Red Alert: Iloilo Braces for Worst as Habagat Unleashes Torrential Rains

Residents across Iloilo province are on high alert after state weather authorities raised red and orange rainfall warnings on Friday, July 24, as the southwest monsoon—locally known as habagat—intensified dramatically.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) issued the highest-level red warning for several areas, signaling severe flooding and potential landslides. The orange warning, one notch below, covers additional municipalities, urging immediate evacuation in vulnerable zones.

What the Warnings Mean

The color-coded alert system is critical for public safety:

• Red Warning: Indicates serious flooding in low-lying areas. Residents must evacuate to higher ground immediately. Rainfall exceeds 30 millimeters per hour and is expected to persist.
• Orange Warning: Signifies flooding is threatening. Communities should prepare for possible evacuation as rainfall ranges from 15 to 30 mm per hour.

As of Friday morning, PAGASA reported that Iloilo City and nearby towns had already recorded over 100 mm of rainfall in the past 24 hours—equivalent to more than a month’s average for July.

Emergency Response Activated

The Iloilo Provincial Disaster Risk Reduction and Management Office (PDRRMO) has raised its emergency operations center to full alert status. “We are monitoring river levels, especially the Jalaur and Tigum rivers, which are already near critical points,” said PDRRMO chief Jerry Bionat in a statement.

Local government units have deployed rescue teams, prepositioned food packs, and opened evacuation centers in schools and barangay halls. The Philippine Coast Guard has suspended sea travel in affected areas, stranding hundreds of passengers at Iloilo ports.

Communities on Edge

In the coastal barangay of Villa Arevalo, residents began moving their belongings to upper floors before noon. “We’ve seen this before. When the red warning comes, we don’t wait,” said 54-year-old fisherman Rodrigo Santos, carrying a sack of rice to a neighbor’s two-story house.

The Iloilo City government has activated its flood control pumps, but many streets in downtown areas were already impassable by midday. Social media posts showed waist-deep water along General Luna Street and near the Iloilo River Esplanade.

Background: Why the Habagat Is So Severe

The enhanced southwest monsoon is being driven by a combination of factors:

• A low-pressure area east of Luzon is pulling moist air from the Indian Ocean and South China Sea.
• Warmer sea surface temperatures in the Pacific are fueling stronger convection.
• Climate change is increasing the intensity of seasonal rains, according to recent studies by the Manila Observatory.

Iloilo, situated on the southern coast of Panay Island, is particularly vulnerable. Its flat terrain and numerous rivers make it prone to flash floods during prolonged monsoon rains.

Implications for the Region

The economic impact is already mounting. Iloilo City, a major economic hub in the Visayas, relies heavily on trade and agriculture. Rice fields in nearby towns like Oton and San Miguel are submerged, threatening the upcoming harvest. The Iloilo Economic Development Council estimates that a week of severe flooding could cost the local economy over PHP 200 million in lost productivity.

Tourism, a growing sector, is also affected. Ferries to Guimaras Island and Boracay have been suspended, and several hotels in Iloilo City have reported cancellations.

What’s Next?

PAGASA forecasts that the habagat will persist through the weekend, with possible improvement by Monday. However, meteorologists warn that another weather disturbance could develop in the coming days.

“We urge everyone to remain vigilant,” said PAGASA weather specialist Ana Liza Solis. “Even after the rain stops, river levels will remain high for at least 48 hours.”

For now, Iloilo’s 2.5 million residents are bracing for what could be one of the worst monsoon episodes in recent memory. As the red warning blazes across weather apps and radio broadcasts, the message is clear: prepare for the worst, hope for the best.
