The wildfires began accidentally when someone in Suffolk County tried to light a fire to make s’mores, officials said. They were fully contained by Monday.

Authorities say a series of brush fires that tore through the East End of Long Island over the weekend can now be traced back to one local backyard, where a family's attempt to make Saturday morning s'mores apparently went awry.

Gov. Kathy Hochul on Sunday announced an immediate "burn ban" for all of Long Island and New York City, and for parts of the Hudson Valley. The ban prohibits igniting any outdoor fires to remove brush or debris, as well any uncontained campfires or open fires for cooking.
