Weather Safety Tips for Storms and Extreme Heat

Severe weather can develop quickly, and knowing what to do ahead of time makes a real difference. This guide covers practical weather safety tips for storms and extreme heat, including how to prepare before conditions turn dangerous, what to do while the weather is at its worst, and how to stay safe afterward. The advice below is general, so it applies whether you are at home, at work, or on the road.

Why Preparation Matters Most

Most weather-related injuries happen when people are caught off guard. A few simple habits reduce that risk: check the forecast each day, keep your phone charged, and know in advance where you would take shelter. Preparation takes only a few minutes, but it protects you when there is no time to think.

Watch vs. Warning: Know the Difference

Weather authorities use a few standard terms, and understanding them helps you decide how urgently to act.

Watch: Conditions are favorable for dangerous weather. Stay alert and be ready to act.
Warning: Dangerous weather is happening or is imminent. Act immediately.
Advisory: Conditions are less severe but still hazardous or inconvenient. Use caution.

Build a Basic Emergency Kit

An emergency kit should cover at least three days for each person in your household. Keep it in a place you can reach quickly.

Water: about one gallon per person per day
Nonperishable food and a manual can opener
Flashlight, extra batteries, and a battery-powered or hand-crank radio
First aid kit and a supply of any prescription medications
Phone charger, power bank, and copies of important documents
Whistle, dust mask, and basic sanitation items
Pet food and supplies, if you have animals

Storm Safety Tips

Before a Storm Arrives

Secure or bring inside loose outdoor items such as furniture, bins, and tools.
Charge phones, laptops, and power banks.
Identify a safe room: an interior space on the lowest level, away from windows.
Sign up for local weather alerts so you get warnings without waiting for the news.

During a Storm

Stay indoors and away from windows, glass doors, and skylights.
Avoid running water, plumbing, and corded phones during lightning.
Unplug sensitive electronics if you have time before the storm hits.
If you are outdoors, move to a sturdy building or a hard-topped vehicle. Avoid open fields, tall isolated trees, and metal objects.
If you are driving, slow down, turn on your headlights, and pull over only if you can do so safely, away from trees and power lines.

A useful rule for lightning: if you can hear thunder, you are close enough to be struck. Wait at least 30 minutes after the last thunder before going back outside.

After the Storm Passes

Wait for official word that conditions are safe before heading out.
Stay away from downed power lines and anything touching them.
Watch for debris, damaged trees, and unstable structures.
Check on neighbors, especially those who live alone.

Flood Safety Basics

Flooding causes more weather deaths than almost any other hazard, and most of those deaths happen in vehicles.

Never walk or drive through floodwater. Just six inches of moving water can knock you off your feet, and a foot of water can move a car.
Move to higher ground immediately if water begins to rise.
Avoid contact with floodwater, which may carry sewage, chemicals, or sharp debris.
Follow evacuation orders without delay.

Extreme Heat Safety Tips

Know the Signs of Heat Illness

Heat cramps: heavy sweating with painful muscle cramps. Move to a cool place, rest, and drink water.
Heat exhaustion: heavy sweating, weakness, dizziness, headache, nausea, and cool or clammy skin. Move to a cool place, loosen clothing, and sip water.
Heat stroke: very high body temperature, confusion, slurred speech, fainting, or hot skin. This is a medical emergency. Call for emergency help right away and cool the person with water, fans, or ice packs while you wait.

Stay Cool and Hydrated

Drink water throughout the day, before you feel thirsty. Avoid alcohol and heavy caffeine.
Wear light-colored, loose-fitting clothing and a hat.
Move outdoor work or exercise to the early morning or evening.
Take frequent breaks in shade or air conditioning.
Keep in mind that electric fans may not prevent heat illness in very high temperatures. Air-conditioned spaces, public cooling centers, or a cool shower are safer options.
Never leave a person or pet in a parked vehicle, even for a moment.

Power Outages: What to Do

Keep refrigerator and freezer doors closed. A closed refrigerator keeps food safe for about four hours; a full freezer holds temperature for roughly 48 hours.
Use flashlights instead of candles to reduce fire risk.
Run generators outdoors only, well away from windows and doors.
Never use a gas stove, grill, or camp stove indoors for heat or cooking.
Unplug appliances and electronics to protect them when power returns.

Protecting Children, Older Adults, and Pets

Check on older adults, infants, and anyone with a chronic illness at least twice a day during heat waves and after storms.
Offer children frequent water breaks and shade, and never rely on them to recognize their own overheating.
Keep pets indoors during storms and heat, and provide constant access to cool water.
Move pets to a safe interior room during severe storms and keep them away from floodwater afterward.

Make a Simple Family Plan

Choose a meeting place and a backup meeting place.
Write down emergency contacts on paper, in case phones lose power.
Assign one person to grab the emergency kit and another to secure pets.
Practice the plan twice a year, and review it when the seasons change.

The Bottom Line

Weather safety comes down to three habits: stay informed, prepare a small kit and a simple plan, and act immediately when a warning is issued. Storms demand shelter and distance from water and power lines, while extreme heat demands hydration, shade, and cooling. Taking these steps ahead of time keeps you and the people around you safe without added stress.
