A slow moving low pressure system and a deep southerly flow from the Gulf of Mexico and then the Atlantic Ocean dropped heavy rain across New Jersey centered on April 30th. Event precipitation totals averaged from 3 to 6 inches, with the highest amounts in central New Jersey. This caused widespread poor drainage flooding as well as flooding of creeks and rivers throughout most of the state. Flooding in parts of the Passaic Basin and southeast New Jersey did not start until May began. Major creek and river flooding occurred in the Raritan and Assunpink Basins with moderate river flooding occurring in parts of the Passaic Basin. Many roadways were flooded. New Jersey Transit cross honored tickets on the commuter rail lines and buses. One hundred forty-six major roadways and interstates were flooded and completely closed or had lane closures throughout the state of New Jersey. Many roadways were re-opened by the end of the day on May 1st and most were opened again on May 2nd. The steady rain started during the afternoon of April 29th and fell at a steady light to moderate clip through the night. But, on April 30th the rain fell heavy at times during the morning and afternoon in the southern third of the state, and from the late morning into the evening of April 30th elsewhere in the state. Rainfall amounts of 2 inches in six hours were common. The rain ended from the south to north from around Midnight EDT to around 6 a.m. EDT on May 1st.
The heavy rain was caused by the combination of a strong high pressure system that built over the Canadian Maritimes that initiated the onshore flow and a strong, but slow moving low pressure system. The low pressure system was located in northwest Missouri on the morning of April 29th. It moved northeast to near Chicago during the afternoon of April 29th. The low pressure system then became nearly stationary in southern Wisconsin as its cold front reached Ohio early on April 30th. Then a new low pressure system developed on the frontal boundary and was over Eastern Tennessee on the morning of April 30th. The low pressure system reached West Virginia during the late afternoon on April 30th as its warm front started to move through Delmarva. The low pressure system reached north central Maryland at 11 p.m. EDT on April 30th as its warm front reached extreme southeast Pennsylvania and central New Jersey. The low pressure system reached the Allentown, Pennsylvania area at 5 a.m. EDT on May 1st and then was absorbed again into the frontal boundary associated with the original low as it moved into New York State that morning. The steady rain ended as the low pressure system passed north of New Jersey. But the formation of the second low pressure system and the passage of the warm front helped veer the winds from the east to the southeast and enhanced the surface flow that produced the coastal flooding along the tidal Delaware River.
