Typhoon Durian, known in the Philippines as Super Typhoon Reming, was a deadly tropical cyclone that wreaked havoc in the Philippines and later crossed the Malay Peninsula in late November 2006, causing massive loss of life when mudflows from the Mayon buried many villages.
Durian first made landfall in the Philippines, packing strong winds and heavy rains that caused mudflows near Mayon Volcano. After causing massive damage in the Philippines, it exited into the South China Sea and weakened slightly, before managing to reorganise and restrengthen into a typhoon shortly before its second landfall, this time in Vietnam near Ho Chi Minh City, causing further damage of more than US$450 million. In all, Durian killed almost 2,000 people, Analysis: Indonesia: Earthquake - May 2006, Disaster data: A balanced perspective - Mar 2007, Analysis: Southeast Asia: Typhoon Durian - Dec 2006, Disaster data: A balanced perspective - Mar 2007 Situation Reports: Southeast Asia: Typhoon Durian - Dec 2006, Viet Nam: Typhoons Revised Appeal No. MDRVN001 Operation Update No. 3, Situation Reports: Southeast Asia: Typhoon Xangsane - Sep 2006, Viet Nam: Typhoons Revised Appeal No. MDRVN001 Operation and left hundreds more missing. Damages in the Philippines from the typhoon amounted to 5.086 billion Philippine peso (US$130 million).
On November 27, the JTWC noted that Durian could undergo explosive intensification as it moved over the Philippine Sea two days later, similar to what took place with Typhoons Cimaron and Chebi. However, there was less confidence in this scenario due to the presence of dry air west of the cyclone. On November 28, the Philippine Atmospheric, Geophysical and Astronomical Services Administration assigned the storm the local name Reming as it entered their area of responsibility. At 1200 UTC that day, the JTWC upgraded Durian to a typhoon, estimating one-minute sustained winds at . It was not until 0300 UTC on November 29 that the JMA also upgraded the storm. During the course of November 29, a westward-moving Kelvin wave interacted with Durian and provided additional convergence around the typhoon. This precipitated a period of rapid intensification as the cyclone's vorticity abruptly deepened and reached to more than in altitude. At 0530 UTC, intensity estimates using the Dvorak technique – a method of determining a tropical cyclone's intensity based on satellite appearance – yielded a raw value of 7.0, indicating one-minute sustained winds of . By this time, a clear wide eye had formed within a ring of deep convection.
Durian attained its peak intensity late on November 29 just off the coast of the Philippines with winds of and a barometric pressure of . The JTWC estimated Durian to have been somewhat stronger with one-minute winds of , making it a Category 4-equivalent super typhoon on the Saffir–Simpson scale. By the end of the rapid intensification phase, Durian turned nearly due west as a subtropical ridge built to its north. Although expected to gradually turn northwest along the southwestern periphery of the ridge, topographical effects from the Philippines were expected to limited poleward progression. Weakening somewhat, Durian brushed the southern coast of the Catanduanes early on November 30. At 0200 UTC, a weather station in Virac recorded sustained winds of and pressure. Gusts at the station peaked at before the anemometer broke. This was the highest value ever recorded in the Philippines, greatly exceeding previous record of during Typhoon Joan of 1970. Shortly thereafter, Durian made landfall in northern Albay; winds at this time were estimated at .
Interaction with land induced steady weakening of the typhoon as it moved westward over the Philippines. The storm made two additional landfalls in Quezon and Marinduque after moving over Ragay Gulf and Sibuyan Sea, respectively. Passing over the Isla Verde Passage, Durian emerged into the South China Sea early on December 1 as a minimal typhoon. During the storm's crossing of the Philippines, the area of deep convection surrounding the center expanded from 1.0 to 2.2 degrees to 2.2–3.0 degrees; however, unlike many other typhoons, the eye collapsed and failed to fully redevelop once clear of the islands. Gradual re-intensification occurred over the subsequent days, with the storm attaining a secondary peak strength of early on December 3. Influenced by flow, Durian soon turned southwestwards and began paralleling the coastline. Increasing wind shear and inflow of cooler air quickly weakened the system, with winds dropping below typhoon-force early on December 4. As Durian neared the coast of extreme southeastern Vietnam, a slight discrepancy in classification occurred between the JMA and the JTWC. While the former noted a steady weakening trend, the JTWC briefly re-classified Durian as a typhoon late on December 4.
