Sacramento, Calif., (July 6, 2017) – A ridge of high pressure sat over the western United States, which resulted in another hot and dry week across the State. The only rain for the week was along the northern coast, where Eureka reported four hundredths of an inch for the week. A broken band of snow approximately 40 miles wide between Lake Tahoe and Sequoia National Forest still existed above 9,000 feet. Snow depths in this band were two to four feet at most. The peaks of Mt. Whitney, Mt. Lassen, and Mt. Shasta remained snow-capped.

Alfalfa fields were making excellent progress and being irrigated. Corn and sorghum planting for silage were almost complete, but still being cultivated and irrigated.

Cotton continued to be irrigated, cultivated, and was growing well. Black-eyed beans continued to be irrigated and cultivated.
Peach, nectarine, apricot, and plum harvests continued. Fruit orchards and vineyards were irrigated. Some apple orchards used overhead cooling systems to mitigate the impact of the heat. Late Navel orange harvest was complete for the season. Valencia orange harvest continued. With high temperatures, regreening in citrus has become more common, and packers were color sorting to compensate. Ruby Red grapefruit were harvested.
