The National Weather Service is experiencing a major data outage that will affect weather warnings during deadly Midwest floods and a widespread heat wave.
Problems began around 5:30 p.m. EDT on Monday and are ongoing, according to NWS.
“The outage has caused impacts to NWS operations, including degradation of forecast and warning dissemination, disruption of data flows, and sluggish websites,” said NWS in a statement. Initial investigations revealed that it was caused by a network hardware configuration issue.
Heavy rainfall in the Upper Midwest led to dam failures and flooding in Iowa, South Dakota, Nebraska and Minnesota. More severe weather is forecast in the region for Tuesday.
