In the weather forecast bulletin for the morning of December 21, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said that the northeast monsoon is affecting Batanes province, where showers are likely to appear.
We expect that in the next few days, or at least tomorrow, this northeast monsoon will continue to strengthen, said Mr. Obet Badrina, a weather expert of PAGASA.
Mr Badrina also noted that there is no warning of strong winds at sea, but the possibility of a warning on December 21 is possible, as the winds of the northeast monsoon are forecast to increase.
In addition to the northeast monsoon, wind shear and easterly winds are also continuing to affect the weather in most of the Philippines.
The wind shear, which lines the northeast and east winds, is expected to bring moderate to heavy rains to the provinces of Cagayan and Isabela.

In Palawan, the weather is forecast to be cloudy, with scattered showers and thunderstorms due to the influence of the winter wind.
