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.

All four Long Island brush fires that sent soaring plumes of smoke into the air had been contained by Sunday afternoon, authorities said.

Officials stated that due to the wind conditions, the fire could persist for several hours, or even days, as the winds continue to ignite the blaze.
