According to Jehovah's Witnesses is Jehovah God omnipotent, omniscient, and omnipresent? In talking to Jehovah's Witnesses I found it difficult to discover what they believed on these three attributes:
Omnipotent - God cannot be thwarted by the Devil, sin, sinners, or the world but is all-powerful in all things.
Omniscient - God knows all things about all things, past, present and future, all the time.  Nothing escapes his knowledge, including our thoughts &amp; motives.
Omnipresent - God is in all places, at all times, in the fullness of his being.  It is not just a bit of God everywhere, but all of God is everywhere all the time.
So he does not need angels or anyone else to inform him of anything anywhere at any time.
What is the Jehovah's Witness belief on these matters?
I will return later to flesh this out and look forward to your requests for clarification
We don’t teach that Jehovah is omnipresent.

We do teach that Jehovah is omniscient.
However when it comes to foreknowledge he does not choose to exercise it in all circumstances.

This article is very informative on both omniscience and omnipotence
Below is an excerpt.

Jehovah is also all-knowing, all-wise —omniscient. He can foresee whatever he wishes to foresee. Of him it is said: “There is not a creation that is not manifest to his sight, but all things are naked and openly exposed to the eyes of him with whom we have an accounting.” —Hebrews 4:13.


God’s omnipotence and omniscience make it impossible for him to fail. He always predicts the future accurately. Hence, he could say: “Surely just as I have figured, so it must occur; and just as I have counseled, that is what will come true.” (Isaiah 14:24)
