Typhoon Neoguri (international designation: "0801", JTWC designation: "02W", PAGASA name Ambo, Chinese: 台风浣熊) was the earliest tropical cyclone on record to strike The People's Republic of China. The first named storm in the 2008 Pacific typhoon season, named after the Korean word for raccoon dog, it formed from a low pressure area on April 13 to the east of the Philippine island of Mindanao, and after crossing the island it intensified into a tropical storm in the South China Sea. Environmental conditions allowed for quick strengthening, with Neoguri attaining typhoon status on April 16. The typhoon reached its peak intensity on April 18 as it approached the island of Hainan, and subsequently it turned northward. Due to increased wind shear and cooler waters, Neoguri rapidly weakened and made landfall as a minimal tropical storm in southern China on April 19.

In the southern Philippines, the storm brought heavy rainfall, which left a person missing when a boat capsized. The typhoon left 40 fishermen missing in the South China Sea. Neoguri brought heavy rainfall as it made its final landfall on China, causing moderate damage totaling over ¥296 million (2008 RMB, $42 million 2008 USD). Three deaths occurred in China.

Meteorological history

An area of disorganized convection persisted east-northeast of Palau on April 11 in association with a sharp easterly wave, and within the system, a low pressure area was evident between Palau and Yap. Located beneath a developing anticyclone, with limited wind shear and enhanced . [http://i28.tinypic.com/20szxnl.jpg]

The depression continued westward, along the southern periphery of a strong subtropical ridge extending from southeastern Asia to north of Luzon. After it entered the Sulu Sea, the convection and circulation continued to consolidate, while its anticyclone aloft provided excellent outflow. Based on satellite intensity estimates using the Dvorak technique, the JTWC upgraded the depression to Tropical Storm 02W midday on April 14.

After attaining tropical storm status, significant intensification was limited due to a slight increase in wind shear as well as impeded outflow.

Typhoon Neoguri underwent an eyewall replacement cycle around the time it reached peak intensity; the inner eyewall collapsed, and the outer eyewall contracted to a diameter of 65 km (40 mi). Upon attaining peak winds, the typhoon had turned northward, [cite web|author=Delta Forecast Team|year=2008|title=Typhoon Neoguri Prognostic Reasoning Warning NR 017|publisher=Joint Typhoon Warning Center|accessdate=2008-04-18|url=ftp://ftp.met.fsu.edu/pub/weather/tropical/GuamStuff/2008041803-WDPN.PGTW] and the China Meteorological Administration assessed Neoguri as moving ashore along Hainan island near Wenchang.cite web|author=Du Guodong|date=2008-04-19|title=Typhoon Neoguri disrupts air and sea traffic in Hong Kong|publisher=Xinhua|accessdate=2008-04-19|url=http://news.xinhuanet.com/english/2008-04/19/content_8011442.htm] However, other agencies assessed the typhoon as tracking parallel to the eastern coastline just offshore. Land interaction and wind shear weakened the typhoon, [cite web|author=Delta Forecast Team|year=2008|title=Typhoon Neoguri Prognostic Reasoning Warning NR 019|publisher=Joint Typhoon Warning Center|accessdate=2008-04-18|url=ftp://ftp.met.fsu.edu/pub/weather/tropical/GuamStuff/2008041815-WDPN.PGTW] and by April 19 it had weakened to a tropical storm. Cooler waters contributed to further weakening, causing its convection to diminish significantly and for its circulation to become elongated.

Preparations and impact

As Ambo (Neoguri) passed directly through many parts Visayas and Mindanao, PAGASA issued Public Storm Warning Signals for these areas. Signal number one was issued for southern Negros, southern Cebu, Bohol, Southern Leyte, Siquijor and . [http://i26.tinypic.com/124hg0i.png]

As a tropical depression, Neoguri (Ambo) brought heavy rainfall to many portions of the Philippines, including even Metro Manila [http://www.gmanews.tv/story/89236/Ambo-brings-early-morning-rains-to-Metro] . In Cebu City, the precipitation caused flooding, which forced 62 people to evacuate their houses.

In preparation for the storm, about 21,800 fishing boats in the Chinese province of Hainan returned to port, [cite news|author=Amber Yao|date=2008-04-17|title=South China braces for typhoon Neoguri|publisher=Xinhua|accessdate=2008-04-17|url=http://news.xinhuanet.com/english/2008-04/17/content_7996977.htm] and about 120,000 people evacuated from fish farms and low-lying areas on the island. Officials halted ferry service between Hainan and the Leizhou Peninsula in Guangdong province.

The eighteen missing fishermen were found thirty hours after Neoguri struck. The ship they were on had sunk, and the crew clung to debris and made makeshift rafts to survive in the waters. However, another 18 Chinese fisherman and 22 Vietnamese fisherman remain missing.

Along the mainland, ferry service was temporarily stopped between Hong Kong and Macau. At the Hong Kong International Airport, over 200 flights were delayed due to the threat of the storm; additionally, around 30 were canceled, and 66 others were deviated elsewhere.
