Probabilistic Wind Speed Guidance
The Ocean Prediction Center is making available, on an experimental basis, forecast images that depict the
probability of 10-meter winds reaching or exceeding various thresholds (e.g greater than or equal to 34 knots).
The probabilities are produced from both the the North American Ensemble Forecast System (NAEFS) and the
Global Ensemble Forecast System (GEFS). Use the links below
to view the images.
