Heavy rains from December through April along the central California coast supported significant growth of the regional vegetation, which gave this section of California an unusually green cast. This image (NASA photograph NASA7-709-029), taken in March 1998, centers on San Francisco Bay. The urban region around the bay contrasts strongly with the green vegetation on the surrounding hillsides. The graph shows the regional precipitation deviations due to El Niņo. The cumulative observed precipitation is given by the heavy solid line, and normal precipitation (cumulative) is depicted by the thin dashed line. The red bar indicates when the photo was taken.
