Sarawak seeks more cloud-seeding flights as water supplies tighten
-
Sarawak wants cloud-seeding missions to continue through September whenever the weather allows, as dry conditions put dams and raw-water sources under pressure.
Deputy Premier Datuk Amar Douglas Uggah Embas said the state was discussing more frequent operations with the federal government. The request is conditional: aircraft can only seed clouds that meet the required atmospheric conditions.
The third 2026 operation ran from Sept 3 to 5 across Samarahan, Sri Aman, Betong, Kapit and Limbang. It targeted three dams — Batang Ai, Murum and Bakun — and 13 catchment areas. Uggah said previous missions had helped raise levels at Murum and Bakun, although the effect at Batang Ai was smaller.
The immediate concern is water, not a guaranteed fix for the haze. Lubau’s supply was described as critical, while operations at Awik and Spaoh had stopped. Hot weather is expected to remain a risk into October.
Cloud seeding depends on suitable clouds, humidity and wind. A scheduled window therefore does not guarantee a flight or measurable rain at a particular town.
