Images begin with the current day and will loop though the following 180 hours. IF YOU DON'T SEE AN IMAGE, THEY ARE MOST LIKELY BEING UPDATED, usually around 11:30 am EST daily. Each day will display for two seconds and after 3 cycles, the loop will stop and you will need to click here to restart the auto loop. Mousing over the map will temporarily pause the loop.
