You're of Nam, so with lots of tropical experience you know as well as anybody that flying through red is often times not an issue. All red means is there is lots of water
Had a captain who thought like you, flying into BRU large red circle right in our way "ahh there is not much turbulence in this region, that is just rain density" BAM, satic discharge that shocked all our senses............ Stay out of the rain if you have the fuel to burn.
