One fire burned on Tuesday afternoon along Route 7 in Kearny. Two more could be seen along the New Jersey Turnpike in Carlstadt, near the Vince Lombardi Rest Stop.
It's been a busy couple of days for firefighters in New Jersey.
Another brush fire burned Monday along Waterloo Valley Road in Mount Olive Township.
In that case, 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.
The fires were all put out by Tuesday evening.
