What are the principles concerning the tefilah of atziras geshamim.
I have noticed that some kehilals are still saying this tefilah whereas others are not.
The basic principle is that after we commence saying the prayer, the prayer is recited continually until there is sufficient rainful. Because we (in Israel) have not reached this level, and remain in need of much rain, the prayer should still be said.
This ruling was given over in the name of Rav Elyashiv.
