- The Lightning Proximity Alert allows you to set 3 levels of alerting.
- Red is always the “highest level”, in the case of lightning, the inner most ring.
- Orange is the middle level.
- Yellow is the farthest out.
- Defaults for each level is set by the user.
- As the defined threshold (status) levels are breached a status is applied to that location. Notifications can also be sent as this status level is applied.
- If a strike is detected in a higher level ring. The status is changed to the higher level.
- To downgrade or clear there must be 30 minutes with no strikes in that range.
- An ALL Clear is only issued when there has been no strikes in any defined rings.
Below is an example> For these scenarios assume the following:
- A ring is 5 miles labeled as “Red”
- B is 10 miles labeled as “Orange“
- C is 20 miles labeled as “Yellow“
- Embargo period is 30min for all thresholds.
Example
- 3:00 pm – Strike 7 miles NW of Asset
- Orange Status active and notification sent
- 3:10 pm – Strike 4.5 miles NNW of Asset
- Red Status is active and notification sent
- 3:10 – 3:30 pm – Strikes continue in Red zone
- No change, status is still Red
- 4:00 pm – No strikes since 3:30 pm, strike at 3:45 pm in Orange zone
- Downgrade to Orange and notification is sent
- 4:00 – 4:15 pm – Strikes continue in Orange zone
- No change, status is still Orange
- 4:45 pm – No strikes since 4:15 pm, strike at 4:30 pm in Yellow zone
- Downgrade to Yellow and notification is sent
- 5:00 pm – No strikes since 4:30
- All Clear is issued.
