Narrative:
On taxi out; we observed the le flap transit light illuminate with different slat lights come on; number 8 was the most frequent. I called dispatch/maintenance control; who instructed me to extend them all the way out and retract them; which I did. We had all good indications; so maintenance said we were good to go. On takeoff roll at 80 knots; we got a takeoff warning horn and a le flaps transit light. I rejected the takeoff and returned to the gate after the first officer calculated the brake cooling data; which was said we were good to return to the gate. Other considerations in the decision were thunderstorms all the way to our destination.the mechanic said there was water in the control box that was causing a short; which lead to the malfunction.
