Read the full account →Low pressure moving southeastward into central CA from the Pacific Northwest allowed subtropical moisture stream to be pumped into the region bringing heavy rainfall to the San Joaquin Valley and foothill areas. Orographic lifting caused intensification of rains at times.
Read the full account →The month began with a ridge of high pressure over the Great Basin and moderate easterly flow in the mid and upper levels. This allowed monsoon moisture to surge into the southern half of California August 1st-3rd.
Read the full account →A vigorous Pacific low pressure system spread copious amounts of moisture northward and into southeastern California during the morning hours on January 30th. As a result, widespread showers occurred over eastern Riverside county, and they produced locally heavy rainfall.
