The Saffir-Simpson Hurricane Scale is a classification used for most Western Hemisphere tropical cyclones that exceed the intensities of "tropical depressions" and "tropical storms", and thereby become hurricanes. Source: Intellicast

Andrea Archive – 2019 Hurricane Season

Important Links: NHC Advisory Archive / NHC Graphics Archive
Duration: May 20 - May 21
Peak intensity: 40 mph (65 km/h) (1-min) 1006 mbar (hPa)

On May 17, 2019, the National Hurricane Center (NHC) began forecasting the formation of an area of low pressure south of Bermuda, which had the potential to later develop into a tropical or subtropical cyclone. On the following day, a large and elongated area of clouds and thunderstorms developed well to the east of the Bahamas. The disturbance gradually organized over the next two days as it moved westward and then northward, though it still lacked a well-defined circulation. However, an Air Force reconnaissance flight late on May 20 revealed that the storm had a well-defined center with winds reaching gale force, due to being involved with an upper-level low to its west, leading to the classification of the system as Subtropical Storm Andrea at 22:30 UTC that day. Soon afterward, Andrea reached its peak intensity. The nascent storm did not last very long, as the storm encountered dry air from the south, as well as southerly wind shear. These hostile conditions caused Andrea's convection to dissipate, and the storm degenerated into a remnant low early on the next day.
