Typhoon Imbudo, known in the Philippines as Typhoon Harurot, was a powerful typhoon that struck the Philippines and southern China in July 2003. The seventh named storm and fourth typhoon of the season, Imbudo formed on July 15 to the east of the Philippines. The storm moved generally west-northward for much of its duration due to a ridge to the north. Favorable conditions allowed Imbudo to intensify, gradually at first before undergoing rapid deepening on July 19. After reaching typhoon status, Imbudo strengthened further to peak 10–minute sustained winds of 165 km/h (105 mph) on July 20. The typhoon made landfall on northern Luzon near peak intensity on July 22, but quickly weakened over land. Once in the South China Sea, Imbudo re-intensified slightly before making its final landfall in southern China near Yangjiang on July 24, dissipating the next day. In the Philippines, Imbudo was the strongest typhoon in five years, causing widespread flooding and power outages in the Cagayan Valley for weeks. Damage was heaviest in Isabela province near where the storm struck. Most of the banana crop was destroyed, and other crops sustained similar but lesser damage. Imbudo disrupted transportation across much of Luzon. Nationwide, the storm damaged or destroyed 62,314 houses, causing P4.7 billion (PHP, $86 million USD) in damage, mostly in the Cagayan Valley. There were also 64 deaths in the country. In Hong Kong, strong winds killed a man after knocking him off a platform. In China, damage was heaviest in Guangdong where the storm struck. Thousands of trees fell, and 595,000 houses were wrecked. Hundreds of canceled flights stranded travelers across the region. In Guangxi, high rainfall increased water levels in 45 reservoirs to warning levels. In Guangxi and Guangdong, collectively 20 people were killed, and damage reached about ¥4.45 billion (CNY, US$297 million). Meteorological history The origins of Imbudo were from a disorganized area of convection near Chuuk in the open western Pacific in mid-July. With weak wind shear, the system slowly became better organized. On July 15, the Japan Meteorological Agency (JMA) estimated that a tropical depression formed. The next day, the Joint Typhoon Warning Center (JTWC) issued a tropical cyclone formation alert (TCFA), noting that outflow had increased due to an upper-level low to the northeast. At 1800 UTC on July 16, the JTWC initiated advisories on Tropical Depression 09W about 665 km (415 mi) east of Yap. A subtropical
