The storm known as Haiyan is estimated to be one of the most ferocious ever recorded, with winds gusting to over 220mph.
The Philippines is currently bracing itself to cope with one of the most powerful storms the world has ever seen. The central area of the country, around Cebu province, is expected to be hardest hit, with millions fleeing the area looking for shelter.
To get a sense of just how big and powerful this storm is, these two pictures should help.
The first is this satellite image, showing the intensity of the storm, and its powerful rotating centre.
But the second one, from European meteorological group EUMETSAT, shows the sheer size of the storm as it bears down on the Philippines and south-east Asia.
We hope everybody gets through it okay.
