Inside a Florida lab testing how well equipment can withstand lightning strikes
About 40 million lightning strikes hit the ground in the U.S. each year, according to the Centers for Disease Control and Prevention.
While lightning lasts for less than a second and is only about as thick as a broomstick, it burns hotter than the surface of the sun. Florida is the lightning capital of the U.S., the CDC reports.
"So it's a challenge that we have to deal with every single day," said Jack Eble, spokesperson for Florida Power and Light.
Inside a lab in Florida, the electric company creates its own bolts.
Behind glass, wrapped in a shock-resistant faraday cage and wearing protective goggles, a CBS News crew watched as operator Wiberto Flores tested how many volts three generators could send into a power insulator and still work.
"We just put almost 500,000 volts. Three times the rate of the actual insulator," Flores said as he tested how well equipment can withstand the bolts as they become more common due to climate change.
Over the past 50 years, Florida has recorded more than 2,000 lightning injuries, the CDC says.
"We've seen a lot of things that mother nature has provided FPL over the course of a century now," Eble said. "All these things can happen throughout the year within hurricane season and outside of it."
Recent lightning strikes
Last week, a lightning bolt killed Jake Rosencraz, 29, on a Florida beach while he was celebrating his honeymoon.
"The bolt literally came out of the blue sky and hit this person," said John Gumm, who saw it from his balcony.
In New York, a 15-year-old was struck and injured by lightning during a thunderstorm in Manhattan recently. Earlier this week, officials said 20 people were injured when lightning struck Lake Murray in South Carolina.
"It was very painful, kind of like a bunch of tasers just go off on you," said Tagen Billiot, who was swimming when she got hit.
Safety tips
If you're outside, remember this rule: When thunder roars, go indoors. The storm could have given way to blue skies or appear to be far away and still be dangerous.
The National Weather Service reminds people no place outside is safe during a thunderstorm and to stay in a safe shelter "at least 30 minutes after you hear the last sound of thunder."
If you are inside, the NWS advises you to stay away from equipment "that puts you in direct contact with electricity." It's also recommended to avoid being near plumbing, windows and doors.

Florida Boaters Capture Twin Waterspouts Up Close on Video
Living on Florida's Gulf Coast, Jeni Scheid has seen waterspouts before. But on Sunday, when she and her husband, D.J., took their boat out with family and a friend, they saw not one, but two of the funnel formations up close. The group had seen ominous clouds on the horizon and, as rain began to pour, decided to head back to dry land. But then Mr. Scheid pointed out water rising up from the Manatee River about 200 feet away from their 30-foot boat — the 'up-Scheid-down.' 'That's going to be a waterspout,' he said, Ms. Scheid recalled. Sure enough, one funnel came down from a spiraling cloud, and then a second. 'Our brains could not compute what we were seeing,' Ms. Scheid said in an interview. 'It looked like something from a movie.' Ms. Scheid and her husband try to take their boat out on the Manatee River in Bradenton, Fla., every Sunday. This time they went with their four children, a cousin and a friend. 'All the kids were excited, loved it, wanted to get closer,' Ms. Scheid said. The group began taking out their phones to capture the scene. But they did not chase the waterspouts and watched from a distance, Ms. Scheid said. Though awe-inspiring, waterspouts can be dangerous and carry winds that can reach up to 100 miles per hour, according to Austen Flannery, a meteorologist at the National Weather Service office in Tampa Bay, Fla. They are 'pretty common' in Florida in the summer, especially in the Keys, but seeing two at once is 'more infrequent,' he said. There are two types of waterspouts, Mr. Flannery said. One is essentially a 'tornado over water' that spins out of a thunderstorm, similar to what people might see on the Great Plains, he said. The dual waterspouts in Bradenton were 'fair weather waterspouts' that can happen during relatively calm weather when sea breezes collide or the leading edge of a thunderstorm brings a gusty front, Mr. Flannery said. Colder, denser air pushes warmer, more unstable air upward, creating a whirlwind, he said. Mayor Gene Brown of Bradenton and his wife also recorded a dramatic video of the twin waterspouts, which was shared by the Bradenton Police Department. The video also shows drivers stopping on a bridge to watch the funnels. Mr. Brown said the waterspouts caused no damage even though 'they were huge.' The rare brush with two spouts wasn't terrifying for Ms. Scheid once she realized how slowly they were moving, she said. It wasn't a tornado with debris flying, she added. When the boat returned to land, Ms. Scheid was surprised that people standing far away had seen the spouts. She realized that they had to have been huge. 'Every movie, you see when spirits or angels are going up to heaven,' Ms. Scheid said. 'That's what it looked like.' Michael Levenson contributed reporting.

