MANILA, Philippines (UPDATE) – Weather bureau PAGASA has lifted the “yellow alert” over Metro Manila.

PAGASA earlier hoisted a “yellow alert” warning, saying that moderate to heavy (5 to 12 millimeter per hour) of rains are expected over the southern part of Metro Manila at 12 noon Friday.

“Pasay, Taguig, Parañaque, Las Piñas and Muntinlupa, and may also effect Manila, Pasig, Mandaluyong and San Juan. Rain may prevail for 3 hours,” PAGASA said in its official Twitter account.

The warning was lifted at 4:48 p.m.

PAGASA issues the following alerts when there are strong rains but no storm is present:

  • Yellow – 7.5 to 15 mm rainfall expected within one hour
  • Green – 15 mm to 30 mm rainfall expected within one hour
  • Red – 30 mm and above rainfall expected within one hour

PAGASA is monitoring an active low pressure area (ALPA) that was spotted 330 kilometers east of Tuguegarao as of 8 a.m.

The ALPA, combining with the effects of the southwest monsoon (hanging habagat), will “bring scattered rainshowers and thunderstorms to widespread rains and thunderstorms in Luzon and Visayas which may trigger flashfloods and landslides.”

Should the active LPA becomes a cyclone, it will be named “Ferdie.” It will be considered a tropical depression once it gains wind strength between 55 and 64 kilometers per hour.
