Pre-ONI 3FL impact Cross-Peninsula Track Major Hurricane (Cat 3+) Needs manual review

Formed: 1871-08-14
Dissipated: 1871-08-23
Peak wind: 100 kt
Lifetime category: 3
Min pressure: 952 mb (lifetime)
Florida date: 1871-08-17
Approach: atlantic
FL regions: SE3 NE1 NW1
Center landfall: yes (1)
ENSO (ASO ONI): pre-1950, no ONI
Peak surge (FL): none exists for this era

Surge: no curated record, and none is likely to exist. Reliable landfall-zone surge observation generally predates neither the modern gauge network nor NHC Tropical Cyclone Reports for storms of this era; surge comparisons on this site skew modern as a result (disclosed on the methodology page).
