DISPLACED WEST OF THE LLCC. THE INITIAL INTENSITY IS ASSESSED AT 30 
KNOTS HEDGING BELOW THE PGTW DVORAK CURRENT INTENSITY (CI) ESTIMATE 
OF 2.5 (35 KNOTS) BASED ON A CI ESTIMATE OF 1.5 (25 KNOTS) FROM DEMS 
AND 1.7 (27 KNOTS) BY ADT. TC 03A IS FORECAST TO TRACK WEST-
SOUTHWESTWARD ALONG THE NORTHERN COAST OF SOMALIA, DISSIPATING BY TAU
