Is Orlando Airport open? Flights temporarily stopped at US airport after cold weather triggers false fire alarm
Flights were temporarily grounded at Orlando International Airport on Sunday after a false fire alarm was triggered.
The incident, which began around 3:30 p.m., led to the precautionary evacuation of tower staff and a temporary FAA-issued ground stop on departures. Airport officials quickly clarified that there was no actual fire or emergency.
Orlando International Airport Fire Rescue (ARFF) responded promptly and determined the alarm was triggered by a sprinkler head. The fitting activated due to unusually cold temperatures affecting the tower’s water system.
Freezing conditions in Central Florida caused the sprinkler to discharge, setting off the alarm and prompting an abundance-of-caution evacuation of air traffic controllers. The Federal Aviation Administration (FAA) halted departures as a safety measure while the situation was investigated, resulting in a ground stop that lasted approximately 45 minutes.
The stop was lifted around 4:15 p.m., and flight operations resumed gradually with no reported injuries, damage, or ongoing hazards. An airport spokesperson emphasized the false nature of the alarm, attributing it entirely to weather-related infrastructure vulnerability.
No passengers were evacuated from terminals or aircraft, and the event remained confined to the control tower. The brief interruption caused some flight delays and cancellations, though the impact was limited compared to MCO’s typical high volume of traffic. Orlando is Florida’s busiest airport, serving millions of passengers annually.
