Isbell

La Nina 2FL impact Cross-Peninsula Track Major Hurricane (Cat 3+) Rapid Intensification

Formed: 1964-10-09
Dissipated: 1964-10-16
Peak wind: 100 kt
Lifetime category: 3
Min pressure: 964 mb (lifetime)
Florida date: 1964-10-14
Approach: gulf
FL regions: SW2 SE1
Center landfall: yes (1)
ENSO (ASO ONI): -0.76
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).
