Category 5
No, the above photo is not reversed; the storm is located in the southern hemisphere...
The first Category 5 storm of 2018 is Tropical Cyclone Marcus, which intensified to a low-end Cat 5 with 160 mph winds at 18Z (2 pm EDT) March 21, with a central pressure estimated at 921 mb. Marcus is located well offshore of the northwest coast of Australia, and is not expected to bring any direct impacts to land areas as it curves southwards, roughly parallel to the west coast of Australia. Marcus took advantage of very low wind shear and warm ocean temperatures near 30°C (86°F)--near average temperatures for this time of year. Satellite loops show a large storm with impressive organization, an eyewall with very cold cloud tops, and a 19-mile diameter eye. The storm is now headed into cooler waters, and has probably peaked in strength.
Our tropical storm "season" doesn't officially start here for a couple more months. In the meantime, the National Hurricane Center in Miami has a new Director.
