The National Weather Service is responding to criticism from New York’s governor.
Late Saturday, Andrew Cuomo said the NWS didn't indicate that the heavy snow bands would remain stationary and blast South Buffalo and the Southtowns with unprecedented snowfall.
Cuomo indicated that's a big reason why the state is building its own weather forecasting system, which he says will be superior to any other state system in the country.
"No one had an idea that it was gonna be that much snow that fast. Snow coming down at the rate of about five inches an hour, Cuomo said.
The NWS says its office issued timely and accurate forecasts for both heavy lake effect snowstorms, as well as the rain and potential flooding to follow.
The state had been planning to build a weather forecasting system since at least last year, but officials at the NWS says it is more of a monitoring system than a long range projection system, meaning the proposed system would not have helped much with last week’s storms.
The NWS provided the following forecast timeline to support their assertion that their forecasts were timely and accurate:
