Weather bureau PAGASA on Friday said Inday has intensified into a severe tropical storm while another low pressure area has been spotted outside the Philippine area of responsibility.

As of 10 a.m., the center of Severe Tropical Storm Inday was estimated based on all available data at 925 km east northeast of Basco, Batanes. Inday, which is packing 90 kph winds and 115 kph gusts, is moving northwest at 15 kph and is expected to exit PAR Friday night or Saturday morning.

Weather forecasters said an LPA outside PAR was estimated based on all available data at 475 km west of Laoag City, Ilocos Norte as of 10 a.m.

The southwest monsoon (habagat) enhanced by Inday and the low pressure area will bring intermittent moderate to heavy monsoon rains over Ilocos Region, Cordillera Administrative Region, Zambales, Bataan, Pampanga, Bulacan, Tarlac and Nueva Ecija.

It will also bring scattered light to moderate with occasional heavy rains over Metro Manila and the rest of Luzon until tomorrow (21 July).

"Residents of these areas, especially those living in low-lying and mountainous areas, are advised to take appropriate actions against possible flooding and landslide, coordinate with local disaster risk reduction and management offices, and continue monitoring for updates," PAGASA said.

Sea travel remains risky over the western seaboard of Central Luzon due to habagat.

Inday, the third tropical cyclone to hit the country this month, has triggered floods and forced the cancellation of classes in some areas.
