Elizabeth (Newark Liberty International Airport)ĭan Zarrow is Chief Meteorologist for Townsquare Media New Jersey. Note: only four rainfall reports were received in Salem Countyĥ.72". Lumberton (South Jersey Regional Airport) Egg Harbor Twp (Atlantic City International Airport)Ĥ.87". They should be considered preliminary, unverified and unofficial.Ĥ.62". These totals were current as of 7:30 a.m. Data was pulled from the New Jersey Weather Network at Rutgers, CoCoRaHS, the CO-OP network of first-order weather stations, and Public Information Statements issued by the National Weather Service in Mt. These represent totals over three days: Friday 4/28, Saturday 4/29, and Sunday 4/30. I have compiled a "Top 5" rainfall totals for each of New Jersey's 21 counties, listed below. If temperatures were 30 degrees colder? Sure, it could have been an incredible one-two punch of blizzard conditions. The heavy rain was driven by "warm cloud" processes - such heavy precipitation would never occur in the kind of drier, colder air mass required for a winter storm. However, such a comparison is not really accurate or applicable. So 6" of rain would equal about 60" of snow. And the simple answer is to multiply total rainfall by 10, as the average snow-to-liquid ratio is 10:1. I am asked this question every time it rains a lot. In other words, there is less than a 10% annual chance of exceeding that amount of rain over the course of three calendar days. The state maximum 3-day total of 7.03" in Berkeley Township exceeds the 10-year storm estimate for that point, according to NOAA Atlas 14. This relates to some heavy-duty statistics used in engineering and design work. (Well, less than 72 hours.)Īnother way to think about extreme precipitation events is in terms of storm recurrence. More than a month's worth of rain in one weekend. Normal rainfall for the month of April is 3.87". That 3-day rainfall was more than EWR saw in the entire month of March and first 27 days of April, combined. The weather station at Newark Liberty International Airport (which is technically in Elizabeth, Union County) picked up 5.72" of rain.
The one-two punch of broad, strong storm systems was sufficient. Especially considering it did not come as a result of a tropical storm or a deep pool of high humidity. The state's top wind gust was 62 mph, recorded at Little Egg Harbor Township on Saturday. Both Salem and Warren counties saw rainfall totals in the 2-3" range, rather than half-a-foot. The driest corner of New Jersey this weekend was the western edge of the state, falling out of the heaviest rain bands. Statewide average rainfall was around four inches. The top rainfall total I could find in New Jersey was 7.03" at Berkeley Township, Ocean County.Įvery county in the state had at least one rainfall report over three inches. However, we do have more raindrops, unsettled weather, and unseasonably cool temperatures in the forecast. But as expected, the threat for "severe" weather (wind, hail, tornado) stayed well south of New Jersey.Īs we collect the final 72-hour rainfall data now, the sun is shining on Monday morning. Some coastal flooding was noted along back bays. There were flooding issues, especially Sunday, as heavy rain poured over saturated soil.
