Super Typhoon Inday’s outer bands, southwest monsoon may bring scattered rain

MANILA, Philippines – The outer bands of Super Typhoon Inday (Bavi) and the southwest monsoon or habagat could bring scattered rain and thunderstorms to parts of the country, the weather bureau said on Wednesday afternoon, July 8.

Inday was last spotted 1,170 kilometers east of Northern Luzon, moving west at 20 kilometers per hour (km/h).

The super typhoon currently has maximum sustained winds of 195 km/h and gustiness of up to 240 km/h, but it could weaken into a typhoon by Thursday evening, July 9, or early Friday morning, July 10.

In its 5 pm bulletin on Wednesday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Inday remains likely to stay over the Philippine Sea.

Inday may be nearest to extreme Northern Luzon by Friday evening or Saturday morning, July 11, before heading toward Japan’s southern islands and the sea north of Taiwan. As a result, from Friday afternoon to Saturday afternoon, Batanes is likely to have moderate to heavy rain (50-100 millimeters).

While Inday’s center is far from land, its outer rainbands may affect Eastern Visayas and Bicol on Wednesday evening. Flash floods and landslides are possible.

Also on Wednesday evening, the southwest monsoon could bring scattered rain and thunderstorms to Palawan, Antique, Iloilo, Guimaras, Negros Occidental, Negros Oriental, the Zamboanga Peninsula, the Bangsamoro Autonomous Region in Muslim Mindanao, Lanao del Norte, Sultan Kudarat, Sarangani, and South Cotabato, as well as isolated rain showers or thunderstorms to the rest of the Visayas and the rest of Mindanao.

The separate three-day rainfall outlook for the southwest monsoon shows the following areas may see the most rain, as Inday will be enhancing the habagat:

Wednesday afternoon, July 8, to Thursday afternoon, July 9

• Moderate to heavy rain (50-100 mm): Antique, Negros Occidental, Sultan Kudarat, Sarangani
