California Floods, Japan Snow: Extreme Weather Strikes

California is on alert with evacuation warnings issued as "atmospheric rivers" unleash heavy rains, posing risks of flooding and landslides along the western coast. These moisture-laden air currents, while vital for reservoirs, can bring destructive downpours.

In contrast, Japan's northern islands, Honshu and Hokkaido, have been blanketed by significant early-season snowfall, with one town recording over a meter, breaking historical records for this time of year. This extreme weather event stands in stark contrast to other regions.

Meanwhile, Australia endured severe thunderstorms causing widespread power outages, hail, and strong winds, alongside lightning-triggered bushfires. Italy tragically experienced two deaths from mudslides due to extreme rainfall, with one town evacuated as a river overflowed its banks.
