Severe Tropical Storm Washi, known in the Philippines as Severe Tropical Storm Sendong, was a late-season tropical cyclone that caused around 1,200 to 1,500 deaths and catastrophic damage in the Philippines in late 2011. Washi made landfall over Mindanao, a major region in the Philippines, on December 16. Washi weakened slightly after passing Mindanao, but regained strength in the Sulu Sea, and made landfall again over Palawan on December 17.
