Aircraft; Weather
During our initial climbout between fixes; we experienced a WING ANTI-ICE LEAK master warning red CAS message. Note: we were in thunderstorm conditions within icing parameters. When issued a climb; finally after being level for several miles at 6;000 feet MSL; we went back to CLIMB POWER and First Officer initiated a climb at a rate of approximately 4;000 feet/minute to help get out of the weather. Shortly thereafter; we received the red message. Pilot in Command elected to level off at approximately 12;000 feet MSL; where the heavy rain still existed. A divert was executed through Departure. We were vectored for Converging ILS X RWY XX at divert airport. This report is designed to draw attention to a problem that keeps happening to the Challenger 350S. The same experience happened [on a prior date] which resulted in a diversion. Other crews are talking about the same issue happening to them. Hopefully this will help get more attention to this situation.
