Intense rainfall flooded parts of Crete, Greece's largest island, on Saturday, blocking roads with debris, trapping motorists and forcing some tourists to be evacuated, officials said. The island remained under a red alert, the highest level of weather warning, after 420 millimetres of rain fell in the Chania area in roughly a day and a half, while storm surges damaged the historic Venetian harbour in Chania, a major tourist hub. Strong winds also kept many ferries docked at mainland ports, and rescue crews worked to clear roads, free 23 people stranded near Ierapetra and reach eight park staff cut off in the Samaria Gorge national park, who were reported safe.
