FCOM 3.04.91 p3 - suspected windshear during approach (i would say gusty conditions qualify) ... Select FLAPS 3 and use managed speed in the approach phase.
also in p4 is mentioned "if downburst is expected, increase Vapp displayed on the MDCU up to a maximum of VLS + 15 knots".
Some don't like Flaps 3, some NEVER add any more speed in the app in stormy+windy days ... pilot preference
P.S. - i do
