What this means

The River Pang at Tidmarsh is above normal at 1.23 m.

That puts it 0.13 m above the median of 1.10 m for mid-October, based on 21 years of readings. A year ago it stood at 1.10 m (+0.13 m).

It has risen 0.02 m over the past 24 hours. If the rise continues, low-lying paths and riverside parking can go under water. In the last month it has stayed between 1.19 m and 1.26 m.

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