A map showing the distribution of accumulated rainfall, processed from actual rainfall measurements recorded by HII’s automated telemetry weather stations installed nationwide. The spatial distribution is estimated using the Inverse Distance Weight (IDW) interpolation method to calculate and display rainfall patterns in areas surrounding each station. This provides an overview of the actual rainfall amounts across different regions. The data are updated daily, and users can view accumulated rainfall for three time periods: 1 day, 3 days, and 7 days.
