New Jersey had a rainy spring, a rainy summer and a rainy start to autumn. As if that wasn't enough moisture and misery, more rain is on the way Tuesday and Wednesday, as two fronts move through, setting off bouts of heavy downpours and scattered thunderstorms with potentially damaging winds, according to weather forecasters.
One batch of rain is expected to move across the Garden State on Tuesday morning, thanks to a warm front that is lifting up through our region, said Valerie Meola, a meteorologist at the National Weather Service's forecast office in Mount Holly. After that, a cold front will be moving through on Wednesday, boosting the potential for strong thunderstorms and localized flooding.
Most of New Jersey has a slight to marginal risk of severe thunderstorms on Wednesday, according to forecast maps from the weather service's Storm Prediction Center.
“Heavy rain leading to localized flooding, especially in poor drainage areas, is possible Tuesday,” the weather service said in a hazardous weather outlook. “Thunderstorms with damaging winds and heavy rain are possible Wednesday.”

A very rainy 2018
If you hate rain, like most of us do, then 2018 has been a lousy year. Some parts of New Jersey have already gotten more rain in the first nine months of 2018 than they normally get during an entire year, according to data from the National Weather Service.
Atlantic City International Airport in Pomona, the weather service’s main climate station in South Jersey, has collected more than 44 inches of precipitation (rain plus melted snow) so far this year. That’s about 2 inches more than the historical annual average of 41.75 inches.
“We still have about 100 days to go,” Meola noted. And a rainy stretch of weather to deal with this week.
Other rainfall totals
With a heavy soaking this past weekend, Philadelphia surpassed its normal annual rainfall total of 41.53 inches as of late Sunday night, the weather service said.
Trenton and Newark have not yet reached their annual rainfall averages but are on pace to do that. Trenton has had 42 inches of precipitation so far this year, about 4 inches short of its normal annual total, while Newark has had 38.5 inches, about 8 inches away from its full yearly average.
Wet September in parts of N.J.
So far, September has been a very rainy month across the southern half of New Jersey. As of Monday morning, Atlantic City recorded close to 8 inches of rain this month.
If the city gets one more inch this week, its September total will be nearly three times higher than its normal monthly average of 3.15 inches.

2 tropical disturbances in the Atlantic
Forecasters from the National Hurricane Center are keeping an eye on two tropical disturbances in the Atlantic hurricane basin.
One disturbance is a broad area of disorganized showers and thunderstorms about 300 miles south-southeast of Cape Hatteras, North Carolina. Forecasters say the system has a 50 percent chance of developing into a tropical disturbance during the next two days.
“Environmental conditions are expected to become slightly more conducive for development during the next day or so while the system moves west-northwestward to northwestward,” the hurricane center said late Monday night. “By Tuesday night and Wednesday, upper-level winds are expected to increase, limiting chances for additional development, while the system moves northward near the southeastern United States coast.”
Another tropical wave — the remnants of Tropical Depression Kirk — is located about 1,100 miles east of the Windward Islands and heading west towards the Caribbean Sea. Forecasters say it has a 60 percent chance of redeveloping into a tropical depression in the next two days.
Meanwhile, Subtropical Storm Leslie is far out in the tropical Atlantic and heading east, posing no threat to land.
Coastal flood advisories
Coastal flood advisories are in effect until 2 p.m. Tuesday in coastal areas of Middlesex, Monmouth and Ocean counties and also in Atlantic, Cape May and Cumberland. The National Weather Service said minor coastal flooding is expected during Tuesday's high tide cycle.
"Up to one foot of saltwater inundation above ground level is possible in low-lying areas near shorelines and tidal waterways," the advisory says. "Minor roadway flooding is possible on Long Beach Island, Seaside Heights, Point Pleasant Beach and other locations near Barnegat Bay."
In addition, minor roadway flooding is possible for coastal locations in Monmouth County, and minor road flooding is possible in the Middlesex County towns of Old Bridge, Perth Amboy, South Amboy and Woodbridge.
