Our thoughts and prayers are with all three divers. Apparently up/downwellings are common in and around Cozumel - Upwellings and Downwellings: Undercurrent 02/2001
Quote from Undercurrent.org:
"One final note: Cozumel is notorious for its vertical currents. While the diving there is exciting, it can often be intimidating for beginners or those who lack confidence in their skills. Reader Pat Wikstrom ( Warne, N.C.), in Cozumel last year, wrote: On a dive at La Francesca Wall, we jumped into a ripping current that quickly broke our group into three separate pieces. Weird downcurrents caused my wife and me to abort the dive. Nevertheless, the poor DM chased the other two sections of our party all over the wall, brought up half the others after ten minutes, and went back down to find the last few folks and get them back safely. He really earned his tip that day.
We've dove there for years with no issue. Our best to Heath, Opal and Gabi.
