LIGHNING WARNING SYSTEM



The Club has a lightning detection device to help us determine when it is dangerous to be on the golf course. Lightning is a severe hazard that must be viewed seriously. Players must immediately stop play and seek shelter any time they believe lightning threatens them, even if a signal has not been sounded.
  • The signal for suspension of play will be one prolonged blast of the horn.
  • The main detection unit is on the Clubhouse roof, with a second horn located by the Greens Maintenance Building.
  • All players must immediately leave the golf course and return to the Clubhouse.
  • The system will automatically signal resumption of play by providing three consecutive horn blasts when it is safe to return.
  • If caught in the middle of a lightning storm, members and guests may seek shelter at any of the following lightning rod protected areas; Times Square Gazebo, Gazebo being #18, rain shelter #12, washroom #15. Please do not go to the Greens Maintenance Building.
Additional Safety Recommendations
  • Keep a safe distance from tall objects, such as trees, hilltops, and telephone poles.
  • Avoid projecting above the surrounding landscape. Seek shelter in low lying areas such as valleys, ditches and depressions.
  • Stay away from water. Lightning can strike the water and travel some distance from its point of contact.
  • Stay away from objects that conduct electricity, such as tractors, golf carts, golf clubs, metal fences and lawnmowers.
  • Avoid being the highest point in an open area. Swinging a golf club or holding an umbrella can make you the tallest object and a target for lightning.
  • In a forest, seek shelter in a low-lying area under a thick growth of small trees or bushes.
  • Keep alert for flash floods, sometimes caused by heavy rainfall, if seeking shelter in a ditch or low lying area.
  • If caught in a level field far from shelter and you feel your hair stand on end, lightning may be about to hit you. Kneel on the ground immediately, with feet together, place your hands on your knees and bend forward. Don't lie flat.
  • If you are in a group in the open, spread out, keeping people several yards apart.
 

THOR GUARD predicts the probability of a lightning hazard in an area up to 25 square miles. More importantly, it also provides a specific reading of the risk in your immediate area. Here are some important facts about the Thor Guard system:
  • How Does Lightning "Prediction" Differ From Lightning "Detection? Lightning "detection" systems detect the electromagnetic signatures that are the by-product of actual lightning strikes. Lightning "prediction" senses and evaluates the shifts and changes in the electrostatic field that precede the occurrence of an actual lightning strike. This is the reason why our unique lightning prediction technology has always been able to provide warning before the first strike. According to a leading lightning detection manufacture's specification sheet, they need three strikes within 10 miles before they achieve peak operation. What if the first strike is right on top of you?
 
  • Is There A Minimum Acceptable Range For How Close A Lightning Strike Has Occured Before Shutting Down Operations?This is not an issue when using a THOR GUARD system because we are predicting strike probabilities for your immediate area of concern and updating the data 50 times a second. For lightning detection systems, however, the choice of the correct range is critical. The most recent data from a 1998 study by Messrs. Holle & Lopez (Severe Storm Center) would indicate that the minimum acceptable range from the last strike should be no less than 6-8 miles. This obviously would indicate that waiting for lightning to reach the previous standard of a 0-5 mile range, is dangerous. The new data also challenges the popular "Flash to Bang" theory because lightning can rarely be seen and/or thunder heard, as far away as 6-8 miles.
 
  • What Is The Difference Between Lightning "Protection" And Lightning "Warning" Devices? If you should hear that the THOR GUARD product is not a "protection" device or system, that would be correct. We offer lightning "warning" systems, not "protection" systems. According to the "Lightning Protection Institute" a lightning "protection" device provides actual protection against a strike. In this category are surge suppressors, lightning rods, grounding systems, large buildings, etc. THOR GUARD WARNS PEOPLE BEFORE A STRIKE WILL HIT TO GO AND SEEK "PROTECTION"! Any company that represents that a lightning detector or horn warning system is lightning "protection" does not understand the facts.
 
  • Does Your System Shut Down Due To Cloud To Cloud Discharges Like Detection Systems Or Is It Prone To Giving False Alerts ("False Positives")? No, our system does not shut down due to cloud to cloud discharges. Because we monitor the electrostatic atmosphere and compare all readings to a finite database, we seldom issue false warnings that result in our horns being activated. Do you think that all the professional golf tours and other clients would continue to utilize our products after-years of experience if we gave false-readings?
 
  • How Much Advance Warning Can I Expect From A THOR GUARD Lightning Prediction To Find Appropriate Shelter? The THOR GUARD system has been designed to offer various sensitivity levels in order to satisfy a diverse range of client needs and geophysical locations. In a typical user-selected range (12 mile/2 miles) the system would provide 8 to 20 minutes advance warning. It is important to note that lightning does not need to be visible before a warning is given. Our unique "Field Collapse Counter" is the most accurate lightning detection method in existence today and will respond to subtle migrations of potentially dangerous energy.
 
  • What Is The Audibility Range Of One Voice Of THOR HORN Warning Remote? The normal range of one "horn cluster" (six air-horns) is 700-800 yards, in a 360° pattern. Typography, tree density, air moisture content and ambient noise are all factors that will affect performance! For example: A normal 18-hole golf layout will need (1) Base Transmitter/Horn Cluster and (2) Remote Receiver/Horn Cluster locations.
