Tropical Storm Colin was a weak and short-lived tropical storm that formed over the Carolinas. The third named storm of the 2022 Atlantic hurricane season, Colin originated from a tropical wave off the coast of Georgia. It was given the name Colin on July 2 at 9:00 UTC, 50 miles (80 km) southwest of Myrtle Beach.[1] It moved slowly northeast, causing isolated thunderstorms on South Carolina. It sustained its peak of winds up to 45 mph (65 kph), until rapidly weakening the next day while interacting with a upcoming cold front. One man died in North Carolina due to rip currents. The National Hurricane Center issued the last advisory of the storm during 02:00 UTC on July 3, 2022. Strong wind shear caused most of its heavy rain to remain offshore, exposing the bottom layer of the storm. The damages that were caused by the storm was minimal.

▲ Extratropical cyclone / Remnant low / Tropical disturbance / Monsoon depression

On July 1st, the National Hurricane Center started monitoring a low-pressure area off the coast near Savannah, Georgia at 09:00 UTC. The system began to rapidly organize and by 12:00 UTC on July 2nd, it had unexpectedly formed into a tropical storm just 25 miles west-southwest of Myrtle Beach, South Carolina, and it was given the name Colin.[2] Colin's wind speeds did not strengthen as it moved north towards North Carolina and stayed at it's peak intensity of 45 mph (72 km/h).[3] Later that day, a tropical storm warning was issued for many areas of North and South Carolina, including South Santee River to Duck, North Carolina.[4] By 03:00 UTC, Colin's winds decreased to 35 mph (62 km/h) and were subsequently downgraded into a tropical depression.[5] It continued weaken rapidly, while interacting with a cold front. By 02:00 UTC on July 3, 2022, the National Hurricane Center has issued its last advisory of the storm, as it moved offshore of North Carolina.[6][7]

Preparations and impact

Map of rainfall produced by Tropical Storm Colin across the Southeastern United States

Upon formation, a Tropical Storm Warning was issued from the South Santee River in South Carolina to Duck, North Carolina.[8] As Colin made landfall on the Carolinas on the Fourth of July weekend, multiple events in Charleston were cancelled due to flooding at event grounds. A planned festival for the Fourth of July in Southport was called off as well.[9] Tropical Storm Warnings was issued for many areas of North and South Carolina, from South Santee River to Duck, North Carolina. Most of its heavy clouds went out in the ocean due to wind shear.[10] Four inches of rain was expected in both Carolinas.[11]

During its developmental stages, Colin produced locally heavy rainfall and gusty winds in coastal regions of South Carolina. Charleston County in particular saw 6–8 in (150–200 mm) of rain, with a maximum of 7.59 in (193 mm) near Wadmalaw Island.[12][13] Coastal locales in the county saw frequent gusts to tropical storm-force, averaging 45–50 mph (75–85 km/h). Loosened by saturated soils, some trees were knocked over by the gusty winds.[12] Rainfall totals inland ranged from 2–3 in (51–76 mm) in parts of the Midlands of South Carolina to near 7 in (180 mm) around Charleston, South Carolina.[14]

An observation station along the New River in North Carolina measured 0.1 inches (2.54 mm) of rainfall within a period of three hours.[15] A gust of 49 mph (79 km/h) was measured at the entrance to Winyah Bay.[16] One person drowned off the coast of Oak Island after being pulled out by rip currents.[17] Even after Colin dissipated, rip currents caused by the storm still battered the coast of North Carolina.[18]
