Tornadoes cause damage in Oklahoma; storms rock central US
Source: AP
COWETA, Okla. (AP) — Several reported tornadoes ripped through Oklahoma late Sunday into early Monday morning, causing damage but no immediate word of deaths or injuries.

The severe weather system also brought heavy rain, lightning and wind to parts of Arkansas, Kansas, Missouri and Texas.

Tornado warnings and reports of damage popped up across Oklahoma beginning Sunday afternoon. An exact number of tornadoes that touched down was not yet available as of early Monday.

A possible tornado struck the Tulsa suburb of Coweta late Sunday causing significant damage to a high school, homes and a gas station, news outlets reported.

With About Three Months Remaining, 2021 Has Already Seen the Second-most Billion-dollar Weather Disasters
by Ignacio Calderon
October 20, 2021

https://investigatemidwest.org/2021/10/ ... disasters/

Introduction:
(Investigate Midwest) Last year saw a record number of what the National Oceanic and Atmospheric Administration defines as “billion-dollar events” — storms, droughts and wildfires that cause at least a billion dollars in damages.

This year has seen the second-most, and there’s still about three months to go in the year.

Through Oct. 8, NOAA has counted 18 billion-dollar weather events. In 2020, it counted 22, the most since it started tracking in 1980.

Over the decades, the events have become more frequent and intense, with climate change playing a role in the disasters, according to the agency.
Since 1980, more than 300 events have caused more than $2 trillion in damages. About a third of that has happened in the past five years.

Atmospheric River Storms Can Drive Costly Flooding – and Climate Change is Making Them Stronger
by Dr. Tom Corringham

https://theconversation.com/atmospheric ... ger-128902

Introduction:
(The Conversation) Ask people to name the world’s largest river, and most will probably guess that it’s the Amazon, the Nile or the Mississippi. In fact, some of Earth’s largest rivers are in the sky – and they can produce powerful storms, like the ones now drenching northern California.

Atmospheric rivers are long, narrow bands of moisture in the atmosphere that extend from the tropics to higher latitudes. These rivers in the sky can transport 15 times the volume of the Mississippi River.

When that moisture reaches the coast and moves inland, it rises over the mountains, generating rain and snowfall. Many fire-weary westerners welcome these deluges, but atmospheric rivers can trigger other disasters, such as extreme flooding and debris flows.

In the past 20 years, as observation networks have improved, scientists have learned more about these important weather phenomena. Atmospheric rivers occur globally, affecting the west coasts of the world’s major land masses, including Portugal, Western Europe, Chile and South Africa. So-called “Pineapple Express” storms that carry moisture from Hawaii to the U.S. West Coast are just one of their many flavors.

My research combines economics and atmospheric science to measure damage from severe weather events. Recently I led a team of researchers from Scripps Institution of Oceanography and the Army Corps of Engineers in the first systematic analysis of damages from atmospheric rivers due to extreme flooding. We found that while many of these events are benign, the largest of them cause most of the flooding damage in the western U.S. And atmospheric rivers are predicted to grow longer, wetter and wider in a warming climate.

A West Coast storm breaks records as another storm threatens 70 million Americans in the eastern US
Source: CNN
(CNN)After the West Coast got walloped by record-setting rainfall and dangerous mudslides -- with more heavy rain in store today -- 70 million Americans in the eastern US are now also at risk for severe weather.

The threat zone Monday stretches from the southern Appalachians to New York City, according to the National Weather Service's Storm Prediction Center.

Damaging winds will be the main threat, with some isolated threats of large hail or tornadoes.

Flash flooding is another concern. From Massachusetts to New Jersey, flash flood watches will be in effect from Monday evening through Tuesday afternoon.

I am not sure that heavy rains over a rain forest environment quite qualifies as extreme weather. Still...

Heavy Rains Trigger Flooding and Evacuations in Pacific Northwest
by Rebecca Falconer
Novemberm16, 2021

https://www.axios.com/pacific-northwest ... 4aaae.html

Introduction:
(Axios) An "atmospheric river event" was bringing heavy rainfall, flooding and powerful winds to parts of the Pacific Northwest overnight, per the National Weather Service.

Why it matters: The NWS warned the tail end of the atmospheric river, packing large amounts of moisture, which has been dumping heavy rains over the northwestern U.S. and British Columbia in Canada over the past several weeks "is coming with one last strong push."
  • Tens of thousands of people were without power overnight and at least one person was reported missing, as the extreme storm system struck areas that were enveloped by wildfire smoke and extremely dry conditions this past summer.
Of note: Washington state has been particularly badly hit by heavy rains and flooding — prompting the closure of all schools in the Bellingham, Washington, district and in districts nearby, as a mudslide temporarily shut part of Interstate 5 through Bellingham Monday, AP notes.

Choppers rescue travelers on Canada highway after mudslides
Source: AP

VANCOUVER, British Columbia (AP) — Nearly 300 people trapped overnight in their vehicles by mudslides on a highway in British Columbia were being flown to safety by helicopters Monday while authorities sought to determine if anyone was swept up in the flow of debris set off by torrential rain.

A yellow Cormorant chopper dropped people off near the community center in the town of Agassiz before taking off for another rescue trip.

“Trapped between two slides are approximately 275 additional people, including 50 children, who were advised to shelter in place overnight as debris was unstable and unsafe to cross,” the City of Vancouver and Canada Task Force 1 said in a joint release.

Multiple highways in British Columbia were closed due to the downpour.

^^^ I guess if you are in the middle of such an event, and it causes something other than a routine disruption in your life, then it qualifies as "extreme weather."

Rare November tornadoes strike Long Island and Connecticut
Source: Washington Post

Subhead: A record number of tornado warnings have been issued since Oct. 1, with offshore waters near record highs

Today at 11:58 a.m. EST

Multiple tornadoes struck several Northeast states on Saturday in an unprecedented November outbreak, snapping trees and leaving behind pockets of structural damage to homes and businesses.

The mini-swarm of tornadoes occurred as an intense, tightly wound impulse swept across the region, drawing energy from near record-warm Atlantic Ocean waters. A strong cold front accompanying the disturbance incited a line of powerful thunderstorms, some of which began to rotate as they slid through Long Island and into southern New England.

Radar imagery showed numerous instances of debris lofted amid this rotation, prompting the National Weather Service to issue a total of 12 tornado warnings across New York, Connecticut, Rhode Island and Massachusetts.

At one point, two simultaneous tornadoes were probably ongoing near Islip in Long Island. The Weather Service office in New York City is conducting damage surveys near Mastic and Shirley on Sunday to determine whether and where tornadoes touched down and to assign damage ratings. In Shirley, a shopping center suffered heavy damage from the storms.

Jesus. This may be the largest December tornado outbreak ever.

Reports multiple towns hit, and some of the strongest tornado gusts ever captured by radar in one tornado along the MO/TN border.
