What is the lowest atmospheric pressure ever recorded in an Atlantic hurricane?

What is the lowest atmospheric pressure ever recorded in an Atlantic hurricane? The record low is 882 millibars, measured in Hurricane Wilma in 2005.

Wilma reached this pressure over the western Caribbean Sea on October 19, 2005, during an extraordinary period of rapid intensification. In roughly 30 hours, its central pressure plunged from 982 to 882 millibars, while its maximum sustained winds rose to about 185 mph. That pressure remains the Atlantic basin record for the lowest central pressure in a hurricane.

A Hurricane Hunter dropsonde directly measured 884 millibars inside Wilma’s eye. Because the instrument did not reach the calm center of the eye, meteorologists estimated the true minimum pressure at 882 millibars. This is why some accounts mention both numbers, but 882 millibars is the official record value.

Wilma’s tiny, pinhole eye measured approximately 2.3 miles across at peak intensity. The previous Atlantic pressure record was 888 millibars, set by Hurricane Gilbert in 1988. Lower pressure generally indicates a more intense tropical cyclone, but it does not by itself predict storm size, rainfall, storm surge, or total damage.
