1. Before the storm hits, stop collecting wood, steel, and assign automatons to hospitals. Create more hospitals for each robot.
2. Try to keep steam cores - at least one, and preferably two or three.
3. Disassemble the Workshops when they have completed the Critical Storm Research Plan. The same goes for mines and other buildings that give you valuable resources such as cores, or that are near the generator and are no longer needed. Build more residential buildings instead.
4. Call all people off their jobs and send them home. Turn off heaters at all workplaces.
5. Remember your scouts. Bring them back home and don't forget to dismantle the camps, otherwise they will die even in the city when the storm comes.
6. When the frost hits, turn off the houses on the outskirts of the city (click on the house and then on the button in the upper right corner), and people will automatically go to the houses that are closer to the main generator. Do this until you see a sign that you have homeless people, and then start reassigning them to the homes that are closest to the center. Do this using the pause button, otherwise you may not be in time and the homeless will get sick.
7. When it comes to laws, you probably can't do it without a fully developed religion or order.
