MANILA, Philippines – An active low pressure area (ALPA) spotted east of Mindanao has a slim chance of making landfall, a state weather forecaster said on Tuesday.

Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) forecaster Nikos Peñaranda said the ALPA, located 760 east of Hinatuan, Surigao del Sur as of 2 a.m., is heading towards the area between Taiwan and southern Japan.

However, the ALPA may still enhance the southwest monsoon (habagat), bringing rains over Luzon and parts of Visayas.

If the ALPA develops into a tropical cyclone while still inside the Philippine Area of Responsibility (PAR), it will be named "Karen".

The ALPA was still too far to affect any part of the country. The thunderstorms experienced in parts of Luzon, Visayas and Mindanao were caused by the Intertropical Convergence Zone (ITCZ).

The ALPA is also embedded along the ITCZ, which is formed when trade winds from the southern and northern hemispheres meet, creating thunderstorm-producing cloud bands.

The ITCZ is also the area where most weather disturbances such as LPA are formed.

Peñaranda said the country is expected to experience wet weather in the coming days as another cloud mass is forming in the West Philippine Sea.

He said the clouds may develop into a LPA, which may move northward and bring rains over the country.
