Tropical Storm Track Service 2013-01-04T12:30:43-06:00 Tropical Storm Track Service 2013-01-04T12:30:43-06:00 Our tropical storm database is a distillation of the HURDAT data, available from the National Hurricane Center (NHC). The NHC post-analyzes the storm data for a year and updates the files in March or April of the following year. At that point we download the HURDAT files and load them into our database. During hurricane season (roughly April through January) we also monitor the NHC web site for ongoing storms. These are loaded into the database as soon as possible, but there is generally a 6-12 hour delay from the time of observation until the information is loaded into our database. Please note that we reprocess the HURDAT data for the previous storm season when it becomes available. This may change the information collected during the storm season: Storms may be added, deleted, renamed, or (most often) renumbered. Furthermore, note that the NHC is free to modify or augment the storm track data while a storm is ongoing, so the track data for a storm may change. We are currently storing the storms for two basins, Atlantic and (Northern) Eastern Pacific. The Atlantic storm data go back to 1851, and the Eastern Pacific data go back to 1949. Once the stormid of the desired storm is obtained, it is possible to retrieve the track information for the storm. The storm track service may be invoked as a SOAP service (XML input and XML output) or using a REST-like interface (HTML input and XML output). This service may be called using one of two methods: Either by specifying the stormid (yyyynnb) or by specifying the year and the name of the storm. One or the other must be specified. The presence of a stormid value overrides any year or name specifications. REST The REST-like interface uses HTML GET protocol to specify the search parameters: [?name=storm name&year=yyyy] [?stormid=yyyynnb] Either a storm name and a year or a stormid must be specified. For example, fetches the storm track for the storm identified as 2005111 (eleventh storm in 2005 in the Atlantic basin). name The exact name of the storm desired. Wildcards are not permitted. If "name" is specified , "year" must also be specified. year The year (yyyy) of the storm. If "year" is specified , then "name" must also be specified. stormid The internal storm-id of the storm , as returned by the Storm Search service , described above. This has the format yyyynnb , where yyyy is the year , nn is the chronological storm number , and b is the basin indicator (1 for Atlantic , 2 for Eastern Pacific). If the stormid is specified , any "name" or "year" values are ignored.
