Keeping the radio on will alert you to any weather issues. Then you can decide whether to detour or stop. When carrying good paper maps, you should always be able to cope with weather and road closed, and find a detour.
I like your user name, and with an open mind you should be able to cope with everything you come across. Document everything, it will help you in future trips.
