 Late on January 1 , 2009 , the Joint Typhoon Warning Center ( JTWC ) reported that an area of deep atmospheric convection had persisted for the last 48 hours about 730 km ( 455 mi ) , to the southeast of Manila in the Philippines . Deep convection was developing over the northern quadrant of a weak low level circulation center . A subtropical ridge of pressure was helping to guide the disturbance and was providing good outflow as well as low to moderate vertical wind shear . However , as the disturbance was moving into a higher level of vertical wind shear the depression was not expected to develop into a significant tropical cyclone within 48 hours . During the next 48 hours the disturbance gradually developed , with the Japan Meteorological Agency ( JMA ) and the Philippine Atmospheric , Geophysical and Astronomical Services Administration ( PAGASA ) reporting early on January 3 that it had become the first tropical depression of the season , with the name Auring being assigned to the depression by PAGASA whilst it was located about 140 km ( 85 mi ) east of Surigao City on the Philippine island of Mindanao . This came after the low level circulation center had started to consolidate as deep convection was being fueled by a poleward diffluence despite being in an area of strong vertical wind shear . Over the next couple of days as Auring moved towards the east , dry air started to wrap in to its low level circulation center which started to weaken the depression after it had peaked with winds of 45 km / h , ( 30 mph ) 10 @-@ min sustained and a peak pressure of 1006 hPa / <unk> . As the baroclinic zone approached the depression late on January 5 , PAGASA downgraded the depression to an area of low pressure as the baroclinic zone was approaching the depression , as vertical wind shear had increased and outflow became hindered . However the JMA continued to issue warnings on the depression until early the next morning when the depression was declared dissipated by the JTWC and the JMA .
