The Met Office has sounded a warning bell for southern England, where heavy rain is set to bring potentially hazardous conditions from 6am on Saturday, May 18th. A yellow warning, which will remain in force until 6pm the same day, highlights risks of localised flooding and challenging driving conditions, particularly in urban areas and low-lying regions prone to surface water flooding.
Forecasters predict that widespread rainfall totals could reach between 20mm and 30mm during the 12-hour warning period. However, isolated spots – notably those on higher ground – may experience significantly more, up to 50mm of rain in a short timeframe. This substantial amount of precipitation within a relatively brief period has raised concerns about urban drainage systems struggling to cope with water levels.
The majority of the South East England is under the yellow warning, encompassing Greater London, Kent, East Sussex, West Sussex, Surrey, and parts of Hampshire and Essex. Residents in other UK regions are also advised to remain vigilant for localised showers over the weekend.
Residents within the affected areas should exercise caution, as drivers will face reduced visibility, slippery road surfaces, and a heightened risk of aquaplaning. The public is strongly urged not to attempt driving or walking through floodwaters due to unpredictable depths and powerful currents. A small chance of power cuts and other service disruptions also exists.
Looking ahead to Sunday, the weather pattern is expected to gradually ease, with brighter and drier conditions across most of the UK. However, isolated showers may still occur. On Saturday, temperatures in southern English regions are forecasted to hover around 10-13°C, with light winds generally below 15mph, although gusts could be stronger in exposed coastal areas.
Local authorities and emergency services closely monitor the situation and are prepared for any incidents of flooding or disruption. Residents are advised to stay informed through local news and weather updates specific to their area.
