Experimental estimate. There is no river gauge in Teldeniya; this uses Peradeniya, 19 km away, plus rain at the town and official warnings.

Details

How this estimate works

· Starts from the river gauge's own level and forecast, the same as the gauge page.
· Heavy rain here (50 mm in 6 hours or 100 mm in 24 hours) raises it by one step, never more.
· Your own street level, if you set one, and official warnings can raise it further.
· It never says flooding is happening: only a measurement can show that.
