¿Estás listo para el invierno? Se espera un fenómeno de El Niño muy intenso este año, mantente informado y prepárate hoy

The County of Sonoma Board of Supervisors has proclaimed an emergency in preparation for a potentially historic El Niño season predicted to bring unusually heavy rains, multiple storms and significant flooding risks this winter.

The County’s emergency proclamation directs County departments, Sonoma Water, and sanitation districts to prepare a countywide prioritized list of threatened or vulnerable infrastructure. It directs County departments to coordinate a response with cities, special districts, tribal partners and state emergency managers.
