The typhoon with the international name "Mindulle" further intensified while moving slowly over the Philippine Sea on Sunday, Sept. 26.
In the 11 a.m. tropical cyclone advisory, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said Mindulle was packing maximum sustained winds of 185 kilometers per hour (kph) near the center and gustiness of up to 230 kph while moving west-northwestward slowly.
"Highly favorable conditions will allow Mindulle to continue rapidly intensifying within the next 36 hours over the warm waters of the Philippine Sea. It may reach a peak intensity of around 205 to 215 kph by Monday (Sept. 27)," PAGASA said.
As of 10 a.m., the center of the eye of the typhoon was estimated at 1,590 kilometers east of northern Luzon.
Based on the latest forecast, PAGASA said Mindulle is likely to enter the Philippine area of responsibility (PAR) briefly between Tuesday and Wednesday, Sept. 28 and Sept. 29.
Mindulle will be given a local name "Lannie" once inside the PAR.
However, PAGASA said the weather disturbance is less likely to directly affect the country's weather condition throughout the forecast period but may cause moderate to rough seas over the northern and eastern seaboards of Luzon beginning Monday.
"Sea travel will be risky for those using small sea crafts. Mariners are advised to take precautionary measures when venturing out to sea and, if possible, avoid navigating in these conditions," it advised.
PAGASA on Sunday said the intertropical convergence zone (ITCZ) remains the dominant weather system in the country.
Scattered rain showers and thunderstorms may prevail over Visayas, Zamboanga Peninsula, Northern Mindanao, Caraga, and Palawan in the next 24 hours.
Meanwhile, Metro Manila and the rest of the country will have partly cloudy to cloudy conditions with isolated rain showers caused by the ITCZ and localized thunderstorms.
PAGASA continued to advise the public to take precautions against possible flash floods or landslides especially during the occurrence of severe thunderstorms that are often associated with short-lived heavy rains.
