Welcome to the GEFS Model, operational four times daily with a sleek 50km resolution. Developed by the visionary minds at the National Centers for Environmental Prediction (NCEP), the Global Ensemble Forecast System (GEFS) isn't your average weather model—it's a game-changer. Generating a whopping 31 distinct forecasts (ensemble members), GEFS tackles the inherent uncertainties lurking in our input data with finesse. Whether it's limited coverage, instrument biases, or model limitations, GEFS has it covered. By unleashing a barrage of forecasts, each compensating for a unique set of uncertainties, GEFS paints a vivid picture of potential outcomes, guiding us through the maze of atmospheric complexity.

We stretch our forecasts out to a robust 16 days, with updates every 6 hours, ensuring you're always ahead of the weather curve.
