While downtown LA saw an all-time record high of 113 Monday, the National Weather Service official high temperature in San Gabriel, 110, failed to be all-time record by two degrees. (On September 4, 1988 it reached a record high of 112.) Monday's heat did break the previous hottest September 27, which was in 1963.
All-time record or not, the heat was enough to trigger a power outage on Valley Boulevard. Benjamin Orozco, owner of Alhambra Computer Services, captured these images. (Orozco closed his business for the day, thinking that the heat would stress his breaker. In the end, the air conditioning broke anyway.) The World Journal reported that many businesses had to shut down temporarily, including 99 Ranch Market, one of the the largest Chinese supermarkets on Valley Boulevard which was out of business for nearly three hours before power came back.
