There is no harm in watching for something and bracing for it's possibility. The harm comes when a possibility is NOT braced for and the consequences of it's reality catch you completely off-guard.

Could this be the event that caused men's hearts to fail them for looking at what is coming on the earth when the heaven's are shaken? (Luke 21:26) I guarantee you their hearts failed because they had not overcome their fear of this possibility and did not use this opportunity to strengthen their Faith that God would protect them as I and my family have done.

If this is nothing, our Faith has been strengthened and renewed so good has come from it. If it IS something, our Faith has been renewed and strengthened and fear will not overtake us when/if we see what is coming. Either way, we win! But only those who walk in the Truth of Jesus Christ. The rest will most surely lace up their Nikes and watch for the alien rescue vessel to arrive. Nothing ends well for those on the "broad path"!
