ATLANTIC CITY, N.J. (AP) — The federal government is warning Americans to brace for a "floodier" future.Government scientists predict 40 places in the U.S. will experience higher than normal rates of so-called sunny day flooding this year because of rising sea levels and an abnormal El Nino weather system.A report released Wednesday by the National Oceanic and Atmospheric Administration predicts that sunny day flooding, also known as tidal flooding, will continue to increase."The future is already here, a floodier future," said William Sweet, a NOAA oceanographer and lead author of the study.RELATED: Devastating 'ARk' storm envisioned for California by U.S. Geological SurveyThe report predicted that annual flood records will be broken again next year and for years and decades to come from sea-level rise."Flooding that decades ago usually happened only during a powerful or localized storm can now happen when a steady breeze or a change in coastal current overlaps with a high tide," it read.The nationwide average frequency of sunny day flooding in 2018 was five days a year, tying a record set in 2015.But the East Coast averaged twice as much flooding.The agency says the level of sunny day flooding in the U.S. has doubled since 2000.Nationwide, the agency predicted, average sunny day flooding could reach 7 to 15 days a year by 2030, and 25 to 75 days a year by 2050.RELATED: How to check if your neighborhood is at risk of flooding"We cannot wait to act," said Nicole LeBoeuf, acting director of NOAA's Ocean Service. "This issue gets more urgent and complicated with every passing day."Global sea levels are rising at a rate of about 3 millimeters a year, or about an inch every eight years, according to Rutgers University researchers, who predict that by 2050, seas off New Jersey will rise by an additional 1.4 feet (0.4 meters).The study noted floods interfering with traffic in northeast states, swamping septic systems in Florida and choking Delaware and Maryland coastal farms with saltwater over the past year.Baltimore experienced 12 days of high-tide flooding from 1902 to 1936. Within the last 12 months, it experienced an additional 12 days.Robert Kopp, a leading climate scientist with Rutgers University, who was not involved in the study, said it confirmed many well-established trends."It's simple arithmetic: If you have higher sea level, you will have tides causing flooding," he said. "We're not talking about disaster flooding. We're talking about repetitive flooding that disrupts people's lives on a daily basis. It's sometimes called 'nuisance flooding,' but it has real impacts and costs."RELATED: Mega storm could cause billions in damage to California, report showsThe report cited the disruption of commerce in downtown Annapolis, Maryland, where parking spaces are lost to flooding. A 2017 study put the price tag on lost economic activity at as much as 2,000. The water table has risen to ground level and degraded septic systems in the Miami region, and farmlands in the Delmarva Peninsula in Delaware and Maryland have been damaged by salt water encroaching into planted areas.High-tide flooding is causing problems including beach erosion, overwhelmed sewer and drinking water systems, closed roadways, disrupted harbor operations, degraded infrastructure and reduced property values — problems which "are nearly certain to get much worse this century," the report read.The report's statistics cover May 2018 through April 2019.The agency forecasts sunny-day flooding this year in Boston at 12 to 19 days (it had 19 last year). It predicted sunny-day flooding this year in New York (8 to 13 days, compared with 12 last year); Norfolk, Virginia (10 to 15 days; compared to 10 days last year); Charleston, South Carolina (4 to 7 days, compared to 5 last year); Pensacola, Florida (2 to 5 days compared with 4 last year); Sabine Pass, Texas (6 to 13 days compared with 8 last year) and Eagle Point, Texas (29 to 40 days, compared to 27 last year).West coast predictions included San Diego (5 to 9 days compared to 8 last year); Los Angeles (1 to 4 days compared to 5 last year); Humboldt Bay, California (6 to 12 days compared to 12 last year); Toke Point, Washington (9 to 21 days compared to 12 last year) and 2 to 6 days in Seattle, compared to 2 last year.The report documented that 12 locations broke or ties their record of sunny day flooding last year, including 22 in Washington, D.C., 14 in Wilmington, North Carolina; and 12 each in Baltimore and Annapolis.FEMA created flood maps of San Diego County which enable users to search by their address.

