​Phoenix Sky Harbor: thunderstorms trigger two FAA ground stops

On 16 September 2026, thunderstorms across the Phoenix Valley led the FAA to issue two temporary ground stops affecting traffic at Phoenix Sky Harbor International Airport (PHX). Local outlets (12News, KTAR, AZFamily) described monsoon-style storms, heavy rain and low ceilings as the operational trigger.

What travellers saw

Coverage reported an early weather pause on arrivals, then a second ground stop on departures in the early afternoon (around 12:45 local, lifted near 14:00 according to 12News). AZFamily also noted a noon–13:15 window with roughly 30-minute average departure delays while the stop was active. By the end of the day, 12News cited about 364 delays and 2 cancellations at Sky Harbor — always recheck your airline app, because knock-on banks can linger after the advisory clears.

If the schedule is critical

Build buffer for same-day PHX connections when monsoon cells are forecast. If you cannot absorb another bank of weather holds, a private jet or empty leg can avoid airline recovery churn. Rahizi qualifies the brief and returns partner options.
