Key turns and........ nothing!

[khunsa]

well i took my car for a drive today at about 4pm and it started good (like normal) and came home, then at 8pm after a heap of rain, thunder and lightning, i was gonna go to the shop, and hoped in the car and when i turn the key, nothing happens, only all the engine check lights come on (power steering, abs, battery, ect) Wot could it be? Help would be greatly appreciated. Oh, the make/model : 89 rs legacy.
