Yes, if you mean "... spark at the distributor-end of coil wire".
But, a weak spark (output voltage) combined with a wide gap and old wires
might make the difference.

Had almost the same thing happen to a '79 Honda Accord. The third-party
rotor couldn't handle the high-voltage, so, in short time, the coil voltage
sparked straight through the rotor to the top of the distributor shaft.
Not moisture dependent, though.
