*Note that in the semi-arbitrary method I used to assign storm severity:
// Lightning Alert Variables and Constants
int alertLevel = 0;  //0. no discernable activity
int alert1 = 255;   //1. light
int alert2 = 511;   //2. moderate
int alert3 = 1023;   //3. heavy
int alert4 = 2047;   //4. hide (severe)

which trigger the following email warnings:

Alert Level 0.
There are no lightning storm alerts at this time.

Alert Level 1.
Some lightning activity is indicated in the vicinity of the summit of Mauna Kea.

Alert Level 2.
Moderate lightning activity is indicated at or near the summit of Mauna Kea.
Another alert will be sent when conditions change.

Alert Level 3.
Be advised, there is now heavy lightning activity at the summit of Mauna Kea.
Take necessary precautions.

Alert Level 4.
Warning! Severe lightning activity is currently taking place at the summit.

(Note: These storm severity parameters will most likely be updated as the system is refined.)
