Best open the hood and let that puppy dry out for a day....the waater can cause the missfire due to spark wire leak current...all wire leak some...older ones more than new. If the light comes back on after you let it dry...it will take more investigation later.
you most likely have water shorting out the ign system. you can drive and hope it goes away or you can get compressed air and blow everything under the hood dry and see if that helps
