MANILA, Philippines – Super Typhoon ‘Henry’ (international name: Hinnamnor) maintains strength as it moves southwestward over the Philippine Sea, state weather bureau PAGASA announced in its 5:00 am update on Thursday, September 1, 2022.
At 4:00 am today, the center of the eye of Super Typhoon ‘Henry’ was estimated based on all available data at 530 km East Northeast of Itbayat, Batanes.

‘Bagyong Henry’ has maximum sustained winds of 185 km/h near the center, gustiness of up to 230 km/h, and central pressure of 930 hPa. It is moving southwestward at 25 km/h.
Strong to typhoon-force winds extend outwards up to 340 km from the center.
Meanwhile, another weather disturbance Tropical Depression ‘Gardo’ was estimated based on all available data at 885 km East Northeast of Extreme Northern Luzon. It is unlikely to directly affect the weather condition in the country within the forecast period.
‘Gardo’ is expected to weaken into a Low Pressure Area within 12 hours or sooner as it merges itself with the larger circulation of Super Typhoon ‘Henry’.
TRACK AND INTENSITY OUTLOOK
‘Bagyong Henry’ is forecast to continue moving generally southwestward today through tomorrow early morning while decelerating.
By tonight or tomorrow early morning, the tropical cyclone may become almost stationary.
By midday of tomorrow, ‘Henry’ may begin tracking slowly northwestward before eventually accelerating northward by Saturday.
On the forecast track, it may exit the Philippine Area of Responsibility (PAR) on Saturday evening or Sunday morning.
PAGASA said ‘Henry’ has completed its eyewall replacement cycle. As such, this super typhoon may slightly re-intensify during the remaining time window before it enters its slowdown or quasi-stationary phase, when it is likely to begin weakening. Once it begins accelerating northward during the weekend, a slight re-intensification may still occur.
HAZARDS AFFECTING LAND AREAS
This late afternoon through evening: Light to moderate with at times heavy rains possible over Batanes.
Tomorrow: Moderate to heavy rains likely over Batanes and Babuyan Islands.
Saturday early morning through afternoon: Moderate to heavy rains possible over Batanes. Light to moderate with at times heavy rains possible over Babuyan Islands.
Under these conditions, isolated to scattered flooding (including flash floods) and rain-induced landslides are possible especially in areas that are highly or very highly susceptible to these hazard as identified in hazard maps, and in localities with significant antecedent rainfall.
This tropical cyclone is also forecast to enhance the Southwest Monsoon which may bring rains over the western section of Luzon beginning tomorrow. As such, the issuance of Weather Advisory for Southwest Monsoon is likely.
Due to the forecast expansion in the extent of tropical cyclone winds associated with Super Typhoon ‘Henry’, Tropical Cyclone Wind Signals (TCWS) may be hoisted for localities in Extreme Northern Luzon by today at the earliest in anticipation of potential strong breeze to near gale conditions. The potential for hoisting a Wind Signal No. 2 is also not ruled out.
HAZARDS AFFECTING COASTAL WATERS
Under the influence of Super Typhoon ‘Henry’, a Gale Warning is in effect for the northern and eastern seaboards of Northern Luzon. For more information, refer to Gale Warning #1 issued at 5:00 AM today.
In the next 24 hours, ‘Henry’ may bring moderate to rough seas over the eastern seaboard of Isabela (1.2 to 4.0 m). These conditions may be risky for those using small seacrafts. Mariners are advised to take precautionary measures when venturing out to sea and, if possible, avoid navigating in these conditions.
‘Henry’ is the Philippines’ eighth tropical cyclone for 2022.
On average, there are 20 tropical cyclones that could form or enter the Philippine Area of Responsibility each year. Only half of those are projected to make landfall.
