Overview

• The UK’s fourth summer heatwave has ended, ushering in a mostly dry, cooler phase with isolated thundery showers.
• The Met Office’s long-range outlook forecasts initial high pressure giving way to a deep Atlantic low linked to Tropical Storm Erin around August 26–27.
• WXCharts and Ventusky models project a 600-mile rain band late this month, with up to 18–31 cm possible in Welsh high ground, though timing remains uncertain.
• Tropical Storm Erin has already caused evacuations and fatalities in Cape Verde and is being tracked by the National Hurricane Center as it moves northward.
• Several English regions remain under 'nationally significant' drought or prolonged dry designations, heightening concerns over water resource management and wildfire risk.
