A better way to view storm tides in Chesapeake Bay
Tidewatch is a system developed by VIMS emeritus professor John Boon that measures and forecasts the difference between the predicted astronomical tide and observed water levels at 10 locations within Chesapeake Bay and along Virginia's seaside Eastern Shore. This difference—the residual—represents non-tidal, weather-induced change in water level including storm surge.
Tidewatch charts provide an effective way to measure, visualize, and predict the magnitude and impacts of coastal flooding in a given location. The use of Tidewatch charts can help forecasters and coastal residents better prepare for storm tides and minimize their potential impacts. They are particularly useful for comparing storm tides in areas with different tidal ranges.
Tidewatch operates at 10 stations. Access observations and forecasts for individual stations using the links or Google Map below, or view a single graph that compares water-level forecasts among all the stations.
