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

When we hear our phone go off and see an unknown number, we're not very likely to answer, but that habit is creating some issues for contact tracers.People are hired to get in touch with anyone who's been in contact with someone who has been diagnosed with COVID-19.With people not answering calls from contact tracers, controlling the coronavirus becomes more difficult.But it doesn't mean contact tracers give up.“In some cases, when contact tracers call someone, and that person is uncomfortable talking to them on the phone, in some counties, they will actually send someone to that person's home to conduct an in-person interview, if they're more comfortable doing that,” said Steve Waters, founder and CEO of CONTRACE.Even when contact tracers do manage to get someone on the phone, it can be difficult to get information from them. This is a result of all the spam calls trying to scam people.That's why contact tracers say it's all about establishing trust in that cold call.“If you have a cultural understanding of the people that you are calling, that goes a long way to begin with,” said Waters. “I think you are more likely to be trusting of someone who has the demeanor and cultural understanding of your region, than somewhere across the country.”CONTRACE was founded when coronavirus cases started popping up in the U.S. It helps public and private groups with contact tracing efforts.The group encourages every state and local government to work with phone providers to help people know that calls are coming from contact tracers.Ideally, the call would be identified as the local health department or contact tracing program. 1650

When it comes to free food, demand is up and donations are down.To help feed the hungry, volunteers have turned a school parking lot into a pantry.“That’s what's important,” said Maria Estrada with the Wyatt Academy, a charter school in Denver, Colorado.Once a week, her teams passes out free bags of food to families and to people like Marco Esparza.“I’m getting some apples and potatoes,” he said.For Esparza, these donations more than just feed his family.“With this kind of pandemic, it helps us to stay safe at home."Since COVID-19 hit, Estrada says more people are requesting food donations across the country while volunteers adjust to the new norm and practice new safety guidelines.“Things are different,” Estrada said about food donation centers. “We now have to make sure everybody is wearing gloves. We want to make sure everybody is being safe. Everybody has their masks on. We’re trying to keep everybody social distanced.”Estrada says the COVID-19 crisis is creating somewhat of a national food shortage crisis. That’s why they’re now partnering with the YMCA.“When COVID hit, YMCAs across the country started to support food programming,” said Katie Canfield with the YMCA.Nationwide, the YMCA has provided 37 million meals to more than one million people in the last six months. That’s an increase of more than 25% since the same time last year as they now deal with new safety regulations.“We are making sure that our community is using hand sanitizer,” Canfield said. “We are currently handling the food and then we hand them the bag when its complete.”Moving forward, the YMCA hopes to go mobile and bring food straight to people’s houses.But for now, they’ll focus on helping feed people in person. 1727

White House chief of staff John Kelly told reporters on Friday that the White House's handling of classified material "wasn't up to the standards" he had previously seen in his governmental career.During an impromptu meeting with reporters after President Donald Trump had departed for the weekend, Kelly explained the security clearance process for White House officials."It came to my notice that the kind of things I was used to in (Department of Defense) in terms of the handling of classified material wasn't up to the standards that I'd been used to," he said.  580
