Rare octuplet waterspouts form over the Baltic Sea between Poland and Denmark

"A rare waterspout outbreak occurred over the Baltic Sea on August 21, 2025, producing at least 12 waterspouts off the coast of Poland and 8 off Denmark, including one sighting of eight simultaneous funnels.
They form when warm surface waters interact with cooler air masses aloft, creating strong vertical instability, low-level wind shear, and convergence zones conducive to vortex formation." W
