As of 6 am today, the center of Typhoon Bopha was located over the West Philippine Sea...about 286 km northwest of San Vicente, Palawan or 291 km west-northwest of El Nido, Palawan...currently moving northwest with a forward speed of 9 km/hr in the general direction of the West Philippine Sea.

Maximum Sustained Winds (1-min. avg) remain at 120 km/hr near the center with higher gusts. Typhoon Force Winds (118 km/hr or more) extend outward up to 35 kilometers from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 175 kilometers. Bopha is an average-sized tropical cyclone with a diameter of 555 kilometers across. The 24-hour rainfall accumulation near the center of Typhoon Bopha is estimated to be exteme (500 mm).


Typhoon Bopha is expected to turn west-northwestward for the next 24 hours with a rapid decrease in its forward speed throughout the forecast period. On the forecast track, the core of Bopha is expected to continue moving farther away from Northern Palawan...and will be over the West Philippine Sea until Sunday as it is predicted to slow down or remain almost stationary.

Bopha will slightly re-intensify during the next one to two days, as the system encounters some warm temperatures off the West Philippine Sea. However, this typhoon may dissipate after 2 days due to the surge of cool and dry air, brought about by the northeast monsoon.

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

FRIDAY MORNING: Moving northwest farther away from Northern Palawan towards the West Philippine 476 km west-southwest of Lubang Island [6AM DEC 07: 12.9N 115.9E @ 130kph].
SATURDAY MORNING: Maintain its strength as it slows down further while over the West Philippine Sea...about 563 km west-southwest of Lubang Island [6AM DEC 08: 13.5N 115.0E @ 130kph].
