Avoiding Cb associated with typhoons no problem if you have serviceable weather radar and know how to play with the tilt and gain controls. But don't even consider setting off towards a typhoon area over the ocean if the weather radar on your aircraft has a history of being dodgy/intermittent - especially a night flight.
I had the unfortunate experience of flying Taipei-Guam at night in a 737 where the radar mysteriously failed without warning although the screen showed green flecks such as one sees when radar reflects off the water below. We were in cloud when we ran straight into the storm clouds surrounding the typhoon eye. We swore the radar was working because there was no obvious sign of failure apart from it not showing the bloody great cloud that we hit. We got thrown around pretty badly for the next 5-10 minutes and frankly it was not an experience I would recommend to anyone.
The hard lesson I learned that night was always closely monitor your radar screen when near typhoon areas and watch for signs of radar unserviceability by continually checking the tilt control for appropriate radar returns. A nice green clean screen could mean a u/s radar.
