Weather experts have warned that Storm Fleur could strike the UK days before the heatwave returns.
Met Office forecasters said another storm is likely to be named after the washout from Storm Evert last week.
They say Thursday could see a 400-mile-wide Atlantic storm with gusts of 60 mph.

The southwest of the country is expected to be the windiest. Flooding and highs of 20 ° C are expected this week alone.
Last week, Storm Evert hit parts of the country and produced gusts of nearly 70 mph across Cornwall and the Isles of Scilly, reports The Mirror.
The storm moved away from eastern England into the North Sea on Friday evening, carrying high winds with it.
Stifling heat is expected to bring warmer weather back into the second half of August, with temperatures of 31C posted on forecast models after mid-month. The Met Office also predicted mostly blue skies.
Forecaster Marco Petagna said: “Is the next named storm coming? There is potential, with a deep area of low that could turn wet and windy again around Thursday.
“The forecast models show a continuation of our cool and changing pattern for 10 to 14 days, but there are bullish signals for warmer high pressure to follow.”
Former BBC and Met Office forecaster John Hammond said: “People are wondering if fall has come early, but summer is not over.
“The energy from Canada’s jet stream will bring wet and windy weather this week, with more impacts also expected next week.
“But there is optimism for the hot spells from August 16, with a heat of 30 ° C certainly possible before the end of summer.”
A Met Office forecaster said: “Scattered showers get stronger on Wednesday, with blustery Thursday with more persistent rains – and unstable conditions dominate the first half of August. Torrential downpours are likely in places.
“August 15-29 has indicated above average temperatures, and possibly very hot conditions in the south at times. Most should see dry and beautiful weather.”
