Severe Tropical Storm Hanna intensifies as it decelerates westward over the Philippine Sea, Pagasa reported on its severe weather bulletin.
The center of the eye was estimated based on all available data 1,160 km East of Extreme Northern Luzon. It is moving Westward at 10 km/h with maximum sustained winds of 110 km/h near the center and gustiness of up to 135 km/h.
The Southwest Monsoon, currently enhanced by Super Typhoon SAOLA (GORING) (now outside the PAR) at this time is also being slightly enhanced by HANNA and Tropical Storm KIROGI (currently outside the PAR). The enhanced monsoon will bring occasional to monsoon rains over the western portions of Luzon in the next three days.
Forecast rainfall are generally higher in elevated or mountainous areas. Under these conditions, flooding and rain-induced landslides are expected especially in areas that are highly or very highly susceptible to these hazards as identified in hazard maps and in localities that experienced considerable amounts of rainfall for the past several days.
The enhanced Southwest Monsoon will continue to bring gusty conditions over the following areas not under any Wind Signal, especially in coastal and upland/mountainous areas exposed to winds:
Severe Tropical Storm Hanna intensifies
- Today and tomorrow: Ilocos Region, Cordillera Administrative Region, Zambales, Bataan, Aurora, Bulacan, Metro Manila, CALABARZON, MIMAROPA, Bicol Region, Western Visayas, and the northern portion of Eastern Visayas.
- Saturday: Zambales, Bataan, Bulacan, Aurora, Metro Manila, CALABARZON, MIMAROPA, Bicol Region, Western Visayas, and the northern portion of Eastern Visayas.
HANNA is forecast to accelerate west northwestward in the next 24 hours, then generally turn northwestward throughout the remaining forecast period. On the forecast track, this tropical cyclone will remain far from the Philippine landmass and may exit the Philippine Area of Responsibility (PAR) tomorrow while approaching the Ryukyu Islands.
Outside the PAR region, HANNA will continue to move over the East China Sea and make landfall over the east coast of mainland China on Sunday. Rapid weakening will ensue following its landfall over mainland China.
This tropical cyclone is forecast to gradually intensify until late Saturday or on early Sunday, when it is expected to reach its peak intensity. It may be upgraded into a typhoon within 24 hours while still inside the PAR region.
