Rainfall Totals by Region
The San Gabriel Valley wasn’t the only area in Los Angeles County to receive significant rain. The San Fernando Valley also saw substantial amounts, particularly in La Cañada Flintridge, which recorded 1.83 inches. Other locations in the San Fernando Valley, including Woodland Hills (1.74 inches) and Northridge (1.63 inches), also received notable rainfall.

Inland areas like Ojai in Ventura County reported 1.11 inches. Even the Catalina Islands were not spared, as Catalina Island RAWS recorded 1.23 inches of rain.
What Does This Mean for Water Resources?
The recent rainfall is a welcomed sight for water officials, as it helps replenish local water reservoirs and assists in maintaining healthy groundwater levels. For cities like Pasadena and its surrounding areas, this rain will help improve the local water supply after a particularly dry summer.
However, it is important for residents to be cautious, as continued rainfall may lead to localized flooding and impacts in some areas. Local authorities urge residents to stay up to date with weather forecasts and avoid driving through flooded roadways.
