Storm type
Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionOn August 16, the National Hurricane Center (NHC) began tracking a large tropical wave that had emerged off of the West African coast, and began traversing across the Intertropical Convergence Zone (ITCZ) toward the Windward Islands.[1] En-route to the Windward Islands, satellite imagery revealed that the system began to close off its low-level circulation center (LLCC) with convection firing up around it, and subsequently the NHC began issuing advisories on Tropical Depression Thirteen on August 20.[2] On the next day, Thirteen strengthened into Tropical Storm Laura, but was unable to strengthen any further, due to congestion of upper-level dry air as well as land interaction.[3] This made Laura the earliest twelfth named Atlantic storm, beating the previous record of Hurricane Luis of 1995 by eight days. As Laura moved just offshore of Puerto Rico, a possible center reformation occurred to the south of Puerto Rico,[4] allowing Laura to begin strengthening.[5]
