Greece: Adverse weather forecast across eastern, northern, and western regions May 16
Severe weather forecast across eastern, northern, and western Greece May 16. Disruptions to transport, business, and utilities possible.
Event
Severe weather is forecast across much of eastern, northern, and western Greece on May 16. Thunderstorms accompanied by heavy downpours, strong wind gusts, lightning, and possible hail storms are expected across the affected area. Heavy downpours associated may trigger flooding in low-lying areas, and strong winds could cause property damage and power outages.
As of May 16, authorities have issued the following weather warnings across the country:
Orange thunderstorm warnings (the middle level on a three-tier scale): Eprius and the Ionian Islands regions.
Yellow thunderstorm warnings: Across the rest of the affected area.
Yellow strong wind warnings: Ionian Islands and West Peloponnese regions.
Authorities will likely 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 heavy rainfall has saturated the soil.
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 cancelations 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.
