Severe thunderstorm watch issued May 5 for Treasure Coast, as hail pelts some areas
'We currently have a severe thunderstorm watch in effect for Martin, St. Lucie and Indian River counties until 9 p.m. for severe thunderstorms capable of producing damaging winds possibly up to 50 to 70 mph and hail up to 2 inches,' said meteorologist Robert Haley.
Along with rain in the afternoon in Vero Beach, Fort Pierce and southern Martin County around Port Salerno, dime-sized hail bounced on vehicles, outdoor furniture and concrete.
The storm system is expected to bring scattered heavy rainfall that may cause drainage flooding and 'deadly cloud-to-ground lightning.'
'These storms are expected to develop along the sea breeze as it pushes inland,' he said, which are then expected to push back over the Treasure Coast into the early evening.
'There's going to be two rounds for the Treasure Coast counties: The first one is happening right now and then that activity will push inland,' Haley said. 'But then we expect it to move back towards the coast later this evening.'
That second push could happen around 8 p.m., depending on location, he said.

'It's actually not too different from the summertime afternoon thunderstorms where everything is just driven by chaotic boundary interactions and you just have to watch and see how things form and how things evolve,' he said.
'The extra ingredients that are going on (May 5) is the upper levels are more supportive of stronger thunderstorms than we typically see in the summer time so that's where the hail threat and the stronger wind threat is coming from.'

The tri-county area should be free of thunderstorms by midnight he said.
There's a slight chance for more scattered showers on May 6, he said.
'The severe threat does not continue into (May 6,)' he said. 'Just some showers and thunderstorms possible.'

Tsunami Advisory canceled for Oregon Coast Wednesday morning
PORTLAND, Ore. (KOIN) — A Tsunami Advisory was removed for the Oregon and Washington coasts Wednesday morning after an 8.8 magnitude earthquake struck off the coast of Russia Tuesday night. Just after 10:30 a.m. Wednesday, the National Weather Service said that the Tsunami Advisory was no longer in effect. Emergency management officials say the largest waves were recorded at two feet off the Oregon Coast around 11:50 p.m. Tuesday. But while the coast is clear for a tsunami, officials say hazardous conditions could linger for several days — adding that even the strongest swimmers could struggle in the strong waters. 'There is still tsunami water that is hitting the coast, and those waves are stronger, and the currents are going to be a little different than they're used to, and there's also going to be a lot of debris in the water, so logs and other things like that,' Erin Zysett with OEM said. 'They can roll on you, you can get pinned, high tide comes in, and it can be very terrifying and very dangerous.' Old Farmer's Almanac reveals prediction for Pacific Northwest's fall season Tsunamis can also amplify the effects of sneaker waves, so you should never turn your back on the water. 'People should stay away from open coast beaches, estuary mouths, marinas, and harbors. Dangerous currents are possible even without significant wave activity,' officials with the Oregon Department of Geology and Minerals said in a statement. 'Do not go to the beach to watch the waves. Remain in a safe location away from the coast until the advisory is lifted.' Officials say the scare serves as a reminder for people to sign up for local alerts and familiarize themselves with the tsunami warning levels and nearby evacuation routes.

After a generally mild start to summer, August is bringing triple digit temperatures
After a month of relatively mild summer temperatures across much of Southern California, Mother Nature is turning up the heat next week. Temperatures this weekend will hover in the mid-80s in downtown Los Angeles, and the high 80s to mid-90s in the valleys and persist through at least Monday, according to the National Weather Service. The low clouds and morning fog that hang along the coast and burns off by the early afternoon is also expected to continue. But not for long. The mercury is forecast to rise on Tuesday, and by Wednesday it'll be extra toasty across much of Los Angeles County with temperatures soaring past 100 degrees in the valleys and the low 80s along the coast, said Mike Wofford, a meteorologist with the National Weather Service, in Oxnard. Read more: City by the Bay? More like City by the Brrr! San Francisco is having its coldest summer in decades "We're not looking at temperatures like we've seen in some previous summers, where we've gotten to 120 degrees, but it's certainly looking like 5 to 10 degrees above normal," Wofford said. Downtown Los Angeles could experience temperatures in the mid-90s by the middle of next week. Woodland Hills is forecast to get up to about 107 degrees and Burbank could get up to about 100 degrees, according to the weather service. Over the last few weeks a persistent low pressure system has been lingering in the Pacific Northwest and British Columbia which has kept temperatures cooler across much of California. But next week a high pressure system will expand from New Mexico and Arizona toward the west coast bringing a significant warm up. "We definitely had a pretty quiet July. We had some warm temperatures in June there for a bit, but July was pretty blah in terms of temperatures," Wofford said. Widespread strong winds are not expected to accompany next week's warm up, reducing the risk of serious fire weather conditions, Wofford said. But it's still early in the fire season, experts warn. With heat waves likely continuing through the rest of the summer, drying out brush, and later fall winds kicking up, it could make for dangerous conditions in the coming months. As temperatures rise, officials caution the public to stay hydrated, avoid strenuous outdoor activities and check on those who are vulnerable to heat-related illnesses. On Wednesday, a 21-year-old hiker collapsed from possible heat stroke while hiking on a trail near Lake Berryessa. Another six hikers were also suffering from heat related illness and had to be rescued, according to the Vacaville Fire District. "Take HEAT seriously," the fire district warned in a post on Instagram. "This could have been deadly." Sign up for Essential California for news, features and recommendations from the L.A.

