The 2020 hurricane season is already breaking records.Hurricane Isaias, which just passed through the Carolinas and the northeast, killing several people, was the season’s ninth named storm, making it the earliest in a year we have ever reached that number.It was also the fifth storm of the season to make landfall. It’s the fastest we’ve gotten to five land-falling storms since the old record set back in 1916."From a landfall perspective, this has already been a very, very active landfall season,” said Dr. Phil Klotzbach, from Colorado State University’s Tropical Weather and Climate Research Center.The group released its final predictions for the 2020 hurricane season on Wednesday, predicting above-average activity with 24 named storms and 12 hurricanes, five of them being major hurricanes of Category 3 strength or greater."Typically, we do one final update in early August to give you one final last best estimate to see what the season’s going to be like, and if we realized we really screwed things up until now, it’s one last shot at a mulligan,” Klotzbach explained.Before you say these records are just par for the course in 2020 there is a caveat. The 2020 season has not produced nearly the same amount of Accumulated Cyclone Energy, or ACE, as past years.For example, there were fewer named storms by this time in 2005, but the storms that did form in the Atlantic through the end of July of that year produced far more energy, including Hurricane Dennis, a Category 4, and Emily, a Category 5. That hurricane season went on to produce Hurricane Katrina, which battered New Orleans, and Hurricane Wilma, making it the worst hurricane season in recorded history.“Normally, a lot of storm activity in June and July doesn’t say much about how active the season is,” said Klotzbach.Klotzbach says the two big predictors of a hurricane season are ocean temperature in the deep tropics and wind shear, which is how wind direction changes at different levels of the atmosphere.This year, water in the Tropical Atlantic is the fourth warmest on record, meaning there is more fuel for hurricanes. July also had the second-lowest vertical wind sheer on record, meaning there is not much to cap a storm’s potential.It is why Klotzbach thinks once the peak of hurricane season arrives on August 20, we will have to make sure we are ready for whatever is thrown our way.“The primary reason why we’re forecasting such an active season isn’t as much the storm activity that we’ve already had, but the large-scale conditions we’ve observed during July and what we expect to see during the peak of the season,” said Klotzbach. 2638

TAMPA, Fla. — University of South Florida Professor Dr. Jay Wolfson and health experts around the world are studying the latest research project on the coronavirus."This thing gives us surprises almost every week. We learn something new, and it's usually unpleasant every week," said Wolfson.The new research is from Australia's National Science Agency, and it found the virus could survive and remain infectious on surfaces like glass, steel, and paper for up to 28 days."What they are concerned about, what we are all concerned about it, is if you have some viable virus on your fingers and you touch your eyes or you touch your nose or you touch your friend's eyes or nose, there's a greater risk of it being brought into the body if there's enough of it there," said Wolfson.But Dr. Thomas Unnasch, also with USF Health, says this study was done with perfect conditions for a virus to thrive."They put the virus under different surfaces and then preserve them in the dark at ideal temperatures and humidity. So it's not too surprising that under those ideal conditions, that it would last quite a bit longer than it would under normal conditions."While experts agree COVID-19 primarily spreads from person to person through droplets in the air, there is still more to understand about how it can transfer from objects or surfaces to people."People do have a proclivity to touch their face and their eyes, so if you are in a place that's not familiar to you and you are using things that are unfamiliar to you, just be careful," said Wolfson."Your own cell phone, if you are the only one using it, that's not a big deal. But door handles, faucet handles elevator buttons things like that. Wash your hands after you do that. That's a really good idea," said Unnasch.All of the experiments in this study were done in the dark. Research has shown direct sunlight can kill the virus.This story was first reported by Erik Waxler at WFTS in Tampa Bay, Florida. 1965

Teachers in the San Diego Unified School District say they may have to strike if they can't reach an agreement on a new contract with the district."It's not something we ever want to do," says Lindsay Burningham with the San Diego Education Association, the union that represents teachers. "But it's something that we will do if the district doesn't show the respect our students and educators deserve."Teachers first brought up the threat of a strike at this month's school board meeting, where they urged board members to hear their demands.The two sides have been in negotiations since June when the last contract expired. Since then, teachers in the district have been working without a contract. The final negotiating session between the two is scheduled for Thursday, March 22.For the new contract, they're asking the district to "LEARN."Lower Class Sizes 884

  

Sumner Redstone, who built a media empire from his family’s drive-in movie chain, has died. He was 97. Redstone built his operations through aggressive acquisitions, but many headlines with his name focused on his severing ties with wives, actors and executives. In multiple interviews, he said he’d never die.His tight-fisted grip on the National Amusements theater chain, which controls both CBS Corp. and Viacom Inc. through voting stock, has been passed down to his daughter Shari Redstone, who battled top executives to re-merge the two entities that split in 2006. 578
