TEMBIN (IGME) rapidly intensified into a Typhoon after remaining almost stationary over the Philippine Sea, east of moving very slowly northward. Outer rainbands continues to spread across the east coast of Cagayan and Isabela.

Meanwhile, since the Southwest Monsoon (Habagat) remains weak, the pull of Typhoon TEMBIN on this seasonal wind system is not much. However, isolated to scattered rains and thunderstorms can still be expected across much of Luzon including Metro Manila and Baguio City.

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

TEMBIN (IGME) is expected to continue moving very slowly northward to NNE during the next 12 to 36 hours...and will turn sharply NW to Westward during the next 48 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 through Thursday...with a dangerous path towards Eastern Taiwan.

Maximum Sustained Winds (1-min. avg) have rapidly increased to near 120 km/hr (65 knots) with higher gusts. Continued increase in strength will be expected during the next few days...and TEMBIN will become a Category 2 Typhoon on Tuesday.

Tropical Storm Force Winds (62-100 km/hr) extend outward up to 85 kilometers (45 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:

TUESDAY MORNING: Strengthens into a Category 2 Typhoon as it starts to turn NW-ward while off the North Philippine Sea...316 km ESE of Basco, Batanes [6AM AUG 21: 20.1N 125.0E @ 160kph].
WEDNESDAY MORNING: Still gaining strength as it nears Category 3 strength turns more WNW closer to Eastern Taiwan...about 320 km SE of Hualien City, Taiwan [6AM AUG 22: 22.4N 124.2E @ 175kph].
THURSDAY MORNING: Bears down the coast of Eastern Taiwan...turns more Westward...about 78 km SE of Hualien City, Taiwan [6AM AUG 23: 23.4N 122.0E @ 175kph].

*Please be reminded that the Forecast Outlook changes every 6 hours, and the Day 3 Forecast Track have an average error of 250 km...while the wind speed forecast error, averages 35 kph per day. Therefore, a turn to the left or right of its future track and changes in its wind speed must be anticipated from time to time.
