The Met Office has issued a yellow weather warning for heavy rain across South London, alerting residents to potential disruptions and hazards on Tuesday, January 27, 2026.
Warning Details and Timing
The warning is in effect from midnight until midday on Tuesday, covering a large swathe of South London. Areas such as Croydon and Orpington, along with their surrounding regions, are specifically highlighted as being at risk.
Expected Rainfall and Impacts
Forecasters predict that spells of heavy rain overnight into Tuesday morning could lead to accumulations of up to 25 mm in affected areas. This significant rainfall raises concerns about possible flooding and transport disruption, including delays to road and rail services.
The Met Office has emphasised that the heavy downpours, moving eastwards, may cause localised issues, particularly in low-lying or poorly drained spots. Residents are advised to stay updated with the latest weather alerts and plan their journeys accordingly.
Broader Regional Impact
Beyond London, the yellow rain warning also extends to other southern parts of the country. Coastal areas, including Brighton and Portsmouth, are similarly affected, indicating a wider weather system impacting the region.
Forecast for the Rest of the Day
Despite the wet start, conditions are expected to improve as the day progresses. Forecasts indicate that the rain should clear by early afternoon, with drier weather prevailing for the remainder of Tuesday and into the evening.
The Met Office's official forecast for Tuesday states: "Outbreaks of rain, heavy at times, moving eastwards. Becoming dry from the west during the afternoon, but further evening showers following." This suggests a brief respite before potential showers later in the day.
Precautionary Measures
In light of the warning, authorities recommend that individuals in South London take precautions to mitigate risks. This includes:
- Checking travel updates before setting out
- Avoiding flooded roads and pathways
- Securing outdoor items that could be affected by strong winds or heavy rain
Staying informed through official channels, such as the Met Office website or local news, is crucial for real-time updates on the situation.
