NEXRAD is the composite radar feed you see on your phone or on a computer. Some years ago the Sirius satellite radio company started providing a NEXRAD feed for boats and aircraft. Normally absent onboard weather radar there is no easy way for a pilot to know exactly where a storm is, so prudent aviators give them a wide berth. When NEXRAD came out, some pilots tried to use it tactically like onboard radar and fly between the storms. They didn’t realize it was not real time and the “space between the storms” they were flying through on their display was now the middle of the storm.
