'Bagyong Hanna' has maximum sustained winds of 150 km/h near the center, gustiness of up to 185 km/h, and central pressure of 955 hPa. It is moving westward at 20 km/h. Strong to typhoon-force winds extend outwards up to 560 km from the center.


TCWS No.1 (Strong winds)
  • Batanes
  • the northern portion of Babuyan Islands


'Hanna' is forecast to continue moving generally westward until it makes landfall at or near peak intensity along the east coast of southern Taiwan this afternoon or evening.

Slight intensification shortly before landfall is not ruled out, although this window is quickly closing as the typhoon moves closer to land.

On the track forecast, the typhoon will cross the rugged terrain of southern Taiwan tonight, resulting in considerable weakening. 'Hanna' may emerge over the Taiwan Strait and exit the Philippine Area of Responsibility (PAR) this late evening or tomorrow early morning as a severe tropical storm.

Outside the PAR region, 'Hanna' will become slow-moving as it moves westward or west northwestward over the Taiwan Strait.

The weakening trend is forecast to continue after crossing Taiwan due to land interaction and increasingly unfavorable environment.

It is forecast to make its final landfall along the coast of Guangdong or Fujian, China on Tuesday as a tropical storm.

'Hanna' may weaken into a remnant low on late Wednesday or Thursday.


Forecast accumulated rainfall for today: 50-100 mm (Batanes)

The Southwest Monsoon currently enhanced by 'Hanna' will bring occasional to monsoon rains over the western portion of Luzon and Antique in the next three 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:

Today: 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.

Tomorrow: Batanes, Babuyan Islands, Ilocos Region, Abra, Benguet, Apayao, Nueva Vizcaya, Zambales, Pampanga, Bataan, Aurora, Bulacan, Metro Manila, CALABARZON, and most of Bicol Region, MIMAROPA, and Western Visayas.

Tuesday: Batanes, Babuyan Islands, Ilocos Region, Zambales, Bataan, Cavite, the northern portion of Quezon, Lubang Island, Romblon, and Kalayaan Islands.


Due to the combined influence of HANNA and the enhanced Southwest Monsoon, 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.

Disruption in civilian maritime activities is expected over these areas (e.g., suspension of sea travel) due to hazardous sea condition.
