A rare and terrifying phenomenon known as a “firenado” was recently observed during the ongoing brush fires in Miami-Dade County. A tornado-like vortex of smoke and flames was captured on video, drawing attention to this unusual weather event.
Firenadoes, also called fire whirls, are spinning columns of hot air and gases that rise from intense fires. They can vary in size, ranging from less than one foot to over 500 feet in diameter, and are characterized by their ability to lift and transport smoke, debris, and flames.
What causes a firenado?
The formation of a firenado requires specific conditions, including intense heat from a fire, strong updrafts, air convergence, and the presence of wind shear. The process begins when the extreme heat from a wildfire causes air to rise rapidly, creating a low-pressure zone at its base. This low pressure then draws in surrounding cooler air, initiating a swirling motion.
The terrifying Miami-Dade tornado makes a whirl
What makes the Miami-Dade firenado particularly noteworthy is its size and duration. The firenado by the Florida Kays brush fires was particularly large and persistent.
Firenadoes pose a significant threat during wildfires due to their unpredictable nature and intense heat. They can spread flames rapidly and cause extensive damage, making them a serious concern for firefighters and nearby communities.
