Malaysia: Red rain warnings issued for Kelantan and Terengganu through Dec. 30

Officials have issued red (highest level) and orange (second highest level) continuous rain warnings for Kelantan and Terengganu states through at least Dec. 30. The warning coincides with ongoing localized flooding in the area that has resulted in the evacuation of hundreds of people. The warnings and rainfall coincide with the region's northeast monsoon period (running through April).

Heavy downpours, flooding, and landslides could affect business, transport, and utility services in many areas. The potential for flooding is highest in low-lying communities near watercourses. Urban flooding is possible in areas with poorly maintained, inadequate, or non-existent drainage systems. Landslides and mudslides are possible in hilly and mountainous areas.

Floodwaters and debris flows may render some bridges, rail networks, or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters. Severe weather could also trigger flight delays and cancellations at domestic and international airports.
