Tropical Storm Washi
Severe Tropical Storm Washi, known in the Philippines as Tropical Storm Sendong, was a late-season tropical cyclone that caused catastrophic damage in the Philippines in late 2011. Washi, which means Aquila in Japanese, made landfall over Mindanao, a major island 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.
==Meteorological history==
On December 12, the Joint Typhoon Warning Center (JTWC) noted that a developing area of low pressure had persisted about 945 km (585 mi) south-southeast of Guam. Situated along the southern edge of a subtropical ridge, the system tracked steadily westward towards the Philippines. Located within a region of good diffluence and moderate wind shear, deep convection was able to maintain itself over the circulation. Development of banding features and improvement of outflow indicated strengthening was likely. Further development over the following day prompted the JTWC to issue a Tropical Cyclone Formation Alert early on December 13. Less than six hours later, both the JTWC and the Japan Meteorological Agency (JMA) classified the system as a tropical depression, with the former assigning the identifier ''27W''. Maintaining a westward track, the depression was forecast to intensify slowly over the following three days. For much of December 13, a slight increase in shear displaced thunderstorm activity from the center of the depression, delaying intensification. By December 14, convection redeveloped over the low and the JTWC subsequently assessed the system to have attained tropical storm status.
Early on December 15, the system crossed west of 135°E and entered the Philippine Atmospheric, Geophysical and Astronomical Services Administration's (PAGASA) area of responsibility. Upon doing so, PAGASA began issuing advisories and assigned the cyclone with the local name ''Sendong''. Shortly thereafter, the storm passed close to or over Palau. By 0600 UTC, the JMA upgraded the system to tropical storm status, at which time they assigned it with the name ''Washi''. Maintaining a rapid westward track, Washi slowly became more organized, with low-level inflow improving during the latter part of December 15. On December 16, Washi reached its peak strength as a severe tropical storm and made its first landfall along the east coast of Mindanao.
After passing Mindanao, Washi weakened due to land interaction, but the storm quickly regained its strength, in the Sulu Sea. Late on December 17, Washi crossed Palawan and arrived in the South China Sea, and the system moved out of the PAR on December 18. Washi weakened to a tropical depression and dissipated on December 19, because of cool, dry air, in association with the Northeast Monsoon.
