Tropical Depression 09W (Ferdie) Update #2

Tropical Depression 09W (Bagyong Ferdie) is now moving across Luzon Strait. The system was last located approximately 60km north of Aparri, Cagayan. Maximum sustained winds remain at 45kph with gusts of up to 65kph. 09W/Ferdie is currently moving westward at 20kph.

As of 5am today, PAGASA has issued Public Storm Warning Signal #1 for Isabela, Cagayan , Calayan Grp of Is , Babuyan Gr of Is, Batanes Gr of Is, Kalinga, Apayao, Abra, Ilocos Norte, Ilocos Sur, and Mt. Province. These areas will continue to get scattered showers and breezy conditions throughout today. Coastal areas, particularly along Ilocos Norte and the Western coast of Luzon, will also experience rough waves in the next 2 days.

Latest satellite image continues to show the depression struggling to consolidate. Multiple vortices appear to be rotating around a common center situated just north of Aparri. Convective activity remains weak and is displaced to the southwest. North to northeasterly wind shear remains moderate in the region although it is expected to weaken tomorrow. Much of the convective activity is located across the West Philippine Sea pulling the SW Monsoon towards that area. However, scattered rain showers will still affect much of Luzon, Palawan, and Visayas throughout today. Some areas could receive another 40 to 80mm today.

TD 09W (Bagyong Ferdie) will continue moving towards the West Philippine Sea today and could exit the Philippine Area of Responsibility tomorrow morning. It is forecast to strengthen tomorrow as the shear relaxes. It will pass south of Hong Kong and is forecast to head into the direction of either Hainan or Guangdong Province.

We'll have another update later this afternoon.
Issued (23 UTC) 7am PhT 072112
