After careful review, a committee of the World Meteorological Organization has determined that Hurricane Wilma set a 24-hour record for rainfall in the Western Hemisphere back in 2005.
A few months ago, the committee reported in the WMO Bulletin that it had verified that 64.33 inches of rain fell from 9:30 a.m. Oct. 21 to 9:30 a.m. Oct 22 on Isla Mujeres, off the east coast of Mexico.
Yes, that would close to 5½ feet of rain, or the water equivalent of more than 50 feet of snow.
The rain was measured by an automated gauge, and the committee took some pains to determine that it was, indeed, accurate.
