Greece: Adverse weather forecast across much of the country through at least Dec. 11
Severe weather forecast across much of Greece through at least Dec. 11. Disruptions to transport, business, and utilities possible.
Event
Severe weather is forecast across much of Greece through at least Dec. 11. As of Dec. 9, the Hellenic National Meteorological Service has issued an Orange level (the middle level on a three-tier scale) Emergency Bulletin of Weather Bulletin, warning that weather conditions will worsen from the northwest Dec. 10 before the adverse weather spreads across much of the country through Dec. 11. Heavy rainfall and thunderstorms will be accompanied by strong winds and possible hail. The most intense weather is expected in parts of Epirus, western Sterea, western Peloponnese, and western Thessaly regions overnight Dec. 10-11. As of Dec. 9, authorities have issued yellow thunderstorm warnings for the Ionian Islands and Epirus regions. Authorities will almost certainly issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.
Hazardous Conditions
Sustained heavy rainfall could trigger flooding in low-lying communities near rivers, streams, and creeks. Urban flooding is also possible in developed areas with easily overwhelmed stormwater drainage systems. Sites located downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly or mountainous areas, especially where the soil has become saturated by heavy rainfall.
Authorities could issue mandatory evacuation orders for flood-prone communities over the coming days. Disruptions to electricity and telecommunications services are possible where significant flooding or landslides impact utility networks.
Transport
The severe weather could contribute to transport disruptions throughout the region. Traffic and commercial trucking delays might occur along regional highways. Flooding downpours could inundate some low-lying roads in areas with poor drainage. Strong winds might also pose a hazard to high-profile vehicles. Hazardous weather conditions might cause flight delays and cancellations at airports in affected areas. Authorities may temporarily suspend port operations or close beach fronts if strong winds trigger hazardous sea conditions.
Advice
Monitor local media for weather-related updates and advisories. Confirm all transport reservations. Stay away from streams, creeks, and other watercourses that are prone to flash flooding. Do not attempt to navigate flooded roadways. Charge battery-powered devices in the case of prolonged electricity outages.
