Hurricane Betsy (1965)

Surface analysis for Hurricane Betsy on September 5, 1965

"About the only consolation you have is when it gets level with your latitude, the chances are pretty slim it will turn back" - Forecaster Raymond Kraft

Hurricane Betsy was an erratic hurricane with movement taking her nearly up 30 deg north then abruptly turning south around the southern tip of Florida. Key Largo was hit directly, then the New Orleans area would be next. The death toll reached 75 & when all was said & done, both Florida & Louisiana were very lucky as things could have been much worse. At landfall in South Florida a yacht measured a 6 ft tide in the Miami River. A low pressure barometer graph of that is seen here
