Weather forecast appears unchanged, in terms of GO probability:

Falcon 9 and SES-12 went vertical this morning on Pad 40 in Florida. Weather is 70% favorable for the four-hour launch window which opens on June 4 at 12:29 a.m. EDT, or 4:29 UTC. spacex.com/webcast

It would appear to be a tad inclement at the pad currently:

What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

T-38mins

Teams are being told to report any constraints that would:
1) Prevent the start of Stage 1 LOX load
2) Prevent the start of Stage 2 LOX load
3) Prevent the start of Stage 2 RP-1 load.

Everything is very quiet on the LD loop -- meaning all is going perfectly to the timeline and autosequence with no issues at this time.

EDIT:  And VENTING!

T-20mins.  All still quiet and going perfectly.  Falcon 9 is venting away quite happily on SLC-40 as she comes to life.
