MANILA, Philippines — The tropical cyclone outside the Philippine area of responsibility (PAR) has weakened into a low-pressure area (LPA), according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
The weather disturbance was downgraded into an LPA at 8 p.m. on Saturday, PAGASA weather specialist Grace Castañeda said.
“It (LPA) will have no direct effect in any parts of the country. The easterlies or warm wind from the Pacific Ocean continue to affect the eastern portion of southern Visayas and Mindanao,” Castañeda said.
Castañeda added that many areas in the country will experience humid weather.
“We will experience isolated rains especially in the western part of Mindanao due to the easterlies and localized thunderstorms,” she said.
“Extreme Northern Luzon and other portions of Northern Luzon will have high chances of rain because of the LPA once it reaches Taiwan. The frontal system will also bring rains in these areas,” she added.
Based on the outlook of the weather state bureau from June 5 to 7, the southwest monsoon is expected to bring mostly cloudy skies with scattered rains and isolated thunderstorms over the western section of Luzon.
PAGASA has said that one to two tropical cyclones may develop within PAR in June.

At least 44 areas in the country are forecast to experience “danger” heat index of 42 to 48 degrees Celsius today even as PAGASA has already declared the onset of rainy season.
