So, what Webber is saying is that the low that is west of Irma is a TUTT (tropical upper tropospheric trough). Depending on what will occur with the TUTT, this will have an effect of the track of Irma. This weekend, both the TUTT and Irma will interact. I doubt that there will be a significant track change from it's WSW trajectory. Positive feedback and PVs in the downstream flow may break down the TUTT.
Even if the TUTT breaks down, I still don't think Irma will gain latitude before the islands due to the Atlantic ridge and the trough that will be over the east. That trough that will be over the east is still a big question rather or not it will lift before Irma gets closer to the EC if it does.
