DAILY DATA:
- Card# = As above.
- MM/DD = Month and Day
- Positions and intensities are at 00Z, 06Z, 12Z, 18Z
- & =
- '*' (tropical cyclone stage),
- 'S' (Subtropical stage)
- 'E' (extratropical stage)
- 'W' (wave stage - rarely used)
- 'L' (remanent Low stage - rarely used)
- Lat = Latitude of storm: 24.5N
- Long = Longitude of storm: 61.0W
- Wind = Maximum sustained (1 minute) surface
(10m) windspeed in knots (these are to the nearest 10 knots
for 1851 to 1885 and to the nearest 5 kt for 1886 onward).
- Press = Central surface pressure of storm in mb
(if available). Since 1979, central pressures are given
everytime even if a satellite estimation is needed.
TRAILER:
- Card# = As above.
- Tp = Maximum intensity of storm
- 'HR' = hurricane
- 'TS' = tropical storm
- 'SS' = subtropical storm
- Hit =
The impact of the hurricane on individual U.S. states ('LA'
= Louisiana, etc.) based upon the Saffir-Simpson Scale category
(through the estimate of the maximum sustained surface winds for
each state). See scale below. Occasionally,
a hurricane will cause a hurricane impact (estimated maximum sustained
surface winds) in an inland state. To differentiate these cases versus
coastal hurricane impacts, these inland hurricane strikes are denoted with
an "I" prefix before the state abbreviation. States that have been so
impacted at least once during this time period include Alabama (IAL),
Georgia (IGA), North Carolina (INC), Virginia (IVA), and Pennsylvania
(IPA).
The Florida peninsula, by the nature of its relatively landmass, is all
considered as coastal in this database.
Note that Florida and Texas are split
into smaller regions:
- 'AFL' = Northwest Florida
- 'BFL' = Southwest Florida
- 'CFL' = Southeast Florida
- 'DFL' = Northeast Florida
- 'ATX' = South Texas
- 'BTX' = Central Texas
- 'CTX' = North Texas
