Tropical Storm Ana
Unprecedented First Ever Atlantic Tropical Storm in April
In what could be a sign of a very active Atlantic hurricane season during 2003, Tropical Storm Ana developed in the Atlantic this week. While initially forming as a subtropical low over Atlantic waters, it has now acquired tropical characteristics. This TRMM overpass early on April 22, 2003 shows the detailed structure of Ana's swirling cloud bands and the nearly complete formation of a closed eyewall. The different colors indicate rain intensity, with reds being the most intense.
The official Atlantic hurricane season does not begin until June 1.
