Weather Drivers: Hurricane Polo Remnants and Texas Flash Flooding
The severe disruption across Texas airports stems from tropical moisture from the remnants of Hurricane Polo pulling Gulf moisture over northern and central Texas. The National Weather Service issued flash flood warnings, flood warnings, and flood watches across the Greater Dallas-Fort Worth metroplex.
Simultaneously, non-weather operational constraints exacerbated national delays:
- Chicago O’Hare (ORD): FAA enforced ground stops due to low visibility and heavy rainfall.
- San Diego (SAN): FAA instituted an airport-volume ground delay averaging 31 minutes per arrival.
- Boston Logan (BOS): Active runway construction reduced hourly airfield capacity, prompting FAA ground delays.
