So, assume 2000A, which is a number I have seen for the current. The direct power during the stroke is 2000 x 1000, or perhaps 2 megawatts, 2 megajoules per second. But, it is actually 60 microseconds long, so the energy is 0.00006 x 2 megajoules, or 120 joules per stroke, equal to 1 second of a 120W light bulb.

If there were 30 short flashes, that would add up to 0.00006 x 30 = 0,0018 sec, or almost 2 milliseconds. That would be 30 x 120, or 3600 joules total expended in a 5 foot section of stroke near you.. Youe would get the proportion of that according to how much angle you subtend vs 360 degrees around the stroke. Not necessarily a lot.

Even the entire 3.6 kJ is not a lot, kill you, burn you, sure. Vaporize you? Likely not.

This is highly dependent on conditions and assumptions. Choose your own according to lightning data and see how it comes out.........
