Super typhoon “Inday” (international name: Bavi) disrupted transportation and public services Saturday as airlines canceled international flights.

Likewise, nearly 1,000 passengers were stranded at seaports, even as several Metro Manila cities suspended classes.

Flood-control teams, meanwhile, worked to clear clogged drainage systems amid persistent heavy rains.

Philippine Airlines (PAL) canceled several international flights, affecting routes between Manila and Shanghai, Taipei, Busan, Nagoya, Fukuoka, Osaka and Tokyo, as well as the Cebu-Tokyo service.

The airline advised affected passengers to regularly check their flight status and coordinate with PAL for rebooking and other travel arrangements as aviation authorities continued to monitor weather conditions.

Maritime travel also remained heavily affected.

The Philippine Coast Guard (PCG) said 997 passengers, truck drivers and cargo helpers were stranded at ports across the country as of early Saturday after rough seas forced the suspension of vessel operations.

According to the PCG’s latest maritime safety advisory, 62 ports in Southern Tagalog, Northwestern Luzon, Northeastern Luzon, Palawan, Bicol, Western Visayas, Central Visayas, Southern Visayas and the Bangsamoro Autonomous Region in Muslim Mindanao were affected.

The weather also prevented 261 rolling cargoes, 12 vessels and 33 motor bancas from sailing, while 162 vessels and 151 motor bancas sought shelter in safe anchorage to avoid strong winds and rough seas.

Southern Tagalog recorded the highest number of stranded passengers with 272, followed by Western Visayas with 253 and Central Visayas with 186.

The coast guard urged travelers to coordinate with shipping lines and local port authorities for updated sailing schedules.

In Metro Manila, local governments suspended classes because of heavy rainfall brought by the enhanced southwest monsoon intensified by “Inday.”

Manila canceled classes in all public and private colleges Saturday after the Manila Disaster Risk Reduction and Management Office warned that rainfall could reach 50 to 100 millimeters, raising the risk of flooding and hazardous travel conditions.

Caloocan and Malabon also suspended face-to-face classes at all levels, shifting instruction to online learning.

Meanwhile, the Metropolitan Manila Development Authority (MMDA)deployed its Flood Control Team to conduct declogging and clearing operations in flood-prone areas of Quezon City.

Personnel manually removed garbage that had accumulated in drainage inlets and waterways to improve water flow and reduce flooding.

The MMDA also appealed to the public to stop throwing garbage into streets and esteros, saying improperly discarded waste continues to clog drainage systems and worsen flooding during heavy rains.

Weather authorities warned that heavy rains associated with Inday and the enhanced southwest monsoon could continue over parts of Luzon, prompting government agencies to remain on alert for possible flooding and other weather-related emergencies.
