Thermo nuclear explosion?

This is not thermo nuclear explosion but growing cumulonimbus cloud at sunset, which penetrated through high clouds, seen from safe distance on Velebit mountain. It is dumping rain and most likely hail somewhere in Lika region, which is placed behind Velebit (continental side). Such afternoon or evening storms are common in June in Lika but they rarely develop above or reach Velebit. Photo: Aleksandar Gospic
