Heavy Rain Forecast to Bring Relief but Not Reverse UK Drought

The UK is bracing for heavy rain this week, which may bring some relief to parched land and firefighters tackling wildfires. However, the forecast rain will not be enough to reverse the widespread drought conditions that have been affecting the country.

The Met Office has predicted that the rain will fall on hard, dry ground, which may cause surface water flooding in some areas. Deputy chief forecaster Mike Silverstone warned that showers would be heavy in some parts of the country, particularly in the north-west, and that some areas would miss them altogether.

The rain may bring some welcome relief to areas most in need, but water shortages will persist. South East Water has told customers in Kent to use water only for "essential" purposes, after taps ran dry on Monday for around 8,000 customers. Wessex Water has also imposed a hosepipe ban, covering 1.4m customers in Bath, Somerset, Dorset, and Wiltshire.

The drought has put pressure on wildlife, farmers, firefighters, and water resources. The Environment Agency has warned that five of England's key reservoirs are currently "exceptionally low", and the National Hydrological Monitoring Programme has warned that low supplies are likely to persist into the autumn.

Thames Water has also urged customers to continue to limit water use. The company said that since it imposed its hosepipe ban on 23 July, household demand had fallen by 3% across London and more than 6% across the Thames Valley and home counties.

The drought has been exacerbated by the summer's fifth climate crisis-driven heatwave, which has been followed by wetter and cooler weather that is much closer to the usual conditions for the time of the year.

Liz Stephens, a professor in climate risk and resilience at the University of Reading, warned that it could take many weeks of sustained rainfall for vegetation to recover and rivers and reservoirs to return to normal. "Here in the south-east, we're still a month's worth of rain below what we would normally expect by this point in the year, despite the heavy rainfall in January and February," she said.

### Water Shortages Persist

The drought has put pressure on water resources, with many water companies imposing hosepipe bans. South East Water was the first water company to issue a hosepipe ban this summer, on 3 July for customers in some parts of Kent. On Tuesday, Wessex Water became the latest, with its first ban since the summer of 1976.

The company blamed increased demand during the dry weather, but also longer-term weather forecasts that mean resources must be protected for customers and the environment.

### Reservoir Levels Remain Low

Reservoir levels remain low, with five of England's key reservoirs currently "exceptionally low". The National Hydrological Monitoring Programme has warned that low supplies are likely to persist into the autumn.

London reservoir storage is at 74% as a result, far lower than expected for this time of year. Thames Water's director of water, Martin Padley, said: "With reservoir levels below where we would expect them to be for this time of year and demand remaining high, we're asking customers to keep going and continue using only what they need.

### Floods Can Still Occur During Drought Conditions

Floods can still occur during drought conditions, and surface water flooding can even become more likely as baked soils are unable to soak up rainwater as quickly. Liz Stephens warned that it could take many weeks of sustained rainfall for vegetation to recover and rivers and reservoirs to return to normal.

The situation is "simply not good enough", according to a spokesperson from the Department for Environment, Food and Rural Affairs. "South East Water needs to go further and faster to reduce leaks and follow their drought plans to ensure supplies are not disrupted in even the driest of weather," the spokesperson said.
