Like it was in the days of noah...

1. To the degree that one is able, take yourself to a relatively safe place at least by the time the rotation of the Earth occurs. The timing of this will not take you by surprise, as the inbound planet will be seen in the sky, unaided by telescope, for 7 weeks prior to the shift. The day of rotation stoppage is also not a surprise, as clocks and watches will be increasingly poky, and rotation takes a day to stop. Even if in the wrong place at that time, in that most of the population will be in shock but functioning, one could most likely travel on roads or even rails. Get going to your safe location, if not there already.
2. During the week of rotation stoppage, preparations not already made for the hour of the shift can be addressed, with rehearsals. On the long-day side of the Earth, it will seems like the worst mid-summer days, and on the long-night, colder than expected and one must deal with the dark, so anticipate these situations, depending upon where your location is. High winds are avoided by being at ground level, in a trench or under an overhang, or the like. Downpour, deluges, and flooding might occur, depending upon your location, so wherever you are riding out the shift should not be where you will be flooded or drown. Existing structures are best avoided, so do not plan on being in or under any existing structure. The least structure around you, the better, during quakes. Plan on being prone, not upright, so roll along the ground rather than being dashed.
3. Having established what you will do when the hour arrives, the next issue is to watch for the hour. Assign, among your group, at least one individual at all times to watch the skies and for signs. The tail of the passing planet will curve toward the earth, due to gravity attraction, so some red dusting will occur almost as soon as rotation stoppage occurs. But when approaching the hour of the shift, the tail lashing will get extreme, with not only red dust but gravel and hail falling. This is a sign that the shift is very close, within hours, and all should seek shelter under the sod or metal roofs they have constructed over trenches, or under overhangs. It is not necessary for all to be prone, for hours, if watching the skies is ongoing and by competent individuals. Children, in particular, should be allowed to release their energy in play, but keep them close and within voice call. The separating of the crust from the core is unmistakable, in that jiggling can be felt, and the stars or the Sun or whatever visible in the sky will move. It is at this point that preparations for the shift itself should be made.
4. Lie down, keeping children firmly in hand so they cannot panic and run out into the wind or lashing tail. Singing loudly in a group sing or some other engrossing activity will help in this regard, and keep the adults from panic also. Jolting and cracking of nearby trees will be felt and heard, and all should be ignored if the site has been well selected. At the end of the hour, it will be apparent that it is safe to emerge, as jolting will have stopped. A test can be done against the sky. Have the stars or the Sun stopped moving? Then the shift is past.
