Sounds like the kind of crap Isaac Cline took for Galveston. Weather is not an exact science, and it seems to me they ended up getting the track pretty much right.
Cline evidently misrepresented his role at Galveston...for instance, no eyewitnesses could be found to corroborate his claim of a Paul Rever-like ride up and down the beach warning people of the approaching storm. He and his brother--also a weatherman--had a falling out in the wake of the hurricane and never spoke to each other again.
None of which has anything to do with Santorum's flap. Just a historical footnote.
