| Flash vs Stroke | |
| Each stroke represents a single detection from the lightning detection hardware. But lightning actually occurs as flashes. Each flash is what we think of when we see a bolt of lightning. | |
| Storm Analysis | |
| Below is some examples of what storms will be identified as: | |
 |
|
| When a storm has been filled in with colour, it means there is a preponderance of +ve strokes, this means the storm has the potential to become more severe. Lightning is very likely in area inside of the marked storm. |
|
 |
|
|
When close flashes are detected and are more grouped together the storm detected will be in a round shape. This means that lightning is extremely likely in the immediate area. |
|
|
Also if the Lightning Map appears to have a Yellow border, it signifies there is Yellow Alert in place. If the border is Red then it signifies there is a Red Alert in place. |
|
|
Red Alerts occur when the stroke count exceeds 250 or when a storm moves inside the Red range ring. When this happens a storm is occurring nearby. This poses a very High risk of lightning occurring in the area.If you are inside the red range ring and a red alert has been issued with a storm inside the ring: 1. Disconnect all electrical appliances. 2 .DO NOT take a shower or bath! 3. Move inside immediately if outside. 4. End any active phone calls. The above instructions will help minimize the risk of getting struck. |
|
|
Yellow Alerts occur when a storm is occurring in your region or is breaching 150 strokes. If a Yellow Alert has been issued and you live inside the red or yellow range ring: Keep an eye on the storm and periodically check where its heading. If you start to notice the storm is getting closer and has a colour representing stronger thunderstorms: It is recommended that you: 1. Clear and check your Gutters 2. Secure any loose objects outside. 3. Move any car residing outside into shelter. 4. Check local Doppler Radar and your local Meteorological Organization/Department. 5. If in the U.S turn on your NOAA Radio. |
