Tri-State Area – Heavy rain could cause flooding across parts of the Tri-State Area on Wednesday and Thursday, with a First Alert Weather Day in effect. The rain, expected to intensify as the day progresses, may cause flash flooding, while Hurricane Erin could bring indirect coastal impacts on Thursday.
Rain Begins Wednesday Afternoon, Risk of Flash Flooding
While the weather has been relatively calm at the start of the week, conditions are expected to worsen quickly. First Alert Weather forecasts light showers and drizzle in the morning hours on Wednesday, but by afternoon, heavy rain will already be underway in the northern suburbs. This heavy rain is expected to expand and intensify in the evening, continuing through Wednesday night into early Thursday morning.
“Rainfall rates could approach 1 inch per hour, which brings the imminent risk of flash flooding,” according to the National Weather Service.
Below-Average Temperatures and Coastal Impacts from Hurricane Erin
Temperatures on Wednesday will remain below average, reaching only the low 70s. After the rain tapers off by late Thursday morning, final rainfall totals could range from 1 to 2 inches, with some locations seeing locally higher amounts.
Meanwhile, Hurricane Erin will be positioned 350 to 450 miles offshore on Thursday. While no direct impacts are expected, indirect effects are likely, including dangerous rip currents, high surf, and coastal flooding.
The National Hurricane Center has warned that coastal flooding could result in 1-2 feet of inundation along the affected areas.
Coastal Impacts from Hurricane Erin
- Jersey Shore: Expect wind gusts of 35-45 mph, with surf as high as 13 feet and dangerous rip currents. Coastal flooding and beach erosion are possible.
- Long Island: Winds gusting between 35-50 mph, surf up to 15 feet, and coastal flooding are expected.
- NYC: Winds gusting up to 40 mph, surf 8-13 feet, and coastal impacts, including rip currents and beach erosion.
- Hudson Valley, Northern and Central New Jersey, Connecticut: Cloudy skies and gusty winds (25-35 mph) are expected, but these areas will see less of an impact.
