NORTH Luzon will experience gusty winds and rains until Thursday as the low pressure area (LPA) off east of Infanta, Quezon has developed into a tropical depression.
The state weather bureau has named Tuesday morning the ninth tropical cyclone to enter the country as Isang.
Weather Forecaster Chris Perez said that at least 13 areas in Northern Luzon have been placed under public storm warning signal no. 1 (45-60 kph winds): Abra, Ilocos Norte, Ilocos Sur, Ifugao, Cagayan including Calayan and Babuyan Group of Islands, Isabela, Quirino, Aurora, Mt. Province, Kalinga and Apayao.
Residents living in low lying and mountainous areas under public storm warning signal 1 are alerted against possible flashfloods and landslides.
Perez said as of 4 a.m. Tuesday, tropical depression Isang was estimated at 300 km East of Infanta, Quezon packed with maximum winds of 45 kph near the center.
He added that Isang is forecast to move west northwest at 19 kph. With this speed, it is expected to be out of Philippine Area of Responsibility (PAR) by Thursday and will move towards Southern China.
Perez also said that Isang has small chance to intensify as it is expected to make a landfall in Casiguran, Aurora by 6 p.m. Wednesday.
In the next six to 12 hours, the western section of Luzon including Metro Manila and the Visayas will experience light to moderate rains as the tropical depression Isang will enhance the southwest monsoon.
In its advisory, Pagasa said that Ilocos Region, Cagayan Valley, Babuyan and Calayan Islands, CAR and the Province of Aurora will have rains and gusty winds with moderate to rough seas.
Bicol region will have cloudy skies with moderate to heavy rains and thunderstorms which may trigger flash floods and landslides.
It added that Metro Manila, Central Luzon, Calabarzon, Mimaropa and Visayas will have cloudy skies with light to moderate rain showers and thunderstorms. Mindanao will be partly cloudy to cloudy with isolated rain showers or thunderstorms.
Pagasa also said that moderate to strong winds blowing from the southwest to southeast will prevail over the rest of Luzon and the coastal waters along these areas will be moderate to rough.
Elsewhere, winds will be light to moderate coming from the west to southwest with slight to moderate seas. PNA
