Italy sets new European 12-hour rainfall record

A severe storm stalled over NW Italy on October 4, 2021, dumping record-breaking rain and causing floods and landslides. In addition, the storm produced more than half a million lightning strikes within 48 hours.
The day started with 496 mm (19.5 inches) of rain in just 6 hours registered in Cairo Montenotte, Province of Savona, Liguria, breaking the country's 6-hour rainfall record of 472 mm (18.6 inches) set in 2011.1
In just 12 hours, the same storm system dropped 740.6 mm (29.1 inches) of rain in Rossiglione, 13 km (22 miles) E of Cairo Montenotte, in the Province of Genova, Liguria, setting a new European 12-hour rainfall record.
That's more than half of the average rainfall the region gets in a year — 1 270 mm (50 inches).
Italy… a new European record.
A whopping 740.6mm (29.2 inches) of rain in just 12 hours!
Italy set a new national record for rainfall in 6-hours and then went on to break the European record for 12-hour totals.

Agenzia Regionale Protezione Ambiente Ligure (ARPAL) reported 1-hour rainfall totals of 145.2 mm (5.7 inches) in Cairo Montenotte, 178.2 mm (7 inches) in Urbe and 181 mm (7.1 inches) in Vicomorasso – a new national record. Furthermore, figures from ARPAL show the station at Rossiglione recorded more than 900 mm (35.4 inches) of rain in 24 hours.2
All that rain caused numerous rivers to overflow and produced traffic-disrupting landslides.
While authorities said they responded to many calls for help, including rescue operations, there are no reports of casualties.

New weather phenomenon records set are a nearly everyday normal. Celebration? Are these notorious events wanted in the slightest manner? And how did humanity end up in the gloomy rain-saturated and on the other hand a fire forced disaster cycles? How to switch off it?
We would like to share a soon-to-be important video that would greatly impact Humanity in a positive way and save many lives. No miracles, all is science.
