The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said the trough of Super Typhoon "Leon" may bring cloudy skies with scattered rains over Metro Manila on Thursday.

Pagasa weather specialist Jeremy Aguilar told the Daily Manila Shimbun that "improving weather condition" is expected over Metro Manila and the remaining parts of Luzon, before All Saints Day on Friday.

"Leon" intensified into a super typhoon on Wednesday morning.

In Pagasa's 5pm advisory, ''Leon'' was located at 215 km east southeast of Basco, Batanes moving northwest at 20kph. It has winds of 185 km/h with gusts of up to 230 km/h.

The super typhoon is forecast to be close to Batanes on Wednesday late evening until Thursday morning.

As the typhoon is around the "area of uncertainty" Pagasa is not ruling out the possibility of a landfall over Batanes on Wednesday late evening until Thursday morning.

Tropical Cyclone Wind Signal 4 was hoisted over Batanes.

Areas under Tropical Cyclone Wind Signal 3 are the eastern portion of Babuyan Island and the northeastern portion of mainland Cagayan (Santa Ana).
