MANILA, Philippines – The trough or extension of a low pressure area (LPA) outside the Philippine Area of Responsibility (PAR) will continue to affect parts of the country.

In a Facebook Live video past 5 pm on Saturday, July 13, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said the LPA is already 1,450 kilometers east of the Visayas.

Even though the LPA remains outside PAR, its trough is bringing rain to Palawan, the Visayas, and Mindanao.

Residents of those areas should expect scattered rainshowers and thunderstorms. Flash floods and landslides are possible.

PAGASA Weather Specialist Aldczar Aurelio said on Saturday that the LPA could enter PAR by Monday, July 15. It was initially seen to enter on Sunday, July 14.

The LPA might also develop into a tropical depression on Tuesday, July 16, or on Wednesday, July 17.

If it becomes a tropical depression inside PAR, it would be the Philippines’ 6th tropical cyclone for 2019 and would be given the local name Falcon. (READ: LIST: PAGASA’s names for tropical cyclones in 2019)

The potential tropical depression is also expected to enhance the southwest monsoon or hanging habagat.

At the moment, the southwest monsoon is still temporarily weak – a period called a monsoon break. The monsoon break has been ongoing for more than a week. (READ: FAST FACTS: Tropical cyclones, rainfall advisories)

The rest of Luzon, not affected by the trough of the LPA, will only have isolated rainshowers or localized thunderstorms.

The Philippines gets an average of 20 tropical cyclones annually, but since 2019 is an El Niño year, only 14 to 18 tropical cyclones are expected.

Below is the estimated number of tropical cyclones from July to December:

  • July – 2 or 3
  • August – 2 to 4
  • September – 2 to 4
  • October – 2 or 3
  • November – 1 or 2
  • December – 0 or 1

PAGASA declared the start of the rainy season last June 14. – Rappler.com
