There is a single alert at the start of each weather event. It is then up to you to monitor this site.
Floodwatch is a free flood monitoring service created by Steve Davis
If you don't cross any of the creeks available to monitor, this service isn't really something you need. If you do cross the creeks, this is why you need it: Springbrook Rd at Austinville Rd March 22nd 2021
To subscribe, choose the location, then subscribe on that page.
Other creeks can be included (and the system is set up for them), they may be able to be added on request.
