Input: Question: Is a tropical depression stronger than a tropical storm? Passage:The formation and development of Hurricane Audrey was multi-faceted. One contributor to Audrey's formation—an area of anomalously low pressures roughly above sea level—was traced back to its first detection in the western Caribbean Sea on June 11. In an analysis of weather patterns from June 1957, Weather Bureau meteorologist William H. Klein noted the potential for research on similar disturbances to shed light on tropical cyclone development. Concurrently, surface observations suggested the progression of a disorganized tropical wave tracking westward across the Caribbean Sea beginning on June 20, eventually entering the Bay of Campeche on June 22. At 12:00 UTC on June 24 (7:00 a.m. CST), the resulting disturbance organized into a tropical depression based on ship reports in the bay; at the time, the first indication of a developing tropical cyclone originated from a report from a shrimp boat. The depression was in a highly favorable environment for intensification in the western Gulf of Mexico; sea surface temperatures in the area were at , or 3 °F (2 °C) above normal for the time of year. In addition, the latitudinal alignment of a polar trough over the Great Plains and the nascent disturbance in the Bay of Campeche created an environment suitable for outflow in the upper-levels of the atmosphere. Taking advantage of these conditions, Audrey reached tropical storm strength just six hours after being classified as a tropical depression while remaining nearly stationary.
