 In addition to the storms which attained at least tropical storm strength in 1940 , five additional tropical depressions were analyzed by the HURDAT reanalysis project to have developed during the season . Due to their weak intensity , however , they were not added to HURDAT . On September 2 , a closed low @-@ pressure area was detected in the open Atlantic Ocean southeast of Bermuda and was analyzed as a tropical depression . At the time , the disturbance had a minimum pressure of at least 1015 mbar ( hPa ; 29 @.@ 98 inHg ) . The depression initially moved to the southeast , but later recurved towards the northwest over the next two days . On September 4 , the S.S. West <unk> en route for Boston , Massachusetts reported winds of 40 mph ( 65 km / h ) , which would be considered as tropical storm @-@ force winds . The depression later moved to the northeast before it was absorbed by a stationary front on September 7 . Since there was only one report that the disturbance may have reached tropical storm intensity , it was not included in HURDAT . Later on September 10 , a trough was detected in a similar region in the Atlantic where the first depression formed . The trough later became sufficiently organized to be classified as a tropical depression . The cyclone moved slowly to the east and did not further intensify before dissipating on September 13 .
