Don’t let pets or children near flood waters, even (especially) if it looks shallow. You can drown in 2-3 feet of water. You can’t see debris or power lines. Raw sewage. No.

If this is your first hurricane, and you didn’t stock up, it’s not too late. Find any clean, empty containers and fill them with water.

If you go the bathtub storage route, avoid using this for drinking water unless necessary. Save to flush toilets, rinse.

To purify water: 1 qt water, add 3-5 drops of bleach (5 if visibly cloudy). Let stand 30-60mins (60 if cloudy).

You want to store a gallon of water per person per day. If you have plain bleach on hand, you can use to purify water if no power to boil.

Standing water is dangerous (sewage, power lines, debris, manholes). Clean water is precious: 3-5 drops bleach to 1qt water.

If you have to go the bleach-purifying route, coffee filters for obvious particles, then plain bleach. Let stand 30-60 mins.

If your district issued a ‘do not consume’ order on tap water, neither bleach nor boiling will work: don’t even brush your teeth with it.

Pets need water too. Easy to underestimate when setting aside the gallons. Aim for at least 1 gallon/person day. 3 day supply minimum.

In a pinch, baby wipes and makeup removing towels make reasonable bath substitutes. Hand sanitizer on tissue works too.

If your home’s been under water, be super careful with appliances/power. Look out for any sign of dampness near the cables/outlets.

Don’t try to handle any plugs/appliances that have been exposed to or submerged in water.

Look out for any signs of soot/blackness/charring near electrical outlets. If you hear a pop or crackle, step away.

If your home’s been under water, even a little bit, assume everything’s been covered in sewage. Gloves/plastic bags if you’re cleaning up.

Bin any food that’s been exposed to flood waters, even if in foil/plastic. Remember: sewage.

If you live in an area where there’s been flooding, definitely worry about vermin. Cover everything. Double bag any compost/food remains.

Flashlights are useless if you can’t find them. Keep them close. Stick cash, ID/important documents in a ziplock bag. Medicines too.

Don’t have a flashlight? If you’re a runner or a cyclist, grab any headlamps/taillights you might have handy.
