Part of the 2006 Pacific typhoon season

Typhoon Utor, known in the Philippines as Typhoon Seniang,[1] swept through the central Philippines in December 2006, exacerbating the damage left behind by previous Philippine typhoon strikes that year. Residual moisture from the tropical cyclone indirectly contributed to extensive flooding in Malaysia. Utor originated from an area of disturbed weather that organized into a tropical depression on December 7 west-southwest of Yap. The cyclone steadily progressed westward while gradually intensifying, reaching tropical storm intensity late on December 7. On December 9 and the ensuing two days, Utor crossed the central Philippines and reached typhoon strength before weakening somewhat upon entry into the South China Sea. Reintensification ensued afterwards, and Utor reached its peak intensity on December 13 with maximum sustained winds of 155 km/h (100 mph) shortly after regaining typhoon strength.[nb 1] However, wind shear and dry air began to take its toll on Utor thereafter, quickly weakening the storm until its dissipation on December 15.

Due to the destruction wrought by Typhoon Durian just weeks prior, preparations began in earnest in the Philippines. Over 91,000 people were evacuated from areas at risk, primarily from Albay. Two major summits to be held in Cebu were postponed as a result of the forecast inclement weather. In addition, recovery efforts for victims of Durian had to be suspended and all domestic flights in the Philippines were cancelled. Utor's impacts in the central Philippines were extensive, with 30 casualties reported and the damage toll reaching US$15.8 million.[3] Widespread power outages affected the entirety of Eastern Visayas. Numerous ships sunk as a result of rough seas generated by the typhoon, including a ferry carrying 104 passengers and crew. Following the storm, relief agencies began to allocate resources to those affected by the typhoon, in turn also adding to relief efforts for the three Philippine typhoons which preceded Utor. Precautionary efforts also took place in Vietnam, Thailand, and Malaysia, while the Paracel Islands sustained marked damage but no fatalities. Although the storm mostly dissipated in the South China Sea, Utor's remnant moisture later contributed in part to Peninsular Malaysia's worst flood event in recorded history, as copious amounts of precipitation fell over a short, four-day period. Eight people were killed by the floods which were worst in Kota Tinggi and Segamat District.
