Because of the water temps going up and down I would be ready for plan “B”. If the flats aren’t doing well, I would head to the mouths of the canals. Have some different bait. Shrimp, Fiddlers, White bait, whatever you can get.
There are no solid rules with the way the water is changing right now. One day or morning it is all shrimp. Then bang, it’s changed and they are eating white bait. Or maybe fish in the morning and shrimp later. If the weather stays steady for a while then you can get handle on what’s going on bait wise.
But for now, be ready to switch.
