The moisture extended into southern California and produced moderate precipitation across the region. Bakersfield reported a one-day rainfall record on September 4 with 0.23 inches (5.8 mm) of precipitation, breaking the previous record of 0.17 inches (4.3 mm) set in 1963. Rainfall amounts at Frazier Park peaked at 1.53 inches (39 mm). Agricultural losses, primarily from vintners and raisin growers, rose up to $5 million in damage (1998 USD, $6.33 million 2007 USD), either directly due to rain or indirectly due to the additional steps to treat the increase in fungus activity on produce. Slick roads from the rain resulted in nearly 80 traffic accidents in San Diego County, ranging from fender benders to moderate injuries. Thunderstorms from the remnants of Isis damaged a San Diego Gas & Electric substation at Kearny Mesa, leaving 10,000 customers without power; the outage was short lived and completely restored within two hours. About 1,000 homes and businesses were temporarily without power in Escondido, and another 2,700 customers lost electricity in Rancho Bernardo. Rainfall in and around San Diego reached a maximum of 0.5 inches (13 mm) at La Mesa. Heavy clouds from Isis produced scattered rainfall and temporary relief to severe heat conditions in the Los Angeles area.
