Guidance is not the forecast

Models are input, not output. A global model's grid is far coarser than Grenada is wide, so it cannot resolve the difference between the windward and leeward coasts — a difference that dominates the local weather.

The forecaster's job is to interpret that guidance against local behaviour, the observing network and the current satellite picture. Where the published forecast differs from a model chart on this page, the published forecast is the official product.
