Hurricane Rita in the Gulf of Mexico on September 21, 2005. At this time, Rita's sustained winds were estimated at 140 mph, with gusts to 170 mph. A few hours later, Rita would be upgraded to a Category 5 hurricane with sustained winds of 165 mph.


Poleward migration of the latitude of tropical cyclone lifetime-maximum intensity away from the tropics. The linear trend is shown with its 95% two-sided confidence interval (shaded).
