The Manila International Airport Authority (MIAA) temporarily suspended its operations following unfavorable weather conditions.

"The MIAA Airport Ground Operations and Safety Division (AGOSD) has issued a Red Lightning Alert at 11:45 AM / 1145H. Flight and ground operations are temporarily suspended," said MIAA in an advisory.

MIAA said that the red lightning alert is a "safety measure taken to prevent untoward incidents from happening when lightning is prevalent in the immediate area and may endanger personnel, passengers, and even flight operations."

A red lightning alert halts all ground operations and aircraft movements at the airport, including boarding, disembarkation, aircraft parking, baggage handling and all support activities.
