PHOENIX — More monsoon storms are possible across Arizona tonight and tomorrow.
Watch out for strong winds, blowing dust and low visibility, dangerous cloud-to-ground lightning, heavy downpours, and flooding (especially near wildfire burn scars).
The threat for flooding will be highest near the Grand Canyon. Flash Flood Watches are in effect tonight through tomorrow for this part of our state including areas in Mohave County and Coconino County.
Make sure to download our free ABC15 mobile app or have another way to get warnings if you are in this area. Be prepared to take action should warnings be issued and even consider changing your plans if they include hiking, boating or paddle-boarding in a slot canyon or normally dry wash. If you do still decide to go, check in at a nearby visitor center or ranger station before heading out.
Back here in the Phoenix area, there is still a chance of a few showers and thunderstorms in the forecast. Our best chances will be Thursday afternoon and evening.
With this increase in monsoon moisture, we are also getting a break from the extreme heat. Daytime highs are dropping to around 105 to 107 degrees for the rest of the week and weekend ahead, which is near normal for this time of year.
There is no break from the triple-digits, though. Phoenix continues the longest stretch of triple-digit days ever recorded. As of Wednesday, we've had 87 triple-digit days in a row. The previous record was 76 consecutive triple-digit days set in August of 1993.
Heading into the weekend, a storm system moving through the Pacific Northwest will pull drier air into Arizona. That will clear out monsoon storm chances across most of our state.
