Italy: Adverse weather forecast across much of the country through at least Nov. 5
Severe weather forecast across much of Italy through at least Nov. 5. Transport, business, and utility disruptions possible.
Event
Heavy rainfall, thunderstorms, and strong winds are forecast across much of Italy through at least Nov. 5. Storms may be accompanied by lightning and possible hail storms. As of early Nov. 3, officials have issued the following weather warnings across the country:
Orange thunderstorm warnings (the middle level on a three-tier scale): Lazio, Liguria, and Tuscany regions.
Orange heavy rainfall warnings: Aosta Valley, Emilia-Romagna, Friuli Venezia Giulia, Lazio, Liguria, Lombardy, Piedmont, Trentino-Alto Adige, Tuscany, and Veneto regions.
Orange strong wind warnings: Emilia-Romagna Region.
Yellow thunderstorm, heavy rainfall, and strong wind warnings: the rest of the country.
Officials could update and possibly extend the coverage of weather alerts over the coming days.
Hazardous Conditions
The storms could produce rounds of heavy rainfall, strong winds, and isolated thunderstorm activity across the affected area. 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 or lack of 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. Power outages could occur throughout the affected area.
Transport
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. The disruptive weather may cause some delays and cancellations at airports in the worst-affected regions. Authorities may temporarily suspend port operations if strong winds trigger hazardous sea conditions, impacting freight and passenger maritime traffic. Flooding could block regional rail lines; freight and passenger train delays and cancellations are possible in areas with heavy rainfall and track blockages.
Advice
Monitor local media for weather-related updates and advisories. Confirm all transport reservations. Stay away from elevated streams, creeks, and other watercourses that are prone to flash flooding. Do not attempt to navigate flooded roadways. Exercise caution in elevated terrain due to the threat of landslides. Charge battery-powered devices in the case of prolonged electricity outages.
