PAGASA Regional Services Website

PAGASA has five (5) regional services divisions in Northern Luzon, National Capital Region, Southern Luzon, Visayas, and Mindanao provide localized forecasts in their respective forecast areas. One way to disseminate this localized weather forecast is by using a tailor-fit website.

The new version offers a harmonized user experience in accessing the provincial-level forecast for the next 5 days. Thunderstorm Advisories, Heavy Rainfall Warnings, and Special Weather Forecast, allowing users to navigate through the five (5) websites seamlessly.

Moreover, the provincial-level weather forecast on the first day was divided into day and night forecasts. This information provides a more detailed weather forecast scenario and gives the public better planning and decision-making in their day-to-day activities.

PANaHON Platform
The PAGASA Nationwide Met-Hydro Observing Network, commonly known as PANAHON, represents a significant leap forward in the Philippines' meteorological and hydrological capabilities since it enables the public to access real-time data from various observational tools such as synoptic stations, Automatic Weather Stations (AWS), meteorological satellite, radar, and lightning detection systems in one map. PANaHON Decision Support Information Tool provides a timely understanding of weather conditions across the country by consolidating the data on a single interactive map. This not only enhances weather forecasting accuracy but also improves disaster preparedness and response, which is critical in a country frequently affected by typhoons and other severe weather events.
A standout feature of PANaHON is its user-friendly online platform allowing the public to visualize the real-time weather data from synoptic stations, which offer insights into atmospheric pressure, temperature, heat index, wind speed, and humidity. In addition to weather data, available weather satellites and radar images can aid users in tracking weather systems such as tropical cyclones, thunderstorms, etc. Also, lightning occurrence data is available on the PANaHON platform.
PANaHON can help disaster responders in planning and decision-making strategies. The combination of professional tools and public accessibility highlights PANaHON’s importance as a key instrument for improving weather monitoring, forecasting, and disaster management in the Philippines.
