“The photo above shows an eye-popping complex of waterspouts I observed over the Adriatic Sea on a boat trip to Brindisi, Italy. As we departed, the weather was very summer like — some humidity, hot and sunny. Cumuliform clouds developed during our excursion, but the weather didn’t appear threatening. In fact, the atmospheric pressure was stable at 1024 millibars.
Suddenly, we saw a line of funnel clouds straight in front of our boat! The photo shows the most recently formed waterspout in the foreground; the oldest spout, in the background, would disappear in a few seconds. Our boat actually passed through the scary funnels. The spouts were spaced about 1/3 nautical mile from each other. I asked the boat’s captain if he thought cruising past the spouts would be dangerous, but apparently, he wasn’t bothered much by their proximity.
