With hurricane season in full swing, there's a lot of talk from meteorologists about hurricane "categories." What do they mean, and what do they tell us about a storm?It turns out, a hurricane's category is only based on one thing: wind speed.According to the National Hurricane Center's website, the agency relies on the Saffir-Simpson Hurricane Wind Scale to determine a storm's strength. The scale categorizes a hurricane on a 1-5 scale, based on the storm's maximum sustained winds — the one-minute average of the wind speed taken from inside the storm.When storms over the Atlantic begin to organized into a rotating system around a central "eye," and sustained wind speeds in the storm reach 39 mph, it's classified as a tropical storm. Once wind speeds in the system reach 74 mph, it becomes a hurricane.From there, the NHC uses the Saffir-Simpson Scale to determine how much destruction a hurricane is expected to inflict on an area. While any hurricane is expected to cause damage to homes and topple some trees in its path, higher wind speeds can lead to trees blocking roads and downing power lines, isolating communities without power or access to water for weeks — or even months.STRENGTHMAX SUSTAINED WIND SPEEDDESTRUCTION CATEGORY 1Between 74 mph and 95 mphWell-constructed houses could have damage to roof, shingles, vinyl siding and gutters. Large branches of trees will snap and shallowly-rooted trees may be toppled. Extensive damage to power lines and poles likely will result in power outages that could last a few to several days. CATEGORY 2Between 96 mph and 110 mphHouses could sustain major roof and siding damage. Many shallowly rooted trees will be snapped or uprooted and block roads. Near-total power loss is expected with outages that could last from several days to weeks. CATEGORY 3 (major)Between 111 mph and 129 mphHouses may incur major damage or removal of roof decking and gable ends. Many trees — regardless of root depth — will be snapped or uprooted, blocking roads. Electricity and water will be unavailable for several days to weeks after the storm passes.CATEGORY 4 (major)Between 130 mph and 156 mphHouses can sustain severe damage with loss of most of the roof structure and possibly some exterior walls. Most trees will be snapped or uprooted and power poles will topple. Fallen trees and power poles will isolate residential areas. Power outages will last weeks to possibly months. Most of the area will be uninhabitable for weeks or months.CATEGORY 5 (major)Above 157 mphA high percentage of framed houses will be destroyed, with total roof failure and wall collapse. Fallen trees and power poles will isolate residential areas. Power outages will last for weeks to possibly months. Most of the area will be uninhabitable for weeks or months.Any hurricane that reaches Category 3, with sustained winds above 111 mph, is considered a "major" hurricane. According to the NHC, that's because "of their potential for significant loss of life and damage." But that doesn't mean Category 1 and 2 hurricanes can't be deadly.The NHC itself says that Category 1 and 2 hurricanes are "still dangerous" and "require preventative measures."While Hurricane Sandy peaked at Category 3 intensity when it made landfall in Cuba in 2012, it had collapsed into a post-tropical cyclone by the time it reached New Jersey on Oct. 29. Even though the storm only had Category 1 strength winds, it still resulted in the deaths of 131 people in America, according to media reports, and an estimated billion in damages — the second-costliest hurricane in U.S. history up to that point.The Saffir-Simpson Scale also doesn't take into account storm surge in coastal areas and flash flooding caused by the surge and heavy rain. Flooding can cause significant property damage and make main roads — including expressways — inaccessible. 3864

With his pledge to save a major Chinese company from crippling US sanctions, President Donald Trump has delivered yet another twist in the trade clash with Beijing.His announcement on Twitter that he's working to give China's ZTE "a way to get back into business, fast" was a sudden shift in the US stance at the start of a big week for trade ties between the world's top two economies.Washington and Beijing have threatened to impose tariffs on tens of billions of dollars of each other's products, fueling fears of a full-blown trade war.Talks in Beijing earlier this month aimed at dialing down the tensions failed to produce any major breakthroughs. But Chinese President Xi Jinping's top economic adviser is heading to Washington this week for more negotiations. American companies will also have a chance to publicly tell the Trump administration what they think about its planned tariffs on Chinese goods.Here's what to keep an eye on this week. 960

