SULLIVAN COUNTY — Spring of 2025 has been a wet one in Sullivan County and the rain has thwarted many a backyard party as weekend plans have been regularly uprooted by the persistent precipitation. 

It’s been reported that some areas across upstate New York, including Syracuse, Albany, and parts of the Adirondacks haven’t had a dry weekend in six months. 

“It has definitely been a very wet end of winter and spring,” National Weather Service (NWS) Meteorologist Jake Chalupsky said. 

Chalupsky said his collaborative network of observers near Sullivan County reported wet weekends all the way back through the middle of March (NWS doesn’t have an official observation station in Sullivan County). 

Using official observation station data from three surrounding locations, Chalupsky was able to outline the following precipitation (in inches) from January 1 through June 11:

Binghamton, NY: 18.75’’ of precipitation; 17” inches is the normal average (1.75” above average)

Avoca, PA: 17.43” of precipitation; 15.18” is the normal average (2.25” above average)

Pine Bush, NY: 23.75” of precipitation; 19” is the normal average (4.75” above average)

Over the 2025 spring season (March, April, May is known as “meteorological spring”), Chalupsky said Avoca, Pa, had a total of 12.42” of precipitation, which represents the fourth highest total for the last 30 years. 

“It’s definitely been a wet spring but we were actually wetter last year;” he said; Avoca, PA had 18.99” and Binghamton had 20.65” by this time last year. 

Not only is total precipitation higher than normal, but the prevalence of single-day flash floods has increased. The United States Environmental Protection Agency said, “In recent years, a larger percentage of precipitation has come in the form of intense single-day events. The prevalence of extreme single-day precipitation events remained steady between 1910 and the 1980s but has risen substantially since then. Nationwide, Nine of the top 10 years for extreme one-day precipitation events have occurred since 1995. The occurrence of abnormally high annual precipitation totals has also increased.”
