An incredible cloud formation has appeared in the skies over Split as thunderstorms rolled across Croatia on July 26, 2017.
The huge disc-shaped cloud resembles a mushroom cloud or alien spaceship and announces the next big storm rolling in.
But rest assured, good people of Croatia, this is actually a perfect example of a thunderstorm anvil, also known as a cumulonimbus.
The spectacular formation is giving Split residents a reprieve from the hot weather, dropping the temperature below 35 °C.
The cumulonimbus clouds brought rain and cooler temperatures to the the largest city of the region of Dalmatia in Croatia.
Croatia is currently swept by unstable weather as an anomalous hailstorm hit Istria, on the Adriatic Sea today.
It’s not unusual to see these at this time of year, but some of the pictures we’re seeing show no other clouds, that’s why it might be a bit special.
You can see the gigantic formation evolving from a towering cumulus clouds into cumulonimbus, the actual thunderstorm cloud.
