Northwest wind lowers bay water levels
Have you noticed unusually low water around the bay today? That would be the work of the gusty northwest winds, which have been pushing water down the bay. The effect is especially noticeable in the upper tidal Potomac and Baltimore Harbor, according to the National Weather Service.
Here's the water level forecast from NOAA, predicting water levels as much as 2 feet below predicted tidal levels (dark blue).
