NJ Weather: Isaias Remnants Could Bring Heavy Rain Sunday
New Jersey’s recent run of sunny and comfortable weather could take a turn Sunday as the remnants of Tropical Storm Isaias move toward the state, potentially bringing periods of heavy rain.
According to the National Hurricane Center, Isaias is forecast to strengthen to hurricane status Thursday before reaching the Gulf Coast late Friday or early Saturday.
The National Weather Service office in New Jersey said the storm’s remnants are expected to approach the region later this weekend, with rain chances increasing as early as Sunday. Some areas could experience periods of heavy rainfall, with total amounts potentially reaching 1 to 2 inches.
N.J. Weather: Isaias Remnants Could Bring Heavy Rain Sunday
New Jersey’s stretch of quiet, comfortable fall weather could come to an end this weekend as the remnants of Tropical Storm Isaias move toward the region, bringing the potential for widespread rain and periods of heavy downpours.
The latest forecast from the National Weather Service indicates that rain could arrive as early as Sunday, with the storm system potentially continuing to affect New Jersey into early Monday. Forecasters say there are still some differences among weather models regarding the storm’s exact timing and track.
Tropical Storm Isaias formed Wednesday in the Gulf of Mexico and is expected to strengthen into a hurricane before reaching the northern Gulf Coast later this week. After making landfall, the system is expected to transition and move northeast toward the Mid-Atlantic.
Heavy rain possible across New Jersey
While the storm itself will not be directly impacting New Jersey as a tropical system, its remnants are expected to transport a significant amount of moisture into the region.
The National Weather Service said atmospheric moisture levels could become unusually high, creating the potential for periods of heavy rainfall. Current projections indicate that widespread rainfall totals could reach 1 to 2 inches, with locally higher amounts possible.
The Weather Prediction Center has placed much of the region under a Marginal Risk for excessive rainfall Sunday, meaning isolated areas could experience heavier rainfall and localized flooding issues.
Quiet weather before the rain
For now, New Jersey is expected to enjoy several more days of relatively tranquil weather.
A cold front is expected to pass through Thursday, followed by seasonable temperatures and generally dry conditions through Saturday. High temperatures are expected to remain mainly in the low to mid-70s for much of the state.
Clouds are expected to increase as the weekend progresses, with rain chances rising Sunday as the remnants of Isaias approach.
Sunday into Monday
The latest forecast suggests Sunday could start relatively quiet before conditions deteriorate later in the day.
Rain is expected to become more widespread Sunday, with periods of heavier rainfall possible Sunday night. The system could continue into Monday before moving away from the region.
Forecasters are continuing to monitor the storm because its eventual track and timing will determine how much rain New Jersey receives and where the heaviest precipitation develops.
Residents should keep an eye on updated forecasts over the next several days as meteorologists get a better understanding of the storm’s path.
For the Jersey Shore, the latest guidance also suggests that rain and potentially gusty conditions could develop Sunday into Monday, with marine conditions potentially becoming more hazardous during the passage of the system. Stay up-to-date with your local weather forecast.
