This report evaluates potential impacts across travel, safety, business continuity, and infrastructure, supported by scenario analysis, past incident comparisons, and emergency response recommendations. Ideal for business continuity planners, crisis managers, and regional risk analysts operating in the Philippines.
Introduction
Metro Manila experiences seasonal monsoon rains that frequently lead to localized flooding, affecting both public and private sector operations. The 03 July 2025 incident in Quezon City is part of an annual trend of weather-induced disruptions that affect business continuity, supply chains, and safety, especially in low-lying and densely populated urban pockets.
What is Risk Analysis in the Context of Monsoon Floods?
Risk analysis for monsoon flooding involves evaluating the impact of heavy rainfall on public safety, infrastructure, business continuity, and urban mobility. These assessments help organizations and authorities prepare for seasonal events that may not be extraordinary in intensity but pose recurring operational risks.
Executive Summary: Moderate Risk Level
- Date of Incident: 03 July 2025
- Location: Barangay Roxas District, Quezon City, Metro Manila, Philippines
- Risk Category: Natural Disasters
- Severity Score: 3/5
- Confidence Level: 90%
Localized flooding due to monsoon rains has caused temporary mobility and operational disruptions in Metro Manila, particularly in Quezon City. With rainfall expected to continue intermittently through the season, residual flooding and logistical impacts are expected to last for up to 72 hours.
Known Hotspots and Sensitive Areas
- España Boulevard and the University Belt – prone to deep flooding
- C5 Road, Quezon Ave, and EDSA underpasses – frequently impassable
- Quezon City Hall and surrounding residential communities – sensitive to runoff and stormwater accumulation
- Hospitals (e.g., PGH, NKTI) – vulnerable due to access issues during sustained flooding
Impact on Transportation and Utilities
- Road Disruption: Major road closures including parts of EDSA, España Blvd, Taft Avenue, Quezon Ave, and C5.
- Public Transport: Rerouting of buses and jeepneys; MRT/LRT delays possible due to weather or minor flooding at station entry points.
- Utility Damage: Localized electricity outages and water contamination expected; disruption to services by Meralco and Maynilad.
Recommended Actions
- Remote Work Advisory
- Allow work-from-home options for employees in flood-affected areas. Monitor PAGASA and MMDA alerts for updates.
