JOHOR BAHRU — Johor has activated preparedness measures to address potential water scarcity linked to the expected El Niño phenomenon, which meteorologists predict will influence weather patterns from October onwards.

State authorities have confirmed that cloud seeding exercises will be deployed if water levels at any of the state's 17 reservoirs fall below critical thresholds. The proactive approach is designed to induce rainfall during the anticipated dry period and maintain adequate water supplies for both domestic and commercial consumption.

El Niño, a naturally occurring climate pattern characterised by warmer ocean temperatures, typically reduces precipitation across Southeast Asia during affected months. Johor's dam management teams are currently conducting regular assessments of water reserves to establish optimal intervention timelines.

State water resources officials have indicated that cloud seeding operations, if activated, will be coordinated with meteorological services to maximise effectiveness. The contingency planning underscores Johor's commitment to securing reliable water supplies despite anticipated climatic challenges in the months ahead.

Residents and businesses in the state have been advised to adopt water conservation practices as a precautionary measure during the forecast dry period.
