Verified facts

What happened

PAGASA said the southwest monsoon, or Habagat, was expected to weaken, according to the August 11 weather report cited in the FMB News bulletin.

The expected weakening does not mean rain hazards have ended. Areas that have already received repeated rainfall can remain vulnerable to flooding, rising waterways and rain-induced landslides even as the broader monsoon pattern changes.

Context

Context

Habagat commonly brings moist southwesterly winds and periods of rain to western sections of the Philippines. Local impacts vary with the position and strength of the monsoon flow, terrain, previous rainfall and drainage conditions.

FMB News is using the cautious formulation “expected to weaken” rather than describing the weakening as already complete.

Filipino relevance

Why this matters to Filipinos

Flood and landslide risk can persist after heavy rain because rivers, reservoirs and soil conditions respond over time. Residents in repeatedly affected communities still need current location-specific advisories even when the wider weather system is forecast to ease.

What to watch next

What to watch next

Continue checking PAGASA rainfall and weather bulletins and local disaster-office advisories. The important next signals are changes in rainfall warnings, river or dam levels, and any evacuation instructions for flood- or landslide-prone communities.
