Croatia: Adverse weather forecast across much of the country through at least Oct. 11

Severe weather forecast over much of Croatia through at least Oct. 11. Disruptions to transport, business, and utilities possible.

Informational

Severe weather is forecast across much of Croatia through at least Oct. 11. Heavy rainfall and thunderstorms are expected across the region over the coming days; strong wind gusts, lightning, and hail may accompany storms. Heavy downpours could trigger flooding in low-lying communities, and strong winds could cause property damage and power outages.

Croatia's State Hydrometeorological Institute (DHMZ) has issued the following weather warnings across the affected area Oct. 8-9:

Oct. 8

  • Orange heavy rainfall warnings (the middle level on a three-tier scale): Gospic and Rijeka regions.

  • Orange strong wind warnings: Most central and northern coastal waters.

  • Yellow thunderstorm warnings: Gospic, Knin, Rijeka, and Split regions.

  • Yellow strong wind warnings: Gospic, Knin, Rijeka, and Split regions and some central and southern coastal waters.

Oct. 3

  • Orange thunderstorm warnings: Dubrovnik, Knin, and Split regions.

  • Yellow heavy rainfall warnings: Dubrovnik, Gospic, Knin, Rijeka, and Split regions.

  • Yellow thunderstorm warnings: Gospic and Rijeka regions.

  • Yellow strong wind warnings: Dubrovnik, Gospic, Knin, Rijeka, and Split regions and most coastal waters.

Officials could update and possibly extend the coverage of the weather alerts over the coming hours and days.

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. Where significant flooding, landslides, or strong winds impact utility networks, disruptions to electricity and telecommunications services are possible.

Floodwaters and debris flows may render some bridges, rail networks, or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters. Strong winds might also pose a hazard to high-profile vehicles.

Severe weather could also trigger flight delays and cancellations at airports across the affected areas. Authorities may temporarily suspend port operations or close beach fronts along the Adriatic coast if strong winds trigger hazardous sea conditions. Flooding could block regional rail lines; freight and passenger train delays and cancellations are possible in areas that see heavy rainfall and potential track inundation.

Localized business disruptions may occur in low-lying areas; some businesses might not operate at full capacity because of flood damage to facilities, possible evacuations, and some employees' inability to reach work sites.

Monitor local media for updated emergency and weather information. Seek updated information on weather and road conditions before driving or routing shipments through areas where severe weather is forecast. Plan accordingly for potential delivery delays if routing shipments by truck through affected areas. Confirm flights. Charge battery-powered devices in the case of prolonged electricity outages.
