Typhoon Nuri, known in the Philippines as Typhoon Karen, was the 12th named storm and the seventh typhoon that was recognised by the Japan Meteorological Agency. The Joint Typhoon Warning Center recognised it as the 13th tropical depression, the 12th tropical storm and the 8th typhoon of the 2008 Pacific typhoon season. The name Nuri was submitted to the World Meteorological Organisation's Typhoon Committee by Malaysia in 2003 after the name Rusa was retired in 2002. The name Nuri is Malay for a blue crowned parroquet, a type of parrot. The name Karen was assigned by PAGASA to a tropical depression for the second time, the other time being in 2004 to Typhoon Rananim. Typhoon Nuri formed as a tropical depression on August 17 with the JMA then designating it as Tropical Storm Nuri the next day. It reached typhoon status later that day. Nuri then made landfall in the Philippines as a typhoon on August 20 leaving at least 10 people dead and 11 injured. Nuri then emerged into the South China Sea the next day and started moving towards Southern China. As Nuri moved closer towards Hong Kong, the Hong Kong Observatory issued its Increasing Gale or Storm Signal No. 9 for the first time since Typhoon Dujuan in 2003. Typhoon Nuri then made a direct hit on Hong Kong as a typhoon. The JMA issued its final warning on August 23 as Typhoon Nuri was moving into Southern China.
Meteorological history
Early on August 16 a tropical disturbance developed in the northwestern Pacific Ocean to the northeast of Guam. It was initially forecast that it would not develop into a tropical cyclone by the Joint Typhoon Warning Center, but later that day the JTWC forecast for it to become a tropical cyclone within 24 hours and so issued a Tropical Cyclone Formation Alert. On August 17 the disturbance became more organized and intensified into a tropical depression when it was located to the east of the Philippines. The JTWC designated it as 13W. Later that day both the JMA and PAGASA identified the tropical depression and started to issue full advisories on the depression with PAGASA assigning the name Karen to the depression. The depression then rapidly intensified into a tropical storm with the JTWC upgrading it that day whilst the JMA and PAGASA did so the day after. When the JMA designated the depression as a tropical storm it was assigned the name Nuri and the international designation of 0810 by the RSMC in Tokyo. This rapid intensification continued with the JMA designating it as a severe tropical storm on August 18; then they, along with JTWC and PAGASA, upgraded it to a typhoon. Late on August 19 Nuri made its first landfall on the coast of Cagayan Province in northern Luzon. Nuri then entered the Babuyan Channel early the next day and started to move northwestwards towards the southeastern coast of China. On August 21 PAGASA released its final advisory on Typhoon Karen as Nuri moved out of its area of responsibility and moved towards Hong Kong. The JMA then downgraded Nuri to a severe tropical storm with the JTWC also downgrading Nuri to a tropical storm later that day. The JMA did not downgrade Nuri to a tropical storm until the next morning when Nuri had made a rare direct hit on Hong Kong. The JTWC then issued its final advisory on Nuri and the JMA then downgraded Nuri to a weak tropical depression early the next day and issued its last full advisory on Nuri just as it was moving into the Chinese mainland.
Preparations
Philippines
PAGASA issued Public Storm Warning Signals 1 to 3 all across Northern and Central Luzon. The areas initially issued of Storm Signal number 1 are the Cagayan and Isabela provinces. However, as the storm tracked nearer to Cagayan, more areas were put under storm signals 1, 2 and 3. PAGASA issued warnings on Karen until 21 August. On August 19 the National Disaster Coordinating Council proclaimed suspension of classes on the 19th and 20 August for the following regions: Central Luzon, Ilocos region and National Capital Region as PAGASA had forecast that these regions would be affected by Typhoon Karen.
Hong Kong
On August 20 as Typhoon Nuri moved away from the Philippines towards southern China, The Hong Kong Observatory issued the Standby Signal No. 1 as Typhoon Nuri was centred within 800 kilometres of Hong Kong. Late the next day the HKO issued the Strong Wind Signal No. 3 as Typhoon Nuri had tracked closer towards Hong Kong. On August 22, the HKO issued the Northwest Gale or Storm Signal No. 8 at 07:40. Later that day at 13:40 the HKO hoisted the Increasing Storm Signal No. 9 at 13:40 The HKO then warned that they would be forced to hoist their first Hurricane Signal No. 10 since Typhoon York in 1999 if Nuri maintained its strength. However, as Nuri had weakened slightly, the HKO did not need to issue their highest wind signal. The HKO kept the Increasing Storm Signal No. 9 stayed in force for 11 hours, which is longer than any other No. 9 signals on record. Before they lowered it to the Southwest Gale or Storm Signal No. 8 on August 23 which was in force for 2 hours before it was downgraded to the Strong Wind Signal No. 3 and was downgraded to the Standby Signal No. 1 signal at 09:40. All signals were cancelled at 11.15 am
