MANILA -- (UPDATE) Some flights at the Ninoy Aquino International Airport were delayed on Sunday due to a red lightning advisory, its manager said.
The alert, which means lightning strikes "are prevalent in the immediate area and may endanger personnel, passenger, and even flight operations," was raised at 2:24 p.m., the Manila International Airport Authority (MIAA) said.
This prompted the suspension of ramp movement for both aircraft and personnel, it said.
The lightning alert was downgraded to yellow, which was lifted past 4 p.m., MIAA added.
As of 4:30 p.m., the following 19 flights were delayed, the agency said.
Last June 10, a red lightning alert also forced the suspension of ramp movement, leading to the delay of 54 flights and the diversion of 7 flights, MIAA records showed.
President Rodrigo Duterte made a surprise inspection at NAIA following the flight disruptions.
