Tourists and residents in the popular Romanian seaside resort Mamaia had the chance to photograph an impressive cloud formation on Tuesday, July 7, amid a severe weather warning. This wave-like cloud that seems to fall over the Mamaia beach is known as a Shelf cloud, according to local Facebook page Furtuni Romania, which tracks severe weather phenomena across the country.

Shelf clouds are low, horizontal, wedge-shaped arcus clouds, attached to the base of a parent cloud, which is usually a thunderstorm cumulonimbus.
