California has a diverse hydrological system with major surface flows, including the Sacramento and San Joaquin River systems, which provide water to the agricultural heartland. The state has numerous reservoirs and dams, including the Oroville Dam, which is the tallest in the US. California's climate is characterized by long periods of drought, punctuated by occasional heavy rainfall events. The state's hydrology is heavily influenced by snowpack, which accumulates in the Sierra Nevada mountains during the winter and provides a critical source of water during the dry season. The state's watersheds are also important, with the Sacramento River being the largest, providing water to much of Northern California. Overall, California's water management is complex and requires careful planning to balance the competing demands of agriculture, urban areas, and the environment.

Residents across California are urged to prepare for a series of potentially dangerous natural events. The National Weather Service has issued High Wind Watches for multiple regions, including Mendocino and Lake Counties, the Bay Area, Central Siskiyou, and Modoc County, warning of southeast winds with gusts up to 80 mph which could lead to downed trees, power outages, and hazardous travel conditions, especially for high-profile vehicles. Concurrently, Winter Storm Watches warn of heavy snow accumulations, affecting areas above 4500 feet in Siskiyou County, parts of Modoc County, central California regions, and Yosemite National Park outside of the valley, with potential for treacherous road conditions and significant travel disruptions. Flood watches are also in place for parts of Orange County, Los Angeles County, San Bernardino County, and Malibu due to expected heavy rains. Citizens are advised to exercise extreme caution, prepare for potential power outages, and postpone travel plans if possible to avoid the risks associated with these severe weather conditions.