Ultimately, Durian made its fourth overall landfall early on December 5 over the Mekong Delta south of Ho Chi Minh City with winds of . Within hours of moving onshore, a combination of land interaction and poor upper-level outflow caused all deep convection to dissipate. The system degraded to a tropical depression before emerging over the Gulf of Thailand. The depression later made landfall over Surat Thani Province, Thailand early on December 6 before crossing into the Bay of Bengal. Once over water, the circulation became increasingly well-defined and convective rainband reformed along the south side of the low. Environmental conditions were marginally favorable for development; however, Durian failed to reorganize further and degenerated into a remnant low late on December 7 as it moved just south of the Andaman Islands. The remnants continued generally westward across the Bay and later dissipated on December 9 off the coast of Andhra Pradesh, India.
The severe threat of the typhoon prompted over 1.3 million people to evacuate their homes, many of whom stayed in the 909 storm shelters. Officials advised residents in low-lying areas to seek higher grounds. School classes in Sorsogon and in Northern Samar and Eastern Samar were suspended, and many buildings opened up as storm shelters. In Naga City, about 1,500 citizens left for emergency shelters. 1,000 were evacuated elsewhere in the region, including 120 in the capital city of Manila and more than 800 in Legazpi City. The threat of the typhoon caused ferry, bus, and airline services to be canceled, stranding thousands of people for several days. All shipping traffic was halted in the Mimaropa region. The Philippine Coast Guard grounded all vessels on open waters, stranding around 4,000 ferry passengers in Quezon province. PAGASA turned off its weather radar in Virac to prevent damage.
While crossing the Philippines, Durian dropped of at Legazpi, Albay in 24 hours, including an hourly total of . The 24 hour total was the highest in 40 years for a station in the Bicol region. Heavy rainfall caused and irrigation canals to exceed their banks. Many creeks and small streams were in the Bicol region. Gusts were estimated as high as .
While the typhoon moved through the country, it caused complete in Albay, Sorsogon, Camarines Sur, and Camarines Norte, affecting tens of thousands of residents. Initially, disrupted communications prevented details about the damage in the worst struck areas. The worst of the storm effects were in Albay, Camarines Sur, Catanduanes, Mindoro, and Quezon. On Catanduanes Island, Durian destroyed about half of the houses in the capital city of Virac. The powerful winds of the typhoon blew away houses and uprooted trees, All of the trees in Bacagay were knocked down, affecting the livelihood of half of the residents. Throughout the country, about of rice fields were destroyed, accounting for 65,481 metric tons of corn; 19,420 metric tons of rice were also damaged. However, the crops were already harvested, so the storm's agriculture effects were minor. The storm also wrecked 1,200 fishing boats, severely affecting the local fishing industry, and killed many livestock.
North of Legazpi, the ash flow covered or damaged portions of the Pan-Philippine Highway. In the small barangay – small town – of Maipon, nearby streams coalesced into a valley filled with muddy waters. The landslide arrived quickly and washed away or destroyed houses in the path. Several people died while attempting to cross to higher grounds. Similar conditions affected nearby Daraga, where 149 people died. Around that city, the landslide reached deep and wide, enough to cover 3 story buildings, while floods enlarged the nearby Yawa River by 600%. About 13,000 families had to leave their homes due to the landslides. Many roads and bridges were wrecked around the volcano, which halted transportation and impacted relief work.
In Albay province alone, there were 604 deaths and 1,465 people who sustained injuries. Damage in the province totaled $71 million (USD). The storm also damaged 702 of the 704 schools in the province.
