When you open up one of the sites, there is a lot of information displayed:
The little red bar in the center of the black line displays the type of electrical charge being sensed at that site.
- If the bar moves to the left, it’s mostly negative charges.
+ If to the right, it’s mostly positive charges.
LHL—Lightning Hazard Level
The percentage chance of lightning / amount of energy within 15 miles of this sensor
The percentage chance of lightning / amount of energy change within 2.5 miles of this sensor
The time since the last discharge/lightning strike. It will count down from 10 minutes, and at zero, an ALL Clear will be signaled (three 5 second blasts of the warning horn)
FCC-Field Collapse Count
How many lightning strikes (field discharges) within 15 miles since the last time the system went into alert status (the point when it last predicted a strike within 2.5 miles within the next 10-15 minutes)
