What can go wrong in Detroit
- Basement flooding
- In June 2021, intense rain flooded thousands of basements and turned stretches of I-94 into lakes.
- Long outages
- Ice storms and summer storms regularly cut power to hundreds of thousands of customers for days.
- Extreme cold
- A winter outage can freeze pipes and make a house dangerous within a day.
- Severe storms
- Damaging winds and occasional tornadoes.
What that means for your plan
Protect the basement. A battery backup for your sump pump, a backflow valve if you're prone to sewer backups, and supplies stored on shelves instead of the floor prevent most of the damage.
Plan for a multi-day outage in any season: water, no-cook food, a power station, and in winter, sleeping bags and a battery CO alarm if you use any fuel-burning heat.
Never drive into a flooded underpass or freeway. Water is often deeper than it looks.