Heavy rainfall from the typhoon destroyed 22 schools and 1,120 houses in Bình Thuận Province. Strong winds from Durian blew off the roofs of about 500 houses in Bà Rịa–Vũng Tàu province. Throughout the nation, the passage of the typhoon destroyed 34,000 homes, with an additional 166,000 damaged. Typhoon Durian killed 85 in the country and injured 1,379 others. Total damages were 7.234 trillion VND (US$450 million). 2006 VIETNAM Report
On December 17, the Philippine government issued a $46 million appeal to the United Nations for financial assistance coping with Durian. This was after the country already depleted its yearly emergency funding for disasters. In response, various United Nations' departments provided about $2.6 million in emergency funding, and by late December 2006, 14 countries had provided donations to the Philippines. By the end of January, only 7.1% of the appeal was raised. By the end of April 2007, four Asian countries – China, Indonesia, Malaysia, and Singapore – donated ₱54 million (US$2.2 million) worth of emergency supplies, such as clothing, medicine, and food. Various companies and local organizations donated to the relief effort, such as medicine, food, water, transport supplies, clothes, and money. Individuals and corporations donated ₱68 million (US$1.4 million) in cash and supplies. The international response came shortly after the calamity status was declared. On December 3, Canada released $1 million (US$860,000) for local relief through its embassy in Manila and through the International Red Cross and Red Crescent Movement. Situation Reports: Southeast Asia: Typhoon Durian - Dec 2006, Philippines: Typhoon OCHA Situation Report No. 4 UNICEF donated 4,000 packages containing food, mattresses, and blankets, and UNOCHA donated $1– 2 million (USD) for relief supplies. Spain donated $250,000 (USD) and sent medical teams, medicines, food, and supplies to affected areas. Situation Reports: Southeast Asia: Typhoon Durian - Dec 2006, Philippines: NDCC media update - Typhoon "Reming" (Durian) 06 Dec 2006, 6pm The United States donated $250,000 plus supplies through the USAID program, and the Filipino community on Saipan contributed cash, food, and supplies. Australia released $1 million (US$792,000) through its AusAID program. Indonesia sent two C-130 Hercules aircraft to Legazpi City, carrying a total of 25 tonne of food, medicine, and clothing valued at 1.17 billion Indonesian rupiah (US$129,000). Japan pledged tents, blankets, generators, and water management equipment through the Japan International Cooperation Agency. Malaysia donated 20 tons of food and medicines, and Singapore sent two batches of supplies valued at $50,000 (USD) through Singapore Airlines. The Republic of Korea pledged $100,000 (USD) cash, while the People's Republic of China pledged $200,000 (USD). Israel donated $7,500 (USD), mostly in medicines and medical supplies.
The Red Cross, which responded to the repeated storms of 2006, launched an appeal that raised $9.67 million for the Philippines. In March 2009, the agency completed the missions responding to the 2006 storms and transferred the remaining funds to help repair from Typhoon Fengshen in 2008. The International Organization for Migration developed the Humanitarian Response Monitoring System in response to problems in the management of the aftermath of Durian, and also provided 12,750 metric tons of building supplies, medicine, and water in the storm's immediate aftermath. OXFAM built 242 latrines and 99 bath houses to ensure proper hygiene. The Tzu Chi Foundation set up a temporary medical camp in Tabaco to provide free health care to storm victims. The International Labour Organization built a livelihood center in February 2008 to help provide jobs to storm victims. The World Bank, in conjunction with the Philippines' National Power Corporation, funded a $21.6 million project to repair the damaged power lines in the typhoons' aftermath. The agencies also upgraded 118 electrical towers by 2008 to stabilize power supply during typhoons. As a result, there were minimal power outages during the passage of Tropical Storm Higos (Pablo) in 2008.
Beginning in January 2007, the United Nations Food and Agriculture Organization distributed about 150 packs of vegetable seeds and farm tools to displaced residents in three Bicol provinces, as part of the sustainable recovery program planned by the Philippine government for storm victims. By a year after the typhoon, farmers had regrown their rice and vegetables, utilizing a rebuilt irrigation system. The World Food Programme supplied fishermen with materials to rebuild damaged boats, allowing them to resume catching fish by May 2007. The agency also provided monthly food rations to displaced residents in Albay, totaling 294 tons of rice to about 6,000 families; however, the food distribution programs ended in December 2007, causing food shortages in the first few months of 2008 among those still displaced. UNICEF distributed 1,750 water purification tablets, along with and water containers, to ensure access to clean water.
