Meteorological Question? Can heavy rain occur without the presence of big red blogs on the radar?
The radar indicates a cloud’s rainfall intensity by displaying colors contrasted against a black background. Areas of heaviest rainfall appear in red, the next level of rainfall in amber, and the least rainfall in green.
I have had ATC ask me if I wanted a vector for weather avoidance, the path looked clear on radar. ……the path was not clear so I am not 100% convinced the radar is always right!
