Large tornado hits New Orleans, causing extensive damage, Louisiana

A destructive wedge tornado ripped through parts of New Orleans, Louisiana Tuesday night, March 22, 2022, causing extensive damage, killing at least one person, and leaving several others injured. This raised the number of fatalities related to the severe weather outbreak affecting the Deep South over the past few days to 2. Severe storms with the potential for damaging winds and brief tornadoes can be expected across the Southeast today. Strong to severe storms will be possible into the Ohio Valley and southern Mid-Atlantic. Some storms may produce locally heavy rain and flash flooding.

The tornado touched down at approximately 19:35 CDT in a New Orleans suburb and then moved east across the Mississippi River into the Lower 9th Ward of New Orleans and parts of St. Bernard Parish before moving northeast. It was on the ground for about 15 minutes.

St. Bernard Parish appears to have taken the brunt of the storm. This is where the fatality and injuries were reported but officials are yet to give details.1

The New Orleans Fire Department has requested a major EMS response following the tornado. The damage was said to be significant in parts of Lower Ninth Ward and nearby suburb Arabi.2

A Fox 8 New Orleans report from the area shows immense structural damage, overturned cars, and downed power lines.

Major damage after tornadoes rip through parts of Oklahoma and Texas, U.S.

Major damage was reported in parts of Texas and Oklahoma after a series of tornadoes ripped through the region on Wednesday, May 4, 2022. On Thursday, severe thunderstorms are expected from eastern Texas into the mid-Mississippi Valley. Storms will shift over the lower Mississippi into the Tennessee Valleys on Friday, then Saturday into Monday from the central Plains into the Midwest.

Extensive structural damage was reported in the town of Lockett, TX, located about 80 km (50 miles) NW of Wichita Falls. In a phone call with The Weather Channel, a sheriff’s department employee in Wilbarger County said deputies were on the scene as of about 21:40 CDT.1

Another tornado hit Dickens County in the Texas Panhandle, about 80 km (50 miles) east of Lubbock. The tornado tracked east to south of Paducah.

Tornadoes also hit Seminole, OK tearing apart buildings, downing trees and powerlines, and littering streets with debris. Some 12 000 power outages were reported in Seminole County.2

The Academy of Seminole, a public charter school, was among the buildings damaged after taking a direct hit by the tornado.

“We will be accessing the damage over the next few days. Please do not come to the school: it is extremely dangerous. Everyone who was at the school is safe,” school officials said.

Ten minste 20 tornado's richten schade aan in zuiden VS

In de staten Mississippi, Louisiana en Alabama in het zuiden van de Verenigde Staten zijn woensdag getroffen door minstens twintig tornado's, zo laat de National Weather Service (NWS) weten. De tornado's bliezen daken van huizen, beschadigden wegen en zorgden voor stroomuitval en omgevallen bomen.

Eén tornado die door Alabama trok werd door de NWS "levensbedreigend" genoemd. Volgens de Amerikaanse weerdienst zijn tornado's 's nachts extreem moeilijk te zien en te herkennen. "Wacht niet om de tornado te zien of te horen. ZOEK NU DEKKING!", aldus de NWS in een waarschuwing. Voor delen van Mississippi en Alabama gold tot 06.00 uur lokale tijd een tornadowaarschuwing. In laatstgenoemde staat werden ook hagelstenen ter grootte van een baseball voorspeld.

Begin deze maand trok een reeks krachtige tornado's nog door Oklahoma, Texas en Arkansas, waarbij één dode viel. Vanwege de ligging lopen Texas, Oklahoma en Arkansas doorgaans het meeste risico om getroffen te worden door tornado's, die vaak en soms verwoestend toeslaan in de VS. In december vorig jaar kwamen minstens 69 mensen om toen tientallen tornado's door vijf Amerikaanse staten trokken.

One dead, one missing in tornado
CADDO PARISH, La. (KSLA) — A child is dead, his mother is missing, another person is hurt and multiple homes are destroyed in the wake of tornadic storms that blew through the area Tuesday, Dec. 13.

“It’s really a sad, sad situation. And it’s one of the most unusual things I have ever seen,” Caddo Sheriff Steve Prator said, noting that the child’s body was found about a half mile from where the house used to be.

Authorities will be searching throughout the night and Wednesday for the mother, Prator added.

Manufactured/mobile homes were among dwellings destroyed on Pecan Road just northwest of Four Forks near Fullilove Cemetery in Caddo Parish, a storm chaser told the National Weather Service office in Shreveport. A forest was mowed down in that area as well.

Caddo sheriff’s deputies were dispatched to the area of Lareta Street in Keithville’s Pecan Farms area after a tornado touched down there. The Sheriff’s Office reports that several structures were damaged and electrical lines and trees were knocked down.

The few houses that were in one area were destroyed, the sheriff said.

Early on, one woman was taken to a hospital for treatment of unknown injuries, and two people were missing, authorities reported. Caddo sheriff’s deputies, K-9 teams, firemen and volunteers searched through debris and the area for the missing people.

Then about 11:30 p.m., Prator confirmed that the child’s body had been found.

Other Caddo deputies continue to check house to house on the welfare of other residents there.

The storms spawned multiple tornado warnings, with four simultaneously at one point, in the ArkLaTex.

