Hurricane Carlos was an unusually small tropical cyclone which affected the western coast of Mexico in June 2015. Forming as the third named storm and hurricane of the annual hurricane season, Carlos developed from a trough first noted by the National Hurricane Center on June 7. The disturbance gradually organized and was designated as a tropical depression three days later while south of the Mexican Pacific coast. Drifting slowly northwestward, the depression was upgraded further to a tropical storm. Although persistent wind shear and dry air hampered intensification early on, Carlos strengthened into a hurricane on June 13 after moving into a more favorable environment. However, the return of dry air and upwelling of cooler waters caused the system to deteriorate into a tropical storm. Paralleling the Mexican coast, Carlos later regained hurricane intensity on June 15 and attained peak winds of 90 mph (140 km/h) a day later. The reprieve was brief, however, as the onset of wind shear, land interaction, and dry air afterward led to rapid weakening. On June 17, Carlos degenerated into a remnant area of low pressure, having made landfall in Jalisco earlier that day. By the morning of June 18, Carlos was declared to have completely dissipated. Category 1 hurricane: peak winds of 90 mph (80 knots), lowest pressure 978 mb. June 10 – June 18, 2015. Landfall: June 17 at 50 mph, 19.3°N 104.9°W. Accumulated cyclone energy: 9.4.
