AI analysis
18 Oct, 19:00• Analysis: There has been hardly any rain over the past two days, so there's little water feeding in from the hills and surrounding land.
• Trend: The river is falling steadily, having dropped a noticeable amount over the last 24 hours.
• Forecast: Some rain is expected over the next few days, but it looks modest, so expect only a slight lift rather than any significant rise.
Written automatically by an AI model from the readings and forecast. It can get things wrong, and it is not a flood warning.

How to read this
This is experimental. We check every prediction against what the river actually did, and we'll keep improving it as more results come in.
This works out, day by day, where the river could get to if the forecast rain falls. Each day carries on from where the day before is likely to have left it, so rain on several days in a row builds up.
For each day's rain we looked back at past days when about the same amount fell, at any time of day, and how much the river rose. The dot adds the typical rise to where the river is expected to start that day. Between days, the river falls back by about as much as it has before: by the start of the next day, roughly two thirds of a rise is typically still there. Rain still to come counts for today; rain that has already fallen is in today's level.
The blue band is the likely range: on half of those past days the river ended up inside it, on a quarter lower and on a quarter higher. It widens the further ahead it looks. Hover over or tap a bar for the figures.
It only looks 3 days ahead, because beyond that the rain forecast itself gets unreliable. It only uses past days when the sensor reported often enough to catch the peak. Heavy downpours, wet ground, or rain on several days running can take the river higher. A rough guide from past records, not a flood forecast.
