Jury selection was scheduled to begin Monday in Suffolk Superior Court in Boston, but was postponed Sunday as a heavy overnight snowstorm approached.
Prosecutors said jury selection would likely begin Tuesday.
Opening statements are slated for March 1.
Prosecutors plan to call Alexander Bradley as their star witness.
Bradley, a former friend of Hernandez, was with him in his car the night he allegedly shot de Abreu and Furtado.
Prosecutors say Hernandez shot Bradley in the face in 2013 because he was worried Bradley might implicate him in the double slaying.
Bradley survived, but lost his right eye.
Hernandez is charged with witness intimidation in the Bradley shooting.
Prosecutors have also said they plan to show jurors two Hernandez tattoos they say relate to the killings of de Abreu and Furtado.
