A hurricane blew through the NJ-Philadelphia region in 1818, and surprisingly got only this small write-up in the local paper: from the New Jersey Mirror 9 Dec 1818 A violent gale from the southwest commenced about 10 o'clock last Saturday evening and continued with little intermission until Sunday morning at sunrise. The damage to the port of Philadelphia was extensive. Nothing this severe has been experienced for twenty years. So a storm not seen in 20 years causes extensive damage---and this is the news? Likely it wasn't actually a hurricane---the official list of hurricanes for that year does not mention one in December.
