Heavy monsoon rains caused widespread flooding and near-zero visibility across Metro Manila on Thursday night, July 23, 2026 [1].

The extreme weather disrupted one of the region's most critical transport arteries, highlighting the persistent vulnerability of the city's infrastructure to seasonal storms.

Reports indicate that the most severe conditions occurred around nine p.m. [2]. The rainfall led to significant flooding in several parts of the metropolitan area, severely impacting commuters and residents.

Traffic on EDSA, the city's main thoroughfare, reached a standstill. The impact was most acute in the stretch from Cubao to Quezon Avenue, where visibility dropped to near-zero levels [1]. This combination of deep floodwaters and obscured sightlines created hazardous conditions for motorists and public transport operators.

Local authorities monitored the situation as the monsoon-fueled rains swept across the capital. The flooding affected not only the roads but also impacted transit systems, with reports indicating trains were affected by the rising waters.

The event follows a pattern of intense weather systems that frequently challenge the drainage capacity of Metro Manila. While the city has implemented various flood-control measures, the volume of water produced during these monsoon events often exceeds the system's limits, leading to the rapid accumulation of water on major roads [1].

Emergency services remained on alert as the storm passed through the region. The disruption caused significant delays for thousands of workers attempting to return home during the evening rush hour.

“Visibility dropped to near-zero levels on EDSA from Cubao to Quezon Avenue.”

The recurring flooding of EDSA during monsoon events underscores a systemic failure in urban drainage and climate adaptation in Metro Manila. When the primary transit artery of the capital becomes impassable, it creates a ripple effect that halts economic activity and exposes the city's reliance on a fragile infrastructure network that cannot keep pace with increasing rainfall intensity.
