It's the Western islands (Tenerife and Gran Canaria) that tend to cop it most, with these systems.
Today in Fuert is ok so far today, the odd shower, according to one of my pals there.
Mind you, about 7 years ago we had a bad storm in the early hours whilst in Fuert, woke us up at 6 in the morn. By the time we got out of bed at 9 it had cleared; a few puddles, plus loads of palm tree branches on the ground, were the only remaining evidence of the overnight storm.
