Meanwhile, the Timah Tasoh, Malut, Teluk Bahang and Sembrong Barat dams in Perlis, Kedah, Penang and Johor, respectively, are on alert with their water levels currently being between 41% and 50%.

The agency said the health ministry has received 53 cases of illnesses related to the hot weather, comprising 29 cases of heat exhaustion, 19 people with heat cramps and five suffering from heat stroke.

“No new deaths have been recorded. This means that there has only been one death from heat stroke, which was reported on April 25,” it said in a statement.