After the successive impacts of Xangsane and Durian caused widespread , the Bicol region lost about $250 million in economic output. The unemployment rate in the Bicol region rose to about 30%, and many who retained their jobs earned less than before the storm. In the aftermath of Durian, all relief activities were coordinated through the Philippines' departments of Health and Social Welfare and Development. A fleet of over 200 vehicles transported relief supplies – food, construction materials, clothing, and medicine – to the Bicol region on December 12. The Philippine Air Force airlifted supplies and medical teams to Bicol and offshore Catanduanes, with the National Disaster Coordinating Council supplying 17,350 sacks of rice to those areas. The Departments of Social Welfare and Development and the Department of Health sent teams to help victims cope with stress and consoled the families of the deceased, aided by psychiatrists. The Department of Health also distributed tents and sleeping bags, provided vaccines to people in evacuation camps, and ensured proper burial of storm casualties. There was a minor outbreak of diarrhea in the evacuation camps that affected 142 people in Legazpi, and other evacuees were also ailed by the cold, coughing, and fever. Local governments in Albay worked to ensure areas retained clean water by using disinfectants and temporary latrines. The Philippine government provided ₱119 million (US$2.4 million) toward rebuilding the damaged schools in Albay, only 23% of the required cost to repair all of the schools.
The government assessed that about 35% of those who lost their houses had the resources to rebuild without assistance; this meant that 144,692 houses had to be rebuilt. Many of the storm victims left homeless resided in tent camps, schools, and temporary shelters, until more permanent buildings were built. The Red Cross housed about 60,000 people across ten provinces in temporary shelters. The Philippine government planned to quickly build more permanent homes, although there were difficulties in securing land and materials for the new housing. By March 2007, government and international agencies only provided 6.9% of the necessary homes, forcing people to stay in shelters longer than expected. By a year after the storm, over 10,000 families still stayed in transit camps in Albay and Camarines Sur. Various organizations helped the homeless secure housing. The government of Italy funded a ₱26 million (US$525,000) project to rebuild 180 houses in Albay. The Italian government also helped build new livelihood centers to provide jobs, provided new boats, and donated about 80,000 coconut seeds to replant trees. In the eight months after Durian struck, the Philippine National Red Cross, in conjunction with the International Red Cross, delivered building supplies to about 12,000 families to repair their homes or build new ones. The organizations encouraged residents to rebuild houses away from vulnerable areas. The International Organization for Migration, in conjunction with the United States Agency for International Development, built 907 homes and new community centers. The Philippine government released ₱76 million ($1.5 million) in funds to build 1,089 houses. UNICEF provided emergency funding to rebuild 50 daycare centers that were damaged by the typhoon. Habitat for Humanity helped repair about 1,200 homes, build about 2,000 new houses, and rebuilt four schools in Sorsogon.
Around Mayon Volcano, officials enacted search and rescue missions for victims affected by landslides. Workers quickly excavated lahar-filled valleys, bridges, and river beds to rebuild dykes. Farmers quickly regrew damaged crops, while schools and homes were cleaned and rebuilt. Stronger concrete dykes were built around populated communities. The government developed relocation plans for three landslide-prone areas in Albay. In 2011, the Regional Development Council approved a budget to construct additional dams along the Mayon Volcano to prevent the deadly floods and landslides that occurred during Durian. Dams were scheduled to be constructed around the volcano after a 1981 study, but these were delayed due to budget constraints.
PAGASA also retired the local name Reming in 2006 and replaced it with Ruby, which was also later retired following its usage in 2014. The name Typhoon Yutu has been selected by PAGASA to replace Ruby for the 2018 season, which was itself retired after the season and replaced by Rosal, which was first used in 2022.
