What is Thor Guard TG 360 ?

Commons & Beaches TG360 Link

Thor Guard TG 360 prediction technology samples the atmosphere over 170,000 times per second and the new prediction based lightning detection provides instantaneous distance and direction to lightning strikes in the immediate area. The weather data interface provides:

  • Force speed
  • Wind speed and direction
  • Temperature, Humidity, Dew Point and Heat Index evapotranspiration rates
  • TH has also included GENS, their new Emergency Notification System. Over time, the Tornado Prediction System will evolve as additional data is provided by local storms and neighboring TG 360 systems.

How Do I Monitor Thor Guard? 

The ability for members to make informed decisions by checking Thor Guard is made available through these various channels:

  1. Thor Guard monitors at Foundation buildings and all tram stations (with the exception of Tram Station #1).
  2. Pelican Bay mobile app under the “Weather” tab.
  3. PelicanBay.org under Beach Conditions and the Restaurants pages.
  4. Conditions and the Restaurants pages.

Thor Guard monitors are fixed at all tram stations, displaying a radar map and accompanying alert message that broadcasts a range of messages from ALL CLEAR to a RED ALERT. Also, members are encouraged to download the Pelican Bay mobile app. With these tools, members can determine their options for proceeding to the beach.

The Various Thor Guard Statuses and Their Meanings:

All Clear – Force 0.0 – 1.0

  • What it means:
    • There is little to no significant energy, energy change or lightning threat present locally.
    • When the system enters ALL CLEAR, three long blasts for 5 seconds each will go off.
  • What to do:
    • Enjoy your time on the berm, at the beach and restaurants.

Caution – Force 1.0 – 2.0 

  • What it means:
    • The possibility of lightning is increasing due to energy changing in the local atmosphere.
  • What will happen:
    • Staff will advise members we are in a CAUTION and a WARNING could be imminent.
    • When at the beach or in the water, the Foundation staff will raise a yellow caution pennant to advise that Thor Guard has gone into CAUTION mode.
  • What to do:
    • Make the necessary preparations in case the system goes into a WARNING or RED ALERT.

Warning – Force 2.0 – 3.0

  • What it means:
    • The likelihood of lightning continues to increase as the local atmospheric energy is spiking.
  • What will happen:
    • Staff will advise members we are in a WARNING and a RED ALERT could be imminent.
  • What to do:
    • Take precautions and make decisions to plan accordingly on whether you go to the beach or restaurants at this time.

Red Alert – 3.0 +

  • What it means:
    • The probability of lightning is now high enough in the local atmosphere that lightning is predicted and/or will be detected soon.
    • One long blast for 15 seconds will go off when the system is in RED ALERT.
  • What will happen:
    • All tram and beach operations will shut down during the RED ALERT and will not resume operations until the ALL CLEAR has sounded.
  • What to do:
    • Available trams have 13 minutes from the initiation of the RED ALERT to transport you to Tram Station #4 (Commons) or Tram Station #8 (North Lot) and proceed to your vehicle. If you are at the beach, you should immediately pack-up and seek a safe shelter.  If you remain at the restaurant, you should seek safe shelter.

Heat Warning Levels: 

No Heat Warning

  • Heat Index Below 96 deg F

Heat Warning 1

  • Heat Index 96 – 104 deg F

Heat Warning 2

  • Heat Index Over 104 deg F


For the safety of members and employees, please note that staff cannot assist in any way during a RED ALERT. If you choose to walk, it is at your own discretion.
