## How this forecast works

FloodRoute combines NOAA tide predictions for the St. Petersburg station with the elevation of every road segment in Saint Petersburg. 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 St. Petersburg 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.

## Frequently asked questions

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

Roads start to flood when the water at NOAA's St. Petersburg station reaches about 3.7 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 Saint Petersburg?

Wed, Nov 25 at 12:25 AM EST, with water expected around 3.7 ft at NOAA's St. Petersburg station. King tides are the year's highest predicted tides: FloodRoute uses the top 5% of high tides in NOAA's tide tables, 2.8 ft or more at NOAA's St. Petersburg station, about 18 days a year. Water often runs above the tide tables for weeks at a time (warm water, El Niño, storms). FloodRoute's flood forecasts include that, but it doesn't turn an ordinary high tide into a king tide.

### How can I get flood alerts for Saint Petersburg?

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 [Saint Petersburg flood calendar](https://floodroute.com/cal/fl/saint-petersburg.ics) and flood days appear on your calendar automatically.

### How accurate is the Saint Petersburg flood forecast?

It's an estimate built from NOAA tide predictions for the St. Petersburg station, corrected with live readings from the NOAA St. Petersburg gauge, and the measured elevation of every road segment in Saint Petersburg. Saint Petersburg is in Beta: community reports are still confirming which streets flood. Wind, storm surge and blocked drains can change what actually floods. Never drive through flood water.
