PHOENIX — For the third time this week, parts of the Phoenix area were left drenched by a monsoon storm on Wednesday.
The National Weather Service said parts of the US 60, which runs along the Mesa-Tempe-Gilbert border, were getting storms leading up to rush hour on Wednesday.
Other areas in the southeast Valley were also getting rain.
Wednesday’s storms were unlikely to be as heavy as those seen in the Phoenix area on Tuesday.
Unusually heavy rains left most of the downtown area with lots of puddles and even closed down Interstate 17 at Indian School Road. The area under the overpass flooded.
It took hours for the highway to reopen.
Multiple streets were flooded around the city. Local fire departments conducted at least two water rescues.
Monday’s storms were also tame. Showers were reported across Phoenix, thought flooding was not widespread.
This week’s storms came during a period of “excessive” moisture in the air, according to National Weather Service meteorologist Hector Vasquez.
“We’re in the excessive … monsoon moisture, which only happens a few times during the summer,” he said.
The monsoon weather is expected to move out of the Phoenix area by the weekend.
“Thursday and beyond, it looks like a westerly flow is coming off the Pacific and it should push most of the thunderstorm activity into eastern Arizona by the weekend,” Vasquez said.
After the storms move away, the temperatures will increase. The weather service is calling for a high of 105 degrees on Friday.
