Labor Day marks the unofficial end of summer throughout the U.S. — and the Denver area seemingly took that to heart by skipping straight to winter on Tuesday.Just after noon on Monday, Denver recorded temperatures of over 90 degrees. Less than 24 hours later, temperatures had plummeted to near freezing, and snow was falling in parts of the city.A powerful cold front was the culprit for the sharp change in temperatures. The system will bring winter weather to the Denver area through Wednesday evening.According to meteorologists with Scripps station KMGH in Denver, between 3 and 7 inches of snow is expected to fall in the Front Range corridor by early Wednesday.There are also freeze warnings in effect for the Colorado plains east of Denver, where temperatures are expected to dip below freezing by Wednesday morning.Officials fear the early freeze could damage crops, some of which are about to be harvested. Officials also fear that a deep freeze with full foliage could cause tree limbs to snap and cause power outages in the area.KMGH reports that Denver's earliest snow of the season came Sept. 3, 1961, when a Labor Day storm brought 4.2 inches to the city's airport and dumped nearly a foot in the western suburbs and foothills. On Sept. 8, 1962, Denver saw its earliest freeze of the season when temperatures dipped to 31 degrees.Wednesday's snowfall was Denver's earliest in the last decade. The previous record for earlier snowfall in the last 10 years came Oct. 5, 2012. Last year's first snow came earlier than usual on Oct. 10 — still a full month earlier than Tuesday's snowfall.The enormous temperature swing between Monday and Tuesday could also turn out to be the largest swing on record. The previous record occurred on Jan. 25, 1872, when the temperature dropped 66 degrees, from 46 degrees to -20 degrees.Monday also marked Denver's 73rd day in 2020 with temperatures in the 90s, which ties an all-time record. The city could break that record by early next week when temperatures are expected to climb back into the high 80s. 2061

LAS VEGAS, Nevada — A poem about the Oct. 1, 2017 mass shooting penned by a Las Vegas Metropolitan Police Department captain was unveiled at police headquarters on Thursday. LVMPD Captain Harry Fagel is a lifelong poet. His poem "The Route" about the 1 October shooting was unveiled at police headquarters, marking the end of a series of 1 October remembrance events. After Fagel wrote the poem, art collector and Nevada School of the Arts president and CEO Patrick Duffy commissioned to have it transcribed onto a scroll by a calligrapher."In our community, there is a much-needed component of healing," said Duffy. "That's what this scroll and poem are essential and we hope is that it will help bring solace to others."The executive director of the LVMPD Foundation said he felt Fagel's words were a reminder of a kind of collective healing that's taken place in the year since the shooting."It was simply mind-blowing that someone could take such an awful tragedy and turn it into such a powerful reminder of the good that exists and the good that responded to that awful event," said Tom Kovach. "The Route" is on display in the lobby of LVMPD headquarters, which is open to the public. It will go on tour beginning in 2019.  1283

LAKE HUGHES, Calif. (CNS) - A fire burning near the Lake Hughes area is 12% contained Friday morning after scorching 11,000 acres and destroying three structures, authorities said.Firefighters, meanwhile, braced for dangerously hot weather caused by a heat wave this weekend."Near critical fire weather conditions could develop Friday afternoon and evening as gusty onshore winds could combine with warm and dry conditions in place," the Los Angeles County Fire Department reported Thursday.Crews were able to take advantage of improved fire weather conditions Thursday with slightly lower temperatures and moisture from the former hurricane Elida moving across the area, the department said."Current objectives include keeping the fire north of Castaic Lake, south of Highway 138, east of Red Rock Mountain and west of Tule Ridge," the department said.The fire was reported at about 3:30 p.m. Wednesday near North Lake Hughes Road and Pine Canyon Road in the Angeles National Forest and was 12% contained as of 7 a.m. Friday, according to the u. S. Forest Service, which was battling the blaze with Los Angeles County Fire Department crews and assistance from the Los Angeles, Culver City, Beverly Hills, Monterey Park, Long Beach and Santa Monica fire departments.The fire's size was listed as 11,000 acres Thursday night, with three structures destroyed and 5,420 threatened, according to the Los Angeles County Fire Department. No injuries have been reported."There have been areas of this fire that have not burned in decades, (and) it's in inaccessible terrain, which has added to the complexity of the fire," said Los Angeles County Fire Department Chief Daryl Osby.Although some structures were lost, a number of structures were saved by firefighters, he said."It's going to be a hot, dry summer -- and it's going to be a very, very hot, dry weekend," Osby said.On Wednesday, the fire west of Palmdale had a "rapid rate of spread," amid temperatures in the mid-90s, low humidity and gusty winds, according to the U.S. Forest Service. The forest service and county fire departments quickly called in second-alarm responses.The fire was entirely on federal land, according to the Los Angeles County Fire Department.Mandatory evacuations were ordered for the area east of Ridge Route Road, west of Lake Hughes Road, north of Pine Canyon Road and Lake Hughes Road, and south of state Route 138, said Los Angeles County sheriff's Capt. Ron Shaffer of the Palmdale Station.More than 100 structures were affected in the evacuation area, including primary residences and outbuildings, in the communities of Lake Hughes and Pine Canyon, officials said.Evacuation centers were set up for displaced residents at Highland High School in Palmdale and the Castaic Sports Complex."In this evacuation, unfortunately because of COVID protocols, a shelter is not actually established, people will have to stay in their cars," Shaffer said earlier. People staying in their cars at a center are allowed to have small animals with them.Animal boarding was made available at Castaic Animal Care Center, Lancaster Animal Care Center, Palmdale Animal Care Center and the Antelope Valley Fairgrounds, according to the American Red Cross Los Angeles.San Francisquito Canyon Road was closed from Stater Lane to Spunky Canyon Thursday evening, as well as Three Points Road from State Route 138 to Pine Canyon.More than 1,500 firefighters, along with three helicopters, five water tenders, and 173 engines, were assigned to the firefighting effort.The cause of the fire was under investigation. 3581

