Today’s factismal: The most intense Atlantic hurricane ever recorded was Wilma, with a low pressure in the eye of just 882 mbar.
If you are a meteorologist, then 2005 is probably your favorite year. Over the course of the year, there were so many tropical storms that they ran out of names and had to resort to using Greek letters. Of the 28 storms that developed, a record high of 15 would go on to become hurricanes and seven of those would become major hurricanes. And none of those was more major than Wilma.
Wilma started as a tropical depression off of Jamaica on October 15. Two days later, she had become a tropical storm. By the 18th, she was a full-fledged hurricane and showing no signs of getting any weaker. Indeed, where most hurricanes are big, ungainly monsters with large eyewalls (which often indicates a weaker storm), Wilma had a fairly compact eyewall just two miles across (the smallest known) and peak winds of 185 mph! Those factors combined to give Wilma the lowest known pressure of any hurricane at just 882 mbar; to put that in perspective, remember that normal air pressure at sea level is 1013 mbar. In effect, the center of Wilma was at the same air pressure as Denver!
Naturally, a storm this intense caused lots of damage. Wilma killed at least 62 people (mostly through flooding and landslides) and caused $29 billion dollars in damage. Many of the deaths happened because Wilma’s path was unusually unpredictable; she changed directions several times, making it harder to know where she would hit. What the meteorologists needed was more observations in order to give better predictions. What they needed was people like the members of the Citizen Weather Observer Program who send in reports about severe weather (and the other kind, too) that is then used to make better predictions.
