Free tools & data to predict hurricanes

Four weeks ago I blogged here about the availability of open data, posting it on the open web and its potential social impact. Two weeks ago I blogged here too about tracking three hurricanes in the Caribbean via the brilliant but closed earth.nullschool.net. In between I compared & contrasted open & closed regimes on my Medium channel... and that 2½ yrs after a previous blog here on same!

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
