Upper Level Winds are NO GO. New T0 of 09:34 EST (1434 UTC)

EDIT to add:
Good time to remind everyone that Falcon 9 launch weather forecasts DO NOT include Upper Level Winds - the limits of which are mission specific and analyzed by SpaceX, not the 45th Space Wing of the Air Force.

Apparently, launch window has also been extended to 09:37 EST (1437 UTC) - so with our 09:34 EST (1434 UTC) new target launch time, that leaves 3mins of wiggle room for Falcon 9 today.

Current Upper Level Winds over Cape.

No. We are still further out than that. We have about 6 more minutes to go before that.

T-40 minutes. SpaceX Launch Director should be verifying go for propellant load. (hopefully!)

GO for propellant load!

T-35min and COUNTING. RP-1 kerosene and Liquid Oxygen are now flowing into Falcon 9's fuel tanks.

Teams have received their standard "what to do in the case that an urgent need to abort the count - including Upper Level Winds breaching safety limits - arises."