Authorities are investigating interference with police radio communications, websites and networks used by law enforcement and other officials during recent U.S. protests over the death of George Floyd in Minneapolis.Although the efforts to disrupt police radios and take down websites in Minnesota, Illinois and Texas aren’t considered technically difficult hacks, federal intelligence officials warned that law enforcement should be ready for such tactics as protests continue.Authorities have not yet identified anyone responsible or provided details about how the disruptions were carried out. But officials were particularly concerned by interruptions to police radio frequencies during the last weekend of May as dispatchers tried to direct responses to large protests and unrest that overshadowed peaceful demonstrations.During protests in Dallas on May 31, someone gained access to the police department’s unencrypted radio frequency and disrupted officers’ communications by playing music over their radios, according to a June 1 intelligence assessment from the U.S. Department of Homeland Security.Dallas police did not respond to questions about the incident.The assessment, which was obtained by The Associated Press, attributes the Dallas disruption to “unknown actors” and does not say how they accessed the radio frequency. It warned that attacks of various types would likely persist.“Short-term disruptive cyber activities related to protests probably will continue — various actors could be carrying out these operations — with the potential to use more impactful capabilities, like ransomware, or target higher profile networks,” the assessment warns.The assessment noted similar problems with Chicago police’s unencrypted radio frequencies during large downtown protests on May 30 followed by reports of arson, theft and vandalism. Chicago police also have not said how the radio frequencies were accessed, but an official with the city’s Office of Emergency Management and Communications told the Chicago Sun-Times that the tactic was “very dangerous.”Police around the country have encrypted their radio communications, often arguing that it’s a way to protect officers and block criminals from listening in on widely available phone apps that broadcast police radio channels. But media outlets and local hobbyists have been frustrated by the changes, which also prevent them from reporting on issues pertaining to public safety.The Department of Homeland Security issued a separate warning this week reporting that personal information of police officers nationwide is being leaked online, a practice known as “doxxing.” According to the report obtained by the AP, information shared on social media included home addresses, email addresses and phone numbers.Law enforcement agencies have been targeted by online pranksters or hackers in recent years, including by some who claimed to be motivated by on-the-ground protests against police tactics. For example, the hacking collective Anonymous claimed responsibility for the defacement of local police departments’ websites in 2012 as protesters clashed with officers during the Occupy Wall Street movement.Individuals who self-identified as being part of the collective also claimed to have accessed dispatch tapes and other Ferguson Police Department records in 2014 after a white police officer shot and killed Michael Brown, an 18-year-old black man.Like other government entities, law enforcement agencies in recent years have been frequently targeted by ransomware attacks, in which a perpetrator virtually locks up a victim’s computer files or system and demands payment to release them.The prevalence of cyberattacks — which can cause physical damage or far-reaching disruption — and less severe online trickery, such as stealing passwords, has given law enforcement agencies more experience at fending off efforts to take down their websites or access critical information. But hackers adapt too, and governments with fewer resources than private companies often struggle to keep up, said Morgan Wright, chief security officer for the cybersecurity company SentinelOne.“The biggest concern they have right now is the safety of their communities, the safety of their officers,” Wright said of how law enforcement agencies view cyberthreats amid large demonstrations and unrest. “But if you look at what underpins everything we use to communicate, collaborate and operate, it’s all technology.”As large protests gathered steam after the May 25 death of Floyd, a handcuffed black man who died after a white Minneapolis police officer used his knee to pin his neck down for several minutes, Minnesota Gov. Tim Walz said state networks had been targeted. He described the activity as a “a very sophisticated denial of service attack.”But experts said the strategy of bombarding a website with traffic is common and doesn’t always take a high level of skill, counter to Walz’s description. Minnesota’s Chief Information Officer Tarek Tomes later said state services weren’t disrupted.But the efforts got a lot of attention, partly due to unverified online claims that Anonymous was responsible after years of infrequent activity. The decentralized group largely went quiet in 2015 but is still known globally based on headline-grabbing cyberattacks against Visa and MasterCard, the Church of Scientology and law enforcement agencies.Twitter users also made unverified claims that Anonymous was behind recent intermittent outages on the city government’s website in the Texas capital of Austin. Their posts indicated that the disruption was retribution for police officers shooting a 20-year-old black man in the head with a bean bag during a May 31 protest outside of police headquarters.The injured protester, identified by family as Justin Howell, remained hospitalized Wednesday in critical condition.The city’s IT department was looking into the site’s issues, but a spokesman said Monday that he couldn’t provide any information about the cause. He said the website was still experiencing a high volume of traffic.“You should have expected us,” an account purporting to be Anonymous’ posted on Twitter. It also warned that “new targets are coming soon.”The collective’s approach — anyone can act in its name — makes it difficult to verify the recent claims of responsibility. But Twitter accounts long affiliated with Anonymous shared them, said Gabriella Coleman, a professor at McGill University in Montreal who has studied the Anonymous movement for years.People with more advanced and disruptive hacking skills often drove peak instances of attention for Anonymous, and it’s not clear whether that type of activity will resume, she added.“There’s a lot of things going on in the background, people are chatting,” Coleman said. “Whether or not it materializes is another question. But certainly people are kind of aroused and talking and connecting.”___Foody reported from Chicago.

