Nigel’s arrival will come days after Hurricane Lee, which is currently battering parts of Wales, north-west England and parts of Scotland.
The remains of a second hurricane will sweep across the UK later this week, bringing more heavy rain and thunderstorms.
Hurricane Nigel formed in the middle of the Atlantic Ocean over the weekend and strengthened Tuesday as it moved north toward Europe.
And although it is expected to weaken in the coming days, the storm will create more unstable conditions and make its presence felt here.

Met Office spokesperson Grahame Madge said: “These systems are long-range, they will increase rainfall rates and also winds to bring unsettled weather to the UK.”
Nigel’s arrival will come days after Hurricane Lee, whose tail is currently lashing parts of Wales, north-west England and parts of Scotland.
There are yellow weather warnings for rain, some until Wednesday night, amid fears that homes and businesses could be flooded in the worst-affected areas.
Some western areas could see 100mm of rain, rising to 200mm in higher altitude areas such as Eryri National Park, also known as Snowdonia.
Forecasters say bus and train services could face delays over the next 24 hours, but the rainfall will not compare to the “intense amounts” seen last weekend, when more than 10,000 lightning strikes were recorded. with flash flooding reported at a Butlin resort and Exeter Airport.

Madge added: “Although we have indicated that there could be flooding associated with reasonably high levels of rainfall, it is not something that is anticipated to be widespread.
“It’s something that can be a consequence of a basin suddenly becoming more flooded or there are blockages in the drainage.”
He went on to explain that Hurricane Lee brought more moisture to the UK, along with higher air temperatures, resulting in higher levels of rainfall.
