Links about these unusual clouds appearing all over the world and this has been going on for sometime but like many I did not know about this until someone posted here on FR about the one that happend Feb 22 over Mexico city - will find that link to that thread and will post it or you can do a search with “cloud” as a key word and you will find those threads.

Thread about the Mexico city cloud of early this week with photo...
Do you have a friendship with Al Gore? You both are peddling the same crap.
Look further..these cloud formations have been explained.
Do a Google image & regular search for “hole punch clouds”, AKA “fallstreak clouds”.
Nothing all that mysterious nor “new” about them.
