Feed updated to leverage forecast model change by NOAA, whereby the
Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT)
forecast model system was replaced with the Rapid Refresh (RAP) forecast
model system. Key differences: higher accuracy with RAP now
concentrated at 0-8 meter detail vs HYSPLIT at 0-100 meter; earlier data
delivery by 6 hrs; forecast output extended to 51 hrs.<br /></li></ul></div><span style='color:rgb(128, 128, 128);'></span></div><div><span style='color:rgb(128, 128, 128);'>This map is provided for informational purposes and is not monitored 24/7 for accuracy and currency.</span><div><br /></div>If you would like to be alerted to potential issues or simply see when this Service will update next, please visit our <a href='https://livingatlas.arcgis.com/livefeeds-status/' target='_blank' rel='nofollow ugc noopener noreferrer'>Live Feed Status</a> Page!</div></div></div>
