1961: On September 10th, the Television Infrared Observation Satellite observed an area of thunderstorms west-southwest of the Cape Verde Islands, suggesting a possible tropical cyclone. This storm is the first large tropical cyclone to be discovered on satellite imagery and would eventually become Hurricane Esther. On September 20th, Hurricane Esther, a Category 4 storm off of Cape Hatteras, North Carolina began to slow down as it moved north-northeast well off the Jersey shore. The storm continued to weaken as it made a five-day loop south of Cape Cod, Massachusetts, then moved to Cape Cod and into Maine on the 26th.

Above is Tropical Cyclone Esther on September 10, 1961, two days before its existence was confirmed by aircraft reconnaissance. The image is courtesy of the Monthly Weather Review, published in 1961.
