A second typhoon in a week is barreling into the Philippines, killing two people, with more than 900,000 residents warned to flee the looming destructive winds and life-threatening storm surges.

The U.S. Embassy in the Philippines has issued a weather alert warning American citizens to heed local guidance.

Typhoon Fung Wong is already bringing "life threatening conditions" to one eastern island, with widespread disruption expected later.

The Philippines' weather bureau warned of life-threatening storm surges of up to five metres and destructive winds as Typhoon Fung-wong churns toward the country's eastern coast, where it is forecast to intensify into a super typhoon before making landfall on Sunday night.

Filipinos are bracing for the arrival of a new typhoon after one earlier this week left more than 200 people dead.

Typhoon Fung-wong is heading for the main island of Luzon, causing tens of thousands to be evacuated after another storm killed more than 200 last week.

Typhoon Kalmaegi has brought fierce winds and torrential rains to Vietnam, and left at least five people dead and thousands of homes damaged before weakening into a tropical storm
