Go around.
(It says in our manual that gusts shall be included, but may be ignored at the captains discretion when it is considered it will absolutely be of no operational signifigance, which I've yet to seen applied.)
Edit: the above is NOT the wording in the SOP, sorry for the confusion on my part. The wording is "when adhering to the wind limitations the Commander shall include gusts that might be present during operations but he may exclude reported or forecast gusts that definitely will not be a factor for a specific operation".
