Heat and humidity to grip New York City as another sweaty summer week kicks off
The National Weather Service issued a heat advisory for New York City on Monday and Tuesday that warned of heat index values up to 105 degrees Fahrenheit.
"These conditions are dangerous to health," the Notify NYC alert said. The people most at risk are those without air conditioning, people with chronic health conditions and people who work outside.
The heat will begin to build overnight Sunday into early Monday morning and will continue until at least Wednesday, with heat advisories in place for the next three days, the National Weather Service said in an area forecast discussion.
Heat advisories are also in place for New Jersey, Connecticut, Rhode Island and Massachusetts, the NWS said.
Heat indices in South Jersey, near Philadelphia, are expected to reach from 100-105 degrees Fahrenheit, with potential to be higher, a NWS area discussion from Mt. Holly, New Jersey, said.
Boston — also under a heat advisory — is expected to face heat indices in the mid to upper 90s, according to the NWS.
On Monday, the heat will seep into the south, too, with potential temperature records in Gainesville, Florida; Denver; New Orleans and Charlotte.
A cold front will move in Wednesday night, bringing with it possible showers, to break up the hot start to the week, the NWS discussion said.
In total, 123 million are under heat alerts through the first half of the week, with some alerts in effect through at least Wednesday.
The heat was taking hold over the Plains and Southeast U.S. Sunday, with conditions feeling like 110-115 degrees Fahrenheit.

Massive wildfire becomes California's largest blaze of the year
Rising temperatures are posing new challenges for firefighters who have made incremental progress against a massive wildfire in central California which has become the biggest blaze in the state so far this year. More than 870 remote homes and other structures at the northern edge of Los Padres National Forest are threatened by the Gifford Fire, which grew slightly overnight after burning out of control for days. The fire has scorched at least 131 square miles of Santa Barbara and San Luis Obispo counties, with just 9% containment. It surpassed the 126 square mile Madre Fire, which erupted last month in south-eastern San Luis Obispo County, as the state's largest fire of 2025. Crews working in steep, inaccessible terrain will be dealing with temperatures around 35C on Wednesday and above 38C on Thursday, said Captain Scott Safechuck with Santa Barbara County Fire Department. 'We have hot weather, and we have low relative humidity,' he said. 'So we expect extreme fire behaviour.' Luckily, winds are expected to remain relatively calm, he added. Wildfire risk will be elevated through the weekend across much of inland California as the heatwave intensifies. The southern part of the state has seen very little rain, drying out vegetation and making it 'ripe to burn', the National Weather Service for Los Angeles warned in a statement. Temperatures around 38C are forecast for the Sacramento Valley. More than 2,200 personnel are battling the Gifford Fire, which grew out of at least four smaller fires that erupted on Friday along State Route 166, forcing closures in both directions east of Santa Maria, a city of about 110,000 people. The causes of the fires are under investigation. Flames are racing through a vast, mostly unpopulated region that includes forests, ranches, large canyon properties and agricultural parcels growing wine grapes and strawberries. The weather service warned of health risks from spreading smoke that could affect much of south-west California. Officials reported four injuries, including a firefighter who was treated for dehydration. Over the weekend, a motorist was treated in hospital for burn injuries after getting out of his vehicle and being overrun by flames, and two contract employees assisting firefighters were hurt when their all-terrain vehicle overturned.
