The best way to avoid a lightning strike is to not be there or be prepared for it ahead of time. A simple way to detect an oncoming storm is to carry a small radio like this one:

or any small am radio. Lightning readily disrupts the AM carrier wave of any radio regardless if there is an active transmission on that frequency. Every lightning strike will generate a crackling burst of noise on the speaker or in your ear bud on any AM frequency if the storm is close. When you hear that regular crackling popping noise get to shelter now!
