Tropical storm Ketsana strengthened to a typhoon as it headed across the South China Sea after leaving more than 100 people dead in the Philippines and is forecast to hit the coast of Vietnam Tuesday.

Ketsana’s winds are expected to strengthen to 139 kph within 24 hours, the center said. It’s forecast to cross the coast southeast of Hue late Tuesday.

The storm left at least 103 people dead in the Philippines when it crossed Luzon two days ago, causing floods in the capital, Manila, that forced thousands to evacuate their homes.

Ketsana is the name of a tree in Laos, according to the Hong Kong Observatory, which list names in use for Pacific storms on its website.
