MANILA -- The seventh storm to enter the Philippines this year is heading towards Japan as the state weather bureau Tuesday warned of more rains especially in Luzon due to the enhanced southwest monsoon.

In its final storm update, the Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa) said Typhoon Glenda (international name: Kompasu) is spotted at 830 kilometers northeast of Basco, Batanes while moving northwest at 19 kilometers per hour.

Glenda has maintained its strength of 120 kph near the center and gustiness of up to 150 kph as of 10:30 a.m. Tuesday.

By Tuesday evening, it is expected to be at 850 km northeast of Basco, Batanes or 40 km north of Okinawa, Japan.

Pagasa said it is expecting between 13 to 15 storms to visit the country this year, lower than the average of 19.

In an earlier bulletin, Pagasa said Northern and Central Luzon will experience monsoon rains while the rest of country will have mostly cloudy skies with scattered rainshowers or thunderstorms.

Moderate to strong winds blowing from the southwest will prevail over Luzon and its coastal waters will be moderate to rough.

Elsewhere, winds will be light to moderate blowing from the Southwest with slight to moderate seas, the weather bureau added. (Virgil Lopez/Sunnex)
