A waterspout is one of those things that can ruin a day at the beach in an instant. Beachgoers in Brazil were content to watch the spout from the shore this weekend, until it frighteningly ran aground, prompting vacationers to scatter.
Waterspouts like these sometimes develop just offshore under cumulus clouds, though it doesn’t necessarily need to be stormy. Often they can occur under an otherwise uneventful deck of stratus. In this case it does look like there were some stormy clouds moving through, which helped to spin up the spout.
