Effective on May 20, 2020 beginning at 18z Coordinated Universal Time (UTC), two major changes for NOS OFS datasets on THREDDS will be implemented. Please see the Service Change Notice for details

https://www.weather.gov/media/notification/scn20-43nos_ofs.pdf

1. Retention period change - Only the most recent 31 days of OFS output files will be available on CO-OPS THREDDS.

Wind Forecast Guidance
This wind animation depicts forecasted hourly surface (10m above the water) winds for the next 48 hours. The hourly wind fields were created by spatially and temporally interpolating wind forecast guidance from the National Weather Service's operational NAM atmospheric forecast model. These hourly wind fields were used by SJROFS to generate oceanographic forecast guidance for 48 hours.
