Operational Context
Southern Thailand is experiencing extensive flooding driven by intense rainfall, overwhelmed drainage systems and rapid urban inundation across key economic and residential zones. Songkhla and Hat Yai remain the highest-risk areas, with widespread displacement, business closures and strain on local emergency services. Flood depth, duration and exposure closely resemble previous major monsoon events from 2019–2024, where prolonged waterlogging and delayed drainage significantly disrupted mobility, SMEs, tourism and logistics operations.
Executive Summary
- Event Date: 25 November
- Location: Nakhon Si Thammarat, Phatthalung, Songkhla, Southern Thailand
- Risk Category: Environment
- Severity Level: 4 / 5
- Confidence Score: 78%
Severe rainfall has caused major flooding across southern Thailand, resulting in at least thirteen casualties, stranded residents, widespread road damage, and cancellations of Bangkok–Hat Yai flights. Disruption is likely to persist for three to ten days in worst-hit areas, with recovery extending two to four weeks for commercial districts. High risks include people safety, mobility delays, business closure, and utility outages.
Known Hotspots & Sensitive Zones
High Impact: Hat Yai city centre, Kim Yong Market area, Songkhla commercial districts, SEA Games 2025 venues, hotel clusters
Medium Impact: Mitraphap/Route 43, Sadao–Sathing Phra connectors, rural bridges
Low Impact: Inland highlands and peripheral retail corridors
Repeated monsoon-season flooding in this region reflects low drainage capacity and recurring high-intensity rainfall patterns.
Impact on Transportation & Services
Road closures affect Hat Yai’s major arteries, while Songkhla-bound logistics face delays or stoppages. Bangkok–Hat Yai flights from 26–30 November are cancelled, and rail and intercity buses report significant delays. Utility outages, like power cuts, contaminated water supply and sewage overflow, are reported in multiple urban districts. Business operations face multi-day shutdowns, reduced staff availability and delayed deliveries.
Recommended Action
- Activate local Incident Response Teams for all southern Thailand operations.
- Relocate critical assets to higher ground, disconnect electrical systems and shift digital infrastructure to cloud-based disaster recovery platforms.
- Suspend nonessential travel; mandate shelter-in-place or evacuation based on authority guidance.
- Reroute shipments to functioning hubs (e.g., Surat Thani), prioritise critical goods and deploy high-clearance logistics vehicles.
- Issue immediate customer and regulator notifications with safety instructions, service delays and contact points.
Multidimensional Impact
Flooding threatens SEA Games 2025 schedules, disrupts tourism travel and increases relief-related fiscal burdens. Emergency deployments may affect ongoing regional development programs. High-profile rescue incidents elevate security monitoring and can influence stakeholder confidence and insurance claims.

Situational Outlook
Flooding is most likely to stabilise within seventy-two hours under the baseline scenario, with gradual improvement in water levels and partial reopening of major corridors. A moderate escalation remains possible if drainage systems fail or additional rainfall occurs, potentially extending inundation for up to seven days and prolonging transport and service disruptions. In a severe escalation, prolonged heavy rainfall or major infrastructure damage could trigger widespread inundation across Songkhla and Hat Yai, resulting in multi-week recovery timelines and extensive operational impact.
Strategic Takeaway
Flood-related disruptions will continue to challenge mobility, service delivery and local economic activity. Early planning, coordinated communication and alternate routing remain critical for continuity. Businesses should strengthen preparedness, adopt proactive monitoring and leverage early warning tools such as MitKat’s Datasurfr to anticipate evolving environmental risks.
