2. How are these forecasts made?

The forecaster uses computer model guidance, climatology, and bias calculations, along with their understanding of the complex interactions of tides, waves, weather, and water levels to make these forecasts.

3. Why are some locations always “grayed” out?

The colors indicate forecast flood categories for the chosen tide cycle (slider bar in upper left). The colors are dependent on the weather offices sending the "table” information below the hydrograph. For some locations the tables are not provided due to a variety of factors:

Forecasting knowledge is still under development
Occasionally, the forecast high tide time is already past the current time
A few locations are considered “river forecasts” but are also tidal in nature; these locations will never have forecast tables.

FEMA Flood Maps

FEMA flood map service is the official public source for flood hazard information produced in support of the National Flood Insurance Program.

NOAA Sea Level Rise Viewer

Provides depictions of sea level rise and potential coastal flooding impact areas.

NOAA’s Coastal Flood Exposure Mapper

Helps to start your community discussions about hazard impacts with maps of your area that show people, places, and natural resources exposed to coastal flooding.

NWS/OCM Minor, Moderate, Major Flood Threshold Maps

highlight flood-prone areas based on the NWS flood category thresholds.

Federal Coastal Flood Model Guidance

Note: Model guidance does not provide estimates of the entire water level at the coast. Actual water levels for a coastal flooding event may vary due to factors such as rainfall and wave action. Please see Coastal Hazard Map for official National Weather Service forecasts.
	ETSS Storm Surge Model This product is experimental total water level model guidance for tide gauges. Water level guidance is for extra-tropical storms.
