MANILA, Philippines—Expect a rainy weekend in Metro Manila, Southern Luzon and parts of the Visayas and Mindanao, the Philippine Atmospheric, Geophysical and Astronomical Services Administration said Friday.

Nonoy About of the PAGASA forecasting center said the rains are caused by the tailend of a cold front affecting the Visayas and parts of Luzon.

“We expect rains for the next three days. But next week, we expect conditions to improve,” he told the Inquirer.

About said weathermen spotted a shallow low-pressure area 100 kilometers east of Surigao City and it moving westward across the Visayas region. “This means rains in the area, mostly the eastern parts.”

A low-pressure area is considered by weather forecasters as a mild form of tropical depressions. Cold fronts are formed in the boundaries of masses of cold and warm air. This meeting leads to the formation of clouds and rain.

About said they do not expect the low-pressure area to intensify into a tropical cyclone.
