Why a small service depends on its neighbours

Weather arrives in Grenada from the east, having crossed thousands of kilometres of open ocean where there are no observations. What the island knows about tomorrow depends heavily on satellite imagery, model guidance and upper-air soundings shared across the region.

The exchange runs both ways. Grenada's observations are one of the few surface reports in the southern Windward Islands, and they matter to every forecast office downstream.

This is why standards work is not bureaucracy. A regional network only functions if everyone measures and codes the same way.
