How this works
Tide tables predict the water. Right now the ocean is running higher than the tables because of a very strong El Niño, so we measure how much higher at the San Francisco tide gauge and add it. Then we combine that with the rain forecast. When the water passes about 6 feet, the low roads near Tam Junction tend to flood.
