QUEZON CITY, October 24, 2026 — Two powerful weather systems are simultaneously gripping the Philippines this Saturday, confronting millions of Filipinos with rain, wind, and the threat of flash floods and landslides from the country's northernmost islands all the way to the southern tip of Mindanao. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) issued its 4:00 AM forecast warning that Typhoon "Rosal" is bearing down toward northern Luzon while the Intertropical Convergence Zone (ITCZ) saturates large portions of Visayas and Mindanao.
Two Weather Systems, One Country
PAGASA reported that as of 3:00 AM today, Typhoon Rosal — known internationally as Champi — was located approximately 415 kilometers north of Itbayat, Batanes, at coordinates 24.5°N, 122.5°E. The typhoon is carrying maximum sustained winds of 150 km/h near its center, with gusts reaching up to 185 km/h, and is moving southwestward at 10 km/h.
At the same time, the ITCZ is affecting Palawan, Visayas, and Mindanao, extending the country's rain footprint far beyond the typhoon's immediate reach.
What Is Driving This Weather?
Two distinct systems are responsible for today's conditions across the archipelago.
Typhoon Rosal is a tropical cyclone — a large, rotating storm system that draws energy from warm ocean waters and generates destructive winds, heavy rainfall, and dangerous seas. As Rosal moves southwestward, it is directly battering Batanes with its winds and rains, while its outer trough — a trailing band of disturbed weather extending from the typhoon — is funneling clouds and rainfall into portions of northern and northwestern Luzon.
The ITCZ, or Intertropical Convergence Zone, is a broad belt near the equator where trade winds from the northern and southern hemispheres meet, forcing warm, moist air upward. This rising air cools and condenses into persistent cloud cover and rain. Today, it is producing scattered rains and thunderstorms across Palawan, Visayas, and much of Mindanao — entirely independent of the typhoon to the north.
Region-by-Region Forecast
Luzon
Batanes is under the most direct threat today. PAGASA warns of rains with gusty winds caused directly by Typhoon Rosal. The hazards are significant: moderate to at times heavy rains raise the risk of flash floods and landslides, while strong winds pose a minimal to minor threat to life and property. Residents should treat this with full seriousness — "minimal to minor" refers to the structural and life-safety risk from wind alone, not the overall danger from flooding and landslides.
Ilocos Region, Babuyan Islands, Apayao, Abra, and Benguet will experience cloudy skies with scattered rains and thunderstorms, driven by the outer trough of Typhoon Rosal. PAGASA specifically flags the risk of flash floods and landslides due to moderate to at times heavy rains. Mountain provinces and hilly terrain in Benguet, Abra, and Apayao are particularly vulnerable to landslides when rainfall intensifies.
Metro Manila and the rest of Luzon not covered by the above categories can expect partly cloudy to cloudy skies with isolated rain showers or thunderstorms. These are caused by localized thunderstorm activity. While conditions are generally less severe, PAGASA still flags the possibility of flash floods during severe thunderstorm episodes — a reminder that even brief but intense downpours can overwhelm drainage systems.
In terms of winds, the rest of Luzon will experience moderate to strong winds coming from the northwest to southwest, with coastal waters ranging from moderate to rough, with wave heights of 1.5 to 4.0 meters.
Visayas
The entire Visayas region will see cloudy skies with scattered rains and thunderstorms today, driven by the ITCZ. PAGASA warns of possible flash floods and landslides due to moderate to at times heavy rains. This covers all major island groups in the region. Residents in low-lying coastal areas and hilly interiors alike should be on guard.
Wind conditions across Visayas will be light to moderate, coming from the south to southwest. Coastal waters are forecast to be slight to moderate, with wave heights of 0.6 to 2.5 meters.
Mindanao
Portions of Mindanao are also under the ITCZ's influence. PAGASA specifically names Zamboanga Peninsula, Northern Mindanao, Agusan del Norte, Surigao del Norte, Dinagat Islands, Basilan, and Tawi-Tawi as areas that will experience cloudy skies with scattered rains and thunderstorms, with the same flash flood and landslide risks identified for Visayas.
Also included under the same ITCZ-driven weather pattern are Palawan, Masbate, and Sorsogon — areas that straddle the Luzon-Visayas boundary and are similarly affected.
