Rain that fell: No recent reading from this gauge's rain sensor.
Rain forecast: Not available right now.

· Trend only: this gauge has no published flood levels or catchment rain grid, so no model was fitted.
· Topmost gauge on its river: no gauge upstream, so only its own trend (plus catchment rain) is available.
· No rain data reported nearby; rain effects not factored in.

How this is worked out
· 'Level stays the same' with a range taken from how much this gauge has really changed in an hour. In a backtest no model beat 'no change' here (one hour ahead only). This is the topmost gauge on its river, so there is no upstream gauge; the catchment rain above is the only upstream signal.
