Multiple Los Angeles County Fire Department helicopters were called in to assist with hikers experiencing medical emergencies Sunday.
The first incident was reported shortly before noon on Placerita Canyon Road in Newhall, with the second reported just minutes later shortly after noon on The Old Road in Newhall in the Towsley Canyon area, according to Fire Department Supervisor Miguel Ornelas.
Both helicopters were called in to assist in locating the hikers whose injuries were unknown.
At least one person was airlifted to the hospital as a result of the Placerita Canyon incident, per fire officials.
Two more patients were airlifted in the Towsley incident and were dropped off at the entrance to the hiking area, one of whom was then transported to the hospital via ambulance.
An extreme heat warning was in effect in the Santa Clarita Valley from Saturday until Tuesday, with temperatures in the triple digits.
Park rangers and Los Angeles County Department of Public Health officials advise hikers to take precautions to avoid heat-related illnesses, such as drinking plenty of fluids and trying to limit physical activity to the morning or evenings, avoiding peak heat times.
After the peak of the heat spell, SCV residents should expect temperatures to remain at or below 100 degrees through next week, according to National Weather Service meteorologist Mike Wofford.
