Delta IV trajectory

Does anyone know the launch trajectory for the Delta IV Heavy/NROL-49
that's launching tomorrow from Vandenberg? I'm assuming it will be
heading south, but could it head north-west instead?

I went looking for any NOTAMs concerning the launch (they should be
warning aircraft to stay clear of the expected stage impact areas) but
they apparently don't have any up yet:

No. Orbital launches from Vandenberg are limited to azimuths of 147 to
201 degrees. (180 degrees being due south.)

"With a thunderous roar heard for miles around,
the tallest rocket ever launched from Vandenberg
Air Force Base blasted into outer space, hurtling
over the Pacific Ocean as it cut across the
afternoon sky.

At 1:10 p.m. Pacific time, the 23-story Delta IV
Heavy rocket lifted off from the base northwest of
Santa Barbara. A white plume trailed the massive
rocket as it ascended.

Standing 235 feet tall, the rocket was so large that
the blast reportedly was heard as far away as 50
miles. According to aerospace experts, the booster
was carrying a top-secret spy satellite for the
National Reconnaissance Office — the covert
federal umbrella agency that operates spy
satellites."

That or it's spying on those suspicious Martians! They've been in a War
of the Worlds with us before so we have to keep a close eye on those
guys.

Looks like ULA is going to have some pad tweaking to do after this.

Holy ****.
That's the same problem they were worrying about when they were going to
launch the Shuttle from that pad...hydrogen building up in the exhaust
pit and igniting; they are going to have to figure out a way to fix that
before they do another launch from VAB.
That's not just scorching the insulation, some of it is actually on fire
during the early ascent. There's video of the launch he

Note how much debris is getting shed from the rocket - damaged insulation?

I thought hydrogen flames were supposed to be invisible.
