Separately, MetMalaysia director-general Muhammad Helmi Abdullah said that lower rainfall is expected to occur in most places during the upcoming southwest monsoon from May 15 until September 2023.
“During the southwest monsoon, the wind usually blows consistently from the southwest with lower air humidity and more stable atmospheric conditions … (leading to) less cloud formation.
“As a result, most places throughout the country will experience more days without rain than days with rain,” said Mr Muhammad Helmi in a statement issued on Tuesday.
He noted that uncontrolled open burning may lead to haze during the monsoon, particularly from July to September.
“As such, open burning must be avoided to reduce the effects of haze and environmental pollution,” he said, adding that the public is also advised to use water sparingly throughout this period.
Mr Muhammad Helmi added that heavy rains with strong winds and lightning will still occur especially in the early morning in the west coast of the peninsula and west Sabah following the formation of squall lines.
A squall line is a fast-moving system of thunderstorms that form in a long, narrow line as a result of intense wind which can last up to several hours.
According to a report by The Star last month, MetMalaysia had forecast the temperature to hover at about 35 degrees Celsius in most parts of the country daily until early May.
