SAN FRANCISCO (AP) — The amount of snow blanketing the Sierra Nevada is even larger than the 2017 snowpack that pulled the state out of a five-year drought, California water officials said.As of Thursday, the snowpack measured 202% of average after a barrage of storms throughout winter and spring, according to the Department of Water Resources.The wet weather has slowed but not stopped, with thunderstorms prompting flash flood warnings Sunday in the central and southern parts of the state.At this time last year, the snowpack measured 6% of average — making this year 33 times bigger than 2018, the San Francisco Chronicle reported.In 2017, the snowpack measured 190% of average.The snowpack supplies about 30 percent of state water needs.In the Tahoe Basin, Squaw Valley ski resort has seen so much snow it plans to keep its slopes open until least July 5. In May alone, Squaw recorded 37 inches (94 centimeters).State officials consider the most important snowpack measurement to be the one taken around April 1 because that's typically when storm activity subsides."And then after that the sun's highest position in the sky contributes to rapid melting. This year, that didn't happen and we had late season snow," National Weather Service forecaster Idamis Del Valle told the newspaper.This year's April 1 reading put the snowpack at 176% of average, making it the fifth-largest on that date, with records going back to 1950, the Chronicle said.___Information from: San Francisco Chronicle, http://www.sfgate.com 1528

SARASOTA, Fla. — A Florida woman says she fell ill with COVID-19 and passed the coronavirus onto her 99-year-old mother who lives with her.Ruta Jouniari said she felt sick in October. She had a fever, cough and headache."I literally couldn't breathe. I tried to take a breath and the pain in my lungs was so incredible," she said.Jouniari was hospitalized at Sarasota Memorial Hospital for three days, but did not need oxygen."The nights were horrific, you have night sweats, shivering. You're achy. You can't breathe," she said.Her mother, who Jouniari is the primary caregiver of in her home, later tested positive for COVID-19.Jouniari said her mother never left the house, so she knows she brought the virus home, but she doesn't know where she contracted it.Her mother's age put her at a high risk of contracting the virus. Her mother, she added, suffered from a stroke about seven years ago."The guilt trip that goes with a child giving their parent COVID is not a fun reality of life," she said.Jouniari said her mother was hospitalized for 10 days. She was on a ventilator in an intensive care unit. Doctors treated her mother with plasma, remdesivir and dexamethasone."Going in, it's so frightening and you're so scared and you're scared for yourself when you're the patient, but you're even more scared knowing the statistics of a 99-year-old going in," said Jouniari.Jouniari said her mother left the hospital on Monday."For her to come out and come home today and she's in her own room, her own bed, breathing on two liters of oxygen. It's just amazing," she said.She urges everyone to take precautions and protect the vulnerable population."I hate to say this, but you could kill them. I was witness to that. I could have. My mom is a miracle of miracles. She's a statistic anomaly. She shouldn't have made it and she did," said Jouniari.She said she appreciates everyone who prayed for her mother. She said she is also thankful for the doctors and nurses who cared for her mother."I had over 800 people praying for her and it was incredible...the power of that was just amazing," Jouniari said. "For those families who are suffering, I hope they have solace and peace, just pray hard and have faith just know that people at 99 make it out. She is a testament to that."This story was originally published by Julie Salomone at WFTS. 2352

SEATTLE (AP) — U.S. scientists said Friday they will investigate why an unusual number of gray whales are washing up dead on West Coast beaches.About 70 whales have been found dead so far this year on the coasts of California, Oregon, Washington and Alaska, the most since 2000. About five more have been discovered on British Columbia beaches. That's a very small fraction of the total number of whales believed to have died, because most simply sink and others wash up in such remote areas they're not recorded.NOAA Fisheries on Friday declared the die-off an "unusual mortality event," providing additional resources to respond to the deaths and triggering the investigation."Many of the whales have been skinny and malnourished, and that suggests they may not have gotten enough to eat during their last feeding season in the Arctic," agency spokesman Michael Milstein told reporters during a conference call.The eastern North Pacific gray whales were removed from the endangered species list in 1994, after recovering from the whaling era.The population has grown significantly in the last decade and is now estimated at 27,000 — the highest since surveys began in 1967. That has raised questions about whether their population has reached the limit of what the environment can sustain. Another theory suggests that the loss of Arctic sea ice due to global warming is a culprit.The whales spend their summers feeding in the Arctic before migrating 10,000 miles (16,000 km) to winter off Mexico. Though they eat all along their route, they are typically thinning by the time they return north along the West Coast each spring.They eat many things, but especially amphipods, tiny shrimp-like creatures that live in sediment on the ocean floor in the Arctic. For many years, researchers noted that fewer calves tended to be born following years when the ice in the Chukchi Sea, north of the Bering Strait between Alaska and Russia, was late to melt. The whales had less time to feast because they couldn't access the feeding area, and thus had less blubber to sustain them on their next migration.Last year, though, the Artic was unusually warm. The whales weren't blocked from the feeding area, and yet are still struggling this year. That has scientists wondering if the loss of sea ice has led to a loss of algae that feed the amphipods. Surveys show the amphipod beds moving farther north, said Sue Moore, a biological oceanographer at the University of Washington."The sea ice has been changing very quickly over the last decade or so," she said. "The whales may have to shift to other prey, such as krill or other things they eat."In an average year, about 35 whales wash up in the U.S.In 2000, more than 100 did, prompting NOAA to declare an "unusual mortality event" then as well. The resulting investigation failed to identify a cause. The die-off followed strong changes in ocean conditions in the mid-1990s, suggesting that warmer water patterns affected the availability of prey, but scientists were often unable to perform necropsies, Moore said."It's sometimes very difficult to get to these whales in a timely fashion," she said. "You can't always get the kind of samples you would need for diagnostic reasons."Since then, researchers have built up an improved network of volunteers and have better educated the public to help report and respond to whale deaths, said Deborah Fauquier, veterinary medical officer at NOAA's Office of Protected Resources. This time around, scientists have been able to perform necropsies on 20 of the whales, she said.John Calambokidis, a research biologist with the Cascadia Research Collective, noted that as the whales search farther afield for food, they've entered areas where they're not normally seen so often, including San Francisco Bay and Puget Sound. That puts them at higher risk of being struck by ships or entangled in fishing gear.Four of the 10 gray whales found dead near San Francisco this year were struck by ships, and a number of shipping companies have slowed their vessels in the area to avoid collisions. 4086

Sen. John McCain's wife, Cindy McCain, and daughter, Meghan McCain, released poignant statements of thanks and remembrances Saturday evening just after it was announced that the Arizona Republican, 81, had passed away at h

Scientists have discovered a pocket sized dinosaur forerunner that was just 4 inches tall. Named Kongonaphon kely, which means tiny bug slayer, the creature looked like a dinosaur but scampered the Earth earlier, predating both dinosaurs and flying pterosaurs. The fossils, dug up in Madagascar, date from 237 million years ago, according to a study Monday in the journal Proceedings of the National Academy of Sciences. 429
