Acid rain (Wikipedia Says: any form of precipitation that is unusually acidic, i.e. elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids.) would do it. Because of the sulfur content, you would notice the “bad egg” smell. It also could be causing flooding in Jersey, and the pressure system could be bringing their smell down towards you. Icky.
