What this means

Avon Weir is running far below normal at 50.48 m.

That puts it 0.49 m below the median of 50.97 m for mid-October, based on 16 years of readings. A year ago it stood at 50.48 m as well.

The level has held steady over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between 50.46 m and 50.55 m.

Autumn rain usually starts to lift rivers again after the summer low.
