Moisture associated with Utor was partially blamed for heavy rains which produced extensive flooding in Peninsular Malaysia; these floods were the first in a long string of flood events that would plague the region until February 2007. The tropical moisture acted in tandem with wind shear and a monsoonal flow to produce continuous precipitation over the Malaysian states of Pahang, Johor, and Malacca. Rainfall peaked at 567.8 mm (22.35 in) in Bandar Muadzam Shah over a four-day period, with similar rainfall totals occurring elsewhere. These floods were considered the worst in the history of southern Malaysia. The worst-affected areas were Segamat and Kota Tinggi, where both towns were inaccessible by land after all main roads leading to those towns were flooded. Eight fatalities resulted from the historical flooding.
