Hurricane Rosa (2018) [SEP] Meteorological history
The NHC remarked that Rosa's structure was well developed at the middle levels of the troposphere, with distinct rainbands wrapped around the southern semicircle of the cyclone. The hurricane leveled in intensity for eighteen hours before proceeding into another phase of rapid intensification; it reached major hurricane status at 18:00 UTC on September 27, peaking in intensity with maximum sustained winds of 150 mph (240 km/h) and a minimum central pressure of 936 mbar (27.64 inHg). This made Rosa the seventh Category4 hurricane of the year's season. After Rosa reached its peak, the hurricane's eyewall – an inner ring of clouds around the eye – began to warm considerably, signaling the start of an eyewall replacement cycle.
