Weather tracker: Typhoon Gaemi wreaks havoc in Philippines and Taiwan

Half a million people evacuated, 21 deaths confirmed so far and capsized tanker in Manila causes huge oil spill

Typhoon Gaemi has been wreaking havoc, with the Philippines government forced to declare a state of calamity last week in its capital Manila, and flooding and at least three deaths in Taiwan. . Manila received more than 300mm of rainfall, with resulting floods reaching as high as one-storey buildings in places. More than half a million people have been evacuated or displaced, with 21 deaths confirmed so far.

Gaemi initially developed on Sunday as a tropical storm to the east of the Philippines and then tracked north-west, strengthening until it achieved typhoon status on Monday as it drew level with the northernmost tip of the Philippines. Despite not making landfall in the Philippines, the typhoon interacted with existing monsoon weather systems, worsening the already heavy rains across the island of Luzon and causing several landslides.
