What is it? Though it is unlikely to ever literally rain cats and dogs, heavy downpours involving fish, frogs and other small water animals have been reported for centuries. Though the scientific evidence remains sketchy, the most common explanation of the phenomenon is waterspouts – small tornadoes powerful enough to lift tiny animals from their watery homes before depositing them somewhere else.
Where can I see it? Lluvia de peces (the rain of fish) is such a regular occurrence in Honduras that the town of Yoro created a special annual festival in 1998 to celebrate the unusual phenomenon. The Festival de la Lluvia de Peces takes place every year in May or June when live fish are found flopping about on the town’s streets following a heavy storm.
