Slow moving Typhoon Koppu slammed into the northern Philippines Sunday, killing at least one person and causing thousands to evacuate their homes.
The storm, which has weakened slightly since coming ashore, is still downing power and communication lines with powerful winds and rains that could last until Wednesday.
Tens of thousands are without power and some areas have already been overwhelmed by floodwaters. The typhoon has also disrupted flights and ferry service across the main northern island of Luzon.
Weather forecasters say Koppu will remain over Luzon for several days due to a high pressure area in the north and another typhoon in the northwest Pacific.
Forecasters predict the storm could dump 600 millimeters of rain over the next several days.
