Tropical Storm Edouard disrupts U.S. flights

Tropical Depression Edouard was still threatening East Texas on Wednesday, September 2, while weather-related flight problems spread across major U.S. airports ahead of Labor Day travel. The Federal Aviation Administration said thunderstorm delays were possible in Houston and Philadelphia, and low clouds were forecast in Boston and the New York area airports. The National Hurricane Center said Edouard would continue to pose a threat for “locally extreme rainfall” in East Texas through Thursday morning. Flight-tracking data also showed widespread disruption across the national system. ### Why were Houston and the Northeast showing up at the center of the disruption? Houston-area airports were singled out by the FAA in its daily air traffic report on Wednesday. The agency said thunderstorm delays were possible at George Bush Intercontinental Airport and William P. Hobby Airport, listed as IAH and HOU. Philadelphia was also flagged for possible thunderstorm delays. Boston and the three main New York-area airports were listed under a different weather problem. (nhc.noaa.gov) The FAA said low clouds were forecast at Boston Logan, John F. Kennedy, LaGuardia and Newark on September 2. The FAA’s National Airspace System dashboard also showed active weather-related delay programs during the day, including a ground stop at LaGuardia due to thunderstorms and a ground delay at Philadelphia averaging 94 minutes. (faa.gov) ### What did federal forecasters say about Edouard itself? The National Hurricane Center said Wednesday that Edouard had weakened to a tropical depression. In its advisory archive and storm pages, the agency said the system would continue to threaten East Texas with heavy rain into Thursday morning. Flood watches remained in effect from the Upper Texas Coast into parts of eastern Texas, according to the public advisory. (faa.gov) At 10 a.m. CDT on Wednesday, the National Hurricane Center said the center of Tropical Depression Edouard was near 31.3 degrees north latitude and 95.0 degrees west longitude. That placed the system inland over Texas as aviation impacts were being felt at Houston hubs and in other weather-sensitive corridors. ### How broad were the flight problems nationwide? FlightAware’s public tracking pages showed nationwide delays and cancellations on Wednesday, though the site’s freely accessible pages did not provide a full storm-specific breakdown in the search results. (nhc.noaa.gov) Its airport and cancellation dashboards indicated ongoing disruption across the U.S. system, and its delay page showed more than 2,000 delays within, into, or out of the United States at one point. (nhc.noaa.gov) The FAA’s operational dashboard added airport-specific detail. Philadelphia was under a weather-related ground delay program, LaGuardia had a weather ground stop during part of the day, and other airports showed departure delays tied to weather or traffic-management initiatives. ### What does this mean for Labor Day travelers over the next day? Thursday morning is the next key point in the federal forecast. The National Hurricane Center said Edouard’s rainfall threat in East Texas would continue through then, and the FAA’s daily air traffic report and National Airspace System dashboard remain the main federal sources for same-day airport restrictions and delay programs.
