Light to heavy rain may continue in the Ilocos Region, Cordillera Administrative Region, Cagayan Valley, and Central Luzon until Wednesday morning, October 13

Severe Tropical Storm Maring (Kompasu) left the Philippine Area of Responsibility (PAR) at 11 am on Tuesday, October 12, but its effects continued to be felt in the country even after its exit.

The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said in a briefing past 5 pm on Tuesday that Maring was already 505 kilometers west of Calayan, Cagayan.

The severe tropical storm accelerated over the West Philippine Sea, now moving west at 30 kilometers per hour from the previous 20 km/h.

It still has maximum sustained winds of 100 km/h and gustiness of up to 125 km/h. (READ: FAST FACTS: Tropical cyclones, rainfall advisories)

Maring had made landfall in Cagayan’s Fuga Island at 8:10 pm on Monday, October 11. It caused floods and landslides in parts of Cagayan Valley, the Ilocos Region, and the Cordillera Administrative Region (CAR).

From Tuesday evening to Wednesday morning, October 13, light to heavy rain is likely to persist in these regions:

  • Ilocos Region
  • Cordillera Administrative Region

  • Visayas
  • Zamboanga del Norte

There are no more storm surge warnings in place, but sea travel remains dangerous.

Maring is the Philippines’ 13th tropical cyclone for 2021 and the second for October.

On Sunday morning, October 10, Maring had completed its merger with the remnant low that was formerly Tropical Depression Nando. The two tropical cyclones had interacted over the Philippine Sea, resulting in the merger.

Nando, the Philippines’ 14th tropical cyclone for 2021, had no impact on weather in the country.

An average of 20 tropical cyclones form within or enter PAR each year. (READ: LIST: PAGASA’s names for tropical cyclones in 2021)
