At 4:00 pm today, the center of Typhoon 'Hanna' was estimated based on all available data at 375 km East Northeast of Itbayat, Batanes.
'Bagyong Hanna' has maximum sustained winds of 140 km/h near the center, gustiness of up to 170 km/h, and central pressure of 965 hPa. It is moving west northwestward at 20 km/h. Strong to typhoon-force winds extend outwards up to 400 km from the center.
TROPICAL CYCLONE WIND SIGNALS (TCWS) IN EFFECT
TCWS No.1 (Strong winds)
TRACK AND INTENSITY OUTLOOK
'Hanna' is forecast to move west northwestward or westward while intensifying until it makes landfall along the east coast of southern Taiwan tomorrow afternoon or evening.
Considerable weakening is expected as a result of 'Hanna' crossing the rugged landmass of Taiwan.
On the forecast track, it will exit the Philippine Area of Responsibility (PAR) and emerge over the Taiwan Strait around Monday morning.
Outside the PAR region, 'Hanna' is forecast to move erratically and may even become slow-moving or almost stationary over the Taiwan Strait while continuously weakening due to land interaction and increasingly unfavorable environment.
By Wednesday or Thursday, 'Hanna' will have weakened into a tropical depression.
HAZARDS AFFECTING LAND AREAS
Forecast accumulated rainfall for tomorrow: 50-100 mm (Batanes)
The Southwest Monsoon currently enhanced by 'Hanna' will bring occasional to monsoon rains over the western portion of Luzon in the next three days.
The wind signals warn the public of the general wind threat over an area due to the tropical cyclone. Local winds may be slightly stronger/enhanced in coastal and upland/mountainous areas exposed to winds. Winds are less strong in areas sheltered from the prevailing wind direction.
Minimal to minor impacts from strong winds are also possible within any of the areas under Wind Signal No. 1.
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:
Today and tomorrow: Babuyan Islands, Ilocos Region, Cordillera Administrative Region, Nueva Vizcaya, Zambales, Pampanga, Bataan, Aurora, Bulacan, Metro Manila, CALABARZON, MIMAROPA, Bicol Region, Western Visayas, and the northern portion of Eastern Visayas.
Monday: Batanes, Babuyan Islands, Ilocos Region, Cordillera Administrative Region, Nueva Vizcaya, Zambales, Pampanga, Bataan, Aurora, Bulacan, Metro Manila, CALABARZON, and most of Bicol Region, MIMAROPA, and Western Visayas.
HAZARDS AFFECTING COASTAL WATERS
A Gale Warning is in effect for the northern and western seaboards of Luzon, the eastern seaboards of Central and Southern Luzon, portions of seaboards of Northern Quezon, the southern seaboard of Southern Luzon, and the western seaboard of Visayas due to the combined influence of 'Hanna' and the enhanced Southwest Monsoon.
Disruption in civilian maritime activities is expected over these areas (e.g., suspension of sea travel) due to hazardous sea condition.
TROPICAL CYCLONES
'Bagyong Hanna' is the eighth tropical cyclone for 2023. It entered PAR on Wednesday night.

On average, there are 20 tropical cyclones that could form or enter the PAR each year. Only half of those are projected to make landfall.
