Abstract
In 1958 Atlantic Coastal radars performed a historic feat by continuously tracking two hurricanes—Daisy and Helene—for 500 nautical miles. The manner of accomplishment is discussed for each. The use of logarithmic spiral overlays on the radar PPI scope to locate the eye of Daisy is illustrated. Photographs are presented showing hurricane Helene as it appeared on the WSR-1 radar at Charleston, S.C., and on the more powerful SP-1M at Cape Hatteras, N.C. Personal observations of the author, who operated the SP-1M radar at the Weather Bureau Office, Cape Hatteras, with another radar meteorologist, during the passage of the hurricanes, are presented.
