National Weather Service to Change Warning System

You've no doubt seen it on T-V or heard it on the radio -- a storm warning covering an entire county. But some counties are huge, meaning certain people are nowhere near the impending tornado, flash flood or thunderstorm.

So the National Weather Service is about to change things.

Starting in October, countywide severe weather warnings will disappear. In their place, the weather service will issue more specific warnings, using highways or other well-known landmarks to define the affected areas.

The weather service's director says the goal is to get more accurate information to people. He notes that in Texas, for example, some counties are bigger than all of Rhode Island.
