Blue lights over Angle Lake in Seatac, WA.

I was walking down the side of the hill on the public park side of Angle Lake, at about 23:35. There was fairly heavy rainfall and low clouds.

I was partway down the hill when there was a very bright flash of light above me. Several things made this very distinct, it was within the clouds shining outwards (so from my angle downwards) which made it obvious that it wasn't generated from the ground around me. The intensity made me think of lightning, except it was completely silent. And it was a vibrant electric blue in color, so distinct in hue that I almost fell over as I was shocked (I was completely sober).

It happened once more after about 1 1/2 minutes at which point I found myself wanting to leave the area quickly (which is fairly out of character).

I asked several locals about airport lights or static discharges in the area to which all responded in the negative, and were slightly puzzled by the question.
