A blast of Caribbean hot air could push temperatures over that of Menorca, Majorca and Sardinia next week.
The air mass is set to continue the unseasonable warmth of the last week as parts of the UK prepare for highs of 16C or 17C on Monday.
The cloud of hot air is making its way over the Atlantic Ocean from Florida and parts of the Caribbean, and is expected to reach the British Isles over the weekend.
London is tipped as one of the likely locations for the highest temperatures, with the east of the country broadly enjoying the best of the warmth.
The rise could make the UK among the hottest locations in Europe, following bouts of snow and freezing temperatures that took hold earlier this month.
