Metro Manila (CNN Philippines, September 1) — Tropical Depression Gardo is about to merge with the broader circulation of Super Typhoon Henry, the state weather bureau said Thursday morning.
In its 5 a.m. bulletin, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Gardo will track northwest and turn west on east to northeast of the far north of Luzon where he will interact with Henry.
The interaction will weaken Gardo to an area of low pressure within 12 hours, the agency added.
The state meteorological office explained that Henry’s movement depends on two high pressure areas in Japan and China, which may slow its path in the northern part of the Philippines.
PAGASA also said he could raise Signal No. 2 over extreme northern Luzon as Henry maintained his strength and moved southwest over the Philippine Sea.
The super typhoon maintained maximum strong winds of 185 kilometers per hour and gusts of up to 230 km per hour near the center.
PAGASA said earlier that the merger of Gardo and Henry could also strengthen the southwest monsoon or “habagat” and trigger heavy rains over Luzon this week.
The Batanes will experience moderate to at times heavy rains while the Babuyan Islands will experience light to moderate rains with occasional heavy rains on Saturday, the state weather office said.
PAGASA also warned of flash floods and rain-induced landslides in localities with heavy rainfall.
Over the next 24 hours, the super typhoon could bring moderate to rough seas to the east coast of Isabela, which could be risky for those using small watercraft.
Henry should continue to move southwest while decelerating. PAGASA said the super typhoon could leave the weather watch area on Saturday evening or Sunday morning. It may slightly intensify again once it begins to accelerate northward over the weekend.
