Heavy rainfall is poised to bring widespread flooding and significant disruption across large sections of the United Kingdom this Monday. An amber severe weather warning for rain is currently active across south Wales, with numerous yellow warnings covering many western areas of the nation.
Millenium TV has learned that nearly a month’s worth of rain could inundate ground already heavily saturated from above-average rainfall throughout November across England and Wales. Gusty winds are also anticipated, particularly along coastal regions.
The meteorological winter has commenced with exceptionally wet conditions across much of the UK, a trend expected to persist through Monday with periods of particularly intense downpours. As rainfall totals accumulate on already sodden ground, multiple yellow weather warnings remain in effect.
The more critical amber warning for south Wales will remain active until 21:00 GMT. Between 20 and 40mm (0.8 and 1.6in) of rain is broadly expected in this region, with some south-western facing hills potentially receiving closer to 120mm (4.7in). For context, the average rainfall for south Wales and south-west England for the entire month of December is typically 152mm (6in). Extensive flooding is possible, threatening disruption to road and rail networks, potential power outages, and the risk of communities becoming isolated. Authorities have also cautioned that fast-flowing or deep floodwater poses a significant danger to life.
Additional yellow weather warnings are in place for:
* South-west Scotland until 21:00 on Monday
* North-west England and parts of the West Midlands until 23:59 on Monday
* Most of Wales and south-west England until 21:00 on Monday
These areas are also forecast to see between 20 and 40mm of rain widely, with higher elevations such as the Cumbrian Fells and Eyri potentially experiencing 80 to 120mm (3 to 4.7in). This could lead to localized flooding and further transport delays. Parts of East Yorkshire have already witnessed flooding this Monday morning, requiring emergency services to pump water from affected properties.
Flood management agencies have issued warnings across affected regions. Officials are urging the public, stating, “We urge people not to drive through flood water – it is often deeper than it looks and just 30cm (1ft) of flowing water is enough to float your car.” Strong winds are also expected to accompany the heavy rain, with gales possible along coasts and over high ground.
November proved to be exceptionally wet, especially across England and Wales. Recent meteorological data reveals it was the wettest month of 2025 so far, recording rainfall 31% above the average. In parts of eastern England, some weather stations have even registered their highest November rainfall on record. For instance, Bridlington, Yorkshire, received nearly three times its normal rainfall with 180mm recorded, compared to an average of 66mm – marking a new November record. Other areas in East Yorkshire and Lincolnshire experienced more than double their usual rainfall, leading to their wettest November on record.
This autumn stands as the only season this year to record above-average rainfall, with the UK as a whole seeing 20% more than the long-term meteorological average, and Northern Ireland and Wales experiencing significantly higher amounts. Despite the increased rainfall, autumn continued the trend of above-average temperatures in 2025. However, with a mean temperature of 0.4C above the seasonal average, no temperature records were broken.
