A low pressure area formed in the Bay of Campeche on November 26. The NHC gave it a 10% chance of formation within 5 days. However, convection increased, and Tropical Depression Twenty was declared the next day. It slowly organized as it moved northeast, and became Tropical Storm Teddy on November 29. In the eastern Gulf of Mexico, shear was decreased, which gave Teddy time to intensify. Teddy exploded due to warm waters, and became a Category 3 hurricane on December 1, the day after the end of the season. It managed to reach category 4 before it made landfall on Tampa, Florida.
