Easy to Read HURDAT FormatAn easier to read version of the
HURDAT Atlantic Best Track data files were formulated by Chris Landsea
to aid researchers. The data layout is self-explanatory with headers included
for each column.

Next is a seperator line of asterisks '*'. Then there is another header line providing the information of each column of data to follow. The actual data follows with the date, time, position, maximum sustained wind direction and speed, central minimum pressure, and storm type. Time is given in Universal Time Code (UTC) which is a 24 hour clock rendering of the the time at 0 degrees Longitude or Greenwich Mean Time (to convert to Eastern Standard Time add five hours, to convert to Eastern Daylight Savings Time add four hours). Latitude and Longitude are to the nearest tenth of a degree and the Hemispheres are listed as 'N' or 'S' for North or South and 'E' or 'W' for East or West. Wind direction is degrees clockwise from due north (0 deg.). Wind speed is given in both miles per hour and kilometers per hour. The central minimum pressure is given in millibars. And storm type is either Tropical Disturbance, Tropical Depression, Tropical Storm, Hurricane, or Major Hurricane. If it is a Hurricane or Major Hurricane the Category on the Saffir-Simpson scale is then listed. Each 6 hour value is on a seperate ASCII line and the listing continues until the next storm listing begins as noted by the header line. |
