Thunderstorm alert for KL, Selangor, multiple other states

Severe Thunderstorm Alert Issued Across Kuala Lumpur, Selangor and Multiple Malaysian States

A severe weather alert has been issued across several parts of Malaysia as authorities warn of incoming thunderstorms, heavy rainfall, and strong winds expected to impact multiple regions nationwide.

According to the Malaysian Meteorological Department (MetMalaysia), the thunderstorm warning remains in effect until 6:00 PM today, with dangerous weather conditions forecast to develop progressively throughout the afternoon.

Areas Affected

In Peninsular Malaysia, the northern region is among the first expected to experience severe weather. The alert covers several districts in Kedah and Perak, along with the entire state of Penang.

The central region is also on high alert, including:

• Kuala Lumpur
• Selangor
• Putrajaya
• Parts of Pahang

Further south, the warning extends to Negeri Sembilan and Melaka, as well as most districts in Johor, where thunderstorms and intense rainfall are forecast to occur.

On the east coast, several areas in Kelantan and Terengganu are also expected to face similar storm conditions.

East Malaysia Also Impacted

The warning is not limited to Peninsular Malaysia. In East Malaysia, storm risks have been identified in:

• Limbang division in Sarawak
• Interior regions of Sabah
• Tawau division
• Kudat division

Authorities say the widespread coverage reflects unstable atmospheric conditions affecting multiple weather systems simultaneously.

Rainfall Intensity and Storm Criteria

MetMalaysia issues thunderstorm alerts when weather monitoring systems detect rainfall intensity exceeding 20 millimetres per hour, especially when storms are expected to persist for more than one hour.

Such conditions can trigger:

• Flash floods
• Sudden road inundation
• Falling trees
• Traffic disruptions
• Power outages

Urban areas like Kuala Lumpur and Selangor are particularly vulnerable due to dense infrastructure and drainage limitations.

Public Safety Advisory

The meteorological department has urged residents in affected regions to remain vigilant and take precautionary measures, including:

• Avoiding open areas during lightning storms
• Delaying outdoor activities
• Monitoring official weather updates
• Exercising caution while driving in heavy rain

Local disaster management agencies are also o

Seasonal Weather Pattern

Malaysia is currently experiencing an inter-monsoon transition phase, a seasonal period commonly associated with:

• Isolated thunderstorms
• Short but intense rainfall bursts
• Strong gusty winds

Weather experts note that storms during this phase tend to develop rapidly in the afternoon and evening due to heat-driven atmospheric instability.

While no casualties or major disasters have been reported in connection with the latest alert, authorities stress that early warnings are crucial to minimizing risks and ensuring public safety.
