PHOENIX - We're expecting more rain in the Valley and snow in the high country. We have the latest weather updates below for the Phoenix area and northern Arizona.

Phoenix

In the Valley, scattered showers are in the forecast through Wednesday.

A cold front moving from the west will bring moderate rainfall to some parts of the metropolitan area.

Just north of the Valley, a Flood Warning is in effect for the New River until 9:45 a.m. as flooding in northern Arizona begins to move downstream.

Northern Arizona

Rivers rising

Salt River Project releasing billions of gallons of water

A new round of stormy weather is prompting officials with SRP to increase the amount of water released from its two reservoirs. FOX 10's Danielle Miller reports.

Salt River Project said storms have compelled the utility to increase the number of water releases from its two reservoirs on the Verde River. The reservoirs are already more than 80% full, officials said in a news release.

SRP says it will begin Tuesday releasing 16,000 cubic feet of water per second, which translates into 120,000 gallons (455,000 liters) of water per second. The number of cubic feet per second could go up more later in the week.

Recent surveys found that snowpack on the 13,000-square mile (34,000-square kilometer) watershed that feeds into those Verde reservoirs is the deepest it’s been in 30 years. SRP, which serves mainly central Arizona, operates by strategically releasing water from dams on the Salt and Verde rivers into a network of canals.

Water rescue in Cave Creek

Construction workers rescued from Cave Creek floodwaters

Two workers were rescued with help from Daisy Mountain Fire and Medical after their construction truck was washed downstream in Cave Creek on March 22.

Firefighters say two construction workers who attempted to get to a job site by crossing a flooded wash on March 22 in Cave Creek had to be rescued.

After driving their pickup truck into the wash, the truck was swept downstream with the men still inside. The men were able to climb out of the truck and onto the roof where they were eventually rescued, the Daisy Mountain Fire and Medical Department said.

The men were not hurt.

"Please do not cross flooded roadways, the risk is not worth your life and the safety of our rescuers," the department said.

Meteorologist tracking floodwaters

Meteorologists tracking floodwaters as it heads to the Valley

When the Arizona High Country gets big amounts of rain and snow, the moisture will eventually trickle downhill, and FOX 10's Marissa Sarbak has more on what meteorologists in the Phoenix area are doing to track the floodwater.

According to officials with Maricopa County Flood Control, this winter has been a wet one.

"There’s a lot of snow, especially above 6,500 feet right now. 200%-300% of normal. That snow is starting to melt. On top of that, we’re getting additional rainfall. The watersheds are wet. All of it comes down as runoff," said Maricopa County Flood Control Flood Warning Program Manager Daniel Henz.

Henz talked about the ways Maricopa County Flood Control monitors floodwaters.

"We have hundreds of rain gauges, stream gauges, gauges behind dams that are collecting data 24/7, sending it back here," said Henz. "Each one of those sensors has some kind of alert tied to it where we know 'OK, a water crossing might start to be filled, we need to notify City of Phoenix or City of Scottsdale."

The extra moisture, however, won't all go to the state's groundwater system.

"Most people see a lot of rain, a lot of surface water, and the assumption is that it's going to recharge the aquifer system, and in reality, it'll be less than 10% of that rainwater will make it to the aquifer," said Ryan Mitchell, Chief Hydrologist with the Arizona Department of Water Resources.

Like other officials, Henz also took a chance to warn members of the public about the dangers of floodwater.

"If we have a thousand cubic feet moving by every second, that’s basically a bulldozer or a full size fire truck that is pushing at you, every second," said Henz. "Your car has no chance against it. You have no chance against it."

FAQs

Will climate change bring more rain to Arizona? ›

The annual precipitation in Phoenix, AZ is projected to remain about 8.4". Extreme precipitation in any form can pose significant risks. Climate change is increasing the potential for extreme rainfall or snowfall because warmer air can hold more water vapor. See more information on storm risk.

Moisture can also move into Arizona from the eastern Pacific, the Gulf of Mexico, or even from the Sierra Madre Occidental forests in Mexico. A lifting mechanism is another ingredient needed for thunderstorm activity in Arizona.

Does true or false radar show you where there is rain or snow? ›

The reflectivity product will show where precipitation is occurring. Forecasters can see different storm attributes, such as hook echoes, bow echoes, and training echoes. All of these can be precursors to significant weather events.

Which weather radar is the most accurate? ›

The WSR-88D is one of the most powerful and advanced Weather Surveillance Doppler Radar in the world. Since first being built and tested in 1988, it has been installed and used operationally at over 160 locations across the United States, including Alaska and Hawaii.

Basic Monsoon Information

Officially runs from June 15th to September 30th. However, in northern Arizona, monsoonal moisture typically does not reach the region until the first week of July.

What rain doesn t show up on radar? ›

As the beam travels away from the radar source, it gets higher above the ground due to the curvature of the Earth. Therefore, if the precipitation is restricted to very low levels, especially within a few hundred feet from the ground, the radar beam might overshoot it, leading to undetected rainfall.

Why does weather radar show rain but it's not raining? ›

A phenomenon called "ducting" can cause the radar beam to be reflected toward the ground, showing non-existent precipitation. Ducting can occur in the early-morning hours if the surface temperature is cooler than the air aloft. Birds and bugs flying into the path of the radar beam may also produce false radar echoes.

Why does radar show snow but it's not snowing? ›

Precipitation is falling, just not at the surface. The reason we don't see snow at the surface on some occasions is due to the fact the air is too dry and as the snow falls, it evaporates and cannot penetrate the dry air mass that is in place. This is something called virga.

What color is a tornado on radar? ›

On a weather radar map, a tornado is usually indicated by a smaller area of red surrounded by a larger area of green. However, modern radar systems can also indicate debris balls, a sign of a tornado on the ground.

Is AccuWeather actually accurate? ›

Is there anything better than radar? ›

Lidar uses laser pulses to measure distances and create 3D maps, while radar uses radio waves to detect and track objects. Lidar offers higher spatial resolution and accuracy, while radar provides a longer range and better performance in adverse weather conditions.

Will climate change make it rain more? ›

Climate change can affect the intensity and frequency of precipitation. Warmer oceans increase the amount of water that evaporates into the air. When more moisture-laden air moves over land or converges into a storm system, it can produce more intense precipitation—for example, heavier rain and snow storms.

Where will climate change increase rainfall? ›

The Midwest and Northeast have experienced the strongest increases in heavy precipitation events. Scientists expect these trends to continue as the planet warms. For each degree Celsius of warming, the air's capacity for water vapor goes up by about 7 percent.
