Weather alerts around Phoenix should be specific enough to separate routine forecast changes from conditions that need action. June through September is the critical period for Phoenix, with dangerous heat early in summer and monsoon storms adding dust, lightning, and flood risk later.
Monsoon storms can be isolated and fast-changing, so radar, lightning context, and alerts help show which parts of the Valley are actually affected.
