The Met Office says high pressure, which has kept conditions settled and cool, will be pushed aside by powerful Atlantic systems linked to Hurricane Erin by the end of the month
Britain is bracing for a dramatic weather shift at the end of August, with forecasters warning of torrential rain, powerful winds and plummeting temperatures.
Weather maps, generated by WXCharts on August 17 using Met Desk data, reveal a massive band of rain sweeping across Ireland and the UK on Wednesday, August 27 at 12pm, set to deliver heavy downpours. The Met Office says high pressure, which has maintained settled and cool conditions, will be swept away by mighty Atlantic systems connected to Hurricane Erin.
Charts from WXCharts indicate the initial signs of the storm will emerge in 10 days, before a wall of rain batters in from the west on Thursday morning.

Fierce bursts, highlighted in red and yellow on the maps, are poised to strike Ireland, Wales and western England before moving eastwards throughout the day, reports the Express.
The downpour will coincide with a dramatic temperature plunge, with parts of the country expected to be 14C cooler than recent peaks. This summer, sections of the UK were hammered by four heatwaves, with the mercury hitting 34C in July in London.
Charts indicate that on August 26 England may still swelter under 28C highs – only for temperatures to tumble to the low 20s in southern parts of Britain and low to mid 10s in Scotland.
A Met Office long-range forecast for August 22-31 stated: “High pressure is likely to be the dominant feature at first bringing widely fine and dry weather whilst a generally northerly flow leads to rather cool conditions.
“This will be increasingly eroded from the west as frontal systems start to move in from the Atlantic through the weekend, leading to more changeable conditions. A deep area of low pressure is likely to develop in the North Atlantic, linked to Hurricane Erin, and may progress towards the UK.”
Whilst the precise path of the storm remains unclear, weather experts say northern and western regions will face the harshest conditions. There’s also a small but increasing chance of widespread wet and blustery weather across much of the UK as we head into the final days of August.
The alert comes just weeks after Britain suffered through a stuttering summer of unsettled periods, sparking concerns of a complete washout for the season’s last bank holiday.
