The Survey and Mapping Department anticipates that coastal flooding caused by the perigean spring tide phenomenon may occur as many as eight times next year in low-lying areas near the sea, particularly in Kuala Kedah (Kedah) and Kuala Perlis (Perlis).

Director of Survey for the Vertical Reference Infrastructure Section, Geodetic Survey Division, Kenidi Awang Aziz, said the projection is based on readings from the Langkawi Tide Gauge Station (Staps).
