Powerful Typhoon TEMBIN (IGME) has moved NNE slowly during the past 12 hours...now with powerful winds of 215 km/hr. Threat to the Philippine Islands diminishing as it aims for Taiwan.

Since the Southwest Monsoon (Habagat) remains weak, the pull of Typhoon TEMBIN on this seasonal wind system is still not much. However, isolated to scattered rains and thunderstorms will continue is some parts of Luzon including Metro Manila and Baguio City.

Meanwhile, the other cyclone - Tropical Storm BOLAVEN (16W) continues to intensify while over the Western Pacific Ocean, NW of Guam. Check out the latest details on this system at the TROPICAL CYCLONE WATCH section of this page.

Residents and visitors along Northern Luzon and Taiwan should closely monitor the progress of TEMBIN (IGME).

TEMBIN (IGME) is expected to continue moving slowly northward during the next 12 to 24 hours...and will turn sharply WNW to Westward during the next 36 to 72 hours. On the forecast track, the core of TEMBIN will not directly affect any part of the Philippines as it will remain over the open sea. This typhoon will be approaching the East Coast of Taiwan early Thursday morning...and will make landfall south of Hualien City on Thursday afternoon at approx. 2PM and traverse Taiwan. By early Friday morning, TEMBIN will emerge over the Taiwan Strait in the direction of Southern China.

Maximum Sustained Winds (1-min. avg) have rapidly increased to near 215 km/hr (115 knots) with higher gusts. Still some increase in strength will be expected during the next few days, prior to making landfall...and TEMBIN could become a Super Typhoon by Wednesday afternoon.

Typhoon Force Winds (118 km/hr or more) extend outward up to 55 kilometers (30 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 185 kilometers (100 nautical miles) from the center. TEMBIN is an average-sized tropical cyclone with a diameter of 665 kilometers (360 nautical miles) across.

The following is the summary of the 3-day forecast outlook on this system:

WEDNESDAY MORNING: Nearing Super Typhoon status as it turns WNW to Westward...about 302 km NE of Basco, Batanes [6AM AUG 22: 21.9N 124.5E @ 230kph].
THURSDAY MORNING: Starts to lose strength as it bears down the coast of Eastern Taiwan...about 147 km SE of Hualien City, Taiwan [6AM AUG 23: 22.9N 122.4E @ 215kph].
FRIDAY MORNING: Emerges over the Taiwan Strait after crossing Taiwan...weakens to Category 3...approaching Eastern Guangdong in Southern China...about 99 km NW of Kaohsiung City, Taiwan [6AM AUG 24: 23.3N 119.7E @ 185kph].
