What’s the difference of thunderstorm warning level issued by the Malaysian Meteorological Department?
On October 3, our nation will enter the monsoon alternation phase, and during this time, there will be a lot of afternoon and evening thunderstorms. After a thunderstorm, low-lying areas are susceptible to lightning floods.
