Models say tropical hail damage may ease. What starves hail growth?

Answer: Limited growth depth

No thunderstorms form — No. Tropical regions have plenty of thunderstorms, so the issue is not simply storm absence. The question is whether hail has enough vertical room and storm structure to grow into damaging sizes. A humid tropical storm can be loud and rainy without being a good hail factory.

Limited growth depth ✓ — Correct. Nature points to weak warming, strong moistening and limited hail-growth depth in tropical and monsoonal regions. Hail embryos have less effective cold-growth space before the lower warm, wet atmosphere works against them. The surprise is that mid-high latitudes can get stronger instability while the tropics get lower hail potential.

Hail turns into snow — No. Hail falling through tropical warm air is more likely to melt toward rain, not turn into snow. Snow needs a colder temperature profile near the surface. Here the deeper lesson is about missing growth space inside the storm, not a switch from one frozen precipitation type to another.
