Northern Sierra set to break record for driest January-February

California is poised to shatter an all-time weather record by notching the driest January-February period in recorded history across the northern Sierra Nevada.

The Northern Sierra is crucial to statewide water supplies because it is where snowmelt accumulates to fill Shasta and Oroville reservoirs. These are the largest reservoirs in California and the primary storage points for state and federal water supply systems.
