Selangor authorities have urged residents in low-lying and coastal areas to remain vigilant as a high tide phenomenon is forecast to push water levels up to 5.2 meters on Sunday, Nov. 8, 2026. The warning comes as heavy rains trigger flash floods in neighborhoods like Kampung Melayu Subang.
High Tide Warnings Across Port Klang
Exceptionally high tides are forecast in Port Klang from Nov. 7 through Nov. 11, 2026, according to the Klang District Disaster Management Committee. The committee’s advisory indicates that the peak water level of 5.2 meters is expected at 5:02 a.m. on Sunday, Nov. 8, placing the readings firmly within the warning category of 5.0 to 5.3 meters.
Additional peaks are scheduled during the five-day advisory window. Sea levels are projected to reach 5.1 meters on Saturday, Nov. 7, at 4:23 a.m., and match that 5.1-meter mark again on Monday, Nov. 9, at 5:37 a.m. The readings will hit 5.1 meters on Tuesday, Nov. 10, at 6:08 a.m., before dropping down to 5.0 meters on Wednesday, Nov. 11, at 6:37 a.m.
Convergence of Rain and Seawater in Selangor
The Selangor Fire and Rescue Department warns that water flows from the Sungai Buloh and Ijok areas could converge with the incoming high tide, increasing flood risks in low-lying coastal zones such as Kuala Selangor. Selangor Fire and Rescue Department operations assistant director Ashrul Riezal Asbar stated that the forecast relies on projections from the Irrigation and Drainage Department, noting that water levels in Klang already reached 5.1 meters on Saturday, Nov. 7.
Klang mayor Datuk Abd Hamid Hussain issued a statement emphasizing that the combination of high tides and afternoon thunderstorms prevents rainwater from draining effectively. When seawater pushes up rivers and local drains, low-lying land floods faster. Klang Royal City Council officials advise motorists and residents to avoid flooded stretches, monitor weather updates closely, and prepare early if they live in vulnerable zones.
Flash Floods Hit Kampung Melayu Subang
While the statewide high tide alert looms, localized downpours have already caused disruptions. Social media posts showed Kampung Melayu Subang hit by flash floods following heavy rain on Saturday afternoon, inundating residential areas and submerging parts of residential compounds and access roads.
Ashrul Riezal clarified that the rising water levels in Kampung Melayu Subang were caused by an overflow from the local drainage system rather than the high tide phenomenon itself. Threads user Nurul Azuwana claimed that water levels rose after only about 20 minutes of rain, while another user, hyenarawr1, claimed it was the third flash flood to strike the area that week. Those incidents follow a Nov. 2 event where roughly 92 houses across Lorong Merbau, Jalan Cengal, Jalan Resak, and Jalan Jati suffered flooding.
