San Luis Obispo County braced for another day of big waves and pounding surf on Saturday after an overnight storm brought more than an inch of rain to most areas. San Luis Obispo received 1.67 inches of rain, while 1.6 inches fell in Arroyo Grande, 1.43 fell in Cambria and 0.9 fell in Templeton. Rocky Butte received the highest 24-hour total at 2.56 inches. The National Weather Service issued a flood advisory advisory late Friday night due to heavy rainfall across the Central Coast. The Weather Service said Doppler radar indicated heavy rain “due to moderate to locally heavy rainfall,” at 11:32 p.m. with rainfall rates between 0.25 and 0.50 inch per hour, which could cause minor flooding in low-lying and poor drainage areas.
