What is Risk Analysis in the Context of Natural Disaster Events
Risk analysis for natural disasters assesses hazard likelihood, exposure and consequences to people, infrastructure and business operations. For flood and landslide events this includes hydrometeorological forecasting, river-catchment vulnerability, infrastructure fragility and social exposure. Historical November–December flood seasons in Malaysia demonstrate rapid escalation from heavy rain to multi-day riverine flooding and evacuations; this context informs current preparedness and continuity planning.
Executive Summary
- Date of Event: 24 November
- Location: Selangor, Perak, Penang, Sarawak and affected districts nationwide
- Risk Category: Natural Disasters
- Severity Score: 4 / 5
- Confidence Level: 78 %
Widespread flooding has produced 10,750 reported victims across multiple states. Antecedent saturation, ongoing heavy-rain advisories and reservoir management increase the likelihood of additional inundation and dam spill releases. Forecasted active window: next three to ten days for emergency operations, with recovery extending two to four weeks in worst-hit districts. Primary concerns are life-safety, road and bridge closures, prolonged utility outages and supply chain interruption.
Current Updates
Authorities report active evacuation centres and continuing heavy-rain warnings. River basins and dam discharge notices remain critical watchpoints. Relief and state emergency teams are mobilised; monitor MetMalaysia, DID and NADMA advisories continuously.
Known Hotspots and Sensitive Areas
High Impact: Coastal and riverine districts of Kelantan and Terengganu (historical precedence), low-lying urban wards in Kota Bharu and Temerloh, and coastal corridors on Federal Route 3
Medium Impact: Selangor lowlands, Perak riverine settlements and Penang low-lying districts; logistic nodes and port access may be intermittently affected.
Low Impact: Interior highlands with localized landslide risk in steep catchments.
Northeast-monsoon convective bands exacerbate flood risk in November–December.
Impact on Transportation and Services
Road closures on Federal Route 3, state arteries and affected East Coast Expressway sections will delay freight and passenger movements. Inter-state bus services and small ports may be suspended; last-mile deliveries will face 12–72-hour delays. Utilities (power, water) show localized outages; telecommunications may suffer intermittent degradation in hardest-hit towns.
Recommended Actions
Immediate:
- Conduct staff census across affected states
- Suspend non-essential travel
- Activate evacuation and shelter-in-place protocols
- Move critical inventory and IT assets to higher floors or alternate sites
Operational:
- Reroute logistics away from coastal corridors, pre-stage relief shipments, failover IT systems to cloud/DR sites
- Communicate service impacts to customers
- Liaise with NADMA, DID and local authorities for access permits and situational updates
Multidimensional Impact
Humanitarian needs (shelter, medical) increase burden on local relief capacity; prolonged transport disruption will affect FMCG, construction materials and cold-chain suppliers; insurance and regulatory reporting demands will rise.

Final Thoughts
Flood trajectory remains conditional on further rainfall and reservoir operations. Primary watchpoints: river gauge rises, dam discharge notices and road closure bulletins. Businesses must prioritise people safety, enact contingency logistics and preserve critical IT operations. Early warning, rapid evacuation and coordinated stakeholder communications will materially reduce health and continuity impacts.
