The heavy rainfall and thunderstorms could lead to localized flooding in Phoenix, particularly in areas prone to water accumulation. Strong winds accompanying the storms may also pose risks to outdoor structures and activities. Rainfall totals exceeding one inch in some areas could disrupt travel and outdoor plans. Residents are advised to remain cautious, especially during periods of heavy rain, and to avoid driving through flooded roadways. The cooler midweek temperatures may provide some relief from the recent heat, but the return of triple-digit highs over the weekend will bring back heat-related risks.
