Waves are expected to be the highest in October and November with a forecast reading of between 5.5m to 5.6m
Residents living along the coastal shores of Sarawak and Sabah, as well as the peninsula states, have been told to be on the alert for high waves that may cause flash floods.
The National Disaster Control Centre in Putrajaya have issued a warning that sea waves may reach 4.8 metres to 4.9 metres.
The warning said this surge in tidal waves will be expected from today (Oct 10) until Oct 12.
A circular was issued by the centre to all relevant state agencies about the impending surge in sea-tides.
The National Disaster Control Centre had called on all state agencies like Bomba, District Offices, Drainage and Irrigation Department to be on alert for any eventualities.
Residents and motorists along the Bintulu-Miri coastal shore had a king tide scare.
It came hours before the National Disaster Control Centre in Putrajaya issued a warning that high tides may cause floods.
A king tide is a term used to describe exceptionally high tides.
The incident happened in Tanjong Kidurong in the Bintulu district of northern Sarawak.
Between 10th and 12th October, a surge in tidal waves as high as 4.8 to 4.9 metres is expected to cause widespread floods.
Residents in coastal areas here have been cautioned to be prepared for possible flooding due to a rise in sea levels caused by big waves due to high tides.
Selangor Disaster Management Unit head Ahmad Fairuz Mohd Yusof (pic) said the large waves were expected to occur between Sept 21 and Dec 5.
“The occurrence in the coastal areas in Selangor such as the Klang district, Kuala Langat, Sepang, Kuala Selangor and Sabak Bernam are expected to be affected,” Ahmad Fairuz told a press conference at the state secretariat on Wednesday.
He said the waves are expected to be the highest in October and November with a forecast reading of between 5.5m to 5.6m.
Ahmad Fairuz said the situation can worsen if there was rain and strong winds during the waves.
“If the wave is accompanied by rain and heavy winds, there is a possibility of sea water overflowing the coastal banks.
“This will erode the banks, causing them to break and if this happens the increased level of sea water flowing into land will flood high risk areas such as fishing villages and jetties,” he added.
He said, as opposed to rain water flooding, sea water flooding will cause more damage due to the salt content.
