Philippine officials have already issued an alert and began advising people to leave the east coast, as the powerful typhoon approaches from the east. Super Typhoon Haiyan has already hit the outer islands, with maximum winds of 240 km/h and gusts of up to 295 km/h. The typhoon has since then further intensified, with maximum wind speeds now over 260 km/h and gusts over 300 km/h, which is equal to a category 5 hurricane on the Saffir–Simpson scale. Haiyan is expected to reach central Philippines as a super typhoon by Friday noon local time, with winds around 235-250 km/h, which is equal to a strong category 4 hurricane on the Saffir–Simpson scale.
Among the areas expected to be hit by Haiyan, are the provinces of Bohol and Cebu which were struck by a magnitude-7.2 earthquake on October 15. The earthquake killed over 220 people and left more than 380,000 people homeless.
