From 19 June 2025, SES Tasmania will provide an updated rainfall and river alerting service through the TasALERT mobile app.
The Rainfall and River Alert system provides alerts of
- heavy rain and
- river rises
in selected rural locations.
The Alerts help farmers and others decide if they need to act. For example, they may move livestock and farming equipment from flood prone land.
TasALERT website and app is the home of emergency information and warnings for Tasmanians.
Users now have more control over the Alerts they receive. They can receive Alerts as emails and push notifications on their mobile device.

Why are these changes happening?
Technology improvements are changing the way the Alerts are delivered. Over time the alerts have been telegrams, faxes, emails, and SMS.
For the last 20 years the Bureau of Meteorology has provided the service for the SES.
Recent upgrades to
- the Bureau’s forecasting system, and
- the Tasmanian Government’s TasAlert app
means SES and the Bureau can also upgrade this service.
For any questions on the SES Rainfall and River Alert service email ses@ses.tas.gov.au or call 6173 2700.
