The latest California Crop Weather report from the Sacramento, Calif. Field Office of the National Agricultural Statistics Service.

Weather

The week of Oct. 18 started with a low pressure system located off Southern California while high pressure over western Oregon moved towards Northern California. This unusual pattern resulted in two separate weather regimes for California. Northern California enjoyed a mild and dry pattern through Thursday.

In Southern California, the low pressure system spread a rainy Pacific storm system across the region which persisted through Thursday resulting in cool temperatures and widespread showers, some locally heavy.

On Thursday, the pattern started to reverse. A low pressure system off the coast of British Columbia intensified and moved south while a high pressure ridge developed over Southern California.

By the weekend, Southern California enjoyed dry and mild weather. Northern California had a trio of Pacific storm systems move through; each one stronger than the previous storm. On Sunday, the strongest of the storms spread heavy rain, gusty winds, and high elevation snow to the north.

Field crops

The rice harvest progressed in the Sacramento Valley along with the baling of rice straw. Weekend rains brought harvest to a halt and strong winds flattened some fields.

The cotton harvest continued with fields ready in the San Joaquin Valley (SJV). Alfalfa was cut and baled. Some cut hay fields received rain late in the week. New fields of alfalfa were planted.

Corn was harvested for grain and silage. The potato harvest slowed in northern California. The bean harvest continued and the straw from finished fields was baled.
