By Sunday, firefighters had suppressed the flames and contained the blaze around roughly a quarter of its perimeter to prevent it from spreading, officials said at a news conference on Sunday. The wind gusts that fueled the flames on Saturday had slowed to 25 miles per hour on Sunday.But strong air currents combined with dry conditions in the Long Island Pine Barrens could yet pose a problem, said Lewis Scott, the second assistant chief of the Westhampton Beach Fire Department.“The weather is still a very significant concern and threat to us. We are hoping for some moisture to come in,” Chief Scott said at the news conference. “It’s not looking like that in the very near future.”Fire danger risk also remained high in the Hudson Valley on Sunday, according to the New York State Department of Environmental Conservation.The cause of the Long Island wildfire is still under investigation, the authorities said. Detectives from the Suffolk County Police Department have interviewed 911 callers, deployed drones and flown in helicopters to determine whether arson played a role.Wildfires periodically sweep through the Pine Barrens, an ecosystem that depends on fire in order to flourish. But the proliferation of the southern pine beetle, a species native to the southern United States that kills pines and leaves behind bone-dry tree bark, might have also contributed to the rapid spread of the fires this weekend.“There are dead trees all over because of them,” said Edward P. Romaine, the Suffolk County executive, who said thousands of trees in the area have succumbed to the insect over the last decade. “I am gravely concerned about the health and survival of the Pine Barrens as a result of that.”By Saturday evening, at least 600 firefighters and emergency service workers had extinguished three of the fires, and the Westhampton fire was 50 percent contained.Two structures were burned, and one firefighter had been hospitalized with second-degree burns to the face, Mr. Romaine said. Another firefighter suffered a head injury.An HH-60W Jolly Green II helicopter from the 106th Rescue Wing and three New York Army National Guard helicopters based in Ronkonkoma helped out with the response, the New York National Guard said in a news release.Fire trucks and crews from the Francis S. Gabreski Air National Guard Base in Westhampton Beach were also deployed. The base was evacuated as a precautionary measure, the National Guard said.Bill Dalton, a former chief of the Westhampton Beach Fire Department who was helping coordinate his department’s response, said several departments had deployed brush trucks, which are smaller fire trucks designed to fight wildfires.Drones were mobilized to get a bird’s-eye view of the fires, which stretched in a seven-mile radius in the area around Westhampton and Eastport on the South Shore.The New York State Police said on Saturday that all lanes of Sunrise Highway were closed eastbound between Exit 62 and Exit 64. County Road 31 southbound was also closed, according to the Southampton Police Department.By early Sunday morning, both roads had reopened, according to data from the state’s Department of Transportation.Gov. Kathy Hochul declared a state of emergency on Saturday afternoon, she said on social media. The National Weather Service had warned early on Saturday on social media that low humidity and northwest winds of 30 to 35 m.p.h. would create an “elevated risk for fire spread.”The fires dominated conversations on Saturday at the Quogue East Pub. Kieran Marsicovetere, 34, of East Quogue, said he saw heavy smoke and “a few ashes falling from the sky” early in the afternoon.The situation did not appear to be nearly as dire as brush fires that burned thousands of acres in the same area in 1995, he said. Still, he said, he was “immediately concerned.”“It’s a scary situation, especially with the wildfires in the Carolinas and California,” he said. “The Pine Barrens are always a concerning spot.”On Montauk Highway in Westhampton, police vehicles blocked roads leading to the Francis S. Gabreski Airport.Salvatore Fracapane, 19, watched live television coverage of the fires at his job at a convenience store nearby. He said he saw smoke and smelled “burning wood chips” around 1 p.m., then saw “fire trucks from everywhere” rushing to the scene.“I thought it was serious, seeing all those fire trucks out here,” he said.Amy Graff, Natalie Chandler, Simon J. Levien and Yan Zhuang contributed reporting.
