Subtropical Depression One
A possible area of weather was found in the central Atlantic moving westward at 10 mph. The weather looked pretty organized so they gave it a 80% chance to form. The weather organized into Invest 91L moving northwest at 10 mph. 91L weakened a bit but then the NHC had seen that 91L was organizing really fast and on January 14, 91L had formed into Subtropical Depression One at 15:00 UTC. The NHC had issued advisories for Subtropical Depression One. This young depression was on news and they saw that it was moving northwestward for the east coast of South Carolina so they told South Carolina to watch out for this storm. The National Weather Service had seen the depression move towards South Carolina and started to issue watches for the east coast of South Carolina. After the watches issued, One started to move fast at 20 mph and 1 hour after the watches were issued, the watches turned into warnings. One made landfall on January 16 and after it made landfall, One started to rapidly decrease but One didn't dissipate because One looped back into the ocean before fully dissipating on January 17.

One had a peak intensity of 30 mph (45 km/h) making One a weak depression. The impacts of One were minimal and there was no damage reported during One. However, a 26 year old man had died while swimming in the ocean during One.
