upgraded tropical storm post storm analysis determined system attained tropical storm force winds peaking mph hours august hours later system disorganized increased wind shear afternoon august system weakened tropical depression shortly degenerated non convective remnant low pressure area failed maintain convection center hours time nhc issued final advisory system noted possibility regeneration august roughly hours remnant low convection began system later day hurricane hunter reconnaissance plane deployed system found system shortly nhc began issuing advisories depression located roughly east leeward_islands depression continued track westward response upper level high north atlantic early august nhc upgraded depression tropical storm giving deep convection developed center circulation later day wind shear caused convection displaced circulation exposing center august forward motion began increase storm quickly entered region dry stable air afternoon hurricane hunter reconnaissance mission find evidence tropical storm force winds resulting downgraded tropical depression determined post storm analysis degenerated tropical wave shortly longer tropical cyclone hours later system redeveloped convection raced west northwest mph early august radar imagery guadeloupe san_juan puerto_rico depicted system closed low level circulation despite nhc continued operational advisories confirmation visible satellite imagery later day final reconnaissance plane flew storm find low level circulation following nhc stated dissipated coast puerto_rico despite having degenerated tropical wave previous day remnants monitored signs regeneration land interaction hispaniola cuba system chances redevelopment preparations impact august tropical storm watch issued
