The National Weather Service in Mount Holly has issued a * Flood Watch for portions of Delaware, northeast Maryland, New Jersey, and Pennsylvania, including the following areas, in Delaware, Delaware Beaches, Inland Sussex, Kent, and New Castle. In northeast Maryland, Caroline, Cecil, Kent MD, Queen Annes, and Talbot. In New Jersey, Atlantic, Atlantic Coastal Cape May, Camden, Cape May, Coastal Atlantic, Coastal Ocean, Cumberland, Eastern Monmouth, Gloucester, Hunterdon, Mercer, Middlesex, Northwestern Burlington, Ocean, Salem, Somerset, Southeastern Burlington, Warren, and Western Monmouth. In Pennsylvania, Berks, Delaware, Eastern Chester, Eastern Montgomery, Lehigh, Lower Bucks, Northampton, Philadelphia, Upper Bucks, Western Chester, and Western Montgomery. * 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. PRECAUTIONARY/PREPAREDNESS ACTIONS... A Flood Watch means there is a potential for flooding based on current forecasts. You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop. && $$ Kruzdlo

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. && $$ SFJ

Surface high pressure pushed south today across northern New Jersey and northeast Pennsylvania. This kept the rain to our south all day. As a result, the region did not pick up the rainfall that was expected. This rain to our south will slowly track to the north tonight back across the area, but it's also expected to be on the lighter side. For these reasons, the Flood Watch has been cancelled. $$ DEZ001>004-MDZ008-012-015-019-020-NJZ016>027-PAZ060-070-071- 101>104-190345- /O.CON.KPHI.FA.A.0004.000000T0000Z-180519T2200Z/ /00000.0.ER.000000T0000Z.000000T0000Z.000000T0000Z.OO/ New Castle-Kent-Inland Sussex-Delaware Beaches-Cecil-Kent MD- Queen Annes-Talbot-Caroline-Salem-Gloucester-Camden- Northwestern Burlington-Ocean-Cumberland-Atlantic-Cape May- Atlantic Coastal Cape May-Coastal Atlantic-Coastal Ocean- Southeastern Burlington-Berks-Delaware-Philadelphia- Western Chester-Eastern Chester-Western Montgomery- Eastern Montgomery- Including the cities of Wilmington, Dover, Georgetown, Rehoboth Beach, Elkton, Chestertown, Centreville, Easton, Denton, Pennsville, Glassboro, Camden, Cherry Hill, Moorestown, Mount Holly, Jackson, Millville, Hammonton, Cape May Court House, Ocean City, Atlantic City, Long Beach Island, Wharton State Forest, Reading, Media, Philadelphia, Honey Brook, Oxford, West Chester, Kennett Square, Collegeville, Pottstown, Norristown, and Lansdale 338 PM EDT Fri May 18 2018 ...FLOOD WATCH REMAINS IN EFFECT THROUGH SATURDAY AFTERNOON...
