Magnetic North Pole Shift Affects KTPA

This is certainly not a rare event - happens reasonably regularly - although often airports will leave the runway designator for as long as possible (outside of the +/- 5 degrees) as it is a lot easier.
For example, Perth airport runway 21 has a magnetic track of 196!
Other reasons to ignore the actual magnetic track are for clarity - such as LAX 24 and 25.
Hurts my brain to think too much about the poles moving though!
