MANILA, Philippines – Ambo (Vongfong) weakened from a tropical depression into a low pressure area (LPA) on Sunday afternoon, May 17, while moving over the Bashi Channel.

In a bulletin issued 5 pm on Sunday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said the LPA which used to be Ambo is now 125 kilometers northwest of Basco, Batanes.

With the development, Signal No. 1 has been lifted in Batanes. (READ: Why is it now called tropical cyclone ‘wind’ – and not ‘warning’ – signals?)

But PAGASA said light to moderate rain will still persist in Batanes until Sunday night. The rain may be heavy at times.

Seas off Batanes and Babuyan Islands will also be moderate to rough. PAGASA advised fishermen and those with small vessels not to set sail. (READ: FAST FACTS: Tropical cyclones, rainfall advisories)

Ambo was a typhoon when it lashed parts of Eastern Visayas, Bicol, and Calabarzon, then gradually weakened as it crossed other areas in Luzon. It made landfall 6 times as a typhoon and once as a severe tropical storm, in these areas:

  • May – 1 or 2
  • June – 1 or 2
