National Weather Service underestimated rainfall that triggered recent flash flood

Grand County has multiple alert systems to warn residents and tourists of local emergencies. On Friday, all cellphones within the identified high-risk area were pinged with a flash flood warning from the county. Residents not within the high-risk area did not receive the notification, leading some to believe the warning system failed, an issue the county ran into during the last major flood in August of 2022. But Cora Phillips, emergency management director for Grand County, said the system worked as planned, despite receiving inaccurate updates from the National Weather Service, which only predicted .5 inches of precipitation compared to the 1.02 inches Grand County received in just 15 minutes. - Show Notes - • MyAlerts App: https://apps.apple.com/us/app/myalerts/id1102847004 https://play.google.com/store/apps/details?id=com.AlertSense.PublicApp&hl=en_US&pli=1 • Grand County Alert Sense: https://public.alertsense.com/signup/?regionid=1367 • Grand County Emergency Management Facebook Page: https://www.facebook.com/GCSOEM Photo by Emily Arntsen/KZMU
