Heavy Rains Killing Fish
Heavy rains in Florida, combined with cloudy skies that block sunlight and warm temperatures have caused oxygen levels to drop in rivers. Reports of thousands of fish are being washed up in the wake of the storm. The heavy rain brings in a lot of run off that makes sunlight a scarce resource, a resource used by plants to make oxygen. Combine that with teh cloud coverage usually seen during hurricanes, and you got yourself very low dissolved oxygen levels.

It is amazing to hear that even fishes also suffer with heavy rains and it is also sad. when thinking of this i agree with you that oxygen levels will decrease during heavy rains.
