If we are in ruors let me highlight one point. The nature of gusts in storms are different than under normal conditions. Normally gusts going on top of the avarage wind. Reasons are termal lift etc. But in storm pressure gradients are so strong, not allowing higher velocities of wind. the reason for variation are frequently generated vortexes. For this reasons gusts in storms are always negative.
Thatswhy a correct wind report should readed as RCTP 270630Z 03086G62KT, not RCTP 270630Z 03062G86KT.
