## How this forecast works

FloodRoute combines NOAA tide predictions for the North Fork station with the elevation of every road segment in Port St. Lucie. 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 Lake Worth Pier 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

### Which roads flood in Port St. Lucie?

No roads in Port St. Lucie are forecast to flood in the next 30 days. Roads start to flood when the water at NOAA's North Fork station reaches about 2.7 ft (MLLW). The [live map](https://floodroute.com/fl/port-saint-lucie) has a tide scrubber to see the week ahead.

### When is the next flood in Port St. Lucie?

No flooding is forecast in Port St. Lucie in the next 30 days.

### How high does the tide have to be to flood roads in Port St. Lucie?

Roads start to flood when the water at NOAA's North Fork station reaches about 2.7 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 Port St. Lucie?

Tue, Nov 24 at 10:28 AM EST, with water expected around 2.6 ft at NOAA's North Fork station. King tides are the year's highest predicted tides: FloodRoute uses the top 5% of high tides in NOAA's tide tables, 1.4 ft or more at NOAA's North Fork 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 Port St. Lucie?

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 [Port St. Lucie flood calendar](https://floodroute.com/cal/fl/port-saint-lucie.ics) and flood days appear on your calendar automatically.

### How accurate is the Port St. Lucie flood forecast?

It's an estimate built from NOAA tide predictions for the North Fork station, corrected with live readings from the NOAA Lake Worth Pier gauge, and the measured elevation of every road segment in Port St. Lucie. Port St. Lucie 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.
