Italy, Croatia: Adverse weather forecast across central and southern Italy and most of Croatia through at least Nov. 19

Event

Strong winds, heavy rainfall, and thunderstorms are forecast across parts of central and southern Italy and most of Croatia through at least Nov. 19. As of early Nov. 17, authorities have issued the following weather warnings across the affected area:

• Orange thunderstorm warnings (the middle level on a three-tier scale): Tuscany Region in Italy.

• Orange heavy rain warnings: Rijeka Region in Croatia.

• Yellow thunderstorm, heavy rain, and wind warnings: the rest of the affected area.

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

Hazardous Conditions
Heavy rainfall could trigger flash and areal flooding in some areas. Such flooding is possible in low-lying communities near watercourses and other large bodies of water and in urban areas with easily overwhelmed stormwater drainage systems. Sites located downstream of large reservoirs may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly or mountainous areas. Power outages could occur throughout the affected areas.

Transport
The severe weather will likely contribute to transport disruptions throughout affected regions. 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 will likely cause flight delays and cancellations at airports across affected regions. Authorities may temporarily suspend port operations or close beach fronts if strong winds trigger hazardous sea conditions. Flooding could block regional rail lines; freight and passenger train delays and cancellations are likely in areas that see heavy rainfall and potential track inundation.

Advice

Monitor local media for weather updates and related advisories. Confirm all transport reservations and business appointments before travel. Make allowances for localized travel delays and potential supply chain disruptions in affected areas. Charge battery-powered devices in the case of prolonged electricity outages.