LA MESA (KGTV) -- It was a frustrating flight for one mother in La Mesa, who said an airline would not allow her to sit next to her toddler without forking over extra cash.Aliss, who declined to use her last name, said she chose seats together when she booked her ticket through a third-party website. Aliss and her son, Kai, were travelling from Providence, Rhode Island back to San Diego with a layover in Minneapolis. When she got to the airport in Providence, her seat on her Sun Country Airlines flight was not next to her child.“I would have never booked a flight where we couldn’t sit together,” Aliss said. She said her options were limited and that the representative with the airline said she could charge her a fee.“I can’t pay that. What else can we do? And she said, well for I can move you guys in a row front and back of each other. I said that doesn’t help my problem. He’s still not sitting next to me,” Aliss said. She said she told the airline representative not to charge her the money, but she was charged anyway. She said she did not get help from anyone with the airline, including the flight attendant. “She said no, you’re on your own. You’ll just have to argue with people,” Aliss said. Fortunately, a grandmother ended up giving up her seat so Aliss could sit with Kai. That was only the beginning of her problems. From Minneapolis to San Diego, Aliss’ flight was delayed. At first, it was only three hours.“No big deal,” she said. She tried keeping Kai entertained and saw many other parents in a similar situation. The three hour delay became much longer with passengers unclear on when they were going to leave. “It was confusing, frustrating,” Aliss said. She said they were promised 0 vouchers for the long delay. Aliss said their 3:10 p.m. flight finally left around 12:30 a.m. Team 10 contacted Sun Country Airlines, who apologized for what happened. In a statement, a spokesperson told Team 10: “This was not the level of service we aim to provide, as it is our policy that children always be seated with an adult on the itinerary at no cost. We have followed up with our airport staff on this error to ensure our policy is being carried out correctly. We have issued a full refund to the passenger for the fees incurred at the counter related to the seat assignment. We were also able to ensure two seats were assigned next to one another on her return flight. Our team has resent the 0 vouchers from the flight delay to the email we have on file, and we are adding an additional 0 voucher for the inconvenience.”Aliss said it was a lesson for her to be prepared and to, “be wise with who you spend your money with.” A few years ago, Congress passed the Families Flying Together act, which was supposed to keep parents and children together on planes. However, the Department of Transportation has yet to implement it.It's unclear if or when they will do so. Team 10 contacted the DOT’s media relations, but has yet to hear back. 2990

La política de armas ha sido un tema difícil por mucho tiempo, pero típicamente no ha sido un tema principal entre los votantes latinos hasta esta elección. Un estudio del Centro de Investigación Pew encontró que 7 de cada 10 votantes latinos quieren una legislación de armas más estricta. En El Paso, Texas, un tiroteo masivo que dejó 23 muertos y varios heridos ha provocado que la gente preste más atención a la política de armas y adopte una postura.Adrian Loera, quien vive en El Paso, practica su disparo frecuentemente. “Nunca se sabe cuándo va a pasar algo. Esa es una de las razones por las que obtuve mi licencia de arma de fuego, por los hechos que sucedieron aquí el a?o pasado ”, dijo Loera. Se refiere al 3 de agosto de 2019, cuando un hombre armado viajó cientos de millas hasta un Walmart en El Paso, con el único propósito de matar latinos. Loera dice que nunca había pensado en tener un arma. Ahora no solo tiene su arma, sino que también quiere asegurarse de que nadie le quite su derecho de portar un arma. Sus nuevas creencias podrían influir su voto en las próximas elecciones.El mismo evento horrible tuvo un impacto totalmente opuesto en Miranda Escobar Gregory. Mientras se para frente al nuevo memorial erigido para las 23 víctimas, recuerda el temor que sintió el día del tiroteo. Ella dice que toda la ciudad estuvo cerrada durante horas. "No es necesario tener una ametralladora gigante o una pistola semiautomática cuando se juega a lo seguro", dijo Escobar Gregory. Quiere que las armas de asalto estén prohibidas a nivel federal y una evaluación de salud mental sea parte del proceso de compra. En Texas, uno puede comprar un arma si pasa una verificación de antecedentes penales. Las solicitudes de licencia para portar armas han subido el último a?o en el estado de Texas.Quienes critican un proceso de compras más restrictivo dicen que hay otras tácticas que deben ser consideradas. "Otra ley que impida o intente evitar que los ciudadanos respetuosos de la ley tengan acceso no habría cambiado el resultado de ese día", dijo Richard García, director de entrenamiento de Sportsman Elite. García dice que es un defensor de la disminución de todos los tipos de violencia, pero siente que como país, debemos llegar al tema central de por qué siguen sucediendo estas cosas. “Creo que deberíamos avanzar hacia la raíz real del problema, que se remonta al individuo. ?Qué podemos aprender de la persona que hizo esto para evitar que algo así suceda en el futuro? ”, dijo García. García dice que se deben tener conversaciones para que podamos llegar a un compromiso. “Sé que no existe un compromiso perfecto, pero para eso están las leyes en los libros”, dijo García.Escobar Gregory dice que seguirá luchando por leyes de armas más estrictas y votará por quienes apoyen sus deseos. Mientras tanto, personas como Loera se apresuran a obtener una licencia para portar y comprar un arma, en temor de que les quiten el derecho de ser due?os de armas. 2982
