I just came back from a four-day trip in Hawaii. My sister was getting married down there. I noticed quite a few green federal modulators. I was also suprised to see a couple of rotting faded green thunderbolts in Honolulu. Unfortunately it was only when my father and I were driving because we had to take care of some wedding business. My questions about the green thunderbolts are, what are the similarities and differences between them and the yellow thunderbolts used for tornadoes?
