A brush fire in Morris County has now burned for two consecutive days, threatening 30 homes in the area.

A total of 77 acres were already scorched in Rockaway Township.

First responders leading containment efforts said it was 30% contained on Saturday night and 70% contained as of Sunday evening.

They said dry conditions contributed to the fire.

"We are in one of the longest stretches of dry conditions for this time of year since 1863, so we are seeing unprecedented fuel conditions on the forest floor,” said Chris Franek, assistant division fire warden of the New Jersey Forest Fire Service. "We’re actually upping our campfire restrictions and burn bans tomorrow."

The glow of the fire lit up the night sky as crews worked as quickly and tactfully as they could.

First responders said they used hand lines, bull dozers and laid hoses around the edges to cool off hot spots near houses.

Jacobs Road remained closed as of Sunday evening. A drone was used to get a look from above while the containment efforts got underway.

A helicopter that can drop 350 gallons of water dropped 15 loads of water on the fire on Saturday afternoon.

A cause of the fire was not immediately known as of Sunday evening.
