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.

Arson could be the cause of several wind-driven brush fires that burned on New York’s Long Island over the weekend, injuring two firefighters and sending large smoke plumes into the air, officials said.

An arson investigation is underway after a series of brush fires on Long Island in New York injured at least two firefighters as flames consumed hundreds of acres in Suffolk County over the weekend.

The last of four blazes that began in Suffolk County on Saturday has been put out, but Long Island and the Hudson Valley still faced a high fire risk on Sunday, officials said.

The brush fires were mostly contained by Sunday morning after burning about 600 acres, injuring two firefighters and prompting a state of emergency Saturday.

The state Division of Homeland Security and Emergency Services warned that wind gusts up to 40 mph were likely, complicating efforts to douse flames.
