Two people have died and one has been reported missing in the central region of Thessaly after the Mediterranean hurricane, Medicane Ianos, pounded parts of Greece overnight and caused flooding.
Authorities said the two victims were an elderly woman found dead in her flooded home and a 63-year-old shepherd who was swept away by flood waters.
A woman was missing after she ignored police and firefighter instructions not to drive into an area where a bridge spans a river, they said.
The Greek fire service said on Saturday it had fielded almost 2,500 calls from people either trapped in central and western regions or requesting the removal of fallen trees that were blocking roads or had caused property damage.
The service reported rescuing more than 600 people.
The train operator, Trainose, said the service linking southern and northern Greece was suspended.
Water from a flooded river damaged at least two bridges and several buildings, including the local health centre in the Thessaly town of Mouzaki. Parts of the area had no electricity.
Greece was hit by a similar storm in 2018. A year earlier, flash floods left 25 people dead and hundreds homeless in western Athens. Many of the victims were elderly people whose bodies were subsequently found inside their homes.