Wildfire Threat Hits Hawaii as Pacific Hurricane Season Takes Off
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Meteorologists warned of an increased wildfire threat across Hawaii on Friday as strong winds begin to blow across the state, much of which is battling drought. Why It Matters Hawaii entered a period of heightened wildfire risk on Friday as the National Weather Service (NWS) issued a red flag warning for all leeward areas and interior sections of the islands. The warning signaled the potential for extreme fire behavior driven by strong winds and low humidity and comes in the middle of the Pacific hurricane season, which has already seen an active start. Wildfires pose a serious threat to Hawaii's communities, native ecosystems, drinking water, infrastructure, and cultural resources, as evidenced by the destructive Maui fires in 2023, which were fueled by strong winds. What To Know The NWS in Honolulu announced a red flag warning for all Hawaiian Islands, effective through 6 p.m. local time on Friday, due to a combination of dry conditions, strong easterly trade winds, and low relative humidity. The warning covered leeward portions of all islands and interior sections on the Big Island, listing expected wind speeds of 15 to 30 miles per hour with gusts up to 40 mph on Oahu and Kauai, and gusts as high as 50 mph in Maui County and the Big Island. Relative humidity levels were expected to drop as low as 35 to 45 percent in the afternoon, meaning the landscape would be increasingly susceptible to ignition. Residents were urged to avoid outdoor burning, refrain from parking vehicles on dry grass, and delay spark-producing activities until calmer conditions returned. The NWS's red flag warning comes as the National Hurricane Center (NHC) monitors four disturbances, including two tropical storms, Iona and Gil. Iona passed well south of Hawaii earlier this week, and although some of the winds in Hawaii were driven by the tropical systems passing south of Hawaii, AccuWeather lead hurricane expert Alex DaSilva told Newsweek an area of high pressure north of the islands is the primary driver behind the winds, similar to what happened in 2023. "These tropical systems that have gone by, like helped a little bit with some of the winds, but it's a similar two years ago when they had the wildfires in Maui," DaSilva said. "Everybody was really jumping on Hurricane while [Dora] played some role, [the winds] were caused by high pressure north of the island. Unusually strong trade winds really picked up around that high pressure, and that's what led to that event two years ago." DaSilva added that Hawaii is facing a similar setup now, although the trade winds won't be as strong. "We have a similar situation with these storms coming underneath Hawaii and strong high pressure to the north, but it's not nearly as strong as what happened two years ago," he said. "But winds are going to be strong enough through the weekend where there definitely can be some wildfire risk because it's so dry." Wildfires burn over the town of Lahaina as seen in the neighboring Kaanapali Alii resort, on August 08, 2023, in Maui.

Gonzalo Marroquin/Getty What People Are Saying NWS Honolulu in a red flag warning: "A combination of strong winds, low relative humidity, and dry fuels can contribute to extreme fire behavior. Any fires that develop will likely spread rapidly. A Red Flag Warning does not predict new fire starts." It added: "Heat from vehicle exhaust systems can ignite dry grass. Park cars on areas that are paved or where vegetation is trimmed and cleared. High winds contribute to wildfire hazard. Delay activities that could throw off sparks until the wind dies down." What Happens Next? Officials and emergency agencies urged Hawaii's residents and visitors to remain vigilant, continue monitoring official weather updates, and take preventive measures seriously. DaSilva said strong winds will persist in Hawaii through the weekend before they start to die down early next week.
