+## Action `openweathermap.get_minute_forecast`
+
+This action populates [response data](/docs/scripts/perform-actions#use-templates-to-handle-response-data)
+with a mapping of minute-by-minute precipitation forecasts (rain or snow) for the next hour.
+
+**Note:** Minute forecast is available only when the OWM integration mode is set to `v3.0`. The action will fail if the mode is set to `current`, `forecast`, or `v2.5`.
+
+```yaml
+action: openweathermap.get_minute_forecast
+target:
+  entity_id:
+    - weather.openweathermap
+response_variable: weather_forecast
+```
+
+The response data field is a mapping of `forecast` fields.
+`forecast` is a list of 60 forecasted precipitation levels; one for each minute of the next hour:
+
+| Response data | Description | Example |
+| ---------------------- | ----------- | -------- |
+| `datetime` | The time of the forecasted conditions. | 2024-10-19T18:59:00+00:00 |
+| `precipitation` | The precipitation amount in mm/h. | 1.25 |
