How this forecast works
FloodRoute combines NOAA tide predictions for the Sausalito station with the elevation of every road segment in Larkspur. 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.
Tide source: NOAA station 9414806 (Sausalito). Updated 10:50 PM.

How accurate is the Larkspur 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 Larkspur. Wind, storm surge and blocked drains can change what actually floods. Never drive through flood water.
