{{storm path|Carlotta 2018 track.png|alt=Map plotting the track and the intensity of the storm, according to the Saffir–Simpson scale}}

Tropical Storm Carlotta formed as the result of a breakdown in the Intertropical Convergence Zone to the south of Mexico. A tropical wave that traversed Central America around June 11 may have contributed to the storm's formation as well.{{cite report |last1=Pasch |first1=Richard |title=Tropical Cyclone Report: Tropical Storm Carlotta (2018) |url=https://www.nhc.noaa.gov/data/tcr/EP042018_Carlotta.pdf |publisher=National Hurricane Center |date=19 December 2018 |access-date=28 February 2019 |archive-url=https://web.archive.org/web/20190302090556/https://www.nhc.noaa.gov/data/tcr/EP042018_Carlotta.pdf |archive-date=2 March 2019 |url-status=live }} On June 12, the Miami-based National Hurricane Center (NHC) reported that a broad area of low pressure had formed several hundred miles south of southeastern Mexico.{{cite report |last1=Blake |first1=Eric |title=Eastern Pacific Tropical Weather Outlook [1100 AM PDT Tue Jun 12 2018] |url=https://www.nhc.noaa.gov/archive/xgtwo/gtwo_archive.php?current_issuance=201806122051&basin=epac&fdays=5 |publisher=National Hurricane Center |date=12 June 2018 |access-date=10 March 2019 |archive-url=https://web.archive.org/web/20200225010730/https://www.nhc.noaa.gov/archive/xgtwo/gtwo_archive.php?current_issuance=201806122051&basin=epac&fdays=5 |archive-date=25 February 2020 |url-status=live|series=NHC Graphical Outlook Archive }} The NHC continued to monitor the disturbance over the next two days as it drifted northward.{{cite report |last1=Blake |first1=Eric |title=Eastern Pacific Tropical Weather Outlook [500 AM PDT Thu Jun 14 2018] |url=https://www.nhc.noaa.gov/archive/xgtwo/gtwo_archive.php?current_issuance=201806141454&basin=epac&fdays=5 |publisher=National Hurricane Center |date=14 June 2018 |access-date=10 March 2019 |archive-url=https://web.archive.org/web/20190401192130/https://www.nhc.noaa.gov/archive/xgtwo/gtwo_archive.php?current_issuance=201806141454&basin=epac&fdays=5 |archive-date=1 April 2019 |url-status=live|series=NHC Graphical Outlook Archive }} Initially, strong upper-level winds prevented development, but the system increased in organization unexpectedly on June 14.{{cite report |last1=Blake |first1=Eric |title=Eastern Pacific Tropical Weather Outlook [1100 AM PDT Wed Jun 13 2018] |url=https://www.nhc.noaa.gov/archive/xgtwo/gtwo_archive.php?current_issuance=201806132034&basin=epac&fdays=5 |publisher=National Hurricane Center |date=13 June 2018 |access-date=10 March 2019 |archive-url=https://web.archive.org/web/20190401194933/https://www.nhc.noaa.gov/archive/xgtwo/gtwo_archive.php?current_issuance=201806132034&basin=epac&fdays=5 |archive-date=1 April 2019 |url-status=live|series=NHC Graphical Outlook Archive }} Following further structural improvements, the NHC upgraded the system to tropical depression status at 18:00 UTC while it was located about 140 mi (220 km) south of Acapulco.
