Storm Forecasters Adding Extra Layers To Warnings

The Day 1 Convective Outlook - August 12, 2014
Storm Prediction Center National Weather Service

The Storm Prediction Center is adding two threat levels to its U.S. weather outlooks so people aren't surprised by really bad storms on days with just a "slight risk" of tornadoes, hail or high winds.

Beginning Oct. 22, forecasters can say whether slight risk days are "enhanced" or "marginal." Other categories remain, including "high" and "moderate."

The Norman, Oklahoma-based center proposed the change after finding that some days had conditions worse than a "slight risk" but not as bad as a "moderate risk."

The National Weather Service has been testing a new, simpler approach in different parts of the country, and last week, they introduced their system to Oklahoma.

The National Weather Service issued a report Friday examining last May's tornados in Oklahoma. The assessment encourages the Norman Forecast Office to develop a plan for more than one severe weather event at a time.

Use of these outlets explodes during severe weather outbreaks, as people try to disseminate information, share pictures and update each other on the course of the storm.
