Tropical Depression Auring (2009)
Encyclopedia
Tropical Depression Auring formed as a tropical disturbance late on December 30, 2008, to the southeast of Manila
in the Philippines
. Over the next few days the disturbance gradually developed before early on January 3, the Philippine Atmospheric, Geophysical and Astronomical Services Administration
(PAGASA) and the Japan Meteorological Agency
(JMA), reported that the disturbance had intensified into the first tropical depression of the season with PAGASA assigning the name Auring to the depression. As the Depression was moving into a high level of vertical wind shear
, it did not develop any further and late on January 5 as the baroclinic zone approached Auring, it was downgraded to an area of low pressure by PAGASA before the JMA followed suit the next day as it was declared as dissipated by the JTWC.
Heavy rain from Auring produced severe flooding in the eastern Philippines
. Two people were killed and nine others were left missing. A total of 305 homes were destroyed and another 610 were damaged. In addition, an estimated 53 hectares (130.9 acres) of rice and 3.5 hectares (8.6 acres) of corn were damaged. About 43,851 people were affected by the depression and damages were estimated at PHP
23 million ($498,318 USD
).
(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 conslidate 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/Mbar. 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.
issued Public Storm Warning Signal #1 for Samar, Leyte
, the Camotes Islands
, Surigao del Norte
, Siargao Island
, and Dinagat Island
as winds up to 60 km/h (37 mph) were expected to affect those areas. Three hours later, Biliran Island
was also put under the warning signal. On January 4, all signals, except in Eastern Samar
, were lifted as Auring recurved and moved away from the Philippines
. The warning signal for Eastern Samar was lifted early the next day.
Heavy rains from Auring triggered flooding across the eastern provinces of the Philippines
. A total of 38,764 people were evacuated to avoid floodwaters. The rains caused the Cagayan River
to swell, leading to the death of a 12-year-old boy in Gingoog City
. In Talisay City, Cebu
, a 27-year-old woman was killed after she was electrocuted by a steel wire which was knocked down by high winds produced by Auring. Nine other people, all of whom are children, were listed as missing. About 12,211 people were left stranded at ports due to dangerous conditions caused by the depression. An additional 14 trucks, 44 light cars, 75 passenger buses, 27 vessels and 295 rolling cargoes were also stranded. Severe flooding destroyed 305 homes, 199 of which were in Macasandig. Another 610 homes sustained damage. An estimated 53 hectare
s (130.9 acre
s) of rice and 3.5 hectares (8.6 acres) of corn were damaged. About 43,851 people were affected by the storm, mainly along the Cagayan River. The remnants of Auring brought heavy rains to the flooded areas again on January 7, triggering several landslides which blocked off roads and damaging power lines, leaving parts of the Catanduanes
without power for several hours. Damages from the depression were estimated at PHP
23 million ($498,318 USD
) and an estimated 5,000 families were left homeless.
led to the issuance of a state of calamity. In addition to the state of calamity in Siargao Island, 16 villages within Cagayan de Oro City
were declared calamity areas. In the wake of Auring, the Department of Social Welfare and Development
(DSWD) provided family food packets and assistance to flooded areas, valued at PHP 372,760 ($8,120 USD). Relief funds of PHP 292,189.11 ($6,365 USD), stockpiles of food valued at PHP 77,431.2 ($1,686 USD), and non-food items valued at PHP 413,568 ($9,009 USD) were available if needed. Residents who were left homeless in Iligan City
were provided with assistance at an estimated cost of PHP 1,129,870 ($24,613 USD).
