The Flood Watch continues for * Delaware, northeast Maryland, most of New Jersey, and portions of southeast Pennsylvania. * From tonight through late Friday night * Periods of light to moderate rain will continue today, and then heavier rainfall will move into the area later tonight. Periods of moderate to heavy rain will persist through at least Friday night, and possibly into the weekend. General rainfall amounts of 2 to 4 inches are expected over the next 72 hours with the highest totals occurring along and south of the Interstate 78 corridor. Locally higher amounts over 5 inches are possible in slow-moving thunderstorms. * A variety of flooding types are possible. Low-lying and poor drainage flooding will be the most common type of flooding to develop. Flash flooding will also be possible if thunderstorms repeatedly move over the same locations, especially in urban areas where rainfall runoff is maximized and where small creeks and streams respond quickly. Flash flooding occurs quicker than other types flooding due to the torrential rain thunderstorms can produce in a short amount of time. Several days of excessive runoff will eventually lead to a risk of flooding in larger streams and rivers though the extent of the flooding will depend on where the heaviest rain falls. PRECAUTIONARY/PREPAREDNESS ACTIONS... A Flood Watch means there is a potential for flooding based on current forecasts. If you live across the Passaic, Raritan, and Rancocas basins in New Jersey or the Neshaminy, Schuylkill, and Brandywine basins across Pennsylvania and Delaware, keep an eye on later river forecasts. These forecasts, as well as all of our hydrologic forecasts, can be accessed via our Advanced Hydrologic Prediction Service website. Those living in areas prone to flooding should be prepared to take action should flooding develop. &&
