Rain, rain, go away. Come again another day.

New Jerseyans have been humming that tune to no avail for what seems like all of 2018, a year that is poised to go down as one of the wettest in our state's recorded history.

The excessive rain has forced people from their homes, swept away cars and left the state more vulnerable to additional flooding from upcoming storms. It's also been the bane of farmers, who just a few years ago were lamenting drought conditions.

“It's hard to find a farmer that isn’t frustrated right now,” said Peter Furey, executive director of the New Jersey Farm Bureau.

Through September, the state's total precipitation count for the year — derived from a formula that uses measurements of snow and rain from individual stations — is 46.09 inches, or 32 percent above normal.

Rockaway, a wooded borough in Morris County, has logged 5 feet of rain in 2018 with three months still to go. Howell, Princeton and Bloomingdale have all had more days with rain or snow than without this year, according to weather station data.

The wettest year on record in New Jersey is 2011, when almost 64 inches of rain fell.

Even if 2018 returns to normal for the last three months, we're still on pace for the fifth dampest year since this data was first gathered 123 years ago.

“What we’re talking about is a year (2018) where it’s been a cumulative effect, not a few big shots," said David Robinson, a Rutgers professor and the state's official climatologist since 1991. "That’s not what made 2011 the wettest year on record. We (in 2011) had a major storm in March, (Hurricane) Irene in late August and some parts of the state even got some rain from (Tropical Storm) Lee a few weeks later.”

"The nickels and dimes have added up this year," he continued, "and in a few instances they’ve been far more than nickels and dimes."

You might recall the image of floating cars, unmoored from their parking spots in Little Falls during a torrential downpour — 4½ inches in less than an hour— on Aug. 11 that paralyzed parts of northern Jersey.

Just a couple days later, more than 200 homes in Brick were damaged, along with a couple dozen in Howell, by a deluge of rain on Aug. 13. Nearly 8 inches of rain fell in spots of northern Ocean and southeastern Monmouth County that morning.

"We have had nine different days since June where somebody — one of our observers — have measured at least 4 inches of rain," Robinson said.

The drought that took hold in 2015 has long ago disappeared in the rearview mirror.

Reservoirs across the state are universally as full as they've been in years. The city of Newark's five reservoirs are at capacity, 14.4 billion gallons of water in storage.

At this point, the rain that is falling is replenishing groundwater reserves. That's great for the reliability of the water supply, but it leaves us more vulnerable to flooding when we get these bursts of rain, Robinson said.

Episodes of residential flooding aside, the wet 2018 has been hardest on New Jersey's farmers.

However, the impact on the $1.1 billion agriculture industry in New Jersey is as varied as the crops it grows.

Nurseries, which represent the largest share of agriculture in the state, likely aren't bothered by the overabundance of rain, but other segments of farmers feel like they're drowning, said Furey, from the Farm Bureau.

“Take a crop like apples for example," Furey said. "When you have a lot of excess rain, those apples will size up and then they’ll drop from the tree before normal harvest. … Then you’re scrambling to bring that crop to market.”
