It sure seems that way. Israeli military assessments are that there are now 16,000 poised and ready to fire as soon as Hizbullah are given the green light by Iran. These rockets are said to be able to hit all areas in Israel, even Eilat.
More than this is the positioning of Iranian trained troops on battle readiness and war footing south of the Litani and of course where is UNIFIL in all of this? Standing aside and letting the build up continue.
