Taiwan is battening down for high winds and heavy rain as Typhoon Chanthu roars towards the island.
The weather bureau issued a typhoon warning for the southern half of Taiwan late on Friday after Chanthu passed through Philippine waters with sustained winds of 215km/h and gusts up to 265km/h.
Forecasters expect Chanthu to pass Taiwan's east coast on Sunday, but the outer edge of the storm should dump rain on the island.
On Friday, Philippine authorities issued storm warnings for Cagayan and Ilocos Norte provinces on its northern island of Luzon and for sparsely inhabited islands of Luzon's northern coast.
There were no immediate reports of flooding or damage.
Chanthu's wind speeds put it on the verge of becoming a "super typhoon", which has winds of at least 220km/h.
The bureau said high waves were expected along Taiwan's southern coast and in the Bashi Channel between its southern tip and the northernmost island in the Philippines.
A smaller typhoon slammed into the eastern Philippines on Tuesday, causing power outages in several provinces before weakening into a severe tropical storm as it moved west-northwest over the Sibuyan Sea.
