Observers urged for sudden changes in intensity as storms could produce strong wind gusts and localized heavy rain. Phoenix NWS continues to monitor radar trends and updates as conditions evolve. Travel impacts could occur in affected areas where convection forms. Keep monitoring for the latest advisories this afternoon. More updates are anticipated as the day progresses.
