 As Gert was several days away from Bermuda , the NHC advised residents there to monitor the progress of the storm , Due to uncertainties in the future forecast , as well as the size and strength of Gert , a tropical storm warning and hurricane watch was issued for the island on September 19 , about two days prior to its closest approach . As Gert moved closer to the island , the watch and warning were replaced by a hurricane warning on September 20 , which was maintained until the following day after Gert moved further away . Before Gert passed by the island , officials closed two schools and converted them to emergency shelters . Police workers advised 700 families to leave their houses . Cruise lines diverted ships away , while hundreds of tourists took flights to leave the island .
