The United Kingdom is known all around the world for three things: The Royal Family, tea, and the Great British weather.
The three elements are set to collide over the weekend, with worsening weather conditions threatening to dampen the Coronation celebrations.
A special flypast is at severe risk of being cancelled because of the poor outlook for Saturday.
With the forecast predicting wet and cloudy conditions on Saturday, a Ministry of Defence spokesperson has warned that the flypast may have to be scaled back or cancelled all together.
A tri-service flypast consisting of 60 aircraft, including the Battle of Britain memorial flight, the Red Arrows, modern F-35s and Typhoons, is due to take place on Saturday afternoon after the formal ceremony has come to an end.
Speaking to the PA news agency, a Defence spokesperson said: “There are certain weather limits in terms of cloud base and visibility for a flypast involving a large number of aircraft which will need to be met.
“The latest weather information will be obtained from both the Met Office and from our helicopters performing weather checks in advance of the main flypast on Saturday.
“If suitable, the flypast will continue as planned. If not, then there are options available to reduce the numbers of aircraft, with cancellation being the last resort.
“Clearly there are many things the MoD does control, but the weather is not one of them. Safety will always be our primary concern.”
