Phoenix Monsoon Storms Cause Power Outages and Flight Delays

What Happened on Monday?

Monsoon storms (these are big summer rain and wind storms) moved into the Phoenix area, which people often call "the Valley."
This caused:

• Thousands of homes and businesses to lose power (no electricity!).
• Some flights at the airport to be delayed (planes had to wait).

Weather Warnings Explained Simply

The National Weather Service (the people who watch the sky and tell us what’s coming) sent out several alerts:

• Flash Flood Warning: For areas including Phoenix, Scottsdale, and Paradise Valley, lasting until 9:30 p.m. This means water could rise very fast and flood places quickly.
• Severe Thunderstorm Warning: For Phoenix, which ended at 7:15 p.m. This means there was strong lightning, thunder, and heavy rain.
• Dust Storm Warning: For the Phoenix area, in effect until 7:45 p.m. This is a big moving cloud of dirt and dust.

How Much Rain Fell?

A rain gauge (a tool that catches rain to measure it) in central Phoenix measured 1.26′ in just one hour. That’s a huge amount of water from the sky in a very short time!

Who Lost Electricity?

At one point in the evening, many customers of two power companies were without power:

• SRP (Salt River Project) customers:
  • About 15,000 in Maricopa County were without power.
  • About 10,000 in Pinal County also lost power.
• APS (Arizona Public Service) customers:
  • About 4,500 in Maricopa County were also in the dark.

Trouble at the Airport

As the storm rolled through, several flights at Phoenix Sky Harbor Airport were delayed. That means travelers had to wait longer than planned.
