Severe Tropical Storm Inday (international name: Muifa) has intensified into a typhoon and its trough may bring heavy rain showers during thunderstorms over the eastern section of Southern Luzon and the western portion of Central Luzon as it moves northwestward over the Philippine Sea, PAGASA said Saturday.
In its 11 a.m. bulletin, PAGASA said Inday remained less likely to directly bring heavy rains in the country throughout the forecast period.
"The latest forecast scenario for INDAY shows that while the hoisting of Tropical Cyclone Wind Signals remains less likely at this time, further westward shift in the track forecast and/or expansion in the extent of tropical cyclone winds may result in the hoisting of wind signals over portions of Extreme Northern Luzon," PAGASA said.
Inday may also enhance the Southwest Monsoon (Habagat), which may bring rains over the western sections of Southern Luzon and Visayas, it added.
Moderate to rough seas may thus be expected over the seaboards of Batanes (2.0 to 4.0 m) and Babuyan Islands (1.5 to 3.0 m) in the next 24 hours due to Inday.
The conditions may be risky for those using small seacraft. Mariners are advised to take precautionary measures when venturing out to sea and, if possible, avoid navigating in the said conditions during the said period.
Based on the track and intensity outlook, Inday is forecast to move generally northwestward over the Philippine Sea on Saturday through Monday as it tracks towards the sea east of Taiwan.
Inday may exit the Philippine Area of Responsibility (PAR) and pass close to the Miyako or Yaeyama Islands in Japan by late Tuesday or early Wednesday. —Jamil Santos/KG, GMA News
