* From Thursday evening through late Friday night

* Periods of light to moderate rain will continue this afternoon through tomorrow. A brief break in the rain is expected early tomorrow evening before it once again intensifies and becomes more widespread tomorrow night. Periods of moderate to heavy rain are then expected to persist into at least Friday, possibly into the weekend. General rainfall amounts of 2 to 4 inches are expected the next 72 hours with the highest totals along and south of the Interstate 78 corridor. Locally higher amounts are possible across the same area as thunderstorms are expected to periodically develop.

* A variety of flooding types are all possible within the Flood Watch area. First, low-lying and poor drainage flooding is the most likely type of flooding to develop. Second, flash flooding will be possible under the stronger thunderstorms. Flash flooding occurs quicker than other types flooding due to the torrential rain thunderstorms can produce in a short amount of time. Flash flooding is most likely to occur across urban areas where rainfall runoff is maximized and where small creeks and streams respond quickly. The rain has to go somewhere and eventually leads to larger streams and rivers. This is where the third type of flooding is possible. 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 forecasts. These forecasts, as well as all of our hydrologic forecasts, can be accessed via our Advanced Hydrologic Prediction Service website.