Fireball spotted over Southeast US may have been caused by meteor, American Meteor Society says
The American Meteor Society has received numerous reports of a fireball over the US Southeast on Thursday afternoon – reports that are logged on its website. 'It looks to be a 'daytime fireball' that caused a sonic boom. This is usually indicative of a (meteor) dropping a fireball, but not always,' Mike Hankey, operations manager for the American Meteor Society, told CNN. The Federal Aviation Administration told CNN that there was no unusual aircraft activity in the area. 'Satellite-based lighting detection show a streak within cloud free sky over the NC/VA border,' the National Weather Service in Charleston said on X. 'This streak was detected between 12:51 to 12:56 p.m.,' NWS added. Analysis of satellite-based lightning detection by CNN show additional signatures over the Atlanta area. Dashcam video taken at approximately 12:30 p.m. in Forsyth, Georgia, shows a fireball descending to the ground. In Lexington County, South Carolina, dashcam video shows a big flash of light falling through the sky Thursday. South Carolina's emergency management division told CNN it is monitoring the situation. Brenda Eckard, 64, from Gilbert, South Carolina, said she was driving home when she saw a 'big flash in the sky come down and disappear.' She first thought it was a meteor which 'almost looked like a firework,' Eckard told CNN Thursday. Eckard then called her husband to check if their house was still standing. The Bootids meteor shower, a lower-level meteor shower, is ongoing this week, according to an American Meteor Society list. Fireballs are easier to view at night, but have to be much brighter to be visible during the day, meteorologists say. CNN has reached out to emergency management officials in North Carolina and Tennessee. The North American Aerospace Defense Command directed questions to NASA. CNN has reached out to NASA.

Mark Hensby holds onto an early lead at US Senior Open, even after tricky Broadmoor takes its toll
COLORADO SPRINGS, Colo. (AP) — Mark Hensby made seven birdies over the first nine holes Thursday at the U.S. Senior Open, and even after the greens at the Broadmoor and the major-championship conditions caught up with him, he left the course with the early first-round lead. The Aussie finished the day at 3-under 67, good for a one-shot lead over Bob Estes, Thomas Bjorn and three others with the morning rounds wrapping up and the afternoon wave hitting the course. Advertisement Miguel Angel Jimenez was part of a group of six that shot 69. It was Hensby who spent the entire morning in the lead, though after he signed his scorecard, he hardly looked like a player winning the U.S. Open. 'Obviously, I felt like I lost some out there,' he said. 'It's just frustrating. I played like (expletive) the back nine. What else can you say?' Hensby finished with a pair of bogeys, each coming after drives that missed the fairway and landed in rough that is thick — but not Oakmont thick, and not the biggest problem at this course nestled at the base of Cheyenne Mountain. 'There's so much slope, and it all comes off the mountain — most of the time,' Hensby said. 'Sometimes it doesn't. But the greens were softer today, so it kind of made it a little bit easier, and probably not as fast as they can get.' Advertisement A big storm Tuesday dumped water all over the course, but drier conditions are expected for the weekend. When the tournament was last played here in 2018, David Toms won with a score of 3-under par. Hensby reached 6 under after making birdie on the par-5 ninth — traditionally one of the easier holes. It would be no surprise if he's the first and last player to reach that number. 'The biggest thing is the greens,' said Shane Bertsch, a native of nearby Denver who was part of the group at 1 under. 'The greens are very, very severe. You can't ram at any putts. You're always kind of guessing a little bit because of all the mountain break and everything.' ___
