QUEZON CITY, October 23, 2026 — Typhoon Rosal is bearing down on the northern Philippines this Friday, threatening Batanes with stormy weather, powerful winds, and life-threatening flash floods and landslides, while spreading heavy rains and rough seas across a wide stretch of Luzon and the Visayas. PAGASA issued this forecast at 4:00 AM today, valid until 4:00 AM on October 24.
What Is Driving This Weather
At 3:00 AM on October 23, the center of Typhoon Rosal — known internationally as Champi — was located approximately 280 km east-northeast of Itbayat, Batanes, at coordinates 22.0°N, 124.2°E. The typhoon is packing maximum sustained winds of 155 km/h near its center, with gusts reaching up to 190 km/h, and is moving northwestward at 15 km/h.
A typhoon is the strongest category of tropical cyclone in the Philippine classification system — a large, organized storm system that draws energy from warm ocean water, spinning winds inward and upward with tremendous force. As Rosal moves toward the north, its outer rain bands are already drenching a wide area of Luzon, while its trough — a low-pressure extension trailing behind the main storm — is pulling moisture and cloudiness as far south as Mindanao.
Region-by-Region Forecast
Luzon
Batanes faces the most severe conditions today. PAGASA describes the weather there as stormy, caused directly by Typhoon Rosal. Intense rains are expected, and the agency warns of possible flash floods and landslides. There is a minor to moderate threat to life and property from strong winds. Residents of Batanes should take this forecast with the highest seriousness and follow all instructions from local disaster risk reduction authorities.
Ilocos Norte, Apayao, Cagayan, and Isabela are experiencing rains with gusty winds, also driven by Typhoon Rosal. PAGASA warns of possible flash floods or landslides due to moderate to heavy rains, with a minimal to minor threat to life and property from strong winds. People in low-lying and mountainous areas of these provinces should remain alert.
The rest of the Cordillera Administrative Region (CAR), the remaining portions of Cagayan Valley, Ilocos Sur, La Union, and Aurora can expect cloudy skies with scattered rains and thunderstorms, also attributable to Typhoon Rosal. PAGASA warns these areas of possible flash floods or landslides due to moderate to at times heavy rains. Mountain communities in CAR are particularly vulnerable to landslides when sustained rainfall soaks steep terrain.
Metro Manila and the rest of the country not specifically listed will see partly cloudy to cloudy skies with isolated rainshowers or thunderstorms. These are caused by localized thunderstorm activity. Flash floods remain possible during severe thunderstorms even in areas outside the typhoon's direct path, so residents in flood-prone urban areas should remain cautious.
Visayas
The Visayas as a whole — along with Masbate and Palawan — are under cloudy skies with scattered rains and thunderstorms. PAGASA attributes these conditions to the trough of Typhoon Rosal, meaning the storm's trailing low-pressure zone is drawing rain-producing clouds into the region even though the typhoon's center is far to the north. Flash floods and landslides are possible due to moderate to at times heavy rains. The eastern section of the Visayas faces additionally rough coastal waters.
Mindanao
Zamboanga Peninsula, Lanao del Norte, Misamis Occidental, Basilan, and Tawi-Tawi are included in the areas affected by the trough of Typhoon Rosal, with cloudy skies, scattered rains, and thunderstorms forecast. Flash floods and landslides are possible from moderate to at times heavy rains. The remainder of Mindanao and the rest of the Visayas will experience light to moderate winds from the south to southwest, with coastal waters described as slight to moderate, with wave heights of 0.6 to 2.5 meters.
Decoding the Warnings
PAGASA's forecast for Batanes carries its most direct warning language: "stormy" conditions with a "minor to moderate threat to life and property." This reflects the immediate danger posed by a typhoon at close range — not merely inconvenient rain, but wind-driven hazards and rainfall intense enough to trigger flash flooding and landslides within hours.
