It will then move northward or north northeastward by mid Wednesday or Thursday towards the sea east of Taiwan.

This typhoon will likely remain as a typhoon throughout the forecast period, although it is expected to gradually weaken until Tuesday. Afterwards, increasingly unfavorable environment while moving northward or north northeastward on Wednesday or Thursday will result in a faster weakening rate.

It may be downgraded to severe tropical storm category on late Thursday or early Friday.

PAGASA said that Typhoon 'Betty' will also enhance the Southwest Monsoon this week:

Tomorrow: Monsoon rains are possible over the western portions of MIMAROPA and Western Visayas

Tuesday: Monsoon rains are likely over the western portions of MIMAROPA and Western Visayas

Wednesday: Monsoon rains are likely over the western portions of MIMAROPA and Western Visayas.


'Bagyong Betty' is the second tropical cyclone for 2023, known as the strongest Northern Hemisphere cyclone to form in the month of May. It originated from an area of low-pressure south-southwest of Chuuk Lagoon in the central Pacific that developed into a tropical depression on May 19.

On average, there are 20 tropical cyclones that could form or enter the PAR each year. Only half of those are projected to make landfall.

PAGASA is expected to soon declare the start of the country’s rainy season, which usually begins in the second half of May or first half of June.
