Excitement over the royal wedding might be dampened by forecasts of heavy showers on the big day.
Following an uncharacteristically hot Easter Sunday, downpour is set to hit central London.
Helen Rossington - a senior forecaster at MeteoGroup - said: "At the moment, it is looking like temperatures will probably be a little bit above average (on the day) and there is a risk of heavy showers."
"Temperatures will probably be somewhere in the high teens but it is difficult to pin down so far ahead."
If it rains the royal couple will leave Westminster Abbey in the Glass Coach rather than the open-top State Landau.
