DENVER (AP) - The National Weather Service says its computer models made it difficult to predict the location and magnitude of heavy rains during Colorado's deadly September storms.
The agency issued a report this week assessing its performance during the storm. It says forecasters were able to give an average of 69 minutes' warning of flash floods. The national goal is 58 minutes.
The floods killed nine people and caused $2 billion in damage.
From 8 to 17 inches of rain fell in seven days along the mountains and foothills.
The report says forecasting models gave varying predictions on the time, location and magnitude of rainfall, making it difficult to provide accurate forecasts.
The report also cites problems with slow Internet connections.
