Typhoon Inday (Muifa) leaves the Philippines area of responsibility early Tuesday, September 13. Meanwhile, PAGASA is monitoring a tropical depression outside the PAR.
MANILA, Philippines – Typhoon Inday (Muifa) left the Philippines Area of Responsibility (PAR) at 12:40 a.m. Tuesday, September 13, more than five days after entering as a tropical storm.
Inday was last spotted 560 kilometers northeast of Itbayat, Batanes, already high above the East China Sea, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Tuesday in his 5 a.m. newscast.
The typhoon is slowly moving northeast, heading towards China’s east coast, where it could eventually make landfall in Shanghai or Zhejiang.
Tuesday morning Inday had maximum sustained winds of 140 kilometers per hour and gusts of up to 170 km/h.
PAGASA said squalls could persist in far northern Luzon on Tuesday and Wednesday, September 14, “due to the channeling of typhoon circulation through the Luzon Strait”.
Inside the PAR, Inday’s maximum sustained winds had peaked at 165 km/h. But the typhoon stayed clear of the Philippine landmass and tropical cyclone wind signals were not given.
The Inday trough or extension brought only scattered rain showers and thunderstorms to parts of Luzon and the Visayas. The typhoon also briefly reinforced the southwest monsoon or suspended cabin.
Despite the release of Inday from the PAR, a gale warning was still issued for the coasts of Batanes and Babuyan islands at 5 a.m. Tuesday.
PAGASA said the sea remains rough to very rough, with waves 2.8 to 4.5 meters high.
The weather bureau advised fishing boats and other small vessels not to sail, and larger vessels to watch out for large waves.
Inday was the Philippines’ ninth tropical cyclone for 2022 and the first for September.
After Inday, PAGASA monitors a tropical depression outside PAR.
The tropical depression was located 1,720 kilometers east of far northern Luzon before dawn on Tuesday, moving slowly eastward over the Philippine Sea.
It has maximum sustained winds of 45 km/h and gusts of up to 55 km/h.
PAGASA said the tropical depression is expected to drift east northeast or become nearly stationary for the next 36 hours before “turning sharply” northwest or west northwest on Thursday, September 15, as that it is accelerating.
At this rate, he could enter PAR on Thursday afternoon or evening and be given the local name of Josie.
By the time it enters the PAR, it may already be a typhoon. PAGASA said a “modest intensification is likely” on Tuesday and Wednesday, while “improving environmental conditions will allow the tropical cyclone to intensify at a relatively faster rate” by Thursday.
Potential Josie shouldn’t make landfall in the Philippines. It will not directly affect the weather in the country.
But PAGASA said it could strengthen the southwest monsoon, which could bring monsoon rains to western parts of southern Luzon and the Visayas from Wednesday or Thursday.
PAGASA expects 7 to 11 tropical cyclones to enter or develop inside the PAR from September 2022 to February 2023. By month, here are the weather bureau estimates:
- September 2022 – 2 or 3
- October 2022 – 2 to 4
- November 2022 – 2 or 3
- December 2022 – 1 or 2
- January 2023 – 0 or 1
- February 2023 – 0 or 1
