Brandywine Creek’s previous crest record was 17.15 feet on Sept. The center noted that the normally tranquil Brandywine Creek at Chadds Ford, Pennsylvania, reached 21.04 feet, it’s all-time highest water level on record – as measurements go back well over 100 years. In a three-hour period, Newark saw 6.42 inches during the tempest, as that is estimated to be near the storm’s sole 1,000-year event. 1, was a 500-year storm event, while its 5.06 inches in two hours and 7.88 inches in six hours, on the same day, were also at least 500-year events, Borisoff said. Newark’s wettest hour, with 3.24 inches from 8 to 9 p.m. 1, which – on the month’s first day – made it the fourth wettest September on record. West of the city, across the Hudson River, Newark, New Jersey saw its all-time rainiest day with a total of 8.41 inches on Sept. ![]() Since the rain presented an imminent and significant threat to human life or property, flash flood emergency warnings were issued for the first time in New York City and northern New Jersey, Borisoff said. “Receiving over 3 inches of rainfall in an hour was indeed surprising, especially after receiving nearly 2 inches in an hour a week earlier.” 26, 1947, in association with a strong frontal system that crossed the region,” he said. “Records show the previous long-held hourly precipitation record at Central Park, of 2.83 inches, occurred on Aug. “While the total daily rainfall associated with Ida was not a big surprise, the rate at which it fell in a very short one- to six-hour period was astonishing,” DeGaetano said. ![]() LaGuardia Airport, in Queens, saw 6.8 inches of rain on Sept. Central Park’s two-hour rainfall of 4.65 inches and the six-hour of 6.63 inches both were 500-year storm events 1, Central Park in New York City, received 3.15 inches of rain as it fell from about 9 to about 10 p.m., their all-time rainiest hour, according to NRCC climatologist Samantha Borisoff, who compiled the climate data after the massive storm. “This is a very effective mechanism to transform the water vapor in the atmosphere into rainfall,” he said. “Such interactions between hurricane remnants and mid-latitude frontal boundaries, commonly produce heavy rainfall, as the very moist tropical air associated with the hurricane is forced to rise over cooler air associated with the frontal boundary. “What had been the center of Ida, tracked over parts of Pennsylvania, New Jersey, New York and Connecticut, which received the heaviest rainfall totals,” DeGaetano said. In addition to temperature and precipitation statistics, the group examines climatic variables for agricultural production, hydrology and environmental impacts. Since 1983, Cornell’s NRCC has been collecting and archiving climate data to assess weather impacts in the Northeast. DeGaetano, professor of earth and atmospheric sciences (CALS) and director of the NRCC. “The rainfall from Ida resulted from the merger of the remnants of Hurricane Ida (a tropical depression when it reached the Northeast) and a stationary front that was draped across New Jersey,” said Arthur T. The storm prompted rivers and creeks to overflow, spawned tornadoes, and qualified as exceeding 500-year and 1,000-year rainfall events, according to Cornell’s NOAA Northeast Regional Climate Center (NRCC), in the College of Agriculture and Life Sciences. Packed with an historically massive amount of tropical water, the remnants from Category 4 Hurricane Ida deluged eastern Pennsylvania, New Jersey and New York City with unmatched rainfall on Sept. ![]()
