Greece is facing one of its most severe weather systems of the year as Storm Byron continues to sweep across the country, bringing torrential rain, powerful winds, widespread flooding, and major disruptions from Athens to the islands. Authorities have issued a “red alert” warning for many regions, urging residents to avoid unnecessary travel and stay indoors until conditions improve.
Storm Byron began intensifying mid-week and is expected to continue affecting large parts of the country until Saturday midday, according to the Hellenic National Meteorological Service (EMY). The storm has already caused road closures, landslides, power outages, and significant damage in several regions, with emergency crews responding to flooded homes, stranded motorists, and overflowing rivers.
Major Areas Impacted
Attica, the Peloponnese, Central Greece, western and southern Crete, the Dodecanese, and parts of the Aegean islands are among the hardest hit. Heavy rainfall has led to blocked roads in Athens and Piraeus, while islands such as Crete and Zakynthos have reported landslides and severe flooding. Several municipalities have also announced temporary school closures as a precaution.
Travelers are being warned to expect ferry cancellations and flight delays, especially in island regions experiencing strong winds and lightning storms. The Athens–Corinth highway experienced temporary closures due to flooding, adding to significant transport disruption.
How Long Will the Storm Last?
The current weather front is forecast to gradually weaken starting late Friday night, with significant improvement expected by Saturday midday. Meteorologists warn, however, that water levels in some rivers and streams may continue to rise even after rainfall slows, meaning localized flooding remains possible.
Expats living in coastal or low-lying areas should remain alert, especially in regions that have previously experienced flood damage.
What Expats Should Know and Do Right Now
Authorities have issued warnings via Greece’s 112 emergency alert system, advising residents to stay away from basements, rivers, ravines, seafronts, and areas with poor drainage. For expats who may not be familiar with Greek emergency procedures, here are key reminders:
- Avoid unnecessary travel until weather conditions stabilize.
- Stay updated through official channels such as EMY, local municipalities, and Civil Protection.
- Prepare for power or internet outages, particularly in rural or island areas.
- Secure balconies, terraces, and outdoor items, as strong winds may cause damage.
- Check on neighbors or fellow expats, especially those who may not speak Greek or understand emergency alerts.
- Follow all evacuation instructions issued through the 112 alert system — these are not optional.
For those living in ground-floor or basement apartments, precautionary steps such as moving valuables to higher shelves or temporarily relocating may be advisable until the storm passes.
Travel & Daily Life Disruptions
Public transportation disruptions are expected, particularly for ferry routes connecting the islands with the mainland. Airlines are monitoring the situation closely, and passengers are encouraged to check flight status before heading to airports. Schools across several islands and affected municipalities remain closed until conditions improve.
Businesses in flood-hit areas may also experience delays or temporary closures, so expats should prepare for potential changes to work schedules, deliveries, or appointments.
What Comes Next
While the worst of Storm Byron should ease by Saturday, cleanup and repair efforts may continue into next week. Authorities are urging residents to remain cautious even after skies begin to clear. Flooded roads, weakened structures, fallen trees, and unstable ground may present ongoing hazards.
For expats, this storm is a reminder that Greek winters — though mild compared to northern Europe — can still bring extreme weather, especially as climate patterns shift. Staying informed and prepared is key.
