How this forecast works

FloodRoute combines NOAA tide predictions for the Sewells Point station with the elevation of every road segment in Norfolk. 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 Sewells Point 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 8638610 (Sewells Point). Updated 1:59 AM.

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

Roads start to flood when the tide at NOAA's Sewells Point station passes about 3.4 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 Norfolk?

Thu, Oct 22 at 6:41 AM EDT: a 2.6 ft high tide predicted at NOAA's Sewells Point 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 Norfolk?

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 Norfolk flood calendar and flood days appear on your calendar automatically.

How accurate is the Norfolk flood forecast?

It's an estimate built from NOAA tide predictions for the Sewells Point station, corrected with live readings from the NOAA Sewells Point gauge, and the measured elevation of every road segment in Norfolk. Norfolk 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.
