado was reported in southeast Alabama — producing areas of damage.
As the storm front stalls across the South on Sunday, the risk of severe weather is predicted to increase again between Louisiana and Georgia. “A few strong tornadoes and very large hail should accompany the most intense storms, particularly from central Louisiana across central to southern portions of Mississippi and Alabama,” the National Weather Storm Prediction Center wrote. A pair of damaging tornadoes touched down in Georgia on Sunday morning.

A deadly legacy
The larger storm system that spawned Friday’s tornadoes has a lethal history. When it slammed into California on Tuesday, at least five people were killed by trees toppled by winds up to 80 mph in the Bay Area. The same storm spawned the strongest tornado to hit the Los Angeles metro area since 1983.
As the storm exited California on its way toward the central states, it triggered severe flooding in central Arizona, where at least three people died after their vehicles were swept away by floodwaters, the Associated Press reported.
The storm unloaded more heavy rain that spurred flooding over an extensive swath of the central and eastern United States — stretching from eastern Oklahoma into northern West Virginia. The AP reported a car was swept away by floodwaters in southwest Missouri, killing two passengers.
What caused the storm
When it first hit California, the storm was a powerhouse, intensifying rapidly as it made landfall in the Bay Area, meeting the meteorological criteria for a “bomb cyclone” because of its rapid drop in pressure. The lower the pressure, the stronger the storm.
Sweeping across the country, the storm has been energized by the roaring high altitude winds of the jet stream — powered by the strong temperature contrasts of early spring.
Ahead of the storm, temperatures soared, setting numerous records across the South and Southeast, rising into the 80s. Tupelo, Miss., tied a record high of 85 degrees Friday.
This warm and humid air helped provide the fuel for Friday’s storms. Abnormally high sea surface temperatures over the Gulf of Mexico, drawn northward ahead of the storm, intensified this warm, moist air mass.
As the warm winds from the south fueled the storms at ground level, the westerly winds of the jet stream were crashing south, generating extreme amounts of wind shear. This shear — or changing wind direction with altitude — created the spin in the atmosphere necessary for the violent tornadoes.
The links between human-caused climate change and tornadoes are complex, but researchers agree higher temperatures provide more energy for storms — especially in winter and early spring when warmth is ordinarily limited.
Why the tornadoes were so deadly

In a preliminary assessment of the tornado that struck Rolling Fork and Silver City, the Weather Service reported it produced EF4 damage on the 0-to-5 Enhanced Fujita intensity scale, meaning it had winds of at least 166 mph. Tornadoes this strong are difficult to survive unless in a very well-built building or underground.
The Southeast has a disproportionate number of mobile homes, which cannot withstand strong tornadoes, compared with other parts of the country, which makes it particularly vulnerable.
“[T]he Southeast’s mobile home residents are one of the most socioeconomically and demographically marginalized populations in the United States and are more susceptible to tornado impact and death,” tornado researchers Stephen M. Strader and Walker S. Ashley wrote in a 2018 study.
The tornadoes were also particularly dangerous because they occurred at night. When it’s dark, the visual cues that sometimes prompt people to take action are absent, and some are asleep. A 2022 study by Strader, Ashley and others found nighttime tornadoes are nearly twice as deadly as daytime events.
Deadly tornadoes outbreak in Mississippi and Alabama
The latest: As a violent tornado neared Rolling Fork, some residents say they didn’t hear any sirens. Tornadoes are common in Mississippi — but not often this deadly — and mobile homes in Rolling Fork were most vulnerable to damage. On Friday, devastating tornadoes in Mississippi and Alabama killed at least 26 people.
Why was the Mississippi tornado’s size rare? It caused at least 25 deaths in the state along a path of 59.4 miles, according to the National Weather Service. Photos of damage in Mississippi show areas reduced to piles of wreckage. Here’s why Mississippi’s tornadoes were so deadly and the dangers of storm chasing in the dark.
Are there any relief efforts? For some Rolling Fork residents, recovery from the severe Mississippi tornado damage is uncertain. Here’s how to help those impacted by the tornadoes.
