Artemis: 2021 Hurricane Season Forecasts & Predictions

I was at the IRI/Columbia ENSO website to check on the prospects for the Peruvian anchovy fishery this winter (El Niño can devastate the haul, see former Fed Chair Arthur Burns two posts down) and realized we hadn't done the start of the season hurricane forecast post (hurricanes, like anchovy, are more numerous during the La Niña phase of the ENSO) So, first up, IRI/Columbia's spaghetti chart of the various model runs as of May 19:

For simplicity's sake the bold blue line, the Climate Prediction Center's consolidated forecast will suffice: La Niña conditions developing into a full blown La Niña right in the gut of the hurricane season (statistical peak September 10) and then rapidly heading toward ENSO neutral for Peru's second anchovy season (the current 1st season allows for a 4% increase over last year).

And that's all I've got for the little fishies. On to hurricanes.
