There have been a number of weather-related deaths in Oklahoma since storms and flooding began on Friday, including a firefighter who died during a water rescue, and a 48-year-old woman who was killed after a tornado struck her home.

Nearly two years ago, a powerful tornado – the widest on record – struck the rural outskirts of Oklahoma City. Fortunately it missed heavily populated areas, but the ensuing flash flood killed 13 people in Oklahoma City, including nine Guatemalan immigrants.

Popular Mechanics recently talked with KFOR's Emily Sutton about bad movie science, the power of nature, and staring down an EF5 tornado.

Tornadoes in western Oklahoma damaged homes, brought down power lines and otherwise caused havoc Saturday evening, but no casualties have been reported.

Two years ago, one of the worst tornadoes on record hit the town of Moore, Okla. And you might say to yourself, well, doesn't this always happen there? It's called Tornado Alley for a reason.

And that's pretty much how the residents of Moore think about tornadoes. They're just part of life, and you take your chances. But that kind of thinking was part of the problem on May 20, 2013. The storm that came through that day was different. It was horrific.

A series of tornadoes in North Texas over the weekend have left at least one person dead and others missing. Meanwhile, in South Carolina, a weakening Tropical Storm Ana made landfall early this morning near Myrtle Beach, S.C.

One of the tornadoes that hit Saturday destroyed homes in a rural area south of Cisco, a town about 100 miles west of Fort Worth, Eastland County, Judge Rex Fields was quoted by The Associated Press as saying.

More than a dozen tornadoes ripped through Oklahoma on Wednesday, destroying homes and injuring 12 people.

The Oklahoman reports that the damage is widespread and that the thunderstorms that spawned the twisters also brought lots of rain that could lead to record flooding.

The paper reports:

Last week, as a big storm bore down on Rockford, Ill., students in a Purdue University classroom prepared to track its effects using Twitter.

Using software jointly developed by Purdue, the Department of Homeland Security and the National Weather Service, they huddled around laptops to analyze a tiny sample of the tweets from the storm's immediate vicinity. They were looking for keywords like "damage" or "tornado" and for pictures of funnel clouds.

In the wake of last year’s devastating tornadoes, millions of dollars in donations went to The United Way of Central Oklahoma. The non-profit organization also agreed to administer Governor Mary Fallin’s Oklahoma Strong tornado relief campaign. Together, the funds raised a total of $20 million. 

One week after the tornado hit the city of Moore in May of 2013, country singer Blake Shelton showed up to host a benefit concert called Healing in the Heartland.

This March, Moore, Oklahoma became the first city in the nation to adopt a tornado-specific building code. City officials wanted homes to be able to withstand an EF-2 or EF-3 tornado.

But six months after the new regulations took effect, it turns out not all new homes built in the tornado’s path will have these upgrades.

Last week, on a block near Moore’s rebuilt Plaza Towers Elementary School, city official Shane Speegle walked through one house that had just been framed to check the progress.
