Summertime can bring a range of weather challenges and potential dangers. Some of these threats can occur with little warning, so do what you can to prepare by assembling an emergency kit and forming a plan of action.

Find out what you should do if faced with the following weather dangers:

Lightning

In the U.S., lightning kills more people each year than tornadoes and hurricanes. If you can hear thunder, you are within striking distance and should seek shelter in an enclosed building or vehicle. While indoors, don’t use a corded phone, a computer or other electrical appliances; and avoid contact with plumbing (don’t shower, wash hands, do laundry, etc.). Learn more about lightning safety and get tips on what to do if you’re outdoors during a thunderstorm.

Floods

If you have time, move essential items to an upper floor. Do not touch electrical equipment if you are wet or standing in water. Do not walk through moving water that is six inches or higher. If floodwaters rise around your car, abandon the car and move to higher ground. Learn more about what to do before, during, and after a flood.

Hurricanes

If you can’t evacuate, get inside and secure external and internal doors. Stay away from windows and doors and take refuge in a small interior room, closet, or hallway on the lowest level. Learn more about what to do before, during, and after a hurricane.

Tornadoes

Storm cellars and basements are the safest locations, but if they aren’t available, go to an interior room, closet, or hallway on the lowest level. Stay away from windows, doors, outside walls, and corners. If you are in a trailer or mobile home, go to a sturdy, nearby building. Learn more about what to do before, during, and after a tornado.

Extreme Heat

Stay indoors as much as possible. Consider spending the hottest part of the day in an air-conditioned public building, such as a library or shopping mall. Never leave children or pets alone in vehicles. Learn more about what to do in extreme heat.

Wildfires

If your home is threatened by a wildfire, you must evacuate. If you have time, bring an emergency kit that includes copies of important documents. Learn more about what to do before, during, and after a wildfire.

Earthquakes

If you are indoors, stay away from windows, doors, and outside walls and get under a sturdy table or desk. If you are outside, keep away from buildings, streetlights, and utility wires. If you’re in a moving vehicle, safely stop the vehicle in an open area and stay inside. Learn more about what to do before, during, and after an earthquake.
