Now targeting September 9 launch of Telstar 18 VANTAGE from Pad 40 in Florida. Rocket and payload are healthy; additional time will be used to complete pre-flight checkouts.

Countdown clocks at the Kennedy Space Center have been reset for T-minus 2 hours and counting, suggesting liftoff is now set for 12 a.m. EDT (0400 GMT).

@EmreKelly

No confirmation yet, but judging from countdown clocks at nearby KSC, SpaceX is now targeting midnight (0400 UTC) for #Falcon9 liftoff from CCAFS.

Weather radar from KSC. Non-professional opinion: sketchy.

A lightning advisory has been issued at the Kennedy Space Center after several storm cells popped up in the last few minutes over Cape Canaveral. The countdown clock continues ticking toward launch time of 12 a.m. EDT (0400 GMT).

T-minus 70 minutes and counting. SpaceX is holding off fueling at this time as foul weather impacts Cape Canaveral.

@cbs_spacenews

F9/Telstar18V: Now 45 minutes to launch at 12am EDT; lightning advisories are still in effect across Cape Canaveral