WIMAUMA, Fla. — A Florida deputy surprised a mother with new car seats instead of issuing her a ticket.Hillsborough County Deputy Jacky Nguyen was running traffic enforcement when he pulled over a mother for a minor traffic violation."As I approached the car, I saw two children in the backseat. They were without a car seat and looked to be young," said Deputy Nguyen.The deputy issued the mother a warning for the traffic violation but noticed her children, ages 3 and 5, were not properly restrained in the backseat."Just through conversation, I realized she may have been through some financial difficulties, She mentioned car seats are quite expensive, which they are," said Nguyen.Nguyen has a 5-year-old son himself. 731

When Linda Beigel Schulman heard that a geography teacher was among the victims of the Parkland shooting, she knew it was her son. And she knew she had to be with him.Schulman, her husband and her brother rushed to look for flights out of the New York area. They couldn't find an open seat with a commercial airline, so they called Talon Air, a charter jet company, to fly to Scott's side.The company's clients include Martha Stewart and Lebron James, according to their website."I had no idea what the charge was at the time. It really didn't matter what the charge was," she told CNN. "I was convinced in my mind that my son was in the hospital and I needed to get to him as fast as possible."What Schulman did not expect, however, was that she would be charged an additional ,000 for the empty plane's return to New York the next day, bumping the bill up to a total of ,459.13 dollars.Once she landed, Schulman learned her son, Scott J. Beigel, had died that February day after unlocking his classroom door to allow students to seek shelter. He was one of the 17 people who lost their lives after Nikolas Cruz opened fire in the halls of Marjory Stoneman Douglas High School.The family promptly paid the whole amount with funds from Scott's life insurance policy. But they asked Talon Air to reconsider the return flight charge since they did not travel back on the plane. The company refunded ,000 dollars and told them it was all they could do. 1475

What's in a name? A lot, if you happen to be a member of Britain's royal family.As the Duke and Duchess of Cambridge on Monday announced the arrival of their son and third child, speculation turned to a possible name.The baby boy was born at St. Mary's Hospital in London at 11 a.m. local time, Kensington Palace said in a statement.But as with the royal couple's older children, Prince George, 4, and Princess Charlotte, 2, it is likely to be a few days until a name is announced.Among the bookmaker's favorites for the boy, who will be fifth in line to the throne, are Arthur, Albert and James.Tradition plays a huge role when choosing a royal name. Albert could be a nod to both Queen Victoria's husband, Prince Albert, and Queen Elizabeth II's father, King George VI, who was called Albert until his accession to the throne."We haven't had so many called Arthur, but it does hark back to the mythical first king of Britain," said royal commentator Kate Williams.Given Prince William and Catherine's previous choices, royal commentators are predicting the couple will stick with a traditional name for their third child."George and Charlotte are very traditional, historic, English names," said Williams. "Although this is slightly different in that their first child, Prince George, is likely to be the monarch, and this child will likely not. So they can be a little bit different with the name."The latest edition to the royal family is fifth in line to the throne -- after his grandfather Prince Charles, father William and two siblings -- bumping William's brother Prince Harry further down the order.A change in the law in 2011, after William and Kate were married, gave women the same rights of accession to the throne as men.Whichever name the Duke and Duchess choose, it will first need to be cleared with Queen Elizabeth II, though ultimately the final decision rests with the parents."The Queen has the power to say what their title is -- she'll decree that they are the Prince of Cambridge," explained Williams."But in the case of names, it is more of an informal conversation. Of course they have such respect for the Queen that if she says 'I really don't like that name,' they'd definitely take that into account," Williams added.One thing is certain, their chosen name is likely to shoot to the top of British baby name lists -- as it did with George and Charlotte.And with the royal wedding of Prince Harry and Meghan Markle set to take place on May 19, Williams had one final prediction: "I wouldn't be surprised if Harry and Meghan are popular baby names in the coming year."  2611
