Residents in the Philippines are bracing for another powerful storm expected to dump massive amounts of rain over the same area just flooded by Typhoon Nerat.

Forecasters say the new storm, Typhoon Nalgae, will hit the main island of Luzon Saturday morning. They say Nalgae has intensified rapidly and now bears winds of more than 200 kilometers per hour.

Officials are warning residents to be take precautions and stay alert to the storm's progress.

More than 40 people were killed and 30 more remain missing after Nerat tore through the region this week. The storm downed trees and caused huge waves that crashed over seawalls in Manila, flooding a hospital, several businesses and the U.S. embassy.

Heavy rains also caused widespread flooding that has yet to recede in some areas.
