Very isolated but hugely vertically developed cloud system due to a small cold pocket of air over Malta in the upper reaches of the atmosphere at 500mb height (refer to third thumbnail). This created instability over the area. A thin moist-air layer at an altitude of 9.5km made the anvil quite thick when the air finally reached this stable layer. The first thumbnail shows another cumulonimbus cloud (this time `Cb Incus` due to its characteristic anvil-like upper section) that developed to the right of the main photo. Very little wind shear was present over the area.
