If it was so dangerous, no one would use an umbrella during a storm. However, talking about the potential lightning strike thanks to an umbrella, it is as probable as accurately determining where the lightning will strike.

The most vulnerable to lightning strikes are tall objects - towers, spires, antennas, tops of houses, very tall trees, mountain peaks, power lines, but there are also cases of strikes on smaller stationary and moving objects.

An alternative to an umbrella is a raincoat.

Fun fact: Roy Sullivan - a man who survived being struck by lightning seven times - was listed in the Guinness Book of World Records. He died on September 28, 1983. The cause of death was probably suicide.
