or could be a daily thing...the color scale is in degrees Celsius. The criticla temp for hurricane development is you need waters to be at least 26 degrees C.

GOES sateliites measuer SST as do other's with IR sensors, but clouds get in the way. Now SST charts are produced using microwave snesors on the military SSMI, and the civilian AMSU sensors which are aboard the polar orbiting satellites. Resolution for microwave not as good, but like I said - can "see" through clouds.
