Looking Further Ahead:
More showers and storms are expected to move into south-central Arizona by early Monday morning. The Valley area and Casa Grande will see the chance for rain from around 5 a.m. to 9 a.m. Rain is most likely to track through the eastern half of the Valley.
Temperatures will climb from 86 in the morning to 103 during the evening, and the air will feel muggy. Drier skies are expected midday, and there will be more storms tracking through southern, eastern Arizona, along with the northern mountains, during the afternoon and evening. There is a chance for late afternoon and evening rain in the Valley, but it will be dependent on how well the atmosphere recovers from the morning rain.
Tuesday and Wednesday are expected to be the stormiest days of the week. Temperatures will bounce around the upper 90s and low 100s this week in the Valley. Rounds of rain will be possible each day, with the highest chance on Wednesday. Skies will be drier next weekend.

- Create a household disaster plan and practice it.
- Purchase a battery-powered or hand-crank radio
- Discuss thunderstorm safety with members of your household. Be aware that a thunderstorm could produce flooding.
- Pick a safe place in your home for household members to gather during a thunderstorm. This should be a place where there are no windows, skylights, or glass doors, which could be broken by strong winds or hail and cause damage or injury.
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.
- Have a first aid kit ready and accessible.
- 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.
