ADDED: Upgraded to Tropical Storm Julia at 13/03Z.

Best Track data indicates Invest 93L is now a Tropical Depression located at 12.5N 20.8W at 12/12Z with sustained winds of 30 knots and a pressure of 1006MB. Since initial movement will likely be more to the northwest, Tropical Storm Warnings for the Cape Verde Islands are probably appropriate when advisories are initiated at 12/15Z. Some of the models bring the TD to hurricane strength on Tuesday. Movement beyond three days gets a bit problematic as the intensity and track could be influenced by the strong outflow from Igor and a weaker system might eventually move more to the west or west northwest.
