Storm Agneta is in full force, causing serious problems across many parts of Greece, with heavy rainfall, flooded roads, overflowing streams, and damage to homes and infrastructure. Samos, Volos, Lemnos, Kalymnos, and Kimolos have already been hit hard by the severe weather, while Rhodes remains on high alert after an emergency warning was issued via the 112 emergency alert system in the early hours of Monday.

Samos: Roads and homes flooded — major Fire Brigade response
The heavy overnight rainfall on Sunday caused serious problems in Samos, where roads turned into raging torrents and flooding was recorded in residential properties.
The situation was particularly dire in the Heraion area, according to samos24.gr, where more than six Fire Brigade vehicles were deployed. Firefighting units received multiple calls to pump water out of flooded homes.
Video footage from the area captures the sheer force of the floodwaters, with one person struggling to cross a flooded road and barely managing to keep their balance.
Two excavators and a loader from the Municipality of Eastern Samos also joined the response effort, working in coordination with the North Aegean Regional Authority.
Due to the extensive water accumulation, authorities advised drivers to avoid the route from the airport to Heraion.
Flooding also hits Kalymnos and Kimolos
The severe weather also caused problems on Kalymnos, where heavy rain led to the accumulation of large volumes of water at low-lying points of the road network, significantly disrupting traffic.
Localised flooding was also recorded on Kimolos, with streets and narrow alleyways inundated by large quantities of water.
Residents in the affected areas remain on alert, as continued rainfall is increasing the risk of further problems.
Volos: Homes flood in Nea Anchialos — streams overflow
The storm also caused severe problems in the greater Volos area, with Nea Anchialos and Chrysi Akti Panagias among the locations that bore the brunt of the rainfall.
In the Alonaki district of Nea Anchialos, the Fire Brigade received five calls for assistance. One vehicle was buried under mud and debris and sustained material damage, while floodwaters also entered a residential property.
In Chrysi Akti Panagias, a stream burst its banks due to the sheer volume of water, causing problems throughout the area. Heavy machinery was deployed to clear the floodwaters and remove fallen trees.
Flooding was also recorded in the Palaia district, on Larisis Street, and in Nea Ionia.
Particularly striking images emerged from the intersection of Isidorou and Vyvantiou streets in Nea Ionia, where floodwaters rose so high they reached almost to the waist level of a parked car.
The situation in Alonaki was particularly dire, with roads turning into torrents, homes flooding, and cars being swept away by the water. Damage was also reported to key local infrastructure, including the sewage network and street lighting.
According to gegonotanews, problems had already been reported from Sunday midday and afternoon, when several roads in Volos turned into rivers due to the intense rainfall.
Lemnos: Muddy floodwaters reach the sea — road surface collapses
The storm also caused significant problems on Lemnos, particularly in the Myrina area, where powerful stream currents swept large quantities of soil, mud, and debris downstream.
According to limnoslive.gr, the sea at Romeikos Gialos turned brown as large volumes of muddy water emptied into it.
Concern was also raised by the intense flow in the Agia Triada stream, while at the Romeikos bridge, footage captured floodwaters rushing beneath the structure with tremendous force.
In Nea Madytos, rocks, gravel, branches, and debris accumulated, while the large volume of water flowing near drainage pipes caused damage to the road surface — in some spots, sections of the asphalt actually collapsed.
Problems from the heavy rainfall were also reported on Thasos, where streets and alleyways flooded.
