As tropical system Erin moves northeast away from the Eastern Seaboard, New Jersey is finally shaking off any immediate threats of coastal flooding or heavy showers. While the storm itself is no longer a direct hazard, its lingering influence on the ocean and coastal waters means beachgoers still need to exercise caution. Dangerous rip currents and larger-than-normal waves are expected to persist through Saturday, making today and tomorrow the final days when swimming may be unsafe along New Jersey’s shorelines.
For residents and visitors, respecting lifeguard instructions and local advisories is key before venturing into the ocean this weekend. By Sunday, conditions are expected to stabilize, with calmer surf and safer swimming conditions for those hoping to enjoy a final dip before Labor Day weekend.
What Erin’s Departure Means for New Jersey
Erin’s exit is reshaping the regional weather in a few key ways. Ahead of the storm, warm and humid air was pushed northward, while its trailing influence is ushering in cooler, drier air across the state. For Friday and Saturday, this translates to blue skies, low humidity, and very pleasant conditions—ideal for outdoor activities, beach walks, and late-summer evenings under clear skies.
Meteorologists expect a small ridge of high pressure to build Saturday night into Sunday, followed by a trough moving down from Canada and the Great Lakes. This pattern will bring slightly warmer temperatures, rising humidity, and a chance for afternoon and evening showers or thunderstorms on Sunday and into Monday. A cold front is projected to sweep through Monday night into Tuesday, restoring low humidity and ideal weather conditions that should persist through Labor Day weekend.
