Rare weather phenomenon grips Portugal beach during heatwave
This is the moment a rare phenomenon was spotted at a beach in Portugal, as the country faces a heatwave with highs of 42C. Beachgoers on Sunday (29 June) were shocked when they saw a 'roll cloud' coming out of the ocean and heading towards the shore. The dense tsunami-like cloud occurs when hot and cold air masses collide, forming a thick cloud that condenses into a curved-shape. Climate expert Mário Marques said it is not the first time Portugal has experienced a roll cloud, but is more common to witness the phenomenon in somewhere like Australia, where cold air from Tasmania collides with hot air on the mainland.
