Fascinating paper just published about the approaching 3I/ATLAS object in Space. Authors include Harvard astronomer Avi Loeb who says it could be technological, cloaking, and arrive on Earth around November/December 2025. lweb.cfa.harvard.edu/~loeb/HCL25.pdf

We confirmed an EF-1 tornado with 106 MPH wind gusts indicated in Teller County, 2 miles north-northeast of Divide, Colorado at 12:41PM on 6/17/2025. The exact track of the tornado still needs to be pieced together - we are awaiting drone footage to make that call. #COwx
