Analysis Notes

Rainfall is calculated from the change in cumulative rainfall recorded by the WeatherFlow station.

Calculations use the actual timestamps of the observations rather than assuming a fixed five-minute interval.

Data note: Results are calculated from stored station observations and the configured IDF reference curves. Use official records and applicable engineering standards for design, regulatory or emergency decisions.
