PETALING JAYA: Two-thirds of April will be wet in Selangor but the big question is whether the levels at the state’s seven drying dams are going to rise.
Meteorological Department central forecasting office director Muhammad Helmi Abdullah said an average of 150mm to 250mm of rainfall was expected in Selangor this month.
“The number of rainy days will be about 20.
“But we feel this month will be slightly below average (in terms of rainfall),” he said, adding that the average for this month was about 300mm.
It is not known if rain forecasted this month will fall in catchment areas served by the Sungai Selangor dam, which is the state’s largest.
Experts and government officials have noted that a lot of the rain did not fall in catchment areas served by dams in the state.
A total of 65mm of rain was recorded in Petaling Jaya over a 24-hour period from 8am on Friday.
It was reported that 200mm of rainfall was needed for the dam to rise to a 55% capacity, considered as the safe level to cease water rationing and resume regular supply to 6.7 million consumers.
During the 24-hour period from 8am on Friday only 5.35mm poured into the Sungai Selangor dam.
The level at the dam, which serves 60% of the entire state besides Kuala Lumpur and Putrajaya, has been hovering around the 37% mark over the past few days.
The level was 37.66% as of 8am yesterday, a mere 0.07% increase from the previous day.
