atlantic_ocean caribbean_sea crossing central_america june emerging warm waters east pacific june shortly satellite imagery showed good upper level outflow cloud banding remained disorganized june broad circulation better organized northeastern section deep convection developing tropical depression formed later day miles southeast acapulco mexico developed moved northward southwest coast mexico organized sufficiently named tropical storm june cyclone drifted north northwest hours turning westward parallel mexican coast storm began lose convection june weakened tropical depression later day depression weakened weak low level circulation dissipating june approached acapulco area mexican coast landfall portion coast affected received heavy rainfall unofficial reports state person died result storm storm produced damage rainfall flooding tropical storm satellite imagery detected low level circulation june associated heavy convection miles south mexico guatemala border intensified tropical depression cyclone moved northwest west northwest days mph wind report ship june allowed depression upgraded tropical storm later day day low level circulation moved away deep convection dissipating near acapulco mexico portion remaining land reason lack strengthening cyclone tropical depression system developed eastern pacific later strengthened tropical depression july obtained better defined low level circulation center exposed little convection northeast shear aloft system moved northwest shear continued deep convection cyclone southwest center circulation circulation completely lacked deep convection late july continued defined low level center depression drifted slowly northward located south baja california dissipating south peninsula july circulation deep convection detected small associated rainfall affected baja california cyclone passed near peninsula tropical wave moved western coast africa june weeks moved tropical waters atlantic_ocean later crossed central_america began developing entered pacific_ocean dense area moisture wave developed disturbance july attained tropical depression status afternoon july south mexico entering favorable area warm waters depression strengthened july continued develop reached peak strength developed july duration storm considered hurricane post season strength upgraded minimal hurricane status moved favorable conditions lost strength weakened tropical storm july began lose deep convection weakened tropical depression july moved cooler waters later moved west southwest dissipated july tropical wave moved coast northwestern africa july moved tropical regions northern atlantic caribbean_sea indication development tropical disturbance crossed central_america july july westward motion decreased convection organization increased warm waters developed tropical depression july miles southwest southern tip baja california july high pressure system western united_states northern mexico forced daniel upper level low parallel west northwest paths daniel stayed generally strength days reaching peak strength july daniel declined tropical depression july dissipated july july tropical wave exited africa crossed atlantic_ocean crossed pacific_ocean july developing convection outflow july organized tropical depression southwest coast mexico continuing generally westward thunderstorm activity fluctuated slowly developing intensified july storm attained peak winds mph july wind shear interaction nearby tropical storm prevented intensification low level circulation located northwest edge deepest convection disorganized difficult locate satellite imagery soon circulation exposed thunderstorms august weakened tropical depression status late august advisory issued system disorganized minimal convection remnants tracked days deep convection returned momentarily system convection soon disappeared hurricane organized disturbance deep convection organized northeastern pacific_ocean july developed tropical depression later day miles southwest southern tip baja california position formation south west tropical cyclones form time period depression moved westward gradually strengthening developed tropical storm july intensified days intensified hurricane july system increased speed steadily strengthened trough turned storm west northwestward august satellite estimates indicated reached maximum intensity later august defined eye deep convection surrounding issued tropical storm watch august threatening west northwest turn retreat trough later turned west discontinued tropical storm watch august good upper level conditions later weakened began lose convection cooler waters quickly weakened weakened tropical storm later august depression august depression turned west northwestward august dissipated august cyclone moved near hawaiian islands heavy rainfall fell chain peaking near island hawaii tropical depression tropical depression developed eastern pacific july forecast absorbed close nearby depression later tropical storm depression moved northward unfavorable conditions cyclone weakened depression southwest strengthened limited deep convection developed system cyclone continued unfavorable conditions visible satellite imagery later showed weak system storm dissipated july wave previously moved atlantic northwest coast africa crossed central_america pacific july july july disturbance miles southeast developing system moved westward following week signs intensification july system appeared strengthening banding pattern july convection underwent organization weak outflow high storm developed tropical depression later july west east pacific storms develop day cyclone remained fairly stationary began strengthen warm waters july depression strengthened based satellite imagery limited intensification followed shear high storm weakened tropical depression july weakness depicted satellite imagery moved west northwestward northeast pacific depression dissipated near august direct damage deaths rainfall occurred islands hurricane tropical depression formed july miles south acapulco mexico depression tracked west
