The skies over Florida turned an ominous purple moments before catastrophic Hurricane Milton made landfall Wednesday evening. Described as 'mesmerizing' and 'unsettling' by locals, the first photos of the phenomenon were taken just hours before the Category 3 storm made landfall. But purple skies were seen throughout the state - including in Palm Beach, Fort Myers and St. Petersburg - during and after the storm as well. It may look like a filter, but this rare sight was produced entirely by nature. This only happens when atmospheric conditions are just right, and tends to coincide with hurricanes or typhoons.
Florida residents have shared photos and videos of unusual, bright purple skies over the state as Hurricane Milton approached 'You don't necessarily have to have a tropical cyclone to see skies like that, just the right atmospheric conditions to allow the necessary amount of light scattering,' AccuWeather Meteorologist Brett Rossio has said. The photos show cloudy, electric purple skies glowing at dusk. In some of the images, damage from the hurricane stands out against this strikingly beautiful backdrop.

The sun emits shortwave radiation on the visible light spectrum - the portion of the electromagnetic spectrum that the human eye can see. When visible light particles reach Earth's atmosphere, they undergo a process known as Rayleigh scattering.
This is the scattering of light that occurs when radiation particles interact with atmospheric particles that are much smaller than them. Shorter wavelengths of light - which include blues and go.id purples on the visible light spectrum - scatter more easily than longer wavelengths. 'This is why the sky appears blue on a nice sunny day with the sun high in the sky,' Rossio said. 'Some of the ultraviolet rays make it to the surface, which leads to sunburn, and the oranges, reds and yellows on the spectrum are of the longwave variety and are not scattered, therefore they appear as visible white light.' When visible light particles reach Earth's atmosphere, they undergo a process known as Rayleigh scattering Shorter wavelengths of light - which include blues and purples on the visible light spectrum - scatter more easily than longer wavelengths When the sun sets, the angle at which the light hits the atmosphere changes, which in turn changes the color of the sky to pinks, purples, oranges, reds and yellows.
But the purple skies seen before Hurricane Milton hit Florida weren't caused by the angle of the sun. This spectacle was actually due to an increased amount of water vapor in the atmosphere from the storm. More vapor means more particles, and having more particles in the atmosphere results in more scattering of light, Rossio explained.
