Event 201 for Hurricane Milton: Project Phoenix Training Exercise.

The Tampa Bay Regional Planning Council developed a planning exercise it labeled "Project Phoenix," which simulated the effects of a direct strike from a Category 5 hurricane.

The fictitious hurricane produced a storm surge of around 40 feet along the coast, and downtown Tampa saw a water rise of 10-15 feet.

The estimated cost of damage was in the hundreds of billions of dollars, which would make the event the costliest in U.S. history, if it ever comes to fruition.
