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 just over a month until the election, Florida and Arizona are emerging as battleground states that are neck-and-neck for President Donald Trump and former vice president Joe Biden.For the first time in 2020, Trump has a slight lead in Florida, according to the Washington Post-ABC News poll. Among participants who said they are likely voters, Trump leads 51-to-47 percent, however this is considered within the margin of error.The poll points out Biden has a 13-point lead among Hispanic registered voters in Florida; four years ago, Hillary Clinton had a 27-point lead among Hispanics and still lost the state.In Arizona, among likely voters, the poll shows Trump and Biden at 49-to-48 percent. Arizona has voted for the Republican presidential candidate for every election since 1952 except once, the re-election of Bill Clinton in 1996.Researchers of this poll note that these percentages are so close the difference is not statistically significant. The margin of sampling error is 4 points among Florida results and 4.5 points among Arizona results.Trump won Florida and Arizona in the last election. In Arizona, Trump won in 2016 by about 90,000 votes. In Florida, Trump won by just over 100,000 votes.When it comes to the issues, Trump gets credit for being trusted to handle the economy, despite the current pandemic-fueled recession. In Florida, registered voters in the survey said they trusted Trump with the economy over Biden 52-to-41 percent. In Arizona, the spread is higher, with registered voters preferring Trump 56-to-41 percent.The economy appears to be the top issue for many this election cycle. About 31 percent of registered voters in Florida said the economy is the single most important issue, and 33 percent of those in Arizona.In handling the coronavirus pandemic, more registered voters trust Biden over Trump, with 48-to-43 percent in Florida and 49-to-45 percent in Arizona. In both states, 57 percent of participants said they were worried about catching the coronavirus.Biden also leads in handling health care, crime and safety, discouraging violence at political protests, and equal treatment of racial groups.Trump’s overall approval rating among registered voters is 47 percent in both states.There is also a big split in how voters of different parties plan to vote on Election Day. In both Florida and Arizona, more than 70 percent of registered Republicans plan on voting in-person on Election Day. Democratic participants are more likely to vote early or absentee/mail-in, more than 60 percent.This latest poll was conducted by landline and cell phone interviews between September 15-20 among 765 registered Florida voters and 701 registered Arizona voters. 2712

When it comes to educating America's children, how much of a difference could million make? Could it send a second grader on a school trip to the museum, or provide updated equipment to a class of budding scientists?It can. In fact, it can do it 35,647 times.Ripple, a cryptocurrency and international payment company, has donated million in cryptocurrency to DonorsChoose.org, a donation platform that connects people to classroom needs across the country. With the money, Donors Choose was able to fulfill every single classroom project request on its site -- 35,647 requests in all, from 28,210 teachers at 16,561 public schools."It's fair to say there's never been a day that this many classroom dreams have come true," Donors Choose founder Charles Best told CNN.The Colbert bumpThe massive donation is the culmination, or grand finale, if you will, of the site's #BestSchoolDay project. Two years ago, Stephen Colbert, who is a member of the Donors Choose board of directors, announced he was going to pay for every school project request in his home state of South Carolina.His act of kindness set off a movement that became known as #BestSchoolDay."More than 50 actors, athletes and philanthropists were inspired to fund classrooms in their states," Best told CNN. "Together, those 50-plus people gave more than million, and to use, that represented the idea of a best school day."Best says the response has been overwhelming -- in a good way."An outpouring of joy would not be an overstatement," he said.The Ripple effectBest says when the organization connected with Ripple, the cryptocurrency management company was "inspired to think of the impact" of such a significant gift."At Ripple, we care about giving back to our community and we collectively value the importance of quality education in developing the next generation of leaders," Ripple's SVP of Marketing Monica Long said in a statement."DonorsChoose.org's track record speaks for itself — they are highly effective at improving the quality of education and the experience of teachers and students across America. We're proud to work with them to support classroom needs across the country."According to Ripple's company site, the donation will affect approximately 1 million public school students.Best says the "classroom projects" requested on the site represent specific missions or activities that teachers have for their students."It's a public schoolteacher requesting a classroom library. A field trip. A set of art supplies. A pair of microscopes. It's about requesting experiences or tools to provide a student learning experience," he said."We believe in the wisdom of the front lines," Best added. "Hardworking, passionate teachers know their students' needs better than anyone else in the school environment. If we can tap into their needs, we can unleash smarter solutions and empower those people on the front lines."  2956

Images for the Amazon Augmented Reality app show drawings on the pumpkin seeming to come to life as a jack-o-latern.Images on the app description page show different box designs with a corgi dog and car option. No word on when those box designs could be hitting doorsteps.The boxes are also made with less material as part of Amazon’s ongoing effort to create less packaging. 912

Why are stocks falling again? President Donald Trump says it's because Democrats are gearing up to use their impending control of the House of Representatives to investigate him. As always, when it comes to the markets, the real answer is complicated.The Dow fell by more than 600 points on Monday, dragged down by investors' concerns about the tech sector and the rising dollar. The Nasdaq fell 2% and the broader S&P 500 fell 1.2%.Apple (AAPL) fell 5% after supplier Lumentum cut its earnings and sales forecast because of weak demand, and JPMorgan cut its target price on Apple's stock. That weighed on other technology stocks, including Amazon (AMZN) and Tesla (TSLA) -- down 4% -- as well as Facebook, which fell 3%. Google (GOOGL), Netflix (NFLX) and Microsoft (MSFT) were all down more than 2%.The strong dollar also weighed on stocks. The US currency surged to a 16-month high because investors fear the European economy could stall if no Brexit deal is reached this week. Prospects of another rate hike from the Fed next month have also helped lift the dollar. The rising dollar is a signal of a strong economy, but it hurts sales and profits for American companies that do business overseas.Though Trump blamed Democrats for the drop, the Dow had actually bounced back since the midterms, rising last week in its best showing since March. Wall Street tends to like stagnation in Washington, so investors are actually just fine with Democrats taking the House.As for what Trump termed the "prospect of presidential harassment," there is not much evidence the stock market will bat an eye if Democratic leaders in the House begin investigations into the Trump administration. Stocks rose before, during and after President Bill Clinton's impeachment. 1800
