The 2006–2007 Southeast Asian floods were a series of floods that mostly affected Malaysia from 18 December 2006 to 13 January 2007. The floods were caused by above average rainfall, which was attributed to Typhoon Utor (2006) which had hit the Philippines and Vietnam a few days earlier. By the third week of January 2007, Johor had been affected by a larger flood. Singapore and certain parts of Indonesia were flooded due to the same typhoon. Throughout the week starting 18 December 2006, a series of floods hit Johor, Malacca, Pahang and Negeri Sembilan. During this period, these southern Malaysian states, along with Singapore, experienced abnormally high rainfall which resulted in massive floods. The rainfall recorded in the city of Johor Bahru on 19 December amounted to 289mm compared to the average annual rainfall of the city which is 2400mm. In Singapore, the 24-hour rainfall recorded on 20 December was 366 mm, the third highest recorded rainfall in 75 years. The flooding began when torrential downpours since Sunday caused rivers and dams to overflow. Weather officials described the flooding as the worst in the area in a century. At least six people died. Later that week, beginning 22 December, North Sumatra experienced abnormally high rainfall which also caused flooding. Causes Typhoon Utor was blamed for heavy rains of up to 350 mm within 24 hours in southern Peninsular Malaysia, specifically Johor, Negeri Sembilan, Malacca and Pahang, causing massive floods within the southern region on 18 December 2006, which were considered as the worst in the history of the southern region of Malaysia. However, there were also reports a few days earlier that adverse weather was not to be blamed on the typhoon. The worst-affected areas were Segamat and Kota Tinggi, where both towns were totally inaccessible via land transport routes after all main roads leading to those towns were flooded. As of 4 January 2007, the floods had claimed 15 lives. Heavy rains were expected in Penang, Perak, Kelantan and other states in the northern region during this period. Areas affected Indonesia The floods affected areas such as Aceh and North Sumatra, leaving many homeless. The floods lasted for a week starting on December 22. An estimated 400,000 people were displaced at the peak of the flooding with at least 118 people dead and 155 people missing as of 29 December 2006.
