Major South Florida roadways remained closed on Thursday and around 200 residents evacuated as a brush fire in western Miami-Dade County burned thousands of acres and a second blaze worsened the smoky conditions.

Miami-Dade Fire Rescue officials said crews responded to the Quarry 2 Fire in the area of Northwest 137th Avenue and Northwest 25th Street on Monday as the fire grew.
That blaze continued to grow to around 15,900 acres and was 50% contained as of Wednesday night, according to the Florida Forest Service. A second fire, the Well Fire, has burned 500 acres and was 25% contained at last update on Tuesday.
The Florida Forest Service responded on Sunday after the fire originated from a thunderstorm and lightning strike, officials said.
At a news conference Wednesday afternoon, Miami-Dade Fire Rescue Chief Ray Jadallah said several hundred firefighters and staff members were working to contain the fire on the ground and by air.
Road closures
Miccosukee Police said Krome Avenue was shut down in both directions due to the brush fires that continued to burn and grow in size.
“Motorists are advised to avoid the area, expect delays, and seek alternate routes until further notice,” the department posted on X.
Pembroke Pines Police said Wednesday afternoon that U.S. Highway 27 southbound was also closed at Pines Boulevard due to the fire.
“No traffic can travel south on US-27 past Pines Blvd. Please avoid the area,” the department said on X.
The roadway reopened later Wednesday, police said.
Evacuations and the firefight
The Florida Forest Service was doing a backburn to try to cut off the vegetation that was fueling the fire but Jadallah said there was no timeline for when it could be extinguished.
“This fire obviously as big as it is, at some points has actually expanded to about three quarters of a mile wide as it burned,” Jadallah said.
Officials said Wednesday that around 200 residents of nearby Mack’s Fish Camp voluntarily evacuated and many were moved to a nearby fairgrounds while some went to live with family members. Some residents were encouraged to leave but chose to stay, officials said.

“No electricity. Can’t stay where there’s no electric; I need my air conditioning,” one resident, Lisa, said after leaving her home. “I packed my medicine, and my milk that’s going bad from the refrigerator that’s been off for four hours, and my tea, and here we are.”
A nearby business had been evacuated as a precaution on Monday, and aerial footage from Chopper 6 showed flames burning near a group of power lines and crews performing water drops from the air.
No injuries have been reported, but people with respiratory conditions in the area were advised to stay indoors and recirculate the air from their air conditioners.
Air quality improves
According to the AirNow Fire and Smoke Map, the air quality on Thursday had improved from unhealthy to moderate in the areas closest to the fire, including Miramar and Hialeah Gardens. This means more sensitive groups “should consider reducing outdoor activity” and go inside for cleaner air in the event of symptoms.
The smell of smoke had been consistent since the fires started, and some residents in western Broward County saw ash on their cars on Wednesday. Near the fires, thick smoke clouds the sky.

Temps could feel as high as 110 degrees Fahrenheit
A heat advisory will be in effect from noon until 7 p.m. in Broward, Miami-Dade and Monroe counties, the National Weather Service said. While not directly related to the fires, it makes the firefight more uncomfortable for first responders.
Officials said “heat indices up to 110° are possible, while wildfire smoke also continues to disperse from several local fires.”
Humidity also remains high, which helps rehydrate dry brush and makes it harder to burn. Still, the parched land could use rain; there’s a small chance for thunderstorms in the afternoon.
Meanwhile, the winds are forecast to stay light as they push north-northwest.
