what's the issue with riding in the rain? getting wet? cars can't see you? don't have rain gear? all of the above? do you have a plan for an all day storm, or is that not an issue?
Lightning strikes would be my first guess.
That and high winds and hail, plus the knowledge that it’ll be passing shortly.
I can and have ridden in other forms of rain like the UK tour three years back. Less pleasant, more dangerous.
