Severe Tropical Storm Maring (Kompasu), which continues to trigger heavy rain in Northern Luzon, slightly intensified as it moved over the West Philippine Sea before dawn on Tuesday, October 12.
Maring now has maximum sustained winds of 100 kilometers per hour from the previous 95 km/h, while its gustiness is up to 125 km/h, said the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA).
The severe tropical storm was last spotted 170 kilometers west of Calayan, Cagayan, moving west at 20 km/h.
It had made landfall in Cagayan’s Fuga Island at 8:10 pm on Monday, October 11. (READ: FAST FACTS: Tropical cyclones, rainfall advisories)

The weather bureau also reiterated that there is a “minimal to moderate risk” of life-threatening storm surges up to 1 meter high on Tuesday.
“Rising seawater along with the high waves from the shoreline moving inland may cause flooding in the low-lying coastal localities of Batanes, northern Cagayan including Babuyan Islands, and Ilocos Norte,” it said.
It remains dangerous to travel by sea.
Rough to high seas (waves 2.8 to 7.5 meters high)
Conditions risky for all vessels
- seaboards of areas under Signal Nos. 1 and 2
Rough to very rough seas (waves 2.8 to 4.5 meters high)
Small vessels advised not to sail, larger vessels alerted against big waves
- western seaboard of Central Luzon (not under a tropical cyclone wind signal)
- seaboards of Southern Luzon and Visayas
- western, eastern, and northern seaboards of Mindanao
Moderate to rough seas (waves 1.2 to 2.5 meters high)
Conditions risky for small vessels
- remaining seaboards of the country
Maring may exit the Philippine Area of Responsibility (PAR) on Tuesday morning or afternoon.
After leaving PAR, it will head west for Hainan, China, where it could make landfall on Wednesday evening, October 13.
PAGASA said Maring is projected to gradually strengthen within the next 36 hours, but it is “becoming less likely to reach typhoon category” prior to its possible landfall in Hainan.
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)
These are PAGASA’s latest estimates for the next six months:
- October – 2 or 3
- November – 2 or 3
- December – 1 or 2
- January – 0 or 1
- February – 0 or 1
- March – 0 or 1
The weather bureau is also monitoring the possible emergence of La Niña in the fourth quarter of 2021. – Rappler.com
