I am new to gardening, and don't know what to do. I have yellow squash rotting on the plant. SEE PIC
Back Story: I am in Central Florida and have had drought conditions, followed by 7 solid days of rain. Around the 4th day I looked out to find my hills where the squash are planted covered by water, up into the plant. (This happened on and off for the next 3 days)

I am now noticing that most of my yellow squash, and some of my zucchini, is rotting, starting at the dying flower back into the veggie. I have been cutting off the rotten squash, SHOULD I BE DOING THIS?

I am noticing when I touch the flower part on the bad ones, the flower is full of water. (Could the water be what is ruining the veggie)

On my still healthy squash, should I remove the flower when it starts to dry out or does it fall off on it's own? I have noticed lots of bees landing on the beautiful squash flowers the past few mornings before the afternoon rains come and the flowers close up.

Also, do I remove the yellowing leaves at the base of the plant.
