The National Weather Service (NWS) launched a new system on October 1 that allows meteorologists to pinpoint more specifically where a storm warning should be issued. Previously, NWS issued severe weather warnings by county. But storms are frequently smaller than the size of the county, and forecasters had to warn more people than necessary. The new system, called Storm-Based Warnings, uses a computer program to show more precisely the direction of a storm and indicate specifically what areas within a county are at risk. The new technology is based on a greater understanding of how storms develop and move.
