The Philippines woke up to widespread rainfall and unsettled skies on Saturday, July 11, 2026, as two powerful weather systems work in tandem to drench much of the archipelago. Typhoon Inday, known internationally as Bavi, is churning well northeast of the country, while the southwest monsoon — the seasonal "habagat" — continues to push moisture-laden air over Luzon, Visayas, and Mindanao. The combination, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), is generating conditions that range from life-threatening storminess in the far north to scattered downpours across the south.
Two Systems, One Wet Saturday
PAGASA's 4:00 AM weather bulletin identified the two drivers behind today's widespread wet weather. The first is Typhoon Inday (Bavi), whose center was placed approximately 1,490 kilometers northeast of Itbayat, Batanes as of 3:00 AM. Moving northwestward at 20 km/h, the typhoon is packing maximum sustained winds of 140 km/h near its center and destructive gusts of up to 170 km/h. Although the typhoon's core remains a great distance from the Philippine landmass, its outer rain bands are already hammering the northernmost province of Batanes and are amplifying rainfall across Cagayan Valley.
The second system is the southwest monsoon, a seasonal weather pattern that draws warm, wet air from the sea across the western flanks of the Philippine island chain. PAGASA reported that the habagat is currently affecting Central and Southern Luzon, the Visayas, and Mindanao — meaning that even regions far removed from the typhoon are dealing with significant rainfall driven entirely by the monsoon.
By the Numbers
- Typhoon Inday's center: approximately 1,490 km northeast of Itbayat, Batanes (as of 3:00 AM)
- Maximum sustained winds near the typhoon's center: 140 km/h
- Peak wind gusts: up to 170 km/h
- Typhoon's movement speed: 20 km/h northwestward
- Coastal wave heights along western Luzon, Visayas, and Mindanao: 1.5 to 3.1 meters
How Each Region Is Affected
Northern Luzon
Batanes is facing the most severe conditions in the country today. PAGASA's bulletin describes stormy conditions there — a designation that signals dangerous winds, heavy rain, serious disruption to transportation, and threats to both life and property. Residents in Batanes are strongly advised to remain indoors, stay away from windows, and avoid flood-prone zones.
Neighboring Cagayan is also feeling Typhoon Inday's reach, with rains and gusty winds forecast throughout the day. While the threat level is classified as minimal to minor compared with Batanes, PAGASA cautioned that flash floods and landslides remain possible — particularly near rivers, creeks, and hilly terrain. Residents should secure loose items around their homes and think twice before making unnecessary trips.
The rest of the Cordillera Administrative Region (CAR), Ilocos Norte, Ilocos Sur, and Mountain Province fall under the combined pull of both the typhoon and the southwest monsoon. These areas can expect cloudy skies with scattered to moderate rains, along with possible flash floods, landslides, and threats from strong winds.
Metro Manila and Central Luzon
Metro Manila, MIMAROPA, La Union, Pangasinan, Benguet, Zambales, Bataan, Cavite, and Batangas are all under the southwest monsoon's influence, according to PAGASA. Occasional rains are forecast throughout the day. Low-lying communities and those near mountain slopes should stay alert to the possibility of flash floods and landslides if rainfall intensifies.
The remaining areas of Luzon not specifically listed in the bulletin are expected to experience cloudy skies with scattered rainshowers or thunderstorms driven by the habagat, with the same flash flood and landslide cautions applying.
Visayas
Western Visayas and the Negros Island Region — including Negros Oriental — are under the southwest monsoon's coverage and can expect occasional rains, with flash flood and landslide risks in areas of moderate to heavy downpours. Eastern Visayas and Central Visayas, along with the rest of the region, are forecast to have cloudy skies and scattered rainshowers or thunderstorms, also attributed to the habagat. PAGASA reminded residents throughout the Visayas to remain cautious, as moderate to heavy rains can rapidly raise water levels in low-lying and riverside communities.
Mindanao
The Zamboanga Peninsula, BARMM (Bangsamoro Autonomous Region in Muslim Mindanao), and SOCCSKSARGEN are forecast to see cloudy skies with scattered rainshowers or thunderstorms under the influence of the southwest monsoon. Flash floods and landslides are flagged as possible hazards. The rest of Mindanao can expect partly cloudy to cloudy skies with isolated rainshowers or thunderstorms. PAGASA warned that severe localized thunderstorms could still produce sudden, intense downpours capable of triggering flash floods even in areas where overall conditions appear less threatening.
Sea Conditions: Small Vessels Warned to Stay Ashore
Coastal communities and fishing households across the country should take note of dangerous maritime conditions, PAGASA warned. Along Western Luzon, moderate to strong winds are driving rough seas with wave heights of 1.5 to 3.1 meters. The same wave height range applies to all coastal sides of the Visayas and Mindanao, where moderate to strong southwest winds are generating moderate to rough sea conditions. Waves reaching 3.1 meters are considered life-threatening for small fishing boats and bancas. PAGASA strongly advised all small vessel operators to remain ashore until conditions improve, and urged residents in coastal areas to monitor the latest maritime advisories.
Understanding the Hazard Warnings
PAGASA's use of the term "stormy conditions" for Batanes represents the most severe forecast language in today's bulletin — indicating wind speeds and rainfall that can damage structures, render roads impassable, and place lives at risk. For Cagayan, "rains with gusty winds" warns that wind-driven damage to trees, power lines, and lightweight structures is plausible even without the extreme conditions seen further north.
The agency's near-universal flash flood and landslide flags across all regions serve as a reminder that even moderate rainfall over mountains and upstream watersheds can rapidly push dangerous volumes of water into lowland communities. People living near waterways, drainage channels, or unstable hillsides should have an evacuation plan ready and act on it immediately if water levels begin to rise — without waiting for an official order.
For commuters in affected areas, PAGASA's forecast points to a wet morning and afternoon across Metro Manila, CAR, the Ilocos Region, Cagayan Valley, and throughout the Visayas and Mindanao. Rain gear is essential, and motorists should watch for flooded roads, reduced visibility, and hazardous driving conditions on low-lying routes.
Why This Matters
The simultaneous activity of Typhoon Inday (Bavi) and the southwest monsoon means that virtually no region of the Philippines is entirely free of weather-related hazards today, stretching the capacity of disaster-response agencies and local government units from Batanes all the way to southern Mindanao. The wave heights of up to 3.1 meters reported by PAGASA pose a direct threat to the livelihoods and lives of small-scale fishermen who depend on daily sea access. With flash flood and landslide risks flagged across almost all regions, communities in low-lying areas and near mountainous terrain face an elevated danger that demands vigilance and readiness to evacuate on short notice.
