Italy: Heatwave forecast over much of the country through at least June 24
Heatwave forecast over most of Italy through at least June 24. Hot weather likely to exacerbate ongoing drought situation in northern Italy.
Event
Forecast models indicate that a heatwave will persist across much of Italy through at least June 24. Temperatures of around 30-35 C (86-95 F) are expected across much of the country, with peaks of around 38-40 C (100-104) in central and southern Italy. The Italian Meteorological Service has warned that temperatures above 38 C (100 F) are possible in Basilicata, Puglia, Sardinia, and Sicily regions June 21-22 and in Calabria Region June 22. Thunderstorms are possible especially over northern Alpine regions in the coming days; however, conditions will likely remain hot and humid in these areas. The hot weather will likely exacerbate the situation in many northern and central areas that are experiencing severe flooding. Lazio Region declared a state of calamity June 20 due to the ongoing drought, with other regions including Emilia-Romagna, Lombardy, Piedmont, and Veneto expected to follow suit in the coming days. Some restrictions on water usage are ongoing in affected regions.
As of June 21, authorities have issued the following weather warnings across Italy:
Red heatwave warnings (the highest level on a three-tier scale): Basilicata and Puglia regions.
Orange heatwave warnings: Sardinia Region.
Yellow heatwave warnings: Emilia-Romagna, Marche, and Sicily regions.
Yellow thunderstorm warnings: Aosta Valley, Lombardy, and Piedmont regions.
Yellow strong wind warnings: Aosta Valley, Emilia-Romagna, and Piedmont regions.
Authorities will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.
Hazardous Conditions
The extended period of oppressive heat and dry conditions may produce ideal circumstances for wildfire growth throughout the region. Heatwaves also pose a threat to vulnerable groups - such as the elderly, children, pregnant women, and those with respiratory illnesses - due to the increased possibility of heat stroke or heat exhaustion during prolonged exposure to high temperatures. These health risks could also extend to relatively healthy individuals during significant heatwave events. In addition to significantly impacting athletes and those who work outdoors, high temperatures can cause problems for people using mass transit. The lack of air conditioning and cramped vehicles during rush hour may lead to some passengers being hospitalized for dehydration.
Transport and Utilities
Very high temperatures may warp rail tracks and force passenger and freight trains to operate at reduced speeds. Road surface damage is also possible, and overheated vehicles may worsen traffic problems in urban areas where congestion is already a problem. Commercial trucking disruptions might occur, as very high temperatures put more stress on engines, making tire blowouts more common. Major flight disruptions are unlikely at regional airports, but general aviation disruptions are possible, and some airfreight carriers could reduce cargo loads. High temperatures could lead to an increased demand for electricity, which might trigger localized brownouts or blackouts, exacerbating hazardous conditions when air conditioning is no longer possible.
Advice
Monitor local media for weather updates and related advisories. During heatwaves, remain indoors in air conditioning when possible. If outdoor activities are necessary, frequently rest in shaded areas; avoid activity during the hottest times of the day. Stay well-hydrated by drinking plenty of fluids. Avoid alcoholic beverages, which are dehydrating; drink water that is bottled or has been boiled. Wear loose-fitting, light-colored clothing. Cotton fabrics are more cooling than synthetics. Promptly seek medical attention if signs of heat exhaustion or heat stroke develop. Charge battery-powered devices in case prolonged electricity outages occur.
