The bad weather in the Region has had many flight circle for a while before being able to land. Easyjet Gatwick is one of these flights at the moment waiting for a break in the weather.
Low cloud and poor visibility will be the main problem.
I also see BA from Heathrow diverted, I presume to Porto Santo. The weather should start to improve, and hopefully flights will land OK, and BA should be back to the island also.
