Typhoon Quiel changed course and picked up strength. State weather forecasters now expect the cyclone to bring its winds of 160-195 kilometers per hour to the Isabela-Aurora area, sparing Cagayan province from the brunt of its impact upon landfall.

Storm Signal No. 3 now covers northern Aurora and the provinces of Isabela, Mountain Province, Ifugao, Nueva Vizcaya, Quirino, Benguet, Ilocos Sur, La Union, and Pangasinan, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) in its 5 a.m. severe weather bulletin Saturday.

PAGASA said no longer under Signal No. 3 but now under Signal No. 2 are Cagayan, Apayao, Abra and Kalinga. Also under Signal No. 2 are:

- Ilocos Norte
- the rest of Aurora
- Nueva Ecija
- Tarlac
- Pampanga
- Zambales
- Bulacan
- northern Quezon
- Polillo Island

Signal No. 1 was hoisted over Metro Manila and these areas:

- the rest of Quezon
- Camarines Norte
- Rizal
- Bataan
- Cavite
- Laguna
- Batangas
- Lubang Island
- Babuyan Islands
- Calayan Group of Islands

Quiel is still forecast to dump up to about one inch of rain per hour within its 500-kilometer span. Estimated rainfall over the Magat dam catchment area is 200 – 400 millimeters (mm) or 8 to 16 inches.

Quiel-induced monsoon clouds over the catchment area of Angat dam are forecast to bring rainfall of 80 – 100 mm or 3 to 4 inches.

Seven spill gates of the Magat dam in Isabela province were raised open to 12 meters to let out water and make way for rain from Typhoon Quiel which is expected to make landfall Saturday morning.
