Torrential rain battered central Greece, flooding streets, homes and businesses in the city of Volos just three weeks after devastating Storm Daniel killed 16 people in the wider region.
More than 250 people have been evacuated from the area since Storm Elias struck on Wednesday afternoon, the fire brigade said on Thursday, adding that it had so far received 1,200 calls for help.
The storm hit Volos with rain so heavy that water levels in the city and its suburbs rose rapidly in a few hours. A nearby stream overflowed, adding to the flooding.
The mayor of Volos said that by Wednesday night, power outages caused by the storm and flooding had plunged 80% of the city into darkness. Authorities have stopped all vehicles from going onto the roads.
"People can't stand this anymore. I cannot understand nature's rage. Protect yourselves," said Mayor Achilleas Beos, urging people to stay home.
By Thursday morning, the storm had moved towards the island of Evia, a fire brigade official said. Some villages in northern Evia have been ordered to evacuate, state ERT TV said.
Storm Elias is the second major storm to hit the region since Daniel, the most intense storm to hit Greece since records began in 1930, battered the region for three days earlier in September.
Many Volos residents said the authorities were still dealing with the aftermath of Daniel and had not been adequately prepared for another storm.
"This was foretold," said Yannis Gavanoudis, a 70-year-old pensioner. "They (authorities) didn't do their job properly."
Daniel turned central Greece into an inland sea, flooding homes, damaging road infrastructure and farms near Volos, Karditsa and Larissa.
Tens of thousands of animals drowned and crops were washed away, and residents of the flooded areas are still struggling to recover from the impact.
Storm Daniel also wrought devastation across the Mediterranean, moving from Greece to Libya, where over 2,500 died in a huge flood in the city of Derna.
