They tweet at 730 but do the text alert at 815. What is the point? If cf has it discussed for 30 minutes before your alert goes out that is a problem.
IIRC, it takes quite a while for the alert system to send out the info to all of the contacts. When we had the pickup truck on central campus the emails went out within a couple minutes, but the texts and phone calls took a while.
