Here are some things to watch for at the GOP convention today:

1. WHEN THE RAINS CAME: Hurricane Isaac rolls toward the GOP convention in Tampa, Fla., threatening a thicket of wet, windy disarray depending on how and where it hits. The storm is on course to pass west of the convention city.

2. WAIT 'TIL TUESDAY: Republicans announce a leaner convention schedule to begin Tuesday - after canceling all events Monday except for a symbolic, 10-minute opening because of the approaching storm. How will a town full of eager delegates spend the day now?

3. NO BIDEN: Florida does without the nation's current vice president on Monday. Joe Biden scrapped a campaign swing through the state on account of the storm.

4. LOGISTICAL RESHUFFLINGS: Even with no formal convention events, lots of GOP luncheons and engagements are scheduled - and some are being relocated to accommodate possible inclement weather. Among the displaced happenings: a breakfast with New Jersey Gov. Chris Christie, and a brunch with former Secretary of State Condoleezza Rice and House Speaker John Boehner.

5. AND AN EXTRA DAY OF ANTICIPATION: Convention delayed will not be convention denied, say some enthusiastic participants. "We're ready to blow the roofs off on Tuesday night," says Mitch Zak, media director for California's GOP delegation.
