 Shortly after 1700 UTC on September 22, the eye of Janet passed over Barbados. A reconnaissance flight into the hurricane discovered that the Hurricane Janet's eye measured only 20 mi (32 km) in diameter, with gale force winds extending 120 mi (190 km) away from the center of circulation. The flight also reported a minimum barometric pressure of 979 mbar (hPa; 28.91 inHg). After passing between the islands of Grenada and Carriacou in the morning hours of September 23, Janet entered an area of unfavorable conditions in the eastern Caribbean Sea. As a result, the hurricane became disorganized, with winds weakening to 90 mph (145 km / h) by 1200 UTC on September 23. A U.S. Navy reconnaissance plane entered the hurricane early on September 24, reporting a lack of organization, and noting an indiscernible center of circulation with weak rainbands. However, the hurricane began to reintensify in favorable conditions, regaining major hurricane strength by 1200 UTC on September 24 and subsequently Category 4 hurricane intensity by the next day.
