James Spann is “the man” for weather coverage in the Birmingham area. He recently posted some thoughts on his blog after the historic April 27 tornado outbreak.

James said he believes a high “false alarm ratio” over the years has led to inaction that could have cost lives during severe weather outbreaks. The “F.A.R.” for tornado warnings issued by the National Weather Service registers in the 80 percent to 90 percent category.

Small spin-ups from a squall line meet a danger category that prompts the National Weather Service to advance tornado warnings that activate weather radios, weather apps and in some locations — sirens.

The repetitive nature of the warnings jades the public, limiting action during real tornado emergencies. Spann said Facebook and Twitter could save more lives in the future.