Like Visayas, Mindanao will see light to moderate winds from the south to southwest, with coastal waters ranging from slight to moderate and wave heights of 0.6 to 2.5 meters.
Decoding the Warnings: What Each Hazard Means for You
PAGASA's forecast carries specific hazard flags that every reader should understand before heading out today.
Flash floods can occur with little warning — they develop rapidly when heavy rain overwhelms rivers, streams, and drainage channels. People in flood-prone barangays should be ready to evacuate at a moment's notice and should never attempt to wade or drive through flooded roads.
Landslides are triggered when saturated soil on slopes loses its stability. Communities in mountainous areas of Benguet, Abra, Apayao, and similar terrain in Visayas and Mindanao should stay away from unstable slopes, cliff faces, and riverbanks during and after heavy rains.
Gusty winds in Batanes from Typhoon Rosal can damage lightweight structures, blow away unsecured objects, and make travel — especially by air and sea — extremely dangerous. PAGASA rates the threat to life and property from wind in Batanes as "minimal to minor," but the combined risk from flooding and landslides remains serious.

What It Means for You
Commuters
In Metro Manila and the broader Luzon lowlands, isolated thunderstorms can erupt quickly and intensely. Allow extra travel time, keep an eye on PAGASA's real-time updates before leaving home, and avoid underpasses and low-lying roads that are prone to flash flooding during sudden downpours. In northern Luzon — particularly areas under the typhoon's trough — avoid travel if conditions deteriorate.
Fisherfolk and Small-Boat Operators
Rough to moderate seas across Philippine waters today make conditions hazardous for small vessels. The rest of Luzon's coastal waters are forecast to be moderate to rough, with waves reaching 1.5 to 4.0 meters — conditions that are dangerous for small boats and bancas. Visayas and Mindanao coastal waters are slight to moderate (0.6 to 2.5 meters), which remains challenging for the smallest craft. PAGASA strongly advises fisherfolk to heed sea-state advisories and to delay fishing trips if waves are high.
Farmers
Scattered to at times heavy rains across the Ilocos Region, Visayas, and Mindanao could affect field crops and harvests. Farmers with ripening or recently harvested produce should secure or cover their crops. Flooding of low-lying farmland is a risk in areas under both Rosal's trough and the ITCZ.
Students, Parents, and Schools
Schools in Batanes and the directly affected northern Luzon provinces should coordinate with local government units regarding class suspensions. Even in Metro Manila, isolated severe thunderstorms can prompt local suspension decisions. Parents and students should monitor announcements from their LGUs closely throughout the morning.
Outdoor Workers
Construction workers, delivery riders, and others who work outdoors — especially in Batanes and the provinces under the trough of Typhoon Rosal — face elevated risk today from gusty winds and rain. Employers in affected areas should consider whether outdoor operations can be safely postponed or modified. Workers in Visayas and Mindanao should also be prepared for intermittent heavy downpours throughout the day.
Temperature Outlook
PAGASA's weather station at Science Garden in Diliman, Quezon City, recorded a maximum temperature of 31.7°C at 3:00 PM and a minimum of 26.9°C at 6:00 AM for the 24-hour period ending at 8:00 PM on October 23, 2026. Relative humidity peaked at 81% at 6:00 AM and dipped to a minimum of 52% at 2:00 PM. Widespread cloud cover and rain across much of the country today may moderate daytime temperatures in many areas.
Tides and Astronomical Information for Metro Manila
For Manila Bay today, October 24, PAGASA and NAMRIA report the following tide schedule: low tide at 2:16 AM (0.31 m), high tide at 8:38 AM (0.76 m), low tide at 2:57 PM (0.22 m), and high tide at 9:10 PM (0.74 m). Sunrise is at 5:49 AM and sunset at 5:31 PM. The moon rises at 4:00 PM and sets at 3:45 AM, with a 97% illumination — nearly a full moon. Coastal communities should take note of high tide times in relation to any storm surge or localized flooding risks.
Bottom Line
Today's single most important action: If you live in Batanes, Ilocos Region, Babuyan Islands, Apayao, Abra, or Benguet — or in any flood-prone or landslide-prone community across Visayas and Mindanao — identify your evacuation route and be ready to move quickly if local authorities issue an evacuation order. Do not wait for floodwaters or a landslide to force you out. Everyone else should avoid flood-prone areas during thunderstorms and stay updated throughout the day.
