Typhoon Utor was blamed for heavy rains of up to 350 mm within 24 hours in southern Peninsular Malaysia, specifically Johor, Negeri Sembilan, Melaka and Pahang, causing massive floods within the southern region on December 18, 2006, which was considered as the worst in the Malaysian southern region history. 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 by land after all main roads leading to those towns were all flooded. Until December 24, 2006, the floods had claimed 8 lives.
