A weak late-season Pacific storm brought showers to the region last week, providing another reprise from the anomalous heat the region has been experiencing since the beginning of March.

Precipitation totals were fairly consistent, averaging around 0.2 inches across the majority of WeatherCurrents stations. Simi Valley led the WeatherCurrents stations with 0.57 inches, while the driest total belonged to Pinon Hills with 0.05 inches. In Temecula Valley's Wine Country, a notable total of 0.68 inches was reported (courtesy of Jim Sappington), while in Riverside's Canyon Crest neighborhood, 0.21 inches was reported (courtesy of Jim Ness). The storm offered some relief from the warm, dry conditions that have dominated the region since March.

Here are the rain totals for the WeatherCurrents network and associates:

1. French Valley season total incomplete.
