Enlarge / Subtropical Storm Andrea, about 475km southwest of Bermuda, isn't much to look at. (credit: NOAA) On Monday evening, forecasters at the National Hurricane Center determined that a low pressure system in the Atlantic Ocean had sustained winds of 40mph, and therefore should be named Subtropical Storm Andrea. This was the first named storm of the 2019 Atlantic season, and it could bring some moderate rainfall to Bermuda on Wednesday before dissipating. Officially, the Atlantic hurricane season does not begin until June 1, and notionally ends on Nov.
