Overview change

On December 11, a disturbance formed and stayed near Chuuk. On December 13, the low pressure area quickly got stronger. On the same day, the JTWC upgraded the low pressure to a tropical depression. They named it 27W. The JMA also upgraded it to a tropical depression. The JTWC upgraded the system to a tropical storm on December 14. They then downgraded it to a tropical depression early on December 15. The PAGASA called it Sendong as it entered the Philippine Area of Responsibility. After passing Palau on December 15, both the JTWC and the JMA upgraded the system to a tropical storm. They named it Washi. On December 16, Washi made landfall over Surigao del Sur, a province of the Philippines. Several hours later, Washi arrived at the Sulu Sea and regained its strength quickly. Late on December 17, Washi crossed Palawan, and arrived at the South China Sea. On December 19, Washi weakened into a tropical depression and dissipated.

In the Philippines, Washi caused at least 1,268 deaths. 1,079 people are officially listed as missing. Washi affected 102,899 families or 674,472 people in 766 villages in 52 towns and eight cities in 13 provinces.[1][2] Most of the deaths were in the cities of Iligan and Cagayan de Oro. Five people were killed in a landslide, but all others died in flash flooding. More than 2,000 have been rescued, according to the Armed Forces of the Philippines. Officials were also investigating reports that an entire village was swept away. The flash flooding happened overnight, following 10 hours of rain. This was made worse by overflowing rivers and tributaries. In some areas, up to 20 centimeters of rain fell in 24 hours. At least 20,000 people were staying in 10 evacuation centers in Cagayan de Oro. Officials said that despite government warning, some people did not evacuate. At least 9,433 houses were destroyed while 18,616 were damaged.[3]
