A wildfire continued to burn into its second day on Sunday in Rockaway Township as the New Jersey Forest Fire Service worked to contain the blaze in the area of Farny State Park.The fire ignited just days after state officials had warned of "very high" fire risks throughout the state due to exceptionally dry weather, while the National Weather Service issued a similar warning on Friday.

"We don't see any relief in sight," NWS meteorologist Paul Fitzsimmons said of the ongoing dearth of rain. While he could not yet forecast when enough rainfall would wash over the region to improve conditions, he cautioned that the current drought is expected to continue for "a week or so."

As of midday, social media posts from the fire service's official account stated 30% of the Rockaway fire had been contained but that it continued to scorch brush across 77 acres near Jacobs Road.

State crews utilized helicopters to douse the blaze with 350 gallons of water on Saturday, while municipal fire departments from Morris County provided mutual aid to protect structures in the area, according to the service. On Sunday, 30 structures remained in peril due to the wildfire.

The Forest Fire Service continues to investigate what precisely ignited the Rockaway Township wildfire but spokesperson Caryn Shinske said her agency had no updates as of early Sunday afternoon.
