Most of the windshear events on the east coast are just because of gusty, blustery winds and not because of convective activity. 40+knot winds are not uncommon in ORF or PHL or DCA or any of the other airports we fly to out here. If everyone diverted after a windshear two things would happen. One, you'd have dozens of planes per day trying to divert on windy days. Two, they'd just go to another airport that's likely no better. If one is bad on the east coast they are usually all bad.

In my experience though of flying the airplane nearly 6 years I have never once had a red windshear warning. Fingers still crossed. Keep the power up and don't try to chase your bugged speed. Just fly around 160 until your on about a 1 mile final and then start to reduce it. This way you have enough buffer to absorb a 15 knot reduction without having to use a lot of power, thus setting up a fluctuation of indicated airspeed, triggering a windshear warning or caution.
