PHOENIX - Sunday was another day of extreme heat across Arizona. Extreme heat warnings and heat advisories will remain in effect across the majority of Arizona through Monday.

Extreme heat blankets Arizona this weekend
FOX 10's Ashley Loaeza has more on our extremely hot temps this weekend and when we might see some relief from them.
Next Week:
Temperatures will start to drop little by little to start the work week, but another record warmest low could be seen Monday morning. Monday will be a mostly sunny day, with a high of 114 degrees in the Valley.
Storms will fire up across eastern Arizona, with widespread, scattered storms building in the southeast during the afternoon. These storms could send outflow boundaries toward Pinal and Maricopa counties, picking up dust along the way. This could lead to a potential dust storm, strong winds and even a couple of isolated storms during the evening. The best timing of impacts looks like 7 p.m. until 11 p.m.
Rain chances will increase across Arizona on Wednesday as moisture increases. This increase will cause the Valley to feel muggy again Wednesday through the weekend. It will also bring a better chance for evening/overnight storms in the Valley late this week. The entire high country will also see more widespread storms Wednesday through the weekend.
Higher humidity will also gradually lower the forecast high in Phoenix, with expected highs of 113 degrees on Monday, 111 degrees on Tuesday, and 108 degrees by Wednesday.
Friday and Saturday:
All of southern, central, and western Arizona were under extreme heat warnings. In central and western Arizona, many locations remain under a warning until Monday evening. In northern Arizona, many regional canyons and areas below 4,000 feet in Yavapai and Northern Gila counties will go under the extreme heat warning beginning Friday morning and lasting until Sunday evening. The Grand Canyon, below 4,000 feet, is also under the extreme heat warning through Sunday. An extreme heat advisory was in effect from Saturday morning through Sunday evening for Northeastern Arizona.

- If you are caught on a flooded road and waters are rising rapidly around you, get out of the car quickly and move to higher ground.
- Tune in to your local radio, NOAA radio, or news channels for the latest updates.
- If your neighborhood is prone to flooding, be prepared to evacuate quickly.

Preparing for a severe thunderstorm
The American Red Cross' tips for preparing for a severe thunderstorm:
- Put together an emergency kit.
- Know your community’s evacuation plan.
- 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 at least one gallon of clean water for each person in the household.
- 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.
