## How this forecast works

FloodRoute combines NOAA tide predictions for the Sausalito station with the elevation of every road segment in Novato. When the predicted water level rises above a road's lowest point, it's marked — amber for possible, orange for likely, red for severe. The NOAA San Francisco gauge shows how far the water is actually running above or below the tide tables; that difference is carried into the forecast and fades over the following days. Recent rain raises the next 24 hours. After each high tide, streets stay marked a little longer, because water drains off the road more slowly than the tide falls.

**Estimates only.** Never drive through flood water — six inches can float a car. Follow local authorities.

### How high does the tide have to be to flood roads in Novato?

Roads start to flood when the tide at NOAA's Sausalito station passes about 6.0 ft (MLLW). Higher tides flood more streets, for longer. FloodRoute marks flooding as possible when the water is less than 0.5 ft above a road's low point, likely up to 1.5 ft, and severe at 1.5 ft or more.

### When is the next king tide in Novato?

Sat, Oct 24 at 10:49 AM PDT: a 5.7 ft high tide predicted at NOAA's Sausalito station. FloodRoute calls a high tide a king tide when it is more than 0.7 ft above the station's mean higher high water (MHHW).

### How can I get flood alerts for Novato?

The free FloodRoute iPhone app gives you a heads-up before flood windows in your home town; FloodRoute Pro adds street-level alerts for your saved places and your commute. Without the app, subscribe to the [Novato flood calendar](https://floodroute.com/cal/ca/novato.ics) and flood days appear on your calendar automatically.

### How accurate is the Novato flood forecast?

It's an estimate built from NOAA tide predictions for the Sausalito station, corrected with live readings from the NOAA San Francisco gauge, and the measured elevation of every road segment in Novato. Wind, storm surge and blocked drains can change what actually floods. Never drive through flood water.
