Sorry if that’s long, TL: DR at end. After reading these to get some context... I would agree with the meteorologist (though railing on live TV isn’t the best way to approach the issue) since it’s Slight Risk for area in question... most of time with Slight Risk... yes, the storms tend to be severe sometimes but not particularly intense save for few cases with very isolated but quite powerful storms... so Code Red for Slight Risk seems unnecessary. With the stations I normally watch, they don’t usually go Code Red or something similar unless there’s at least Enhanced Risk, especially with overnight events. If they add Code Red for let’s say Moderate Risk, potential major ice storm, or prolonged period of moderate to heavy rainfall with no break, I get it. Slight Risk? Well that’s little overboard. I had few of my favorite stations go crazy one time when Knoxville got flash flood emergency in February earlier this year, and it made sense. However, they can still go Code Red on Slight Risk days when something unexpected happened. For example, we had a derecho pass through in East Tennessee on May 27, 2017. It was Slight Risk with no hatching for significant severe for E. TN then, but the station went Code Red that night when the approaching bow echo reintensified unexpectedly (as best as I can remember). I was at home while my little brothers were sleeping, and I’ve been watching the radar on livestream to kill some time so I can watch lightning show in a bit. My parents were out for some time. It was typical severe weather coverage, no panic or anything but just informing viewers on livestream about severe thunderstorm warnings. After bow echo crossed plateaus, winds went from 60ish mph to hurricane-force prompting the weather broadcaster to push Code Red at last minutes when radar started to show 70+, some 80+ mph winds and turd started to hit the fan. It resulted into widespread damages and power outages from 70-80+ mph winds (as determined by NWS meteorologists and indicated by radar too). Some areas became tent cities since so many trees fell. My parents just got back home in nick of time when power flickered and the power pole across the street went ka-blooney. So... launching Code Red was appropriate for that situation despite Slight Risk since there’s an unexpected intensification.
TL: DR- Agree with weatherman about Code Red on Slight Risk days, but there should be a few exceptions. Started off with “code yellow” Slight Risk with no hatching for significant severe in E. TN. on 5/27/17, bow echo unexpectedly intensified after weakening briefly and produced widespread 70-80+ mph winds in the region. Stations went code red at last minute. Derecho caused widespread damage and outages. Can’t make this s**t up.
