The first tornado touchdown was in Staten Island at approximately
6:22 am in the vicinity of St. Austins Place in the Livingston-Randall Manor area. The tornado moved east, with additional damage occurring in the Tompkinsville area. Most of the damage in Staten Island was to trees, and estimated at EF-1 on the Enhanced Fujita Scale, with winds of 86 to 100 mph.
Based on re-analysis of radar data, the Staten Island tornado apparently dissipated as a second circulation developed just north of the first circulation. The damage in Tompkinsville may be a result of this second circulation.
