Typhoon Mirinae (pronounced [mi.ɾi.nɛ̝]), known in the Philippines as Typhoon Santi, was the 34th depression and the 14th typhoon in the 2009 Pacific typhoon season. It came several weeks after Typhoons Ketsana and Parma devastated the Philippines, thus adding additional damage wrought by the two typhoons.
Early on October 10, 2009, the Joint Typhoon Warning Center (JTWC) reported that an area of convection was developing over an elongated and broad low level circulation center within a monsoon trough about 500 km, 315 miles to the southeast of Pohnpei. The low level circulation center was located under a region of favourable divergence, however it was located in area of moderate to high vertical windshear which was hampering the low level circulation centers attempts to organize. Over the next couple of days the vertical windshear relaxed and as a result convection started to develop further with a Tropical Cyclone Formation Alert being issued by the JTWC late on October 25 after the Japan Meteorological Agency (JMA) had designated the disturbance as a weak tropical depression.

Early on October 26, the National Weather Service Weather Forecast Office in Tiyan, Guam placed Guam, Rota, Tinian and Saipan under a tropical storm watch which meant that tropical storm force winds were possible on the islands within 48 hours. They then upgraded the watch for Rota, Tinian and Saipan to a Tropical Storm Warning as tropical storm force winds were now expected on the islands within 24 hours. These warnings and watches were kept in force until they were cancelled early the next day after the tropical depression had moved away and intensified into a tropical storm.

Throughout the Philippines, Mirinae killed 39 people and left roughly $100.1 million in damage.
Torrential rainfall produced by Mirinae in Vietnam triggered catastrophic flooding, killing at least 123 people. Roughly 2,400 homes were destroyed by swift currents and 437,300 hectares of crops were flooded. Damage was estimated to be at least 5 trillion đồng ($280 million USD).
