Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.

Advisories are issued for storms that have attained at least tropical depression status, and are issued every 6 hours, at 0000, 0600, 1200, and 1800 hours. Tropical Prediction Center/National Hurricane Center advisories are discontinued once a storm makes landfall and all storm warnings are dropped, or when the wind speed drops below 30 knots or 35 mph. The records for each date are listed in order. NOAA MONTH The month of the storm advisory. Advisories are issued for storms that have attained at least tropical depression status, and are issued every 6 hours, at 0000, 0600, 1200, and 1800 hours.

The records for each date are listed in order. NOAA DAY The day of the storm advisory. Advisories are issued for storms that have attained at least tropical depression status, and are issued every 6 hours, at 0000, 0600, 1200, and 1800 hours. Tropical Prediction Center/National Hurricane Center advisories are discontinued once a storm makes landfall and all storm warnings are dropped, or when the wind speed drops below 30 knots or 35 mph. The records for each date are listed in order. NOAA AD_TIME The storm advisory time. Times are in Zulu (a.k.a., Universal Time-UTC, Greenwich Mean Time-GMT) starting with 0000Z and ending with 1800Z. NOAA BTID The unique event identifier. Identifiers are sequential, starting with 1 in June, 1851 and ending with 1320 in December, 2004. NOAA FGDLAQDATE Date FGDL aquired the data from source. GeoPlan NAME The given name of a storm. Storms are named if they are true tropical storms and attain a sustained wind speed of at least 39 mph. NOAA NOT NAMED There is no given name for the storm. Prior to 1950 storms were not named. SUBTROP There is no given name for the storm because it was classified as a subtropical depression or subtropical storm. SUBTROP1 There is no given name for the storm because it was classified as a subtropical depression or subtropical storm. Subtrop1 is the first subtropical cyclone for a given year. A storm may initially be identified as Subtrop1 but then be given a name if it develops into a tropical storm; in this case there will be no storm identified as Subtrop1 for the year even though there may be a storm identified as Subtrop2. SUBTROP2 There is no given name for the storm because it was classified as a subtropical depression or subtropical storm. Subtrop2 is the second subtropical cyclone for a given year. A storm may initially be identified as Subtrop2 but then be given a name if it develops into a tropical storm; in this case there will be no storm identified as Subtrop2 for the year even though there may be a storm identified as Subtrop3. SUBTROP3 There is no given name for the storm because it was classified as a subtropical depression or subtropical storm. Subtrop3 is the third subtropical cyclone for a given year. A storm may initially be identified as Subtrop3 but then be given a name if it develops into a tropical storm; in this case there will be no storm identified as Subtrop3 for the year even though there may be a storm identified as Subtrop4. SUBTROP4 There is no given name for the storm because it was classified as a subtropical depression or subtropical storm. Subtrop4 is the fourth subtropical cyclone for a given year. A storm may initially be identified as Subtrop4 but then be given a name if it develops into a tropical storm; in this case there will be no storm identified as Subtrop4 for the year. UNNAMED Storms from 1950 or later may be unnamed if they were not recognized as tropical storms or hurricanes at the time of their occurrence. LAT The latitude measurement of the storm's center, in tenths of decimal degrees. NOAA WIND_KTS The measured or estimated windspeed at the time of the advisory, in whole knots. NOAA PRESSURE The measured or estimated barometric pressure at the time of the advisory, in millibars. A value of 0 indicates the barometric pressure is unknown. NOAA CAT The intensity classification of the storm. Hurricanes are classified according to the Saffir-Simpson Hurricane Scale. NOAA D The storm was classified as a tropical disturbance at the time of the advisory. A tropical disturbance is a discrete tropical weather system of apparently organized convection (i.e. thunderstorm activity), which is generally 100 to 300 nautical miles in diameter. It originates in the tropics or subtropics, has a nonfrontal migratory character, and maintains its identity for 24 hours or more. It does not necessarily exhibit circulation, but may develop into a tropical cyclone. E The storm was classified as Extratropical at the time of the advisory. Extratropical is a term used in advisories and tropical summaries to indicate that a cyclone has lost its tropical characteristics. The term implies both that the cyclone has moved out of the tropics and that the energy source driving the storm has changed. While tropical cyclones derive their energy from the convection of warm, moist air, extratropical storms derive their energy from the temperature contrast between warm and cold air masses. It is important to note that cyclones can become extratropical and still retain winds of hurricane or tropical storm force. H1 The storm was classified as a Category 1 hurricane at the time of the advisory. A Category 1 hurricane is a tropical cyclone with maximum sustained surface (10 meter) winds of 64 knots/74 mph to 82 knots/95 mph, inclusive. H2 The storm was classified as a Category 2 hurricane at the time of the advisory . A Category 2 hurricane is a tropical cyclone with maximum sustained surface (10 meter) winds of 83 knots/96 mph to 95 knots/110 mph, inclusive. H3 The storm was classified as a Category 3 hurricane at the time of the advisory. A Category 3 hurricane is a tropical cyclone with maximum sustained surface (10 meter) winds of 96 knots/111 mph to 113 knots/130 mph, inclusive. H4 The storm was classified as a Category 4 hurricane at the time of the advisory. A Category 4 hurricane is a tropical cyclone with maximum sustained surface (10 meter) winds of 114 knots/131 mph to 135 knots/155 mph, inclusive. H5 The storm was classified as a Category 5 hurricane at the time of the advisory. A Category 5 hurricane is a tropical cyclone with maximum sustained surface (10 meter) winds greater than 135 knots/ 155 mph. L The storm was classified as a tropical low at the time of the advisory. A tropical low indicates low pressure at the surface, but no other characteristics of a tropical cyclone are present. SD The storm was classified as a subtropical depression at the time of the advisory. A subtropical depression is a subtropical cyclone with maximum sustained surface (10 meter) winds of less than 34 knots/39 mph. SS The storm was classified as a subtropical storm at the time of the advisory. A subtropical storm is a subtropical cyclone with maximum sustained surface (10 meter) winds of 34 knots/39 mph or greater. TD The storm was classified as a tropical depression at the time of the advisory. A tropical depression is a tropical cyclone with maximum sustained surface (10 meter) winds of less than 34 knots/ 39 mph. TS The storm was classified as a tropical storm at the time of the advisory. A tropical storm is a tropical cyclone with maximum sustained surface (10 meter) winds of 34 knots/39 mph to 64 knots/73 mph, inclusive. W The storm was classified as a tropical wave at the time of the advisory. Tropical waves occur in the trade-wind easterlies, moving to the west with a wave-like motion. They show a detectable shift in wind direction, which may not be detectable at the surface but may be seen in the middle atmosphere. A tropical wave may develop into a tropical cyclone.
