A compact storm set a rainfall record at Atlantic City International Airport on Sunday but was spared nearby | Local News


Rainfall at Atlantic City International Airport broke the county’s daily rainfall record on Sunday, but the deluge was so concentrated that most of you in the surrounding areas probably didn’t notice it.

The airport reported 3.52 inches of rain Sunday, breaking the old record of 2.81 inches of rain set in 1962, according to the National Weather Service. Sightings at the airport date back to 1943.

Not only that, but 3.25 inches of that rain fell between 12:54 p.m. and 1:54 p.m. This extreme amount of rain had roughly less than a 1% chance of occurring at the airport this year.

While this type of rainfall certainly helps eliminate drought issues, most of the region has barely seen a drop. Cape May, most of Cumberland and Atlantic County south of the airport remain in moderate drought according to the United States Drought Monitor.

According to the Community Collaborative Rain, Hail and Snow Network (CoCoRaHS), volunteer observation rain gauge sites at Absecon and Egg Harbor City collected just 0.01 and 0.02 inches of rain, respectively. CoCoRaHS is the largest voluntary observer network in the country and has been used to determine weather records.

Only the Hamilton Township CoCoRaHS gauge on the Egg Harbor side of Hamilton Township (2.26 inches), Port Republic (0.85 inches) and Estell Manor (0.45 inches) recorded appreciable rainfall in the County of Hamilton. Atlantic. No measurable rain fell from Cape May or along the coast to Point Pleasant in Ocean County. Hammonton also saw no rain.

While this uneven distribution of rainfall is common in the summer, this summer has seen extreme instances of isolated rainfall.

On August 22, the Ocean Acres section of Stafford Township, along with Surf City and Harvey Cedars all collected over 4.5 inches of rain in a historic heavy rain event. Harvey Cedars had a 0.1% annual chance of getting 2.16 inches of rain in 15 minutes, which they did. However, in Atlantic, Ocean, Cape May and Cumberland counties, only nine of approximately 55 CoCoRaHS sites collected more than half an inch of rain.

Events like this have led to a ‘feast or famine’ scenario this summer in New Jersey, where some 6.3 million residents live in drought, while the remaining 2.5 million residents are free from drought.

A review from July 30 to Aug. 28 of weather stations with continuous recordings across the state shows Atlantic City International Airport received the most precipitation in the state, with 4.25 inches of rain. That’s more than seven times the lowest.

Meanwhile, in Margate, just 0.58 inches of rain fell. The second and third lowest in the state are Sen. Frank S. Farley State Marina in Atlantic City and Ocean City.

Drought is usually cured by a widespread rain event or rain events. Between the second half of August and the first half of October, this is usually done by active or residual tropical systems.

However, with a very calm Atlantic hurricane season so far, this widespread rain has not arrived. As of August 29, only three named storms have formed. It’s two weeks late. On August 29, the sixth named storm of the hurricane season would have occurred. Danielle is the fourth named storm in the 2022 list.

That leaves New Jersey with the vagaries of weak cold fronts and pop-up thunderstorms in the summer to bring rain. Couple that with well below average water temperatures for much of July and early August, Atlantic City reported temperatures in the 50s at times, and the high moisture content needed for storms was not there. .
