MANILA, Philippines -- The state weather bureau continues to monitor a shallow low pressure area east of Luzon as the temperatures begin to drop due to the northeast monsoon.
"We are monitoring the shallow low pressure areas. It could develop into a [weather disturbance] but at this point there's no indication that it would happen," Dr. Prisco Nilo, chief of the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) told the Inquirer by phone, on Sunday.
The shallow low pressure area was spotted at an estimated 610 kilometers, east of Luzon and would bring scattered rainshowers and thunderstorms, PAGASA said in its 24-hour weather forecast issued at 5 p.m. on Sunday.
For most of the week, Metro Manila, and the cities of Tuguegarao, Laoag, Baguio, Olongapo, Angeles, and Tagaytay would be partly cloudy to at times cloudy with isolated rainshowers, PAGASA said.
The cities of Legaspi, Puerto Princesa, Iloilo/Bacolod, Cebu, Tacloban, Cagayan de Oro, Davao, and Zamboanga will be partly cloudy to at times cloudy with isolated rainshowers and thunderstorms.
Meanwhile, the mornings start to become chilly because of the north east monsoon.
On Sunday, the PAGASA Science Garden in Quezon City recorded the lowest temperature in Metro Manila at 19.8 degrees Celsius at 4:50 a.m.
It was slightly colder in Tagaytay and Cabanatuan where the minimum temperature was recorded at 19.5 degrees Celsius.
On Monday, the temperature is expected to dip to 15 degrees Celsius in Baguio City and 18 degrees Celsius in Tagaytay City.
"It's quite cold now and the temperature will be lower in December. The cold temperature came a bit early today because the typhoons induced the northeast monsoon," Nilo said.
The northeast monsoon is the cold air from the northern hemisphere that blows into the country from the end of October to January.
Typhoon "Santi", the third tropical cyclone to lash at the country in just a month, was forecasted to be at 800 kilometers west southwest of Metro Manila by Sunday night.
