Notice:
On August 8th, this app was featured on television as a valuable tool for countering sudden torrential rainfall.

It is important to note that high-precision forecasts are only available for up to 30 minutes in advance; thus, we recommend setting notification timings within 30 minutes of expected rainfall for optimal accuracy.
