Trooping the Colour washout as thousands on Mall to be soaked in wet weather

Sadly, it appears the weather may put a small dampener on the event as WXCharts’ weather maps show.

The event starts at 10am and finishes by 12:25pm. The forecaster predicts that the rain will be falling as early as 9am, and could even start during the procession.

The Met Office has a similar forecast, warning of a 40 percent chance of rain at 10am on Saturday, just as the event is getting underway.

They add: “Sunny intervals changing to light showers by late morning.”

WXCharts shows the rain moving out of London at around 6pm.

The Met Office currently says there is a 60 percent chance of rain at 1pm, a 60 percent chance at 4pm, and a 40 percent chance at 7pm.

Despite the potentially gloomy weather conditions, King Charles has said he is looking forward to the event.

His Majesty, who is Colonel in Chief of the seven Guards regiments of the Household Division, inspected the guardsmen and officers on parade on Monday afternoon.

The monarch then said: “It has been a remarkable 84 years since my grandfather, King George VI, presented new Colours to the Second Battalion Irish Guards in Wellington Barracks during the opening months of the Second World War.

“After that terrible war, whose anniversaries we are in the midst of commemorating, the Second Battalion was placed in suspended animation but, I am delighted to say, has been reinstated.”
