Here is an example where a DTA needs to be expired when the cell weakens.

2315-2345

This first image is from 2315z and it was looking good and properly tracking the storm.

BUT….the storm took a hard right and now here at 2345…this doesn’t exactly look correct…

Suggestion- if the storm weakens down a category, the alert needs to be expired. You can see that the alert dropped a level on the line track but I didn’t have the other colors overlaid so you can’t see that polygon. I was focused on the DTA.

Here is a radar loop of the progression.
