Severe weather warnings have been issued across southern England and south Wales as forecasts predict more than a month’s worth of rain to fall within just two days, prompting concerns over flooding, disrupted travel, and potential power outages. The Met Office has highlighted the dangers associated with this intense rainfall, which is set to impact areas already weathered by a notably dry August.
Weather Warnings and Expected Conditions
The Met Office has placed a yellow weather warning for heavy rain in effect until 11:45 PM on Thursday, covering much of southern England and south Wales. The agency anticipates that some locations may receive up to 100mm (approx. 4 inches) of rainfall, significantly exceeding the average monthly precipitation for September, which normally ranges between 60mm and 90mm.
On Thursday, heavy showers are forecasted to transition into more persistent rain throughout the day. Rainfall rates expected during this time are alarming, with estimates suggesting approximately 20-40mm (about one inch) of rain may fall within just a couple of hours. While not every area under warning will be deluged, some could see totals exceeding 50-60mm (around two inches) over a longer duration.
Moving into Friday, another yellow weather warning will remain active, indicating that similar areas will endure another potential rainfall of 75-100mm (3-4 inches). Met Office spokespersons have noted the likelihood of impacts due to the compounded effects of an already wet day preceding further rainfall.
Potential Impact on Communities and Travel
Officials have alerted residents to the possibility of flooding affecting homes and businesses, alongside potential power outages. Travel delays are further expected, particularly on roads, where hazardous conditions such as spray and sudden flooding may arise.
In response to these severe weather conditions, London Gatwick Airport has implemented temporary air traffic control restrictions, which have led to delays in some flights. A spokesperson from the airport urged passengers to check with their airlines for more accurate information regarding potential travel disruptions.
Additionally, notable disruptions have been reported on the rail network. Train services between Ramsgate, Kent, and London Charring Cross have faced delays due to a tree on the line, while injuries to track caused by standing water have disrupted routes between Farnham, Surrey, and Aldershot, Hampshire.
Flood Alerts Issues and Community Safety
The Environment Agency has issued multiple flood alerts, warning residents of possible flooding scenarios in various local streams and rivers, including the Scrase Bridge and West Common streams in Haywards Heath and Lindfield. They reported that recent rainfall has caused water levels to rise dangerously in some areas, increasing the likelihood of flooding affecting commercial and residential properties.
Chief meteorologist Jason Kelly emphasized the persistent nature of the rainfall, indicating that widespread totals of 15-30mm are foreseen, though the wettest regions might experience levels of 40-60mm by the end of Friday. Thunderstorms may accompany these rainfalls, especially in the South East.
Weather Outlook for the Weekend
The persistent rain is forecasted to continue into the weekend, with conditions remaining unsettled across the southern UK. Despite earlier predictions of warmer weather, recent statements from the Met Office clarify that no extreme heatwaves are expected to impact the UK as they did in the previous year. In fact, areas including western Scotland might reach temperatures around 25°C, while the South is likely to remain draped in clouds and rain.
As the storm system expands, the east of the UK is anticipated to experience cooler and cloudier weather while the northwest should enjoy a burst of sun and warmer conditions. However, the ongoing risk of heavy rain and thunderstorms may result in sporadic travel issues.
Further Developments and Precautions
Looking ahead, forecasters predict a mixture of cooler, wetter interludes and potential settled weather across the UK. Slightly below average temperatures are anticipated to return to southern areas, while the northern part of the country may see more stable weather through mid-next week.
Residents in affected areas are urged to monitor local alerts from the Met Office and Environment Agency, ensuring they remain prepared for possible floods, travel disruptions, and adverse weather conditions. Local authorities recommend having an emergency plan in case sudden flooding cuts off access or intrudes into homes and businesses.
Summary of Rainfall Impact
As southern England and south Wales brace themselves for heavy rainfall, residents are reminded to stay informed and take necessary precautions to ensure their safety. The upcoming days will see weather forecasters closely monitoring conditions as they unfold, with communities hoping for relief as water levels are expected to rise after more than a month’s worth of rain falls within a very short period.
