• Five days in advance of the severe weather and three days prior to any other known source, AccuWeather exclusively predicted thunderstorms could bring damaging winds of 55-65 mph across the Northeast and mid-Atlantic on July 17.
• Four days in advance of the storms, AccuWeather was the only known source to predict a "moderate risk" of severe thunderstorms.
• From July 12 - 14, while AccuWeather predicted "storms can bring flooding and damaging winds," other sources, including the Storm Prediction Center (SPC), did not predict severe thunderstorms, stating "predictability too low" and "there is some limited severe potential across the Northeast." This did not convey the heightened risk and also did not mention the risk in the mid-Atlantic.
• On July 13, when the SPC first introduced a "marginal risk" of severe weather, it incorrectly did not include Virginia and North Carolina. AccuWeather had consistently included in these areas at risk since three days earlier. There were numerous wind damage reports in this region.
• AccuWeather forecasts for WABC and WPVI provided more specific information ahead of other known sources, better conveying the severe risk. As an example, on Saturday, July 13:
• AccuWeather predicted "a heavy afternoon or evening thunderstorm; storms can bring flooding and damaging winds."
• The National Weather Service forecast "a chance of showers and thunderstorms."
