If your Wx radar is actually transmitting.......
(1) There should be no danger to the occupants of the aircraft ahead, they should be well protected by the reflective structure.
(2) There should be no danger to you or the occupants of your own aircraft, you should be well protected by your own reflective structure.
(3) There could be considerable risk to your own radar, which is calibrated to receive less than 0.1% of the energy transmitted, but is now receiving probably 20 to 30% of it, and overloading the receiver. Perhaps your radar has a pre-set received signal threshold beyond which incoming energy is blocked, but it certainly WAS a problem on some aircraft at an earlier time.
