- Purchase a battery-powered or hand-crank radio
- Discuss thunderstorm safety with members of your household. Be aware that a thunderstorm could produce flooding.

Be prepared and stay safe during the monsoon
"Most Valley residents know how quickly and furiously storms can move in and out, bringing strong winds, dust, rain, and flash flooding. These storms can cause interruptions in services, such as water, power, and gas," stated Captain Ashley Losch of the Glendale Fire Department.
GFD reminds residents of ways they can be prepared and stay safe:
- Have flashlights with extra batteries on hand.
- Have food that can be prepared without the need for cooking or refrigeration.

- Have backup power for anyone requiring power for a medical device.
- Have backup power for cell phones that do not require charging.

- Never drive into areas with flowing water; it takes less than 10 inches to wash a car away.
- Avoid flooded areas, such as washes.
- If waters are rising, seek higher ground.
- Do not approach downed power lines, the ground can be energized for up to 200 feet.
- Keep pets indoors during storms.
