Noticed how a storm may briefly increase to 40 flashes/min, yielding a level 3 DTA for a cell. See the images below which highlight that although the DTA threshold was met for briefly for a few minutes, the successive flash rates dropped below the 40 flash/min threshold for minutes thereafter. The DTAs may be more useful for operational forecasters if the valid time were reduced from 45 mins to 30 mins. This would reduce the amount of products that may clutter up the radar interrogation process.
