Typhoon Pepito, also known internationally as Man-yi, has exited the Philippines after causing heavy rainfall, gusty winds, and widespread disruption. As it leaves Luzon and continues to move westward towards southern China, the storm is weakening but remains a significant weather system. Below is a detailed breakdown of its impact, current status, and what to expect moving forward.
Current Situation
As of Monday morning, Typhoon Pepito’s low-level center was positioned west of Luzon, near the coast of Ilocos Sur. It exited the Philippines after passing through northern and central Luzon, including areas such as Cagayan, Baguio, and Pangasinan. The mountainous terrain of Luzon significantly weakened the system, but it still maintains typhoon intensity as it tracks towards the South China Sea.
Satellite Imagery and Structure
Satellite imagery reveals:
- A defined low-level center, with residual banding bringing rain and gusty conditions to parts of northwestern Luzon.
- Heavy rainfall concentrated on the storm’s trailing edge, affecting provinces like Pangasinan, Zambales, and portions of northern Luzon.
- Persistent inflow of moisture contributing to downpours in other areas, particularly along the west coast.
Impact on the Philippines
Rainfall and Flooding
- Central Luzon: The storm dumped large amounts of rainfall in provinces like Aurora, Pangasinan, and Tarlac, triggering localized flooding and rising river levels.
- Cagayan Valley: Sustained rainfall led to concerns about delayed flooding as upstream water from mountain regions flows downstream over the next 24–48 hours.
- Metro Manila: While not directly in the typhoon’s path, the metro area experienced intermittent showers and rising water levels in connected waterways.
Wind and Coastal Conditions
Typhoon Pepito brought gusty winds that toppled trees and damaged infrastructure, especially in areas closer to its landfall point. Coastal communities along the west experienced rough seas, with waves reaching 1 to 3 meters in height.
Path and Forecast
Track and Strength
- After making its initial landfall in Casiguran, Aurora, the typhoon crossed Luzon, exiting near La Union.
- Forecasts indicate it will weaken as it tracks south of Hong Kong and towards Hainan, China, due to interaction with the northeast monsoon and cooler air masses.
Weather Outlook for the Philippines
- Monday: Lingering rain bands will continue affecting parts of northwestern Luzon. By the afternoon, drier conditions are expected across most regions.
- Tuesday–Wednesday: Northerly winds will bring cooler and drier air, marking a shift to typical monsoon weather.
Preparing for Post-Storm Effects
Flooding Risks
Residents in low-lying and flood-prone areas are advised to remain vigilant. While rainfall has subsided in most areas, delayed flooding is likely as water from mountainous regions flows downstream into major river systems.
Coastal Hazards
Seafarers and coastal residents should avoid the waters along the western coastline of Luzon due to strong waves and swells.
International Concerns
Southern China and Hong Kong
- Typhoon Pepito is forecasted to bring moderate rainfall and gusty winds to parts of southern China, particularly Hong Kong and Hainan, by mid-week.
- While the system is expected to weaken, localized heavy rainfall and potential warnings from local authorities should be closely monitored.
Key Statistics
- Landfall pressure: 935 hPa (hectopascals) at peak intensity.
- Post-Luzon pressure: 955 hPa, indicating weakening after crossing land.
- Wave heights: 1–3 meters along the Philippine coasts, increasing further west.
Frequently Asked Questions (FAQ)
1. Where did Typhoon Pepito make landfall?
Typhoon Pepito made landfall in Casiguran, Aurora, before crossing central Luzon and exiting near La Union.
2. What were the strongest impacts on Luzon?
The typhoon brought heavy rainfall, causing flooding and rising river levels. Gusty winds damaged infrastructure and disrupted power in some areas. Coastal communities also faced rough seas and high waves.
3. How has the storm weakened after hitting Luzon?
The mountainous terrain of central and northern Luzon disrupted the storm’s structure, causing its pressure to rise and wind speeds to decrease. It remains a typhoon but is gradually weakening as it moves into the South China Sea.
4. What is the expected impact on southern China?
Southern China, including Hong Kong and Hainan, will experience moderate rainfall and breezy conditions. Pepito is not expected to retain significant strength but could still trigger localized flooding.
5. What precautions should residents in affected areas take?
- Stay alert for flood warnings in low-lying areas.
- Avoid traveling through flooded roads or crossing rivers.
- Follow updates from local authorities for weather advisories.
6. Is there another storm forming after Pepito?
As of now, weather models indicate no significant storm systems in the immediate forecast for the Philippines. However, changes in weather patterns should be monitored, especially during the typhoon season.
Final Thoughts
Typhoon Pepito / Man-yi demonstrated the dual threats of wind damage and heavy rainfall, particularly in mountainous and flood-prone regions. While the immediate impacts are waning, post-storm hazards like flooding and rising water levels remain critical concerns.
For residents in Luzon and beyond, the shift to cooler northerly winds signals a return to calmer weather in the days ahead. However, those in Pepito’s projected path—especially in southern China—should prepare for moderate impacts.
Stay safe, stay informed, and continue monitoring updates from official weather agencies.
