The Met Office has issued a fresh yellow weather alert for heavy rain across large parts of southern England, warning of potential flooding and significant travel disruption.
Warning Details and Affected Regions
The warning is in force for Thursday, 15 January 2026, and covers London, South East England, and South West England. Forecasters predict intense downpours could bring up to 30mm of rainfall widely, with isolated spots potentially seeing 50mm within just a few hours.
This deluge is set to fall on ground already saturated from recent winter weather, dramatically increasing the risk of surface water flooding. The public is advised that this could lead to flooding of homes and businesses, as well as causing delays and cancellations for bus and train services.
Context and Public Safety Advice
This new alert follows closely on the heels of Storm Goretti, which battered the UK last week with hurricane-force winds, triggered a rare red weather warning for Cornwall, and dumped significant snow elsewhere.
The Met Office is urging residents in the affected areas to take precautions. Key advice includes checking if your property is at risk of flooding, preparing an emergency flood kit with essential items, and verifying road conditions before setting out on any journey.
Potential Impacts and Looking Ahead
The primary concerns are localised flooding and hazardous travel conditions. The combination of high rainfall rates and wet ground means water will not drain away easily, leading to a heightened risk of roads becoming impassable and localised flooding of properties.
With the memory of Storm Goretti's impacts still fresh, authorities are emphasising vigilance. The public is encouraged to stay updated with the latest forecasts and warnings from the Met Office and local flood authorities throughout Thursday.
