Wednesday September 6
Today Hurricane Irma set a record in the Atlantic basin maintaining winds of 185 mph for 24 hours. It beat Hurricane Allen from 1980 that was stronger at 190 mph, but held the speed over 180 mph for 18 hours that year. While at this speed, the eye passed within 50 miles north of San Juan, Puerto Rico. At this time, the hurricane force winds reached 50 miles form the center and the tropical storm force winds reached 185 miles away. The island was being battered.
Here we can see a 4 hour loop of Doppler Radar out of San Juan, PR. It was 4:36 PM to 8:46 PM AST. Below you can compare this to the satellite loop of various spectrums.
Infrared Satellite of various spectrums
Note, the first view is the infrared satellite (from space) with National Hurricane Center coloring of cloud tops. This enhancement shows height and intensity of convection. It may look like radar, but it is not showing rainfall intensity. Just the colder/higher cloud tops.
