Rising water levels at Lake Karla are threatening to inundate the few remaining parts of the Thessalian plan that have not yet flooded, as the waters from the Pineios River continued to feed into the lake on Friday. Villages on the lakeshore, such as Stefanovikio, Rizomylos and Kanalia, received a 112 alert on Thursday night, urging residents to remain vigilant.

Meanwhile, the city of Volos remained without safe drinking water, with authorities warning of the danger of disease, for the 11th consecutive day as the capital of flood-stricken Magnesia struggled to overcome the serious problems in the wake of Storm Daniel.

Apart from the mud left behind after the water receded, many of the city's businesses are unable to operate due to a lack of water - including dairy and soft drinks manufacturing units, as well as heavy industry that uses water for cooling - and because the mud has destroyed basic equipment.

The lack of clean water is also a blow to the city's hospitality sector, such as bars and restaurants, while the city's hotels are empty due to mass cancellations of bookings.