ATLANTA, Ga. – While residents along the Gulf Coast seek shelter from Hurricane Laura, they should still keep the threat of COVID-19 in mind.Emergency managers, shelter managers, and public health professionals are taking measures to reduce the possible spread of the coronavirus among people who seek safety in a disaster shelter during severe weather events like this.For those staying in a shelter during the storm, the Centers for Disease Control and Prevention (CDC) offered some tips to lower the risk of coronavirus infection:Preparing to shelterIf you need to evacuate, the CDC says to prepare a “go kit” with personal items you cannot do without during an emergency. That includes items that can help protect you and others from COVID-19, like hand sanitizer with at least 60% alcohol, soap, disinfectant wipes, and two masks for each person.Know a safe place to shelter and have several ways to receive weather alerts, such as the National Weather Service’s cell phone alerts, NOAA Weather Radio, or NWS alerts on Twitter.Find out if your local public shelter is open, in case you need to evacuate your home and go there. Your shelter location may be different this year due to the COVID-19 pandemic.Follow guidance from your local public health or emergency management officials on when and where to shelter.Make a plan and prepare a disaster kit for your pets. Find out if your disaster shelter will accept pets. Typically, when shelters accommodate pets, the pets are housed in a separate area from people.Follow safety precautions when using transportation to evacuate. If you have to travel away from your community to evacuate, follow safety precautions for travelers to protect yourself and others from COVID-19.While in a public shelterPractice social distancing. Stay at least 6 feet from other people outside of your household.Follow CDC COVID-19 preventive actions—wash your hands often, cover coughs and sneezes, and follow shelter policies for wearing masks. Avoid sharing food and drink with anyone if possible.Follow disaster shelter policies and procedures designed to protect everyone in the shelter, especially those who are at higher risk for severe illness from COVID-19, including older adults and people of any age who have serious underlying medical conditions.Avoid touching high-touch surfaces, such as handrails, as much as possible. Wash hands with soap and water for at least 20 seconds or use hand sanitizers with at least 60% alcohol immediately after you touch these surfaces.Keep your living area in the shelter clean and disinfect frequently touched items such as toys, cellphones, and other electronics.If you feel sick when you arrive at the shelter or start to feel sick while sheltering, tell shelter staff immediately.Keeping children safe in sheltersTeach and reinforce everyday preventive actions for keeping children healthy.Make sure children aged 2 and older wear masks. Masks should not be used by children under the age of 2. They also should not be used by people having trouble breathing, or who are unconscious, incapacitated, or unable to remove the mask without assistance.Be a good role model—if you wash your hands often, your children are more likely to do the same.Help your children stay at least 6 feet away from anyone who is not in your household.Watch your child for any signs of illness and tell shelter staff if your child may be ill.Try to deal with the disaster calmly and confidently, as this can provide the best support for your children. Help children cope with emergencies. 3559

  

At age 106, Sen. John McCain's Roberta McCain mother will be in attendance at the late senator's funeral this Saturday in Washington, D.C., and his burial service in Maryland, the Associated Press reported. Roberta McCain has outlived the son she called "Johnny," as the U.S. Senator from Arizona died on Saturday at the age of 81. Sen. McCain will be lain in state at the U.S. Capitol on Friday before his final services on Saturday. Roberta McCain, at age 96, was active on the campaign trail for her son during his presidential bid. She also made a number of appearances on television, including one controversial spot on MSNBC's Hardball, where she went after fellow GOP presidential hopeful Mitt Romney. Roberta McCain had an identical twin sister, Rowena Wright, who died at the age of 99 in 2011.  842

  

Authorities in Costa Rica say that a body has been found on the Airbnb property where missing Florida woman, 36-year-old Carla Stefaniak, was staying.Costa Rica's Judicial Investigation Agency (OIJ) tells WFTS that the body was buried in a mountainous area located in the back of the property, less than 200 feet away from where Stefaniak had been staying. OIJ agents had been searching the area with specialized dogs. At this time, authorities have not been able to confirm that the body is Stefaniak.In Spanish, Walter Espinoza, the director general of the OIJ said, “the body was in a state of decomposition but the preliminary observation does verify the body is a woman.”In a press conference on Monday, Espinoza said that biological fluids consistent with blood were discovered inside the Airbnb property. The blood has been sent to labs for testing.The body cannot be positively identified by officials until an autopsy is performed.Stefaniak hasn't been seen or heard from since Tuesday, November 27. She traveled to Costa Rica with her sister-in-law, April Burton, on November 22 to celebrate her birthday. Burton flew back on November 27. Stefaniak had plans to return to the United States on November 28, bound for Florida, but never arrived for her flight. She checked into her Airbnb, located at Calle Hoja Blanca in San Antonio de Escazú, for one night on November 27. According to Burton, the last thing they knew about Stefaniak was that she was inside that Airbnb on the night of November 27. The last time Burton spoke to Stefaniak, she told her that it was raining crazy and the power went out. She continued with, "it's pretty sketchy here," according to Burton.The final photograph Stefaniak sent family members was from inside the Airbnb. Family members shared the image with WFTS, seen below.</p><p>"The guards (at the apartment complex that housed the Airbnb) told us that she left at 5 in the morning with all of her bags and got into an Uber. She wouldn’t do that, her flight was at 1:30 p.m. She’s never been early for anything in her life she wouldn’t leave to go to the airport at 5:30 a.m.," Burton said.The Airbnb listing for "Villa Buena Vista" has since been removed from Airbnb's website.WFTS spoke to Airbnb officials, who say they have reached out to Carla's family as well as the FBI, OIJ and the local embassy.Stefaniak's brother flew down to Costa Rica on Friday to search for his sister. Her father flew down to Costa Rica on Monday afternoon.This is a developing news story and will be updated as more information becomes available. 2718
