† Data updates for Catalina Airport weather station were missing for sporadic periods over the three days from Dec. 24 through Dec. 26. Consequently, an unknown amount of rainfall data was missed. Data from another Santa Catalina Island weather station (Dakin Peak station, 1.55 miles NW of Avalon) reported 2.03 inches of rainfall from Dec. 24-26. The Almanac considers rainfall reports here, Dec. 24 through Dec. 26, to be incomplete.
