This is an experimental web portal for graphic visualization of the operational and experimental results from the storm surge and tide forecast systems being developed and tested by the National Ocean Service (NOS/OCS) and the National Weather Service's Model Development Laboratory (NWS/STI).

STOFS and ETSS model outputs are NOT total water level guidance. Actual water levels can be significantly higher than forecast due to waves, steric effect and other components not presently included in the models.

Please check with your regional National Weather Service forecast office for the official water level forecast.

These graphics do NOT reflect total water level guidance, which can be much higher.

For total water level guidance, please consult Weather Service.
