Supertyphoon Hinnamnor is likely to enter the Philippine area of responsibility (PAR) by evening Wednesday or early Thursday morning based on the track and intensity forecast of the state weather bureau.

In its 5AM weather bulletin, the Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa) said based on the latest track of Hinnamnor — which will be named “Henry” once it reaches PAR — was last located 1,305 kilometers east-northeast of extreme northern Luzon, packing maximum sustained winds of 195 kph with gustiness up to 240 kph.

“Hinnamnor may reach a peak intensity of 205 kph within 24 hours before gradually weakening as it enters its quasi-stationary phase. This tropical cyclone may be downgraded to typhoon category by Friday,” Pagasa said in its advisory.

This means that the weather disturbance will have a bigger diameter in Pagasa’s monitoring instruments, and will have an effect of increased possibility of raising a tropical cyclone wind signal over the area of extreme northern Luzon, such as Batanes and Babuyan Islands.

Light to moderate rains to sometimes heavy rains with isolated thunderstorms may also be expected by late Thursday or Friday as Hinnamnor enhances the southwest monsoon or “habagat” in a large swathe of western Luzon, including Metro Manila.

While Pagasa said that Hinnamnor may not make a landfall in any part of the country, it will still dump huge volumes of rainfall in extreme northern Luzon and Luzon, causing floods and landslides.

Meanwhile, Pagasa is also monitoring Tropical Depression Gardo, which was last seen moving north-northwestward as it interacts with Hinnamnor. The two weather systems so far has no direct effect but may likely induce habagat rains.

Dubbed by Washington Post as a “rare supertyphoon” and a “powerhouse storm,” it said Hinnamnor was 2022’s strongest typhoon to date, the equivalent of a Category 5 Hurricane in the United States.

Pagasa has six classifications for tropical cyclones, and while Hinnamor is still categorized as a typhoon as it moves towards PAR, it already packs a maximum wind speed of 195 kph.

A typhoon has a maximum wind speed of 118 to 184 kph, while a supertyphoon has maximum wind speed exceeding 185 kph.
