DISCUSSION: Over the past 24 to 48 hours, there was a very impressive example of tropical cyclone intensification on display across the open waters of the Eastern Pacific Ocean. This recent tropical cyclone intensification was characterized by Tropical Storm Fernanda intensifying to hurricane strength by Thursday evening. Furthermore, within the next 30 hours following that time, Hurricane Fernanda underwent a period of fairly rapid intensification as Hurricane Fernanda went from a Category 1 to a Category 4 hurricane. As it stands right now, Hurricane Fernanda is a Category 4 hurricane with maximum sustained winds of 145 MPH with a minimum central pressure of 947 mb. Hence, this is a very intense and dangerous storm for any and all boats/ships which are trying to pass through that part of the Eastern Pacific Ocean. In looking at the following couple of days, the oceanic and atmospheric environments which Fernanda will be traversing will remain quite conducive for this tropical cyclone to either further intensify or maintain its current intensity. This will primarily be due to a combination of warm sea-surface temperatures and relatively low vertical wind shear which are ideal for periods of tropical cyclone intensification.
