it would be devastating. To preface, much of the area has minor but disruptive flooding with heavy summer t-storms. That much rain has no place to go. The city/metro has extremely dense vegetation and tree cover (one research outfit rated Tampa the #1 city in the world for tree cover). We obviously have tall palm trees but we have a lot of huge oaks. Massive amounts of trees and branches would come down on properties and streets, power outages would be extensive. All that falling and standing water would do a number on structures. With that stall easterly fetch would also push a ton of water around and carve up east facing shoreline. I'm not a hydrologist so I'm sure there's plenty of other impacts on infrastructure and public health.
Overall, a sub-optimal amount of rain and scenario.
