[PT-South swell]
The concept of the often mis-quoted Butterfly Effect is simply how minimal changes in input can result in wildly different outputs, i.e. forecating a swell 16 days in advance can throw up some hugely different senarios. However when a massive south swell event like this one (which has had the forecasting world fixated for the past week) gets moving all you have to worry about calling is how big will it get? Well, Central America and Mexico are currently looking about as good as it gets. Waves faces three to four times overhead are already there and will continue throughout the day. Despite suffering slight decay California will be overhead. Heading north a swell like this will esentially travel until it hits land so call in sick and dig out your boards.
