Metro Manila (CNN Philippines, August 11) — Manila Bay overflowed due to heavy downpour Saturday morning, leaving the stretch of Roxas Boulevard flooded and full of garbage.

Videos obtained by CNN Philippines showed loads of trash, mostly plastic materials from the sea on both lanes of Roxas Boulevard right in front of the bay.

Both lanes were not passable to light vehicles as of 9:20 a.m., the Manila Police District said.

Volunteers later picked up garbage by the sea wall.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said heavy rains will continue to pour over parts of the country despite Tropical Storm Karding's exiting before noon on Saturday.

Karding and a tropical depression outside the country both strengthen the southwest monsoon, weather officials said.

Some cities and municipalities in Luzon have suspended classes Saturday due to the monsoon rains.
