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.

Boy, 13, dies after getting trapped in a storm drain during East Coast flooding
MOUNT AIRY, Md. (AP) — A 13-year-old boy died after he was trapped in a storm drain in Maryland during heavy rainfall and flooding on the East Coast, officials said. Kids were playing in the rain Thursday in a common area between apartment buildings in Mount Airy, a town of about 10,000 people about 30 miles (48 kilometers) west of Baltimore, but floodwaters rushed in and the boy was swept into the pipe, according to Mount Airy Volunteer Fire Company spokesman Doug Alexander. People tried to rescue the boy, but the water pressure was too strong and kept pushing him further into the pipe, he said. After the rain slowed, they were able to free him, but it was too late, Alexander said. More storms might bring flash and urban flooding to the northern mid-Atlantic and southern New England through Friday night, the National Weather Service warned. Parts of the Baltimore area received 2.5 to 4 inches (6 to 10 centimeters) Thursday, according to the weather service, but isolated areas received more, including 5 inches (nearly 13 centimeters) in Mount Airy and 6 inches (15 centimeters) in Joppatowne northeast of Baltimore, where people were rescued from flooded cars. A few areas in New York and New Jersey saw 3 inches (nearly 8 centimeters) or more of rain and one part of central Long Island reported more than 4 inches (10 centimeters), according to the weather service. By Friday morning, subways and commuter rail routes in the New York area were running on normal schedules after some sections were inundated by floodwaters. The city's Department of Transportation also reported that roads and highways that had been shut down due to high water Thursday were reopened. A few dozen flights were delayed or canceled at major airports in the New York, Boston and Washington regions Friday morning, but most were running on time, according to the FlightAware tracking service. Power remained out to thousands of homes and businesses along the Eastern Seaboard on Friday morning, including nearly 5,000 in New York, 3,800 in Virginia, 2,500 in Maryland and 2,500 in Pennsylvania, according to . Amtrak trains between Philadelphia and Wilmington, Delaware, were stopped Thursday evening because of high water over the tracks, but Amtrak announced a few hours later that service had been restored and water was receding from the tracks. New York City Mayor Eric Adams and other local officials pleaded with people Thursday to stay off the roads and urged residents in basement apartments to move to higher locations as rain was expected to fall through Friday afternoon.

How ‘fire clouds' caused by Arizona and Utah wildfires are creating their own erratic climate
Two wildfires burning in the western United States — including one that has become a 'megafire' on the North Rim of the Grand Canyon — are so hot that they are spurring the formation of 'fire clouds' that can create their own erratic weather systems. In Arizona, the wind-whipped wildfire that destroyed the Grand Canyon Lodge is 9% contained and has charred more than 164 square miles (424 square kilometers) to become the largest fire now burning in the continental U.S. and one of the top 10 largest in recorded Arizona history. Getting around it would be roughly like driving from New York City to Washington, D.C. Advertisement 7 Two wildfires burning in the western United States — including one that has become a 'megafire' on the North Rim of the Grand Canyon — are spurring the formation of 'fire clouds.' AP Another large fire in Monroe, Utah, has burned 75 square miles (194 square kilometers) since July 13 and is 11% contained, officials said Thursday. Evacuation orders were issued Wednesday for several towns in the fire's path, and scorched power poles caused electricity to be shut off in other nearby communities in south-central Utah. Utah Gov. Spencer Cox declared an emergency Thursday as wildfires grew around the state and planned to visit Monroe on Friday. Advertisement 'Fire clouds' present challenges for firefighters Towering convection clouds known as pyrocumulus clouds have been spotted over Arizona's blaze for seven consecutive days, fueling the fire with dry, powerful winds, fire information officer Lisa Jennings said. They form when air over the fire becomes superheated and rises in a large smoke column. The giant billowing clouds can be seen for hundreds of miles and can resemble an anvil.

