UK Flood Risk High Today and Through the Coming Days – 17 Dec 2025

A Period of Sustained Flood Pressure Is Now Underway

Flood alerts and warnings are active across large parts of England today, with river levels already high and ground conditions saturated. While some rivers have peaked and begun to fall, many remain at elevated levels, and further rainfall forecast for Wednesday and Thursday means the risk of flooding remains significant and ongoing.

This is not a short, sharp event. It is a multi-day flood risk window.

Why Flood Risk Remains High

Several factors are combining to keep flood risk elevated:

• Catchments are fully saturated, limiting absorption
• Rivers are slow to fall after earlier rainfall
• Further rain is forecast, particularly mid-week
• In some areas, groundwater levels are rising, which can cause prolonged flooding
• Low-lying drainage systems and pumping stations are already under pressure

Even moderate additional rainfall may be enough to trigger renewed river rises.

Areas Most Affected

Flood alerts and warnings currently cover:

• South West England (Devon, Somerset, Dorset)
  Multiple river systems remain high, with flooding affecting roads, farmland, and low-lying communities. Groundwater flooding is also a concern in parts of Dorset.
• The Midlands (Warwickshire, Leicestershire, parts of the Severn and Avon catchments)
  Rising rivers are affecting low-lying roads, footpaths, farmland, and some caravan parks.
• Eastern England drainage systems
  Minor watercourses and artificial drainage networks are under strain, with a risk of escalation if rainfall continues.

These situations are being actively monitored, and conditions may change quickly if rainfall intensity increases.

What to Expect Over the Next Few Days

• Rivers may fall slowly, then rise again
• Flood alerts are likely to remain in place or expand
• Flood warnings may be issued at short notice
• Road flooding is the most likely and immediate impact
• Groundwater flooding may persist even after rain stops

Thursday is a key risk day in several catchments.

Practical Advice

• Avoid walking, cycling, or driving through floodwater
• Do not rely on familiar routes remaining open
• Monitor local river levels and official updates
• Prepare for delays, diversions, and temporary access issues
• If you live in a flood-prone area, ensure property protection measures are ready

Final Note

This flooding risk is widespread, slow-moving, and persistent — not sudden or dramatic, but disruptive and potentially long-lasting.

A follow-up post will look at how this type of multi-day flooding typically develops, what to watch for locally, and how to make practical short-term preparations.

Stay aware, stay cautious, and plan for disruption rather than danger.
