.TIDES/COASTAL FLOODING... We have been keeping an eye on the Saturday morning high tide as it relates to the expected coastal storm. Fortunately, conditions are lining up to preclude the development of any significant tidal flooding. A north northeast wind is forecast to develop on Friday evening, with wind speeds increasing on Friday night. Ekman transport will begin to push water toward the coast. However, the period of time with an onshore push leading up to Saturday morning's high tide will be somewhat limited (less than 12 hours). We will need a surge of +1.2 to +1.4 feet to begin causing minor flooding along the coasts of Delaware and New Jersey at that time. Based on the latest guidance, we should exceed those values by only a few tenths of a foot, mainly in southern Delaware and in Cape May County, New Jersey. As a result, we are anticipating the potential for widespread minor flooding at those locations. Only spotty minor flooding is expected along the rest of the New Jersey coast and along Delaware Bay. There should be no flooding along the tidal Delaware River or on the upper eastern shore of Chesapeake Bay. Even as the wind backs to the northwest for Saturday evening, water levels along the coast should remain elevated. Saturday evening's high tide is the lower of the two daily high tides, so no flooding is forecast at that time. Some of the guidance is hinting at a lingering round of minor flooding with Sunday morning's high tide before the water begins to drain away from the coast. &&

Our Advanced Hydrologic Prediction Service (AHPS) page also includes information about other tide gauges in our area. You can find the flood impacts at certain water levels, as well as historic crests and low water values on the AHPS page.
The values listed under Flood Impacts refer to the water level at the tide gauge. The heights are not to be interpreted as an indication of the water level at the actual locations mentioned in the corresponding impact statements. Those locations are often a number of miles away from the reference gauge.
It is important to remember that the impact statements are based on estimates. A number of factors can cause the flooding associated with a particular tide level to vary somewhat from event to event. Those factors include rainfall, wave action and the number of tide cycles during which there is an onshore flow.
Being that the impact statements are based on estimates, it may be best to place more emphasis on the descriptive categories of flooding rather than focusing on the specific height values associated with flooding at a given location. The three categories (minor, moderate, major) provide a much better overall picture of the type of tidal flooding that can be expected in the area.
In the MINOR category there is flooding of the most vulnerable roadways due to high water and/or wave splash-over. The majority of roads remain passable. There is no significant threat to life. Any impact on property is minimal. This type of event is covered by a Coastal Flood Advisory.
In the MODERATE category there is widespread flooding of roadways due to high water and/or wave action with many roads becoming impassable. Lives may be at risk when people put themselves in harm’s way. Some damage to vulnerable structures may occur. This type of event is covered by a Coastal Flood Warning.
In the MAJOR category there is flooding that is severe enough to cause structural damage along with widespread flooding of roadways. Some evacuations become necessary. Vulnerable homes and businesses may be severely damaged or destroyed. Numerous roads become impassable and some neighborhoods may be isolated. The flood waters become a danger to anyone who attempts to cross on foot or in a vehicle. This type of event is covered by a Coastal Flood Warning which may contain enhanced wording to emphasize the significant threat to life and property.
