How this guidance is produced

Hourly model guidance is retrieved for selected city coordinates. Rainfall is summarized as the maximum rolling 24-hour accumulation within the chosen horizon; thunderstorm-coded hours use WMO weather codes 95–99; wind uses the maximum modeled 10-m gust. Thresholds below are editorial screening cues, not calibrated impact-based alerts.

Screening cues: ≥50 mm of modeled rain in a rolling 24 hours; ≥50 km/h peak wind gust; any thunderstorm-coded forecast hours. These values are not official national warning thresholds, and may miss local severe convection.

Data: Open-Meteo model aggregation, local time Asia/Jakarta (WIB), non-commercial evaluation. Forecast may combine different underlying numerical models; do not attribute the result exclusively to ECMWF or GFS. Model values are not observations. No rainfall or risk field is interpolated between cities.
