Tropical Storm Larry was the twelfth tropical storm in the 2003 Atlantic hurricane season. It was one of eight storms to impact Mexico between the Atlantic Ocean in the season, a near-record. Larry formed in early October from an extratropical storm in the Bay of Campeche, and reached a peak intensity of 65 mph (100 km/h). Due to weak steering currents, the storm southward, resulting the storm to hit the Tabasco coastline, the first Tabascan landfall since Tropical Storm Brenda in 1973.
Larry drifted across the Isthmus of Tehuantepec, dropping heavy rainfall of over nine inches in places. The rainfall led to flooding and mudslides, causing damage to thousands of houses. The flooding killed five people and resulted in $53.6 million (2003 USD, $59 million 2005 USD) in damage. Larry was one of three tropical cyclones to hit Mexico in a short period of time, including Tropical Depression Nora and Tropical Storm Olaf in the eastern Pacific Ocean.