Zeker zes doden door tornado in Amerikaanse staat Alabama

In de Amerikaanse staat Alabama zijn zeker zes mensen om het leven gekomen door een tornado. Minstens twaalf gewonden zijn naar het ziekenhuis gebracht. Hoe zij eraan toe zijn, is niet bekend. In Georgia overleed een automobilist toen een boom omwaaide en op de auto van het slachtoffer terechtkwam.

Er wordt nog gezocht naar mensen die mogelijk onder omgevallen bomen terecht zijn gekomen. "Sommige huizen die volledig zijn verwoest zijn nog niet doorzocht", aldus een lokale functionaris. "Er wordt nog in het puin gezocht."

De doden in Alabama vielen in Old Kingston, een gemeenschap in Autauga County. Door het noodweer raakten enkele tientallen woonwagens en huizen beschadigd. In de nabijgelegen stad Selma is een avondklok van kracht.

In het hele land waren er donderdagavond meldingen van 33 tornado's bij de National Weather Service. Vooral het zuiden is zwaar getroffen. In de staten Georgia, South Carolina en North Carolina zijn nog steeds tornado-waarschuwingen van kracht. Tienduizenden mensen in de staten Georgia, Mississippi en Alabama zitten zonder stroom.

...Synopsis...
A deep mid/upper-level trough is forecast to become negatively
tilted as it traverses the southern Plains on Thursday. A surface
low is expected to steadily deepen somewhere near the Red River
during the day, with more rapid deepening expected Thursday night as
the cyclone moves northeastward toward the Ozarks. Seasonably rich
low-level moisture will be in place across the warm sector of the
developing cyclone through the period.

...Southern Plains into the ArkLaTex/ArkLaMiss region and parts of
the Southeast...
A regional severe thunderstorm outbreak still appears possible from
the southern Plains into the ArkLaTex/ArkLaMiss regions Thursday
into Thursday night. All severe hazards will be possible, including
the potential for widespread damaging winds and strong tornadoes,
though uncertainty remains regarding the timing and evolution of
severe thunderstorm development Thursday afternoon/evening.

Relatively steep midlevel lapse rates will support moderate buoyancy
across the moist warm sector, while deep-layer shear will steadily
increase through the day as a 80-100 kt midlevel jet approaches from
the west. The coverage and timing of convection remains somewhat
uncertain, with stronger large-scale ascent expected to remain west
of the warm sector for much of the day. Discrete supercell
development will be possible near the ArkLaTex vicinity by late
afternoon into the evening, as a low-level jet becomes increasingly
intense near/after 00Z. Any sustained supercells would pose a strong
tornado risk as low-level shear increases with time, along with the
potential for hail. More widespread development is expected along
the surging cold front across parts of north/central TX by evening.
The frontal convection will spread quickly eastward, posing a threat
of potentially widespread damaging wind and a continued tornado
threat.

Some portion of this area may eventually require a categorical
upgrade, if confidence increases regarding a corridor of
strong-tornado and/or significant-wind potential.

The eastward-surging frontal convection may tend to weaken with time
by early Friday morning across eastern MS/western AL, as the primary
mid/upper-level system begins to move northeastward away from the
region, though very strong deep-layer flow/shear will continue to
support a threat of damaging wind and line-embedded tornadoes
through the end of the period.

Over 65 million people in central US at risk of severe weather outbreak
AccuWeather meteorologists say explosive thunderstorm development will occur on Friday, and the storms will threaten a large swath of the country that includes cities such as Chicago, St. Louis, Little Rock and Indianapolis.

At least 15 states will be at risk of an outbreak of violent thunderstorms that will unleash everything from damaging winds to tornadoes on Friday, AccuWeather meteorologists warn. The area highlighted by forecasters is a massive swath of the country that extends from Texas to Alabama in the South to areas farther north such as Wisconsin and Michigan.

The AccuWeather forecast team raised Friday’s risk of severe weather from moderate to a high level prior to the middle of the week, a sign of growing concern for the potential damage the storms could cause.

"While all modes of severe weather are likely during Friday's outbreak, there is a likelihood of widespread damaging winds from the storm with at least several tornadoes likely to be on the ground," AccuWeather Chief On-Air Meteorologist Bernie Rayno said.

The area forecasters say is under a high risk extends from parts of eastern Iowa and southwestern Wisconsin to portions of northern Arkansas and western Tennessee.

According to the National Weather Service's Storm Prediction Center, more than 65 million Americans are at risk of some form of severe weather on Friday.

Major cities that are likely to be hit with severe thunderstorms capable of generating a tornado include St. Louis, Chicago, Indianapolis, Little Rock, Arkansas, and Memphis, Tennessee. As the storms approach and push through the major metro areas, Federal Aviation Administration officials will likely issue ground stop orders on all flights.

In addition to the likelihood of damaging wind and the possibility of a tornado in the strongest storms, there is the potential for large hail, frequent lightning strikes and brief torrential downpours as well.

"The severe storms will approach and swing through the Chicago metro area sometime from 5-10 p.m. on Friday, which is an extremely busy time for airlines and vehicle traffic as people begin their weekend journeys and end their weekday activities," AccuWeather Meteorologist Brandon Buckingham said.

The storms will likely push through St. Louis on Friday afternoon but may not hit Memphis and Indianapolis until well after dark.

A potent storm from the Pacific will re-energize after it crosses the Rockies on Thursday. The first few severe thunderstorms are likely to erupt in portions of Nebraska and Kansas late in the day and linger into Thursday night. These first storms have the potential to bring the full spectrum of severe weather but are likely to be isolated in nature.