AP Their more treacherous big brother, a fire-fueled thunderstorm known as the pyrocumulonimbus cloud, sent rapid winds shooting in all directions this week as a smoke column formed from the Utah fire then collapsed on itself, fire team information officer Jess Clark said. 'If they get high enough, they can also create downdrafts, and that's something we really watch out for because that can quickly spread the fire and can be very dangerous for firefighters who are doing their work on the ground,' Jennings said. Multiple fire crews in Utah were forced to retreat Wednesday as the unpredictable climate created by the clouds threatened their safety, officials said. Advertisement 7 Towering convection clouds known as pyrocumulus clouds have been spotted over Arizona's blaze for seven consecutive days. AP Fire crews in both Utah and Arizona had better control of the blazes, but containment has been slipping as the fires grow rapidly. The same type of cloud, which the National Aeronautics and Space Administration has dubbed the 'fire-breathing dragon of clouds,' recently formed a fire tornado that tore through an eastern Utah neighborhood with wind speeds estimated at 122 miles (196 kilometers) per hour. 'Think of the fire as kind of like a hot-air balloon, so it adds buoyancy and things rise as a result,' said Derek Mallia, an atmospheric scientist at the University of Utah who studies pyrocumulonimbus clouds and tracks fires in Utah and Arizona. 'You get this towering thunderstorm over the fire, and just like any other thunderstorm, it gets really windy underneath it. Because it's the West, these thunderstorms tend to be very dry.' These clouds, he said, may appear more frequently as climate change causes a longer fire season, drought conditions, and extreme weather events. Dry conditions fuel Grand Canyon 'megafire' A megafire — although not a formal scientific term — generally is a fire that has burned at least 156 square miles (404 square kilometers) — or about half the size of New York City. Advertisement The Dragon Bravo Fire on the North Rim of Grand Canyon National Park surpassed that mark in the latest update on Thursday. It was sparked by lightning on July 4 and is being managed by the park to benefit the landscape. About a week later, officials switched to suppressing it as conditions deteriorated, with hot, dry, and windy weather pushing the flames toward the Grand Canyon Lodge and the historic cabins that surround it. 7 The Monroe Canyon Fire blazes near Monroe, Utah, July 16. AP Advertisement The fire destroyed dozens of buildings and forced the closure of the North Rim for the rest of the season as hundreds of firefighters struggled to gain an upper hand. Thursday marked the eighth straight day of historically dry conditions, Jennings said. Humidity levels have been in the single digits, fuel moisture levels are extremely low, and wind gusts were expected to crank up to 35 miles per hour (54.7 kilometers per hour). The pyrocumulus clouds have reached heights of at least 25,000 feet (7,620 meters), and fire behavior analyst Arthur Gonzales said they could go higher. Advertisement 7 Multiple fire crews in Utah were forced to retreat Wednesday as the unpredictable climate created by the clouds threatened their safety, officials said. AP The direction of the wind has been fairly consistent for crews working the Dragon Bravo Fire. Although they have been strong, the predictability has allowed fire managers to more easily position crews on the fire lines. But when pyrocumulus clouds form and the winds become less predictable, Jennings said firefighters often have to be pulled back to safety. Advertisement Fire prompts power outages in Utah Hot, dry winds fanned the flames of the Monroe Canyon Fire on Thursday as firefighters worked to contain the spread. The fire has burned 12 power poles, and many homes have been without electricity since Wednesday afternoon. The National Weather Service issued red flag warnings for extreme fire danger in much of central and southwest Utah this week. In Antimony, Utah, 54 miles (87 kilometers) south of Monroe, the town's 123 residents were without power Thursday afternoon. Mayor Kasey King, who was helping people gather food and supplies at a community center, said they could be without power for a week. The power company, Garkane Energy Cooperative, said it is working to restore power as quickly as possible and has brought in backup generators. Marnie Reynolds, a resident of Antimony, worried for the town's many elderly residents. She has been using a camp stove to offer hot meals to neighbors and is using a generator to help people refrigerate groceries and medications. 'We have been facing a lot of challenges, but we have the best community,' she said. 7 Smoke and fires rise at sunset from the Dragon Bravo fire at the Grand Canyon as seen from Mather Point near Grand Canyon Village, Ariz., on July 28. AP 7 People take pictures in front of the 'fire clouds' at the Grand Canyon. AP In Richfield, Utah, 10 miles (16 kilometers) north of Monroe, Lee Stevens said his yard was coated in ash. He and his wife, who has asthma and is sensitive to the smoke, have not yet been told to evacuate but are making preparations in case the fire spreads. The National Interagency Fire Center said Thursday that even with fewer square miles having burned so far this year than average, many parts of the country remain vulnerable to new starts and fast-moving flames.
