| Area Forecast Discussion National Weather Service Mount Holly NJ 413am EDT Monday September 28 2026 .WHAT HAS CHANGED... Coastal Flood Advisory added for Atlantic and Cape May Counties. .KEY MESSAGES... 1. The nor'easter slowly departs the region on Monday. 2. Coastal flooding threat lowered in many areas but still a concern along the back bays of New Jersey and Delaware. 3. A cold front is likely to cross through the region Friday into Saturday. KEY MESSAGE 1...The nor'easter slowly departs the region on Monday. The nor'easter is now centered just offshore the NJ coast, with high pressure centered to the north. The low will continue to weaken as it tracks slowly northeastward. Winds have now weakened substantially compared to the past few days, now only around 10 mph or so during the day out of the N to NW. Shower coverage will continue to diminish as well, with the best chance for an isolated to scattered shower north earlier in the day with Probability of Precipitation chances decreasing through the afternoon. Cloud coverage will linger through most of the day, though some breaks in the clouds will be possible late afternoon south and west. KEY MESSAGE 2... Coastal flooding threat lowered in many areas but still a concern along the back bays of New Jersey and Delaware. A Coastal Flood Advisory was added for Atlantic and Cape May counties for minor tidal flooding during this morning's high tide. Despite the weak offshore flow, back bays and other tidal waterways are slow to drain and could see minor tidal flooding as a result. Further north, the onshore flow and continued effects of the Nor'easter will keep high tides Monday morning at Minor flooding levels. For those areas, a Coastal Flood Advisory remains in effect Monday morning. One exception, is Ocean County NJ, where we have kept the Coastal Flood Warning with the effects of high water in the back bays continuing. The warning presently goes until Monday 2 PM, but may need to be extended. Further south, high water for back bays across Southern Delaware (including Rehoboth Bay, Indian River Bay and Little Assawoman Bay) remain a concern, so a Coastal Flood Warnings for Sussex County Delaware remains in effect until Monday 2 PM. For Delaware Bay communities, a strengthening Northwest wind will remain across Delaware Bay into tonight. This will promote lowering tidal departures as the waters is pushed down/out Delaware Bay. As a result, additional flooding (at high tides) will be spotty Minor or less. No additional flags for tidal flooding are expected. For the tidal Delaware River, the North to Northeast flow has kept water levels (at high tide) at the lower part of Minor flooding range. No flags for tidal flooding are expected. KEY MESSAGE 3...A cold front is likely to cross through the region Friday into Saturday. The surface high that will be over the region for much of the week will start to build southeast and off shore by Thursday. This will open the door for a cold front to sweep through the region Friday or Saturday. Models for the most part, aren't depicting a widespread rain event with this front. However, southwesterly flow on Wednesday and Thursday, should set the stage with ample moisture in place. The biggest question is forcing with this front. The best synoptic scale lift will likely be well removed from the mesoscale forcing associated with the front. For now the 20 to 30 percent Probability of Precipitation through this period seem appropriate this far out. Preliminary guidance indicates that temperatures behind the front could be 5 to 10 degrees colder than normal. Marine Small Craft Advisories were allowed to expire or were cancelled with the exception of the nearshore waters of Monmouth and Ocean counties where the SCA (Small Craft Advisory) continues until 2PM this afternoon. Seas 3-5 feet. Visibility restrictions in rain and some spray will remain possible into Monday morning. Outlook... Tuesday through Friday...winds and seas should stay below SCA (Small Craft Advisory) criteria. Rip Currents... For Monday...Light offshore winds will prevail from the NNW to NW around 10 kts with wave heigheights around 2-4 feet in the surf zone. A lingering east- northeasterly 2 foot 9 second swell will, however, keep the risk for rip currents elevated. As a result, a Moderate Risk for rip currents is forecast for all area beaches. For Tuesday...Offshore winds from the WNW diminish to around 5-10 kts with wave heigheights falling to 2-3 feet in the surf zone. A weak 2 foot 8 second easterly swell lingers. With improving conditions, a Low Risk for rip currents is forecast for all area beaches. NOAA Mount Holly NJ Office: Watches - Warnings - Advisories PA...None.
