The low-pressure system that has persisted offshore from Crete since yesterday is keeping the weather unsettled, with heavy rain and thunderstorms on the island, according to meteorologist Giorgos Tsatrafilias.

The phenomena will occur intermittently throughout the day and caution is advised, as there is a risk of flooding in vulnerable areas.
