MOST ACCURATE FORECAST: Strong storms and flash flooding hit Arizona

and last updated 2021-07-23 14:30:39-04

Monsoon storms will continue into the weekend and so will the threat of powerful winds and flash flooding.

High pressure is in position near the Four Corners, keeping monsoon moisture flowing in.

We're also tracking a disturbance moving across our state through Saturday that will provide a trigger to get storms going.

Any storms that develop could produce heavy rain and flash flooding, along with strong winds, blowing dust and small hail.

A Flash Flood Watch is in effect for Phoenix and most of Arizona through Saturday night, so we are now in ABC15 Weather Action Mode.

Take action now to prepare for storms, rain and flooding. Stay weather-aware and be prepared to seek shelter when storms strike.

With rain in the forecast, temperatures are expected to drop.

Look for highs here in the Valley in the 90s today, Saturday and Sunday, putting us more than 10 degrees below normal for this time of year.

Overnight lows will get cooler too with most Valley spots in the 70s early Saturday and Sunday mornings.
