Suffolk County Fire, Rescue and Emergency Services Commissioner Rudy Sunderman said the fire will not be considered completely "contained" until 10-foot breaks are built around the full perimeter of the fire, where combustible materials and elements are removed to prevent it from reigniting and spreading.

There is an investigation into possible arson after firefighters knocked down the last of four wildfires that began in Suffolk County on Saturday. Those blazes prompted a State of Emergency, and on Sunday crews were working to prevent any further spread.

New York Gov. Kathy Hochul declared a state of emergency Saturday afternoon as dozens of fire departments responded to Long Island’s Pine Barrens to gain control of massive brush fires fueled by strong winds.
