    Experimental estimate. There is no river gauge in Thanamalwila; this uses Thanamalwila, 3.3 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.

    Why

    • Kirindi Oya is well below flood levels and no heavy rain is expected
