One of the fires continued to burn late Monday afternoon along Waterloo Valley Road in Mount Olive Township.
This fire was not far from Route 46, I-80 and New Jersey Transit tracks, but no delays were immediately reported.
Firefighters tried to get water onto the flames by air because the area is difficult to reach by land.
Officials say the fire risk in the area is moderate, but the risk is expected to increase as the week goes on with the warmer temperatures.
