PETALING JAYA: As the south-west monsoon sweeps across the country, more states will be experiencing more dry days, said the Malaysian Meteorological Department (MetMalaysia).
The south-west monsoon started on May 6 and is expected to continue until the middle of September.
The winds during this period would lead to a drier climate and less rain cloud formation, said MetMalaysia director-general Jailan Simon.
As such, dry spells are forecast to take place in many parts of the country.
“Although the south-west monsoon is characterised by low rainfall, it will still rain but with a relatively lower amount compared to other periods.
“Other than that, the rainy spell in the evenings during the south-west monsoon also normally happens briefly, just one or two hours.
“This is among the factors why the weather is still hot even though there is rain,” he said to The Star.
He said the formation of squall lines – narrow bands of thunderstorms and winds – had the potential to happen near the west of the peninsula and western Sabah in the early mornings due to wind convergence and unstable atmosphere.
This will bring hours of heavy rain, wind and thunder to some parts of Malaysia, said Jailan.
“An individual thunderstorm normally lasts an hour but the whole squall line system can last for a few hours,” he said.
