This project is part of an ongoing effort to correct errors and biases within the National Hurricane Center’s North Atlantic best track and intensity hurricane database, HURDAT, from 1851 to the present. The Comprehensive Ocean Atmosphere Data Set (COADS) contains historical weather observations from ship reports and data buoy records. These reports, cross referenced with historical weather maps, newspaper articles and written accounts, can alter the known best track and intensity files by offering a better, more accurate, understanding of landfalling tropical cyclones from 1935 to 1939. Special attention will be given during the re-assessment of significant hurricanes of the period such as the 1935 Labor Day hurricane that hit the Florida Keys and the 1938 New England hurricane.
