Super Typhoon Songda (Chedeng) Update #14

Songda (Chedeng) is now a Category 5 Super Typhoon with maximum sustained winds of around 260kph and gusts reaching up to 315kph. It was last located approximately 280km ENE of Casiguran, Aurora or about 310km ESE of Tuguegarao, Cagayan. Songda is moving NW-ward at 15kph. Overall structure of Songda is very amazing and no sign of eyewall replacement just yet. We are expecting one more burst of intensification this morning, probably peaking at around 280kph sustained.

Rain bands and tropical storm winds (less than 120kph) can be felt as far west as Tuguegarao and Aparri starting tonight into early tomorrow. Rough seas should also be expected with wave heights as high as 2m.

As of 11pm tonight, Signal #1 is still in effect for Batanes Grp of Islands, Cagayan, Calayan Grp, Babuyan Grp, Isabela, Quirino, Aurora, Quezon, Polilio Is., Camarines Norte, Camarines Sur, Catanduanes, and Albay.

Forecast track has not changed since our last update. NO LANDFALL based on current trends although Cagayan, Isabela, Aurora, and even Quezon should still feel the effects of Songda tomorrow. After passing east of Cagayan tomorrow morning, STY Songda should start to slowly turn to the northeast. It will also start weakening as the sea temperatures begin to get colder. It'll approach Okinawa by Sunday as a strong Category 3 typhoon.
