VIMS Stations
These stations are in Newport News (NN), Virginia Beach (VB), and Norfolk (NF), and several NOAA/NOS stations in Virginia
Legend Definitions & Datum
Sensor Observation (dashed = forecast)The solid red line shows the observed water level (unverified data from the U.S. National Oceanic and Atmospheric Administration). The dashed red line shows our water-level forecast for the next 36 hours. |
Predicted Astronomic (m30) TideThe blue line shows our prediction of the astronomic tide. This incorporates two factors:
|
Residual (dashed = forecast)The green line is the residual difference between the predicted astronomic tide and the observed water level. Values are positive when observed values exceed predicted values, and negative when observed values fall below predicted values. The solid green line shows the observed residual; the dashed green line shows our forecast for the residual over the next 36 hours. |
NAVD88Observed and predicted water-level values are displayed in feet and referenced to the elevation benchmark North American Vertical Datum of 1988 (NAVD88). This is the datum in which house and road elevations are typically given. |
