Hurricane remnants bring rainfall
The remnants of Hurricane Ophelia will lash Britain with strong winds and rain this week, forecasters said.
But much of England and Wales will see the unseasonably warm weather continue for another two days at least.
Andy Ratcliffe, a forecaster with MeteoGroup, said the remains of the hurricane, currently hitting north America, will affect Scotland, Northern Ireland and the North West of England from Wednesday. "That will bring strong winds and rain to north western parts of the UK," he said.
But the mini-heatwave continued in England and south Wales on Sunday, with the mercury peaking at 29.4C at RAF Mildenhall, Suffolk, around 3pm, a new record for October 2.
The UK's hottest day of 2011 was June 27 when a temperature of 33.3C (91.9F) was recorded at the Olympic Park in London.
But not everyone in Britain shared in the heatwave. While many headed for beaches and parks, rain fell on North Wales, most of the north of England, Scotland and Northern Ireland with temperatures hovering around 15C.
Many feared the worst for the country's motorways but traffic remained at "normal Sunday levels" as of 4pm.
Andrea Day, communications manager, Trafficlink, which provides live travel news, said: "The M40 is a little busy around Buckinghamshire towards London and there's a bit of traffic on the A1 near Newcastle, but it's nothing that's ringing too many alarm bells.
"It's a normal, busy Sunday afternoon with people heading back home for the working week."
People in England and Wales can look forward to basking in more warm weather as the working week begins, with highs of around 25C. "Tomorrow much of England and Wales will continue with plenty of sunshine," said Mr Ratcliffe.
