I agree with Clark. The pics I have of Camille are very grainy. This storm is too far west for a MS landfall. Try checking the NOAA NESDIS library of satellite shots. I will take you a while but you may just find it. The storm looks poised to make landfall around Corpus Christi/ Galveston Bay area. Judging from the clouds in the Pacific and the lack of clouds in the Midwest, I would say maybe a September storm. Cool air over the Pac. Ocean. Then again it could be an early June storm, but there just isn't enough convection over the Midwest to go with that.
There was a CAT 2 or 3 in TX in the early 70's. Allen comes to mind.
