This storm is a monster.  It strengthened from a pretty usual category 1 hurricane to the most powerful hurricane the planet has ever seen in less than a day.  This strengthening was all due to the warmer-than-usual pacific waters under the influence of el nino. Luckily the storm has weakened since making landfall and is down to a tropical depression (less than a category 1), but it still highlights the fact that warmer oceans and a shifting climate are bringing more extreme weather events our way every year.
