Go to Autozone, get the codes read (FREE), and post the exact codes back here. Not what they tell you what they mean, we need the exact codes.

It could just be moisture on the sensor.

Water in your COPS could cause the CEL to come on.

Huh?

Your ignition system took a bath - Their allergic to water. You won't really know the extent of damage until it's cleaned up and dried out along with every other connector that's been exposed to water.

Let me rephrase - you need to find an OBDII code reader and read the codes. Trying to diagnose a CEL without one is almost impossible, you can't paperclip the socket and count light flashes any more.
