  • At least 4 dead as Storm Hans batters Italy and France

    At least 4 people died in Italy and France as Storm Hans battered the countries with heavy rains, floods, and snow since Wednesday, April 16, 2025. Many areas in lowland Italy have received over 300–500 mm (12–20 inches) of rainfall, triggering landslides and causing rivers to swell, while heavy snow in the Alps has caused avalanches in France.

  • Polar vortex collapse to influence spring weather across U.S. and Canada

    Large-scale pressure changes following a strong sudden stratospheric warming event in mid-March 2025, which caused the collapse of the polar vortex, are expected to drive spring weather patterns across Canada and the United States into May. Northerly winds are expected to bring colder air into parts of North America, while high-pressure zones may lead to warmer conditions in the central U.S. and southern Canada. The shifts in weather patterns are consistent with the typical effects observed following a polar vortex disruption, where the jet stream becomes more erratic, leading to unusual temperature distributions and weather events.
