40M Americans are under fire alerts after record-breaking heat triggered huge blazes across NJ

About 40 million Americans are threatened by fire as record-breaking heat has sparked fires in New Jersey and Wisconsin, while another 50 million are under severe weather warnings this weekend.

A massive wildfire has devastated nearly 1,000 acres of West Milford, New Jersey, leaving firefighters scrambling to contain the beast.

At 10 p.m. Saturday, the New Jersey Wildfire Department announced it had the fire “100 percent under control,” but there are fears more could break out.

Firefighters had been battling the blaze along Route 23 North and Spring Lake Road since earlier this week, and it’s not known how the monstrous blaze started. However, authorities said the unusually warm temperatures, dry vegetation and trees did not help prevent the fire from devastating much of New Jersey.

Emergency services used helicopters to drop water on the blaze and faced a dangerous situation Thursday night as embers flew off and sparked smaller blazes, but firefighters aren’t too worried.

“We have a lot of confidence in our steering lines. We will continue to mope, patrol and cut down all dead trees,” said Greg McLaughlin of the New Jersey Forest Fire Service. CBS news.
