Weather Forecast Uk London

Flash floods tipped after heatwave

The Environment Agency and Met Office have warned of localised flooding in London, the South East and eastern England, saying up to 40mm of rain could fall in the space of a few hours.

Hail storms are also expected as the weather makes an abrupt U-turn following the hottest day of the year so far on Monday.

The Environment Agency has issued a flood alert for rivers in the London Boroughs of Lewisham, Bromley, Greenwich and Croydon, with up to 30mm of rain predicted. Surface water flooding could also occur in other regions hit by heavy storms.

An Environment Agency spokesman said: "Environment Agency staff are on 24-hour alert and teams are monitoring river levels as the band of rain moves across the country. The public is encouraged to tune in to local media for weather forecasts for their area and to keep an eye out for signs of surface water flooding."

The threat of heavy rain comes after temperatures soared in a heatwave that saw the mercury reach 32.8C in Gravesend, Kent, in the hottest day of the year so far.

A Met Office spokesman said the "sheer volume of rainfall falling in such a short space of time" in some areas could lead to surface water flooding in some places. But the extremely dry spring, which has left some parts of east and central England officially in a state of drought, means that most rivers are at low levels and are unlikely to flood.

According to MeteoGroup, the weather division of the Press Association, showers and thunderstorms are expected in south east England and East Anglia.

Temperatures in London are not forecast to climb higher than 23C, while the west and the north will even see the weather turn chilly.

Tom Tobler, a forecaster at MeteoGroup, said: "There will be heavy showers and thunder storms developing in South East England and East Anglia during the morning. There will be a risk of localised flash flooding but during the afternoon and evening the storms should clear eastwards.

Weather forecast for the Royal Wedding Day in London the UK ...

April.

Probably nothing will spoil the special day for the happy couple but for them, the guests who have also turned out in their finery and the millions of people expected to line the processional route between Buckingham Palace and Westminster Abbey and back again, what will the weather be like?

The people planning celebratory street parties up and down the country will also probably be interested in what the weather forecast is expected to be on Friday. Want to know more - well let's look into our weather forecasting crystal ball...

Weather forecasting seems to be a 'dark art' here in the UK and our crystal ball predicts some heavy showers for the Royal Wedding in London on Friday. That is a particular shame as for the last few days most of the country has basked in sunshine which is not at all typical for April. Temperatures on 29 April are still predicted to be warmer than average for the time of year, but by Friday, conditions will be cooler and cloudier than they have been, with heavy downpours of rain expected both for Central London and for Catherine Middleton’s hometown of Bucklebury in Berkshire.

Temperatures are likely to be in the high teens (Celsius), high sixties Fahrenheit all over the country. That is quite warm for this time of year but the wind will probably stronger by Friday when some heavy showers become likely. It may feel cool compared to the wonderful weather experienced practically all over England over the Easter weekend, even between the showers.

Northern and Western areas are likely to see the best of the weather on Friday. That is unfortunate for the Royal couple, given that their wedding will take place in the South West but hopefully they will be able to dodge the rain showers on their horse-drawn carriage ride back to Buckingham Palace after the wedding ceremony. The rest of the day they can stay under cover inside or in the cars that will transport them to the wedding.

The forecast so far for Friday indicates that the rain will fall on Central London later in the afternoon. As the wedding of Prince William and Catherine Middleton is due to take place at 11am, they should not be bothered by the showers. They should be inside, enjoying their reception by the time the rain comes. However, tourists and patriotic well-wishers wanting to celebrate with a London street party might not be so lucky.

Of course, exact weather predictions are difficult to give for three days’ time, but if the Met Office announces any major deviation from the warm but showery wet outlook we have at the moment, we will update this page.
