JUST how reliable is a lightning warning system (LWS)? This system, which is being installed in an increasing number of facilities in the country and around the world, claims to provide advance warning of oncoming lightning activity.
When the lightning activity is considered close enough to endanger the people within the facility, such as a golf course, a recreation ground or a large industrial complex, the LWS would trigger a siren to warn the people to take shelter immediately.
