KUALA LUMPUR: Heavy rain and thunderstorm hitting most parts of the west coast of the peninsula is not an extraordinary or extreme weather phenomenon, says Department of Meteorology Malaysia.
Its director-general Jailan Simon said the condition was due to the monsoon transition phase which usually caused heavy rain and thunderstorm over a short period in the evening or early part of the night.
“This happens each year. Besides lightning and thunder, sometimes it also brings strong winds which could cause damage to buildings or uproot trees.
“It is rather difficult to say that the current weather condition is extreme as the recent heavy rain and thunderstorm had occurred before, ” he said when contacted.
On Tuesday, flash floods hit several parts of the federal capital following heavy rain and thunderstorm in the late afternoon.
Several vehicles were damaged, causing massive traffic jams while Internet users shared visuals on the situation including damage to properties such as buildings and Ramadan bazaar stalls.
Jailan said during such situations, strong winds could reach a speed of 100kph which could cause trees to uproot and structural damage to buildings.
“Based on our forecast, the weather condition will continue for a number of days but it might dissipate by next week with the change of wind direction.
“The public and Ramadan bazaar traders and visitors should be more alert, ” he said.
Based on MetMalaysia’s long-term weather observation report, the monsoon transition phase began on March 16 and is expected to continue until mid-May, marking the end of the northeast monsoon phase since last Nov 11.
During this period, Malaysia receives weak winds from various directions, causing the formation of thunderstorms that usually hit the west coast and interior areas of the peninsula, west part of Sabah and the west and central parts of Sarawak.
This weather condition has the potential of causing flash floods and damage to weak structures. — Bernama
