A coastal flood advisory is in effect through Thursday afternoon for San Francisco Bay, San Pablo Bay, Monterey Bay and the Pacific coast, as record-high October tides bring flooding without any rain, the San Francisco Chronicle reported.
Water could rise up to 2 feet above a typical high tide, flooding low-lying roads, parking lots and shoreline trails around midday high tides.
By the numbers
The San Francisco tide gauge was forecast to hit 7.4 feet at 11:39 a.m. Monday, about 1.6 feet above normal, SFGate reported.
About a foot of that is a surge partly linked to El Niño.
No rain is in the Bay Area forecast for the next five days.
What's next
The Chronicle says an El Niño-fueled jet stream could aim storms at the California-Mexico border this weekend, with heavy rain likely in Southern California. Whether the Bay Area gets wet is still uncertain.
Avoid driving through flooded roads near the shoreline, and check tide times before heading to waterfront paths.
