The Atlantic’s first named storm of 2019 – Subtropical Storm Andrea – developed Monday evening southwest of Bermuda. Andrea marks the fifth straight year in which the Atlantic basin has had a named storm develop before the official start of the season (June 1). An Air Force Hurricane Hunter aircraft investigated the disturbance (90L) this afternoon, and found a well-defined circulation.

As of 6:30 p.m. EDT Monday, Subtropical Storm Andrea was centered near 28.8°N 68.7°W, and was moving northward at 14 mph. Maximum sustained winds were 35 knots (40 mph), with an estimated minimum pressure of 1006 mb. Interests in Bermuda should monitor the progress of Andrea. Andrea should continue moving northward for the rest of tonight, before abruptly taking a turn to the east on Tuesday.

Andrea is not likely to remain a subtropical or tropical cyclone for very long. Although some slight short-term intensification is possible tonight, wind shear is expected to quickly increase in about 24 hours while Andrea moves over cooler waters. It is not out of the question Andrea could transition into a tropical cyclone, but I do not think it has enough time. I think it is likely Andrea will become a remnant low before reaching Bermuda, though Bermuda could get some gusty winds and showers if Andrea persists for longer than expected. No watches and warnings have been issued for Bermuda as of this time.
