Lightning-prediction system

Lightning protection systems are often installed in outdoor areas which are often congested with people, lack sufficient shelter, and are difficult to evacuate quickly (such as water parks, college campuses, and large swimming pool or athletic field complexes).

[citation needed] The detection equipment is designed to constantly survey atmospheric electrical activity and potential for lightning occurrence via radar and other methods.

[citation needed] By detecting thunderstorm electrical fields, a track can be predicted to allow warnings as early as 30 minutes before lightning strikes the protected area.

[citation needed] The system is synchronized with the U.S. Coast Guard LORAN navigation network, and includes various features which permit a more accurate analysis of lightning position.

[citation needed] While some systems require manual remote activation of the siren from the central monitoring facility, others work automatically.
