The area of low pressure between Bermuda and the Azores that we have
been monitoring for a few days (90L) developed persistent deep
convection overnight. This is shown by the latest subjective Dvorak
current intensity estimate from TAFB of 2.0, and the current
wind estimate of 35 kt is supported by the past several
scatterometer passes showing 30 to 35 knot winds. Even though deep
convection is now decreasing, due to the persistent convection
overnight and pulsing convection over the past 36 hours, the system
has met the criteria of being classified as a tropical storm, albeit
a marginal one, making Tropical Storm Andrea the first Atlantic
storm of the year.
