tropical produced scattered areas heavy rainfall mexico october caused significant flooding dissipated october month half official end season november storms hurricane adrian broad area low pressure developed tropical depression utc june situated miles southeast acapulco guerrero moving west northwestward depression intensified tropical storm adrian hours later favorable levels wind shear warm sea surface temperatures caused storm strengthen early june adrian intensified hurricane located miles south southeast southern tip baja california hours later adrian reached peak intensity winds mph minimum barometric pressure mbar inhg reaching peak intensity june adrian began weakening colder higher wind shear adrian fell tropical storm status late june weakened tropical depression june hours later utc adrian degenerated low clouds situated southwest southern tip baja california heavy rainfall produced storm caused minor flooding mexico fatalities directly attributed floods person listed missing people killed drowned rough seas produced offshore mexican coastline damage estimate heavy rainfall rough seas associated hurricane hurricane tropical wave developed utc july situated roughly south mexico time depression environment strong upper outflow resulting gradual intensification depression upgraded tropical storm utc july steady strengthened continued hours later category situated roughly miles south southwest moving westward southern periphery ridge north continued intensify defined eye visible satellite imagery early july microwave imagery hours later revealed likely undergoing eyewall replacement cycle complete utc intensification occurred major hurricane season utc july utc following day hurricane attained peak intensity winds mph minimum barometric pressure

tropical depression utc day utc july degenerated clouds tropical depression tropical wave moved atlantic caribbean early july crossing central_america july july system produced gusty winds heavy rainfall especially honduras nicaragua mexico precipitation reached inches veracruz july wave associated low pressure area emerged pacific_ocean system organized developed tropical depression utc july located miles west southwest mexico initially headed west northwestward july curved west southwestward depression failed strengthen dissipated utc july located miles southwest cabo mexico tropical depression july tropical wave entered eastern pacific_ocean following days slow organization occurred estimated system developed tropical depression utc july later day depression reached peak intensity maximum sustained winds mph minimum barometric pressure mbar inhg having failed reach tropical storm status moving westward depression entered area responsibility july time depression disorganized dissipated early following day tropical storm tropical wave crossed atlantic_ocean caribbean_sea early mid july later month wave acquired low level circulation tropical depression developed utc july situated miles south southwest organization satellite imagery depression upgraded tropical storm hours later wind shear exposed low level circulation halted intensification continued west northwestward cyclone according satellite classifications estimated weakened tropical depression utc july convective burst late july storm strengthen time turned northwestward response mid trough burst convection persist depression dissipated utc july located west southwest baja california low cloud remained subsequently continued west northwesterly course days tropical depression tropical wave previously crossed atlantic_ocean caribbean_sea reached eastern pacific basin late july system developed surface circulation july microwave imagery data indicated wind speeds mph result estimated tropical depression developed utc located nearly miles west southwest southern tip baja california miles southwest tropical depression depression moved west northwest encountered strong vertical wind shear despite convective bursts depression remained weak degenerated low clouds utc july hurricane tropical wave moved africa july crossed atlantic_ocean development wave quickly increased organization entering august designated tropical depression seven august depression strengthened tropical storm later day continued intensify despite upper level wind shear hurricane august shortly hurricane moved westward favorable environment began intensify quickly reaching category strength august maintained intensity days moved west weakened category strength entered area responsibility august briefly category passed south hawaii august began weakening final time passed south august produced large waves wind gusts mph hawaii heavy surf forced closure beaches hiking trails districts august crossed international date line shortly weakening tropical storm vertical wind shear strengthen western storm weakened fell tropical depression intensity early august dissipated late following day situated miles east hurricane eugene tropical wave crossed central_america july july entering pacific_ocean slowly organizing cloud pattern consolidated estimated tropical depression developed utc august located miles southwest cabo mexico hours later depression upgraded tropical storm eugene continued reaching hurricane status late august hours later eugene peaked strong category hurricane winds mph storm began weaken downgraded category hurricane early august eugene continued westward august entered area responsibility continued weaken downgraded tropical storm early august eugene passed south august minimal impact noted minor surf occurred east southeast shores additionally hour rainfall totals sections near inches storm weakened tropical depression late august utc august eugene dissipated located miles southeast tropical depression tropical wave moved african coast july entered pacific_ocean august system continued westward development august convection began increase utc august national_hurricane_center began classifying system tropical depression easterly wind shear depression intensify moved generally west northwesterly track depression dissipated august tropical storm tropical wave developed tropical depression utc august located miles south southwest mexico depression intensified gradually favorable conditions utc august cyclone upgraded tropical storm centered miles southwest storm continued slowly strengthened utc august attained peak intensity maximum sustained winds mph minimum barometric pressure mbar inhg time peak intensity august curved west southwest track motion persisted remainder duration track carried storm warmer increasing easterly wind shear caused weaken early august weakened tropical depression weakening slightly storm degenerated remnant low cloud utc august remnants persisted finally losing identity miles west southwest august tropical depression tropical wave entered eastern pacific august formed surface low pressure area south mexico august consolidating organizing somewhat system tropical depression late august colder caused convection diminish immediately moving parallel southern coast baja california thunderstorm activity slowly decreased cool utc august depression dissipated west tip baja california having lasted hours highest rainfall

september system emerged pacific_ocean began organize utc september tropical depression developed near mexico hours later depression strengthened tropical storm intensification occurred late september upgraded hurricane winds reached mph weakened tropical storm september approaching baja california utc day landfall near cabo storm curved westward weakened colder dissipating late september predecessor disturbance brought heavy rain mexico highest report inches precipitation caused flooding states severe flooding killed people addition people rendered homeless affected way remnants produced thunderstorms california particularly result widespread power outages isolated damage houses vehicles causing small overall damage relatively limited hurricane tropical wave moved coast
