Issued at: 1:30 PM PhT (05:30 GMT) Wednesday 19 August 2015
Next Update: Wednesday Evening, 19 August 2015

Typhoon GONI (INENG) decreases further its forward speed while maintaining its westerly track. This strong tropical cyclone is likely to directly affect Extreme Northern Luzon...particularly the Batanes Group of Islands on Friday and Saturday (Aug 21-22).

Meanwhile, ATSANI (17W) has intensified into a Super Typhoon (STY) as it continues to move northwest over the warm waters of Northwest Pacific. At 11:00 am today, the eye of Typhoon ATSANI (17W) was located some 1,015 km northeast of Guam or about 1,820 km from the eastern border of the Philippine Area of Responsibility (PAR) (19.0N 152.3E)... with maximum sustained winds of 220 kph near the center and gustiness up to 280 kph. It is forecast to continue moving Northwest at a slower forward speed of 17 kph. ATSANI is not a threat to the Philippine Islands as none of the Global Dynamic Forecast Models show a track towards the Philippines.

Residents and visitors along Extreme Northern Luzon and Taiwan should closely monitor the development of TY GONI (INENG).