The warnings for flash floods and landslides in Ilocos Norte, Apayao, Cagayan, Isabela, CAR, Ilocos Sur, La Union, Aurora, the Visayas, and parts of Mindanao reflect the risk of moderate to heavy rainfall overwhelming drainage systems or saturating hillside soil to the point of collapse. Even areas not in the typhoon's direct path face genuine danger when prolonged heavy rain is in the forecast.

Wind and Coastal Water Conditions
PAGASA has identified two distinct wind and sea-state zones across the country today.
Central Luzon, Southern Luzon, and the eastern section of the Visayas will experience moderate to strong winds blowing from the northwest to southwest. Coastal waters in these areas are described as moderate to rough, with wave heights of 2.5 to 4.0 meters. These are dangerous conditions for small watercraft.
Mindanao and the rest of the Visayas will have light to moderate winds from the south to southwest. Coastal waters there are slight to moderate, with wave heights of 0.6 to 2.5 meters. While less severe, even these conditions require caution from small boat operators.
What It Means for You
Commuters
In Metro Manila and other major urban centers outside the typhoon's immediate path, expect isolated rainshowers and thunderstorms that can strike quickly and intensely. Flash floods in low-lying streets are possible during severe thunderstorm episodes. Allow extra travel time, monitor local traffic and weather updates, and avoid crossing flooded roads. In affected provinces in northern Luzon, road travel may be significantly disrupted by strong winds and heavy rain. Check with local authorities before traveling through Batanes, Ilocos Norte, Cagayan, Isabela, Apayao, and CAR.
Fisherfolk and Small Boat Operators
PAGASA's forecast is clear: coastal waters off Central Luzon, Southern Luzon, and the eastern Visayas are moderate to rough, with waves reaching up to 4.0 meters. Small boats and fishing vessels should not venture into these waters today. Even in Mindanao and the rest of the Visayas, where seas are slight to moderate, conditions can change rapidly as Rosal continues moving. Fisherfolk who are already at sea in affected areas are strongly urged to return to port and seek shelter.
Farmers
Heavy to intense rains across northern and central Luzon, and scattered to moderate rains across the Visayas and parts of Mindanao, pose risks to standing crops and low-lying farmland. Flash flooding and potential landslides in upland areas of CAR, Cagayan Valley, Ilocos Norte, and Apayao may damage farm plots and access roads. Secure equipment and harvested produce where possible.
Students, Parents, and School Officials
Families in Batanes, the Ilocos region, Cagayan Valley, Aurora, and the Cordillera should watch for class suspension announcements from local government units, as stormy to heavy rain conditions make travel dangerous. In the Visayas and the affected parts of Mindanao, rain and thunderstorms may also prompt local officials to act. Parents should monitor announcements from their LGUs and school divisions closely throughout the morning.
Outdoor Workers
Construction workers, delivery personnel, and others working outdoors in Batanes and the surrounding northern Luzon provinces face the most immediate risk today — strong gusts of up to 190 km/h near the typhoon's center make outdoor work life-threatening in Batanes. Even in provinces receiving Rosal's outer rainbands, gusty winds and heavy downpours pose real hazards. Supervisors and employers in affected areas should assess whether outdoor work can safely proceed today.
Temperature Outlook
For reference, PAGASA recorded the following temperature extremes at its weather station in Science Garden, Diliman, Quezon City, for the 24-hour period ending at 8:00 PM yesterday, October 22:

Bottom line: Typhoon Rosal is the dominant weather story across the Philippines today, October 23, 2026. If you are in Batanes or the typhoon-affected provinces of northern Luzon — including Ilocos Norte, Cagayan, Isabela, Apayao, and the Cordillera — stay indoors, stay away from coastal and riverside areas, and follow all advisories from your local government. Small boat operators across Central Luzon, Southern Luzon, and the eastern Visayas should remain in port. The single most important thing you can do today: do not travel through or venture into high-risk areas unless it is absolutely necessary and you have confirmed it is safe.
