Remnants of the hurricane are expected to hit the UK on Tuesday, after it has travelled across the Atlantic over the weekend.
Met Office meteorologist Alan Deakin said: “Hurricane Helene may influence things in combination with an area of low pressure over the coming days.
“Areas of low pressure containing what’s left of Storm Helene will still provide moisture and energy which will impact the UK quite a bit as we go into the early part of next week.
“There is a lot of uncertainty around the development of that low pressure system.”
The Met Office has claimed Helene, which is currently making its way through the Atlantic, could bring temperatures as high as 26C in the London area, while reaching only 6C in Scotland.
Marco Petagna, a Met Office forecaster, said: “Storm Helene is still in the Atlantic but it could have an influence in Britain next week.
“Remnants of that system could bring wet weather across western parts of the UK on Tuesday and we still need to keep an eye on it.
“But it could have a positive effect on eastern parts because it could also bring tropical air.”
