Brits are bracing for a deluge within days as the latest weather maps reveal a giant wall of rain charging towards us.

September is often a month of climatic contrasts, swinging from historic highs to icy lows and torrential rains. This year seems set to follow that unpredictable path, with brief summery skies giving way to overcast conditions and rainy spells.

Umbrellas at the ready: recent mapping by WXCharts using MetDesk data indicates a 363-mile-wide band of rain hitting by midday Tuesday, September 24. This extensive stretch of precipitation is expected to cover much of Scotland and parts of Northern England, including parts of the North East, and from Liverpool to Leeds across the Pennine ranges.

Yet another forecast suggests this system will engulf additional regions, with some of the highest rainfall rates centring around London. Estimates show the capital could experience up to 25mm of rain, whereas the Isle of Skye might endure the most intense drenching with approximately 36mm forecasted.

Moreover, wind speeds could escalate to 60km/h as the fierce weather system emerges from the Atlantic The phenomenon was elaborated on by Jim Dale, senior meteorologist at British Weather Services, who explained: "A 'wall of rain' can happen at any time of year. It's normally associated with an active frontal system.", reports the Mirror.

According to additional insights, prolonged dry conditions are predicted due to an extensive high-pressure system. However, he highlighted that "If it does unfold then it will occur after a lengthy high pressure dry spell. Not so uncommon in that respect but likely to have been invigorated by much above average/record Atlantic sea surface temperatures - additional heat energy in the atmosphere means it's able to hold more rainfall."

The Met Office has released their long-range weather forecast from Tuesday, Sep 17 until Thursday, September 26, suggesting earlier rainfall in the week. It stated: "Cloud and outbreaks of rain are expected to affect some northern areas for a time on Tuesday, with dry and sunny conditions further south."

The forecast continues, predicting that next week will see high pressure take the reins, ushering in predominantly dry and sunny weather throughout most of the UK. "Through the rest of next week high pressure will become more dominant, with dry and often sunny conditions spreading across the majority of the UK. Winds could be fairly strong at times in the south, with some overnight mist and fog in parts of the north."

Daytime temperatures are set to exceed averages across many regions, despite potential for chilly nights locally. "Temperatures during the day will likely be above average in many areas, although some cold nights are possible in places."

Looking ahead, the same pattern is expected to remain, with a note of speculation for what late September may hold: "A similar pattern will probably persist through the following week, although by late September there is a chance that more unsettled conditions may begin to develop."
