Overview
- The national Civil Protection issued an adverse-weather advisory for Wednesday with an orange alert for Liguria di Levante and yellow alerts across many northern and central regions.
- A low-pressure system of Atlantic origin moved into the Mediterranean and fed strong atmospheric instability that drove storms from the North down into the Centre-South.
- The deterioration that began on Tuesday continued overnight and produced a heavy 'bomba d'acqua' in Rome around 7 a.m., causing thunder, lightning and commuter disruptions.
- Authorities warned of specific hazards including heavy showers, strong wind gusts, local hail and intense lightning, with localized flooding and fallen trees already reported in northern areas.
- Forecasts say modest high pressure will partly stabilize conditions but short-lived, isolated storms remain likely in mountainous and inland zones, so regional monitoring and local precautions stay necessary.
