Driving in extreme temperatures

The Arizona Department of Transportation’s tips for driving in extreme temperatures include:

Protect yourself from the sun: In addition to an umbrella, bring sunscreen and a wide-brimmed hat, and wear loose-fitting, light-colored cotton clothing.

Refuel: Keep your tank three-quarters full. Running out of gas, especially in a remote location, is dangerous in extreme heat.

Hydrate: Bring a cooler to keep extra drinking water cold, and consider adding several frozen bottles of water to cool or thaw and drink as needed. Make sure everyone, including pets, stays hydrated.

Get help: If your vehicle breaks down in extreme heat, call for help immediately to shorten the wait time and turn on the air conditioning. If the air conditioning is not working, roll down all the windows.

Wait safely: If the temperature inside your vehicle becomes too high, everyone, including pets, should carefully exit and find or create a shady spot as far away from the traffic lanes as possible. Be careful when walking on the road surface, which can be hot enough to burn your skin. Keep your shoes on and try to keep your pets’ paws off the pavement. If you are stopped along the highway, raise the hood and turn on your hazard lights. Be aware that parking in tall brush can cause fires.

Check your vehicle: You can help prevent breakdowns and blowouts by making sure your vehicle is in good condition. Check your air conditioning and coolant levels, top up all essential engine fluids, and make sure your battery is topped up. Check your tire pressure, as the combination of underinflated tires and hot road surfaces can lead to a blowout.

Preparing for a severe thunderstorm

Tips from the American Red Cross for preparing for a severe thunderstorm:

• Put together an emergency kit.
• Make sure you are aware of your community’s evacuation plan.
• Create a household disaster plan and practice it.
• Buy a battery operated or hand crank radio
• Discuss storm safety with your family members. Be aware that storms can cause flooding.
• Choose a safe place in your home for family members to gather during a thunderstorm. This should be a place that has no windows, skylights, or glass doors, which could be broken by high winds or hail and cause damage or injury.

Be prepared and stay safe during monsoon

“Most Valley residents know how quickly and violently storms can come and go, bringing high winds, dust, rain and flash flooding. These storms can cause interruptions to services such as water, electricity and gas,” said Captain Ashley Losch of the Glendale Fire Department.

GFD reminds residents of ways they can be prepared and stay safe:

• Make sure you have flashlights with extra batteries on hand.
• Provide food that can be prepared without having to be cooked or refrigerated.
• Make sure that at least one liter of clean water is available for each family member.
• Provide an emergency power supply for anyone who needs power to run a medical device.
• Provide a backup power supply for cell phones that do not need to be charged.
• Make sure a first aid kit is ready and within reach.
• Never drive in areas with running water; it takes less than 10 inches to wash a car away.
• Avoid flooded areas, such as wash houses.
• When the water rises, seek higher ground.
• Do not stand too close to fallen power lines, as the ground can be live up to 60 metres away.
• Keep pets indoors during storms.
