I have been away from the weather for most of the past week, as I had to prepare a book catalogue for mailing before the Labor Day weekend. I now have a bit of time to catch up on weather events and the like.
Jim Means, who is an avid storm watcher and monsoon follower, sent information at the first of the week, as per:
"Finally a big monsoon today over here in Southern California. The combination of an upper level disturbance offshore from San Diego and a deep moisture field (PW ~ 2") from the remnants of Hurricane Dean gave San Diego County its best monsoon day in quite a while. Lifting caused by the upper level disturbance initiated storms before sunrise, and the NWS in San Diego had to issue an unusual Flash Flood Warning for the area around Escondido, about 25 miles north of San Diego. A strong (but not severe) storm produced flash flooding and some areas got more than 2 inches of rain in about an hour and a half. Another storm occurring at the same time produced a waterspout offshore from San Clemente. Daytime heating later generated another flash flood producing storm in the area of Anza Borrego Desert State Park, where people had to be rescued from their cars in what are normally dry washes. This storm generated 3 inches of rain in some places and the NWS reported the top at 60,000 feet."
Jim, who lives in Alpine CA - which is east of San Diego along I-10, has sent a couple of photos of interest:
Photo 1, taken by Jim at sunrise on Sunday 26 August, shows the early morning storm near Escondido, north of Alpine.
Photo 2 shows Escondido Creek still running in flood on Monday morning.
