Trio of Caribbean Hurricanes early Sept 2017

Evolution of Hurricanes Katia, Irma and José, and of Tropical Storm 57. Note how:

• Katia developed late over Gulf of Mexico & stops shortly after head-on landfall
• Irma is the strongest having developed over warmer S Atlantic then Caribbean
• weakens to Category 3 on first Florida Keys landfall
• strengthens again over western Gulf of Mexico 
• immediately weakens at second Florida Coast landfall
• still Cat2 (not shown) then finally Cat1 before degrading
• José stays strong over water, strengthens briefly to Cat4-5 then swerves to W Atlantic
• Tropical Storm 57 never materialised into a possible and feared hurricane three-punch
