The National Weather Service is expected to issue a special Airport Weather Warning for San Francisco International this afternoon. An AWW addresses weather phenomena that may adversely impact ground operations at airports, and is usually issued just prior to the onset of severe weather. Weather conditions, specifically erratic winds, will likely disrupt regular airport operations. In the upper left column of this page is a map of real-time airport delays and problems.
